Chances are, you can have someone who has experienced Bell's palsy, or maybe even this common nerve condition experienced personally know. Bell's palsy causes sudden, temporary paralysis of the face or parts of the face from nerve damage. It 's the most common condition of nerve injury, that two out of every 10,000 people. The damaged nerve in Bell's palsy is called the seventh cranial nerve, and is responsible for the control of facial muscles.

Symptoms of Bell's palsyThis may deter, but are usually harmless

Sudden symptoms may include complete paralysis of one side of the face, often frightening, because it can look like a stroke or other more serious conditions. For this reason, you should seek medical attention to other diseases with similar symptoms.

While it may be scary to see the symptoms first person, this is not serious or life-threatening. Bell's palsy leaves alonein a few weeks or months. Unfortunately this also means there are no drugs or treatments to make way for Bell's palsy. Symptoms, mild or severe, can be unpleasant, there is usually feel an attempt to alleviate the symptoms, people with Bell's palsy do better.

The most common symptoms are spasms or weakness, or sensations of stiffness and dragging in the face, or complete paralysis on one side of the face. You can change the face of a slopingEyelids, a mouth drooping, eyes or dry mouth, drooling, and difficulty eating and drinking. Usually, these symptoms will go away. However, sometimes there are both short and long term complications. In the short term can lead to infections such as stomach ulcers and eye damage. Long-term changes may be on the face, tasting food and beverage issues, face and lower eyelids or cramps.

Bell's palsy: The drugs help?

Corticosteriodif in the first 24 hours after the first symptoms begin to take, can help relieve symptoms and reduce any swelling or pressure on the nerve. Antiviral drugs can be given to relieve symptoms and evidence, but there is no research showing that these drugs actually affect the course of time it takes to get out of a Bell's palsy. Eye discomfort is often a side effect of Bell's palsy symptoms. a bandage eyes and the drops can help, if not close the eyecompletely, or if the flash is a problem.

Other terms and cause for concern

Bell's palsy may be related to diabetes, Lyme disease, sarcoidosis, or head injuries. Blood tests, tests and imaging studies of the skull nerve and brain may help determine if it causes other serious health conditions of Bell's palsy, or if it is not Bell's palsy in all but a problem health, such as a stroke that caused the symptoms.

There is no doubt that ever improving optical technology has made our lives better in many ways. For those who can afford the procedures they can finally see what they have been missing. However, even though these procedures have proven to be accurate and quite successful; there are laser eye surgery risks that must be taken into consideration as well. Any surgery; regardless of how delicate or uncomplicated offers some degree of risk. Nevertheless, it is important that you don’t look the other way when it comes to the risks involved. They are very possible and extremely real.

There are laser eye surgery risks because this procedure; although not extremely complicated, is quite delicate to perform. Laser eye surgery involves the reshaping of the cornea in order to refract the focal point closer to the retina. Before we discuss the laser eye surgery risks; let’s examine the pre-determining conditions that could lead to problems and the requirements to even quality for the surgery. A successful surgery needs to be foregone by a successful screening process. Here are some of the requirements:

1. It is recommended that the patient be at least 19 years of old and in some cases 21 or older. For one reason; the eye, like other parts of the body, can still be changing up till that age. The other reason would be that some lasers require you to be 21 or older.

2. Basically you have to be in pretty good health.

3. You cannot be consuming certain prescriptions and you certainly cannot be on any type of steroids.

4. You should not be pregnant.

5. Your eyes should be in good health.

Your medical professional can confer and vouch for all of the above. They can also provide you with any information you might need to assist you in the decision making process. It is important that you know all of the risks involved before you sign upon the dotted line. Although these laser eye surgery risks may be minute; the fact remains they do still exist. Let’s take a look at some of the possible problems that could a rise:

1. There is always the chance that the surgeon could over or under correct. If this happens there is a chance that it can be corrected with future correction procedures.

2. Some of the procedures involve creating a flap that covers the cornea after the reconstruction. Some flap problems could occur where they are left irregular or cut off all together.

