LASIK and PRK Provide Similar Results
LASIK refers to the use of a laser to reshape the cornea without working directly on the outer surface of the cornea. Like LASIK, PRK uses a laser to reshape the cornea. However, PRK works directly on the outer surface of the cornea.
What makes one person a candidate for one eye correction surgery over the other is primarily dependent on their corneal thickness or any irregularities on or near the surface of the cornea, Dr. Alio said.
“The basis for any eye correction surgery is to reshape the cornea so that it changes the focal point of the eye,” he said. “Ideally, the focal point is changed so that it focuses perfectly on the retina.”
Dr. Alió said the data showed that PRK was somewhat more effective than LASIK for those with low levels of myopia, while LASIK performed slightly better for those with more severe nearsightedness.
He attributed these differences to the state of PRK technology ten years ago. According to Dr. Alió, recent improvements in PRK have made the two surgeries more comparably effective.
“With proper patient selection using today’s technologies, no one should harbor any doubts about the safety and lasting results of LASIK and PRK surgeries,” he said.
