Advanced LASIK surgery is used to correct refractive errors of the eyes like myopia or nearsightedness, hyperopia or farsightedness and astigmatism i.e. where both near and far objects appear blurred. This surgery is performed only on patients who are more than eighteen years old in age and have stable refractive power. However all eyes may not be suitable for performing LASIK surgeries. Only after examination of the eyes, the doctors take decision to go ahead or not.
LASIK surgery is a safe procedure approved by FDA of US. Minor problems may occur in about 3% of cases and major problems may occur in 1% cases.
Its cost may vary between Rs. 20,000 to Rs. 60,000 depending upon the procedure used, expertise of the doctor and type of hospital.

LASIK, pronounced Lay-sik is the popular surgery used most widely worldwide. It uses laser rays to correct eye problems. It can correct nearsightedness, farsightedness and astigmatism. The procedure creates a thin flap in the cornea.
In fact, it is outpatient surgery and as such it does not need you to stay overnight for the surgery. You will be asked to stare at the target light for a shorter time of duration. The laser sends pulses to your cornea to reshape it. The procedure is controlled by the surgeon by means of a computer. The surgery actually takes just under five minutes to complerte.
The surgery does not have many issues. Some of you may face the issue of dry eyes. However, the problem is temporary.
Flap complications can occur, but the possibility is just 0.244 per cent.

In addition to the information provided above, I would like to add that laser surgery corrects the shape of your cornea by ablating (removing/killing) some of the cells in your eye. This ablation is permanent and the cells that are lost by this method can not be regained. Therefore, while your vision will be restored due to the new shape of cornea however, it will not prevent your eyes from developing a power again due to old age or too much strain on the eyes.
If you don't want to wear glasses or contacts then another option would be to go for orthokeratology, also called as overnight vision correction. In this method, you wear Ortho-K gas permeable contact lenses at night before sleeping. These lenses push your cornea into the correct shape for perfect vision. When you wake up in the morning, remove the lenses and your cornea will retain the correct shape it was pushed into during the night. Therefore, you will have correct vision during the day. You have to repeat the process of wearing the lenses every night until your cornea starts remaining in the correct shape for longer duration. After that you can wear lenses every alternate night, or biweekly/weekly/fortnightly/monthly depending on your vision. This method has the advantage that you don't permanently destroy any eye cells. On the other hand disadvantages include having to wear them every night for a specified period of time and reversion back to incorrect vision by the end of the day.