3. There is always the potential problem of corneal infection.

4. There is also a possibility that the cornea could become scarred or warped.

5. Your visionary contrast could become fuzzy and grey negating a sharp, crisp view.

6. Your night time driving could be affected to the point that you would need corrective lenses anyway.

7. Finally, your vision may end up worse then when you started.

As you can see quite clearly there are laser eye surgery risks that cannot be ignored. Although the chances of success are great; no one wants to become the unsuccessful statistic. If you are determined to have eye correction surgery that is perfectly fine. Literally hundreds of thousands of people now swear by the results. We simply recommend that you research your opportunities before you sign on the dotted line. It is vital that you know what your risks are because as we continually say; it is better to use your foresight successfully, rather than your hindsight when it is too late.

Laser eye surgery is used to correct such eyesight problems as myopia (short sight), hyperopia (long sight) and astigmatism.  Quite simply, a computer controlled laser beam is employed to correct the shape of the cornea – that part of the eye which has the job of ‘bending’ the rays of light which enter it, to produce our vision.   The procedure will permanently alter the patient’s cornea in a matter of minutes and the patient, after a day’s rest, will normally be able to go back to work with completely corrected vision.

In addition, corrective laser eye surgery can be used to treat and lower the intraocular pressure which can lead to the development of glaucoma; correct the degeneration of the macular, which affects many elderly people; and can also be used to counteract presbyopia, that blurred vision middle-aged people start to experience when trying to focus close up on reading books and newspapers.

There has been considerable attention during recent years to the laser eye surgery procedure known as LASIK eye surgery.  Lasik is the acronym for laser assisted in situ keratomileusis, which refers to the process of creating a flap in the cornea of the eye with a microkeratome, and then using a laser to reshape the underlying cornea.

Lasik surgery is a painless procedure in which a local anesthetic in the form of eye drops is used.  The procedure basically involves three distinct stages.   Firstly, a suction ring will be applied to the eye to keep it still and then a flap is created with a microkeratome- either mechanical with a metal blade or with a laser.  A hinge is left at one end of the flap, which is then folded back to reveal the middle section of the cornea, known as the stroma.

The second stage of the process involves an excimer laser remodeling the corneal stroma in order to correct the vision.  It is this precise reshaping of the cornea, restoring its power and focusing ability, which is so exciting about Lasik surgery.

The final stage of the operation is the repositioning of the flap, which will then remain in position through natural adhesion.  This means that no stitches or sutures are needed and, although a shield will be positioned over the eye for a while to help protect it, within a few days any blurriness or light sensitivity should have disappeared.

Lasik eye surgery is an exciting new development in the world of corrective eye surgery.  It is not usually considered for people under the age of 18, as their eyes are still developing. Because of the changes that can occur to women when they are pregnant or breast feeding, they also are generally not suited for this type of surgery.

Certain factors can cause poor drainage of aqueous fluids in the eye and this results in the build up of pressure which can cause damage to the optic nerves that helps the eye function for vision. This leads to an eye disease called glaucoma and if left untreated, it can cause permanent loss of vision. Through the years many techniques and procedures have been developed to diagnose and treat it and at this time the most promising solution is glaucoma laser surgery.

Glaucoma comes in different forms and determining what type of glaucoma a patient has helps in determining what treatment options there are. Initially, in an attempt to relieve pressure in the eye, doctors give eye drops and medication taken orally are given. If it does not help, then glaucoma laser surgery is the next option.

Argon laser trabeculoplasty is one form of glaucoma laser surgery technique used primary open angle glaucoma. Tiny burns are made into the trabecular network of the eyes to improve the draining and flow of aqueous fluid in the eyes. A specific form of this procedure is selective laser trabeculoplasty or SLT. This uses laser beams to remove only very specific target cells in the trabecular network. As a result, it improves the flow of aqueous fluids and relieves the pressure.

In some cases, it may take two sessions and in some, it may require repeating the procedure after two or three years. This, however is recommended because it avoids the need for medication after the procedure. It is also the glaucoma laser surgery procedure commonly recommended for pigmentary glaucoma which is common among males of African-American descent.

Angle closure glaucoma results if the space or angle between the iris and cornea is too narrow and this results in poor drainage of aqueous fluids. Peripheral iridotomy is the glaucoma laser surgery option for this type.

