Knowing about lasik eye surgery

Things you need to know regarding lasik eye surgery. You should first consult with your ophthalmologist to make sure that laser eye treatment is the suitable procedure for your eye condition.

The next thing you need to do is to find an ophthalmologic surgeon , the one will board certificate is preferable. Check about his or her credentials and experience Do you have astigmatism? If you have any of these eye disorders, lasik is really a good way to go for. If you really have severe myopia, you may need to take many lasik surgery.

Express your feeling or questions beforehand to your surgeon as he can explain to you in details before undergoing a lasik eye operation as you will be in a conscious position during the operation.

You should bear in mind that lasik eye surgery is not a miracle surgery. Do not expect that you will have perfect vision after coming out of the surgery with perfect vision.
Post-operative care is very important in the procedure of lasik surgery

eye laser surgery to correct common vision

Current info about eye laser surgery is not always the easiest thing to locate. Fortunately, this report includes the latest eye laser surgery info available.

Laser eye surgery is a surgical procedure intended to correct common vision disorders, referred to as refractive disorders in ophthalmology which include myopia or nearsightedness, hyperopia or farsightedness and also astigmatism or distorted vision.

Once you begin to move beyond basic background information, you begin to realize that there's more to eye laser surgery than you may have first thought.

The surgery intends to gently reshape the cornea by changing the thickness of the tissues of cornea. No matter whether you are far sighted or near sighted, the surgery will help your eyes bring the images into proper focus.
Due to such anomalies, light rays entering the eye don’t fall exactly on the retina thereby resulting in unclear vision. LASIK is a surgical procedure that aims to rectify these irregularities by reshaping the cornea.

One of the possible laser surgery complications that some people encounter is with their night vision. Although not usually severe, some people experience difficulty in seeing objects in low light situations such as night driving.

That's how things stand right now. Keep in mind that any subject can change over time, so be sure you keep up with the latest news.

eye laser surgery : Will it help with age-related vision loss?

Will it help with age-related vision loss?

No.

Laser surgery will not be able to cure age-related presbyopia and the need for reading glasses that people often develop in their mid-40's.

This is because presbyopia is not to do with a problem with the cornea. Instead, it occurs when the lens becoming less flexible with age.

Where can I get it?

Private treatment usually costs £1000-1500 per eye and is available at some NHS hospitals.

What are the risks?

Complications occur in less than 5% of cases, according to the Royal College of Ophthalmologists.

Some people have a problem with dry eyes in the months after surgery and artificial tear supplements might be needed in the long term.

Many patients have experienced glare or halo effects when night driving, particularly just after treatment. This is more likely the higher the correction that has been made, but is rarely severe.

In rare cases, excessive thinning of the eye wall can cause the shape of the eye to be unstable after treatment. Severe loss of vision is very unusual, but some patients could require corneal surgery or hard contact lenses to restore vision, it said.

Can both eyes be done on the same day?

Yes, but your consultant should outline the risks. In order to reduce the risk of cross contamination should complications arise, each eye should be treated as separate procedure.

How long will it take me to recover?

Most patients have a reasonably comfortable period after surgery and are back at work within a few days to a week.

Depending on the vision correction attempted, driving may be unsafe for one to two weeks. Tinted glasses with ultraviolet protection are needed when out in the sun for the first three months.

eye laser surgery : What does the surgery entail?

The surgery is intended to reduce a person's dependency on glasses or contact lenses.
Doctors use a laser to permanently change the shape of the cornea, the clear covering over the coloured iris, and the lens, which is just behind the pupil of the eye.

Doctors use a laser to permanently change the shape of the cornea, the clear covering over the coloured iris, and the lens, which is just behind the pupil of the eye.

What does the surgery entail?

The surgery is done as an out-patient procedure and takes about an hour.
Local anaesthetic drops are placed in the eye being treated.

A knife is used to cut a flap in the cornea.

A hinge is left at one end of this flap.

