Overcorrection After Excimer Laser Treatment of Myopia and Myopic Astigmatism

Ten-year follow-up of photorefractive keratectomy for myopia

“…In our study, we found that 55% of eyes were within ±1.0D and 76% were within ±2.0D after 10 years, and predictability was better in the low myopia group. High myopia might lead not only to overcorrection but also to undercorrection; in that respect, our study was similar to previous studies [15][16][17]. Long-term follow-up studies of PRK have shown that refractive stability was achieved by 1 year and was maintained at up to 12 years with no significant hyperopic shift, late regression, or fluctuation [6,7,12].…”

Outcomes of laser refractive surgery for myopia

“…83,89,90 In our review, most studies of eyes with high to extreme myopia that were treated with PRK 29,30,70,71,73,76,79 reported 50% of eyes or more achieving a UCVA of 6/ 12 or better. The corresponding percentage in most LASIK studies 80,82,83 was more than 70%.…”

Long-term refractive outcomes and stability after excimer laser surgery for myopia

“…One month postoperatively, overcorrection was associated mostly with PRK and undercorrection with LASIK, which has been shown to be normal with earlier generation lasers. [19][20][21] Myopic regression occurred throughout the follow-up, from the first postoperative month on; however, none of the regressions was significant. Refractive stability was achieved 6 to 12 months postoperatively, and the mean myopic regression throughout the 13-year follow-up study was low (0.57 D) in the entire cohort.…”