To relieve the pressure, laser beams are used to make a small hole on the iris. The space or angle widens as the iris moves away from it. This corrects the flow of aqueous fluids.

For more severe cases of glaucoma, the procedure usually recommended is laser cyclophotocoagulation. An example is when new blood vessels are formed in the eye as a result of diabetic retinopathy. The new blood vessels can seriously affect the flow of aqueous fluids in the eye resulting in pressure buildup. This leads to a form of glaucoma called neovascular glaucoma.

For this glaucoma laser surgery procedure, the doctor uses endoscopic cyclophotocoagulation to observe the ciliary body. This is also connected to an endoscopic camera. This will then guide the application of the laser beam to treat the ciliary body so it reduces or stops the production of fluids. By using a laser beam, part of the ciliary body is destroyed so that it no longer produces aqueous fluid. Less aqueous fluid means less pressure on the eye.

These glaucoma laser surgery procedures are usually painless. Some may feel a slight stinging sensation but apart from that, no major pain is felt. After undergoing glaucoma laser surgery, some rest for a few days is required and soon one can go back to the normal daily routine.

Also, in some cases, the patient needs to take some medication to relieve some minor discomforts that may appear after the procedure. Eye inflammation and slight risks in developing cataract may be some of the problems that may arise after each glaucoma laser surgery.

Glaucoma is a serious problem that can lead to permanent damage to the eye. It is important that it is well-understood and that a number of techniques are available to treat it.

Laser surgery is fast becoming a popular option for glaucoma treatment. The techniques are also becoming more and more advanced and refined to ensure that treatment results only in success and there is complete absence of discomfort during and after the treatment. They are also being improved to make the positive results long lasting, making glaucoma laser surgery a very promising form of treatment for glaucoma patients. As with any medical problem, thoroughly discuss all options with your physician.

Laser eye surgery comes at a high cost, and this is certainly a big factor for many people when choosing a laser eye practitioner. However, while finding an affordable vision clinic is important the biggest influence in your decision should be the ability and skill of the surgeon. Opting for a surgeon purely based on cost cutting may bring unsatisfactory results or, in the worst case scenario, lose you your sight.

The importance of finding a good surgeon

Only a minority of patients achieve true 20/20 vision, although most patients will experience a significant improvement in their vision which allows them to function on a daily basis without either contact lenses or glasses. However, there are also plenty patients who still require use of glasses after surgery despite an overall improvement in their sight.

There are several reasons for this. Firstly, if the procedure is not performed meticulously then over or under correction of the vision can occur. Secondly, it is common for laser eye surgery patients to develop very poor night vision and also see ‘halo’ effects appearing around lights. This will necessitate the use of glasses in low-level light conditions, especially when driving. Lastly, patients with extremely poor vision may be unsuitable candidates for surgery at all, as achieving ‘perfect’ vision may be implausible. While the nature of laser eye treatment means that the risk of these side effects or problems can never be eradicated, however skilled the surgeon, a good surgeon will vastly improve the chances of achieving a satisfactory outcome.

Another reason why it is imperative to find a reputable and highly skilled surgeon is that the procedure is not without its risks. Lasik is considered the most risky form of laser eye surgery, but is also the most popular due to its quick recovery time. In Lasik, a small incision needs to be made in the cornea to allow laser treatment to take place. If due care is not take, the flap may become detached. If the flap is also damaged, it might be impossible to reattach it to the eye. While improbable, full or partial vision loss can result from surgery. The likelihood of complications arising diminishes if you are in the hands of a highly qualified and experienced laser eye practitioner.

How to find a reputable surgeon

Your first step in finding a good surgeon should be to first find a reputable clinic. Be wary of vision clinics making outrageous claims such as ‘20/20 vision guaranteed’ or ‘perfect vision or your money back’. Before finding a clinic, research what can realistically expected from the laser eye surgery. If a clinic is making promises that they cannot guarantee delivery on, they may not be a good choice for your surgery. The best clinic is one which is honest about the potential results of laser eye treatment, both good and bad.

