Surgeons have been performing refractive surgery for many years, but during the past few decades, huge advancements have been made. The development of refined techniques and the emergence of laser vision surgery have substantially increased the success rate and effectiveness of refractive surgery.
One of the most groundbreaking advances occurred in the 1980s, when the excimer laser was developed. This laser allows ophthalmologists to remove very precise amounts of tissue from the eye’s surface during refractive surgery in order to improve the patient’s vision.
Refractive surgery is used to correct common eye disorders, such as nearsightedness, farsightedness, and astigmatism. Refractive surgery is designed to alter the shape of the cornea in order to improve the patient’s vision.
Although there are several types of surgical techniques being performed today to correct refractive errors, laser refractive correction has become the most common approach. Use of the laser allows for a great degree of precision and predictability in terms of the outcome for the patient.
The procedure is usually painless and the improvement in vision is noticeable almost immediately. In most cases, the patient can quickly return to their daily activities, but must avoid bumping the eye or submerging the eyes in water for a short period of time after the procedure.
