How Does LASIK Eye Surgery Work? Keratomileusis - The Carving Of The Cornea
By Nicola Kennedy
At present, LASIK or "Laser-Assisted In Situ Keratomileusis is the only commonly performed keratomileusis procedure. Keratomileusis involves an altering of the shape of the corneal tissue with the aid of an excimer laser, which is a powerful ultraviolet laser. This laser eye surgery is performed by ophthalmologists in order to correct different types of vision impairment. LASIK is the preferred treatment for patients with refractive error, since the procedure entails rapid recovery and minimal pain overall.
LASIK surgery leverages technology to its fullest. For instance, a computer system tracks the patient's eye position 4,000 times per second, while the lasers make the desired incisions. It might sound like a dangerous procedure, but it's time to debunk this myth. LASIK surgery is a completely safe procedure performed with high precision. That is, the laser carves the corneal tissue in a finely controlled manner. LASIK surgery is not that cumbersome when compared with other types of eye surgery, and has a relatively low frequency of complications.
Though LASIK surgery is performed with the patient awake and functional, the eye surgeon typically administers a mild sedative and anesthetic eye drops. No matter what the type of vision impairment, altering the shape of the cornea is a viable solution. In general, the procedure has very few side effects and offers instant results. However, a few complications may arise depending on the extent of the patient's refractive error and other irregularities in the corneal tissue.
LASIK eye surgery, with excellent technology at its disposal, is improving at a rapid rate. However, there is no conclusive evidence as to the chances of long-term complications owing to the surgery. Although relatively uncommon, a few complications may arise, namely corneal infection, slipped flap, haziness, halo or glare. An important point to note is that this laser-assisted procedure is irreversible.
LASIK has gained popularity due its efficacy and improved precision. The procedure also boasts of the smallest complication statistics relative to other eye surgeries. With only a 5% complication rate, LASIK sounds like a safe enough procedure to rectify your vision impairment.