Compare as many clinics as possible. This does not just include the cost, although that is still a consideration for most people. Equipment can vary from clinic to clinic. Ideally, you should opt for surgery somewhere which provides the most up to date procedures and uses FDA approved equipment.

Ask your surgeon about his qualifications and training. It is also prudent to ask how many procedures he has carried out, particularly in the type of laser eye treatment you have opted for (for example Lasik or PRK). A good surgeon will be very thorough when discussing the procedure and will outline the potential risks, the side effects and what results you can realistically expect.

To locate a clinic or surgeon try searching the internet or asking your optician for a referral. American patients may also wish to visit American Academy of Ophthalmology’s website.

There are many cosmetic treatments available some involve surgical procedures such as a brow lift or a breast uplift. However, non surgical cosmetic treatments are a popular, non invasive choice for many people which do not carry the health risks associated with many surgical procedures.

Botox can be used to reduce wrinkles on the forehead, between the brows, the eye area and around the mouth. Botox can also be used the on lower face and neck area, usually this is used in conjunction with dermal fillers. Smiling or frowning is a result of a nerve signal from the brain, Botox blocks these signals which results in the skin becoming smoother and unwrinkled. The resulting smoother skin is noticeable after about eight days, although it can be a further two or three weeks before the full effects are seen. The Botox injections last for between twelve to sixteen weeks, however, with repeated treatments the effects begin to last slightly longer.

BioSkinJetting is carried out by beauticians, thin probes are inserted into a wrinkle and then agitated, this detaches the top layer of skin and encourages the production of natural collagen fibres. The developing fibres push the top layer of skin out reducing the appearance of the wrinkle. This non surgical cosmetic treatment takes less than an hour to carry out, but it may be necessary to have up to five sessions every two weeks before the wrinkles begin to fade.

Microdermabrasion is another non surgical cosmetic treatment which lessens the appearance of fine lines, uneven pigmentation, and blackheads. Microdermabrasion is used to realign the skin cells in the surface layer of skin and to stimulate collagen growth, which thickens the skin and can help to fight the signs of ageing, as well as help improve scarring.

Chemical peels can be effective surgical and non-surgical cosmetic treatments. Peels are designed to improve skin appearance, uneven pigmentation, acne scarring and are also used to reduce the effects of smoking and sun exposure. Chemical peels quicken the removal of old, dead skin cells to promote new cell growth. There are three types of chemical peels available; superficial, medium or deep. With all peels it is necessary to prepare the skin prior to the treatments to ensure that it is the best possible condition.

Superficial peels can be carried out by beauticians as they only remove the top layer of skin, however repeated treatments are usually necessary to maintain the effect.

Medium peels are carried out by doctors as they remove skin from both the top and middle layers, these peels last for between six and twelve months.

Deep peels have ‘lasting effects’, however they must be carried out by a surgeon or dermatologist as a local anaesthetic or sedative may be required. There will be peeling, redness and swelling which can last up from two weeks to three months depending on the individual and the type of peel used.

Although they are not as invasive as cosmetic surgery procedures, cosmetic treatments still require a great deal of consideration and can be expensive, however if treatments are needed to reduce scarring after trauma they may be included in the cost of the initial procedure.

What is a Laser?

LASER stands for Light Amplification by Stimulated Emission of Radiation. The first word is a good place to begin. A laser is a light. Not a light like the one in your living room, but a special kind of light. It has unique qualities.

Monochromaticity - A laser has only one wavelength or color. A regular light bulb has a range of wavelengths.

Directionality - A laser has a narrow beam which does not diverge. Compare a laser pointer with a regular flashlight.

Intensity - A laser is an extremely powerful light. A simple laser can produce light which is a hundred times more intense than sunlight.

These properties make the laser useful in light shows, war games, and incidentally, health care. Within medicine, lasers were first adapted for eye surgery.

The Excimer Laser

Lasers are differentiated from each other by the wavelength of their light beam. A laser generated from krypton gas produces light with a wavelength of 647 nanometers (nm). This wavelength falls within the visible spectrum of electromagnetic radiation and is seen as red. An argon laser which is used in retinal surgery has a wavelength of 514 nm and is green. A holmium:YAG laser with a wavelength of 2.13 micrometers is useful in the treatment of hyperopia.