The flap is folded back to reveal the middle part of the cornea. Pulses from a laser vaporise a portion of this and the flap is replaced.

An eye patch is usually worn over the treated eye for 24 hours.

How does this improve vision?

People need to wear glasses for different reasons. Some people are said to be short-sighted or myopic. This is due to the cornea being too steeply curved or the eye longer than normal.

Therefore, light rays fall in short of the retina - the area at the back of the eye that interprets the image - and results in blurred distance vision.

Other people are long-sighted or hyperopic because their cornea is too flat or the eye is too short. This means that the light rays focus too far beyond the retina.

Others have a condition where the cornea is oval shaped rather than spherical, called astigmatism. This produces two different focal points which can blur images at all distances.

Laser surgery to reshape the cornea can help to correct these problems.

eye laser surgery : Can everyone have laser eye surgery

Can everyone have laser eye surgery?

No. Eye laser surgery is only suitable for certain people. It is usually only performed on healthy adults.

People who have just mild eyesight problems are not generally considered good candidates. Similarly, those whose eyesight has changed significantly in the past 12 months may also be refused because their eyesight is still getting worse.

Diabetes, pregnancy and arthritis and other similar conditions can also rule people out.

How popular is eye laser surgery?

Eye laser surgery is getting more popular every year not least because prices are coming down and the treatment is more widely available.

It is estimated that more than one million Americans are now having their eyes lasered in the US each year.

eye laser surgery : The Excimer Laser

The modern method of using the Excimer Laser to correct refractive errors is a breakthrough which can benefit millions of patients who are shortsighted or have other refractive errors. The technique has advanced to a point where we can reliably predict that Excimer Laser treatment will, in suitable patients, provide good vision without glasses or contact lenses. For people who undergo Excimer Laser procedures, less dependency upon corrective lenses is a major benefit.

Excimer Laser treatment is an elective procedure and, as with any form of surgery, deserves careful consideration prior to proceeding. Please contact us and we will answer any questions that you may have. We offer a free screening test and we also have educational videos for you to watch. If you are a good candidate for the Excimer Laser procedure, then the decision to go ahead is entirely yours to make.

The Excimer Laser was originally developed for the manufacture of computer microchips, where it was used to etch the circuits. However, its extreme accuracy resulted in it being developed as an eye laser. It is now used to re-sculpture the corneal surface of patients with refractive errors.

The Excimer Eye Laser is extremely accurate and removes only 0.25 microns (1/4000 th millimetre) of tissue per pulse. During the re-sculpturing the Laser gently "evaporates" tissue; there is no burning or cutting involved. In most cases the Laser treatment takes only 20 to 45 seconds depending on how severe your refractive error is. The Excimer Laser accurately re-sculptures the cornea to make the curve of the cornea balance the length of the eye, light rays are then focused normally on the retina.

In myopia the cornea is flattened (as shown above), whereas in hyperopia the cornea is made more curved. With astigmatism the surface of the cornea is re-sculptured to a regular curvature. This advanced surgical technique using the Excimer Laser can accurately re-sculpture your cornea thus permanently correcting your myopia or other refractive error - allowing you to be independent or less reliant on glasses and contact lenses.

In the original method of treatment the Laser was used on the surface of the cornea. This method is known as photorefractive keratectomy (PRK). Although still sometimes used for low degrees of myopia and hyperopia, PRK has been largely superseded by the Lasik method in which the Laser treatment is applied under a protective corneal flap

This is a modern adaptation, using the Excimer Laser, of a technique that has been in existence for almost 30 years. A thin protective corneal flap is raised, rather like a trapdoor. The front surface of the exposed cornea is resculptured by the Excimer Laser. At the end of the procedure the protective flap is simply replaced. The Lasik technique leaves the original surface of the cornea virtually intact, the mild healing process results in minimal regression and no scarring. The Lasik procedure is now regarded as the most advanced refractive surgery technique.
