{November 9, 2010}   Lasik- right for you?

Tired of those boring spectacles which are ruining your beauty? Do you think contact lenses require a lot of meticulous work? Then,Lasik- right for you? you should start looking for alternatives.
While spectacles are the most common solution to those with myopia, hyperopia and astigmatism, recent developments in the field of medicine and laser treatment have opened up newer avenues. One such achievement is LASIK (laser-assisted in situ keratomileusis).

LASIK is a type of refractive surgery used for correcting myopia, hyperopia and astigmatism. Lasik is performed by ophthalmologists using a laser. Though similar to other forms of corrective surgeries, it provides more benefits like faster patient recovery.

Procedure
There are several necessary preparations before the surgery. The operation is about creating a thin flap on the eye, folding it to enable remodeling of the tissue beneath with a laser. The flap is repositioned and the eye is left to heal in the postoperative period.

People wearing soft contact lenses are instructed to stop using them 5 to 21 days before the surgery. The thickness of the patient’s cornea is checked with an instrument called the pachymeter and using a topographer a map of the cornea is created. This detects astigmatism and other problems. This map will help the surgeon in determining how the cornea is to be operated. The patient is asked to self-administer an anti-biotic to prevent infections in the postoperative period.
The patient is usually awake and mobile during the operation though he/she could be given a mild anesthetic. It is performed in three steps. The first step is to create a flap of corneal tissue. The second step is remodeling of the cornea underneath the flap with the laser. Finally, the flap is repositioned.

Antibiotics and anti-inflammatory eye drops are usually given to the patients. They’re asked to sleep for a long time and are given protective sunglasses to protect them from bright light and eye goggles to prevent frequent rubbing when asleep and to reduce dry eyes. They also are required to moisturize the eyes with preservative-free tears and follow directions for prescription drops. Patients should be adequately informed by their surgeons of the importance of proper post-operative care to minimize the risk of complications.

If you’re considering going in for LASIK, there are a few precautions you must take.

  1. If you play sports, this surgery could be risky, ditto if your cornea is too thin or if you suffer from some acute medical condition.
  2. Some jobs (pilot, police officer) require standards of vision that LASIK can help you achieve. Other jobs prohibit certain procedures.
  3. Medical insurance is not available for this kind of surgery and it doesn’t come cheap either.
  4. LASIK is not available to anybody who is below 18 years of age.
  5. In addition, if you’re over 40, you will still have to wear reading glasses after the surgery.
  6. LASIK can cause dry eyes and can aggravate your problem if you have dry eyes.
  7. There is also a possibility of surgical infection.