The excimer laser uses a combination of argon and fluoride gases to produce radiation in the ultraviolet range (193nm) which is invisible to the naked eye. This laser light has the ability to break molecular bonds in a process called photoablation.

In 1983, it was first realized that this laser could be useful for corneal surgery. Why? Because this laser was different. Unlike other lasers, the excimer had the ability to remove corneal tissue with a high degree of precision, and equally important, without causing thermal damage to the remaining tissue. Sculpting of the cornea entered into the realm of possibility.

It is difficult, yet desirable, to comprehend the degree of precision exhibited by the excimer laser. A millimeter is one thousandth of a meter or four hundredths of an inch. A micron, or micrometer, is one thousandth of a millimeter. That is, one millionth of a meter. For the sake of comparison, a potato chip is about 500 microns thick, a human hair is about 50 microns thick and a single red blood cell is seven microns in diameter. The excimer laser has the ability to sculpt the cornea within a fraction of a micron.

Advocates of laser eye surgery point out that the steadiest hands in the world cannot even approach that level of surgical precision.

There are other kinds of lasers on the horizon which act in a similar fashion to the excimer. The light from these solid state lasers is produced from a crystal, whereas the excimer beam is created from a gas. Technically, solid state lasers are not excimer lasers, but that’s a whole new area to explore.

Laser technology has been one of technology’s greatest products that has positively improved the way things work. It has a number of applications and benefits, including in the field of medicine. An excellent example is laser eye surgery.

Laser eye surgery has given hope to people with eye problems, be it with vision or aesthetic aspects. For most people thinking of undergoing it, the first question is of course how laser eye surgery works.

Common problems concerning poor vision can be caused by distortions on the surface of the eye and its components. Light rays may be poorly reflected resulting in poor vision. This accounts for common vision problems such as astigmatism, near sightedness and far sightedness.

Some people also find wearing eyeglasses cumbersome while some even become self-conscious of it. Some wear contact lenses but still wish to go for a more permanent solution so they wouldn’t have to be so depended on it.

Laser eye surgery can be an option for this problem by helping correct the distortions and improve passing of light rays. Basically, what it does is to use laser beams to change the shape of the cornea to one that is most effective for vision.

So how does laser eye surgery work?

First, the doctor has to have a clear picture of the distortion. He uses an aberrometer. This also works by using a low- energy laser beam that is directed to the cornea, reflected and produces a 3D image on the aberrometer’s screen.

The most common form of laser eye surgery is LASIK or laser assisted in-situ keratomileusis. This laser eye surgery works by making a small cut to excise the top layer of the cornea during the surgery. It is mostly recommended because of faster recovery period.

Another option is photorefractive keratectomy or PRK. In this procedure, a portion of the cornea is scraped away and then laser is used to reshape the tissue underneath it. This was developed earlier than LASIK with LASIK being usually recommended because of its very minimal discomforts.

A fusion of the wonders of LASIK and PRK is Epi-LASIK or Epithelial Laser In-Situ Keratomileusis. This laser eye surgery works by making a thin flap of corneal epithelium using a microkeratome- like instrument. The underlying corneal layer is separated from the epithelium without cutting. It does not use alcohol solution to remove the epithelial layer. After this, the underlying cornea can be re-shaped to correct the distortion by using laser beam. Afterwards, the epithelium is restored to its normal position.

As was mentioned above, this laser eye surgery technique combines the benefits of the other techniques with less complications. After the procedure, the patient will be required to wear a thin, soft contact lens that will act like a bandage until the area heals completely. Healing and recovery is also faster and may only take around 3 to 4 days.

Laser eye surgery also works for more serious eye and vision problems such as diabetic retinopathy. Edema, swelling and leaking of capillaries in the eye that may accompany this complication of diabetes can make a person a potential candidate for laser eye surgery. This is to prevent more serious and permanent damage to the eyes that can lead to blindness.

Proliferative Diabetic Retinopathy (PDR) is the more serious and later stage of this disease where laser eye surgery is a more important choice of treatment. The technique for this is known as laser photocoagulation of the peripheral retina. The entire procedure may be completed in as short as 30-45 minutes per session. It may take around 3-4 sessions to fully benefit from this procedure with it being performed at the doctor’s office.

