Dr Anupam Chatterjee, Pros and Cons of Laser Surgery

LASIK eye surgery is a procedure that treats nearsightedness, farsightedness and astigmatism. LASIK stands for Laser-Assisted In Situ Keratomileusis.

A laser or a surgical blade is used to cut a flap in the cornea. Then, a laser removes tissue beneath the flap, permanently changing the focusing power of the cornea, thereby improving vision.

Laser eye surgery is relatively painless, quick and convenient. There are two surgical methods from which to choose.

Do your research, ask lots of questions and follow all of the surgeon’s directives both prior to and following the lasik procedure to improve its effectiveness.

The Lasik Procedure
In order to access the stroma, the surgeon cuts a flap in the upper portion of the cornea, right above the pupil. Numbing drops are put into the eye, the cornea is marked to aid in replacing the flap, and then the eye area is cleaned.

A lid speculum holds the eye open. High pressure is applied to the eye with a suction ring that is briefly placed directly on the eye. Then the flap is cut. This is called a keratectomy, which may be done by either of two methods.

The time-tested way uses a microkeratome, a cutting instrument or blade. The newer method of cutting the flap is by “laser-only” or femtosecond lasik, sometimes known by the brand name “IntraLase”.

After the suction ring is removed, both lasik methods are nearly identical.

The corneal flap is folded back, and the exposed tissue is allowed to dry. Then, the patient is asked to stare at a light for about sixty seconds to help keep the eye fixed and immobile.

In less than one minute, the lasik computer pulses high-energy ultraviolet light removing the tissue that was previously determined to reshape the cornea most effectively and accurately.

The lasik laser makes clicking sounds, and there may be a smell of burning tissue. After very precise amounts of tissue are removed from the stroma, the surgeon lays the flap back into place. The eye is observed for a few minutes to make sure that proper bonding is taking place.

After Lasik Eye Surgery
Once the surgery is complete, a protective shield is placed over the eye, to prevent pressure and anything from bumping the eye. Since there are no stitches in lasik surgery, these precautions must be taken to ensure that the flap remains in place.

Some patients return to work the next day, but most doctors recommend that you wait a few days. Strenuous activity, and non-contact sports should be avoided for up to three days.

Facial products and makeup are out for up to two weeks. The eyelashes may need to be scrubbed fairly often during this time to help prevent infection.

No contact sports are allowed for at least four weeks. Expect to leave off swimming, hot tubs, whirlpools and saunas for up to eight weeks.

Expected Outcomes from Lasik
Most lasik patients see huge improvements in their vision by the next day. Vision may continue to improve for three to six months post-operatively. While visual fluctuations may occur temporarily throughout the day, this tendency diminishes over time.

If you have always dreamt of having 20/20 vision then it is time you learned about the pros and cons of laser eye surgery. This type of eye surgery is the latest development available to folks who have trouble with their eyesight. Are you tired of looking for your glasses every morning? Does the hassle of cleaning your contact lenses everyday bother you? If your answer is yes then laser surgery may be just right for you.

Laser surgery is a modern scientific discovery which sculpts the eye and corrects any defect. Also known as Lasik, laser eye surgery involves ophthalmologists peeling back the cornea surface to operate underneath and then returning it to its original place. Here is some information about the pros and cons of laser eye surgery.

Merits of Laser Eye Surgery

One of the most obvious benefits of laser eye surgery is better eyesight. You will not only be able to read traffic signs a long distance away but also the fine print written on contracts in your hand. Say goodbye to blurry vision.

The second benefit of laser eye surgery is that you no longer have to wear cumbersome accessories like glasses or contact lenses. There is no need to remember to pack your glasses, contact lenses, cleaning solution and cases along when you go on a vacation. You won’t have to bother to change from glasses to contact lenses to go for a party. Neither will you have to worry about the risks of falling asleep with your glasses or contact lenses on.

Of the pros and cons of laser eye surgery, another pro is the fact that this procedure can be completed within a day. All you need to do is to walk into a laser eye center and walk out without wearing your thick glasses the next day. People who have been known to be as ‘blind as a bat’ have come out of a laser eye center with as much as 20/15 vision.

Cons of Laser Eye Surgery

Now let us take a look at the ‘cons’ part of the pros and cons of laser eye surgery. An extremely tiny minority have found that this form of surgery did not suit them. Some complications include distortions of vision, such as irregular astigmatism, multiple vision, lack of color contrast and ‘dry-eye’ syndrome.
