Laser eye surgery

Laser Eye Surgery is one of the most advanced forms of surgery that has been developed and which is still undergoing dramatic improvements. Laser Eye surgery can be found in three main procedures; LASIK, LASEK and PRK. These are acronyms for those types of ophthalmological surgical procedures that are performed to correct vision defects such as myopia, astigmatism etc.

Laser Eye Surgery is much better than the conventional eye surgery because there is very small incision through which the surgery is done. Hence there is very little damage to tissue and hence there is less scarring, less time is required for healing and less chance for the surgery to go wrong because of human error. Also, the laser seals the capillaries and small blood vessels as it cuts through the tissue resulting in practically no bleeding.

Before the development of laser eye surgery such as LASIK, LASEK that are performed to correct vision defects such as myopia, there was no surgical method of correcting these defects. Eye glasses or spectacles or later contact lenses were the only solution to overcome these defects.

LASIK stands for ?laser assisted in-situ keratomileusis? which is basically a type of laser eye surgery that is performed to alter the shape of the cornea so that vision is improved. LASEK is also a type of laser eye surgery but different and distinct from LASIK. LASEK stands for ?laser assisted sub-epithelial keratomileusis? the third type of laser eye surgery is PRK or ?photo refractive keratomileusis?. There is not much difference between LASEK and PRK. Both these techniques of laser eye surgery permanently change the shape of the cornea to remove corneal defects and improve vision.

However, LASEK does not remove the epithelial layer of the cornea and the PRK procedure removes it.

Although laser eye surgery seems to be a guaranteed cure to vision defects, it is not without some complications that might occur after the operation and also some risks. Inaccurate correction of vision; over?correction or under-correction could be one of the risks because of which the patient is not satisfied with the results of the laser eye surgery that he has undergone. Dry eyes, sensitivity to light, double-vision etc. could be other complications of laser eye surgery that are experienced after surgery.

It?s important to consult and meet with you Laser eye surgery provider to understand the risks and benefits of the various procedures available. It?s also important to be screened to make sure that you are suitable for procedures and minimize any risks involved in your laser eye surgery.