Laser eye surgery also works for age-related vision problems. One such technique is Photodynamic Therapy. This makes use of a light activated dye called Visudyne. This is introduced to the patient’s arm via injection. It enters the circulation and into the area beneath the retina where new blood vessels are formed. A non-thermal red laser is then used to activate Visudyne molecules. The activated molecules begin sealing holes and destroying unhealthy blood vessels.

Laser eye surgery can work miracles and provide new hope for people with vision problems of varying degrees. The key is to diagnose the condition and carefully evaluate which laser eye surgery technique will work best for the patient and you physician will do this for you.

LASIK is an acronym referring to the medical procedure of Laser Assisted in Situ Keratomileusis, which is intended to correct the vision of those who depend on glasses or contact lenses for flawless vision. It is a refractive laser eye surgery performed by ophthalmologists and is considered an ideal alternative to PRK, or Photorefractive Keratectomy. Compared to PRK, a LASIK surgery requires lesser time for recovery including the overall experience being painless.

In LASIK surgery, the shape of the cornea is permanently changed using an excimer laser. A microkeratome (blade) is used for cutting a flap in the interior area of the cornea. One end of this flap is left with a hinge and is folded back to reveal the middle section of the cornea known as stroma. The flap is then replaced when the pulses of the computerized laser, vaporize a portion of the stroma. However, according to research, there may be other techniques and new terms that are related to LASIK surgery.

Dr. Jose Barraquer first found the technique of LASIK. He developed the microkeratome in 1960 for cutting the thin flap of the cornea. Dr. Lucio Buratto and Dr. Ioannis Pallikaris developed LASIK surgery in 1990. A LASIK surgery is performed with the patient being full awake and mobile, however, with a mild sedative and anesthetic eye drops. Pre-operative screenings and comprehensive tests detecting the suitability and possible aftereffects of the surgery are performed and considered one of the crucial steps prior to the surgery. Although performed with success and ease on a number of patients, according to research, there have been cases wherein patients have developed several complications after the surgery resulting in repeated procedures of enhancement.

The complications following a LASIK surgery might include night vision, double vision, glares and halos to name a few. Proper follow-up care programs are essential for some patients, without which the patient may need to continue with their glasses and contact lenses even after the surgery. It is highly recommended to find out whether the patient is eligible for a LASIK surgery and try out the alternative ways. LASIK is not recommended for people below 18 and pregnant women.

Our eyes are one of the most important parts of our body. Being blind can definitely hamper our lives. That is why we take a lot of care with our eyes. But as we grow old there are problems that are being encountered with our health.

A lot of older people I know have undergone eye surgery. The cost of laser eye surgery nowadays is quite expensive. All of these do vary of course. Some are cheaper in other places and some might be expensive in your area.

Reasons Why There Are Different Cost of Laser Eye Surgery

1. Surgeon’s Expertise

Payments differ when it comes to the level of expertise of your chosen eye surgeon. If your surgeon has been practicing eye surgery for a few years, he certainly would be highly paid. If his reputation is highly recognized then he definitely will be expensive.

2. Technology

The cost can also be affected by the technology that will be used during the operation. The most expensive is the intralase. Of course, if you will compare a surgery that is using only a blade against surgeries that are using laser, it will definitely be much expensive.

3. Condition of the Eyes

If the eyes of the patient require a more complicated surgery, it will be expensive. The cost will differ when it requires more expertise and is a more difficult operation.

4. Region

The cost of laser eye surgery can also depend on the region. For example if the surgeon’s clinic is an expensive area. His fees will probably be also expensive. Of course, his practice also has its own expenses. Your surgeon also has to pay bills, rental expenses, his staff, and other miscellaneous expenses.

There a lot of advertisement about low cost laser eye operation is everywhere. There a lots of these advertisements, you can see them on magazines, leaflets, posters, and other media paraphernalia. A lot of people who have eye problems took this bait. As soon as the surgery is finished and the bill is presented, it is not what they expected. Apparently there were hidden costs that were not discussed.
