A comprehensive look on LASIK surgery

LASIK vision surgery is a simple procedure that is widely used to reshape the corneal tissue and correct refractive errors in the eye. This surgery is now considered by eye professionals as the most affordable and fastest laser eye surgery. Statistics show that approximately 99% of the patients can remove their corrective eyeglasses or contact lenses after the LASIK surgery.

During the LASIK procedure, the surgeon will create a flap on the corneal surface and lift it to one side. After that, a laser beam will be used to reshape the cornea under the flap. In detail, LASIK removes a stromal layer by flattening the curvature of the cornea. This removed layer has a thickness of 1/3 of the thickness of a human hair. Finally, the surgeon will roll back the reposition the cornea flap.

Although LASIK can always offer good visual outcomes, not all patients are eligible to this surgery. Candidates for LASIK must be at least 18 years old. Furthermore, they should have a normal corneal structure. Some patients who have certain conditions such as immuno-suppression and corticosteroid should be precluded because these conditions will affect the healing process after LASIK procedure. And LASIK candidates are required to stop wearing contact lenses several weeks before the surgery.

Laser-assisted In Situ Keratomileusis is much more popular than other laser eye surgeries nowadays. Other ones include photorefractive keratectomy (PFK), Radial keratomy and LASIK. As mentioned before, LASIK is quite faster than other procedures. In correcting residual myopia, LASIK surgery is very safe, stable and predictable. LASIK surgery involves less postoperative discomfort and only a few side effects.

Except for benefits or advantages of LASIK, it is equally important to mention its potential risks. Although they occur in rare cases, complications caused by LASIK are more severe than the ones caused by PRK. Any possible side effects as well as limitations of LASIK procedure should be explained to patients before the surgery.
