Nov. 13, 2006 — In the event that you’re considering laser surgery to redress your nearsightedness, you’ll rest assured that the comes about will final long term.
A group of analysts from Spain tracked LASIK surgery (laser in-situ keratomileusis) and its harbinger, PRK (photorefractive keratectomy). In both strategies, the cornea is reshaped so that light entering the eye focuses on the retina in the back of the eye, because it does in those with normal vision.
“Our discoveries are that both are secure after 10 years,” and the visual rectification holds for the most part, says researcher Jorge Alio, MD, PhD, an ophthalmologist.
The study was presented at the joint yearly meeting of the American Academy of Ophthalmology and the Asia Pacific Academy of Ophthalmology.
The 10-Year Consider
The consider evaluated 200 eyes with nearsightedness (astigmatism) or with nearsightedness and astigmatism, an irregularly molded cornea that obscures vision.
One hundred eyes were rectified with LASIK; the other 100 were corrected with PRK. Both methods use lasers.
On average, patients were 29 when the surgeries were done in 1995 and 1996, Alio says.
The researchers measured each patient’s vision 10 a long time later and assessed changes on the cornea, which reflect the steadiness of the strategy.
Most of the vision adjustment remained, he says. Ten a long time later, on normal, “they perused the line [on the eye chart] over what they used to read [quickly after the surgery].”
Put another way, he says, the vision of both bunches regressed only slightly.
These patients were exceedingly myopic to start with, he says. After 10 years, the PRK patients’ nearsightedness and the LASIK patients’ vision regressed as it were marginally, Alio says.
“Typically a very great ponder,” says James J. Salz, MD, a Los Angeles ophthalmologist and long-time vision redress surgery researcher. The results, he says, appear that both eye methods are “very steady” operations.”
While the patients got a bit more nearsighted — and the LASIK patients a bit more than the PRK patients — the comes about held decently well, he says.
