Distant objects look blurry. A farsighted, or hyperopic, eye is shorter than normal. Caused by changes in the curve of the cornea itself, astigmatism distorts the dight rays entering the eye and prevents them from focussing clearly. The excimer laser Developed in the early 1980s, the excimer laser is a proven and predictable tool for treating eye problems. Using pulses of high energy ultraviolet light, this unique laser can remove tisue without heating or damaging surrounding areas.
Precision is ensured because the laser is controlled by a specially programmed computer.
The PRK procedure PRK is usually performed on one eye at a time, but both eyes can be done if your ophthalmologist considers it appropriate for you. You will have appointments for eye exams, the procedure itself, and several follow up visits. During the procedure, an ophthalmologist uses the excimer laser to remove microscopic amounts of tissue from the cornea to correct irregularities and adjust the way light travels through the surface After PRK, there may be some discomfort, which usually lasts from 12 to 24 hours. Also your vision may initially be blurry, but you will begin to improve quickly. Some people find that glasses and contact lenses are uncomfortable , or they interfere with their professional, recreational or daily activities.
