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

Abstract

Laser refractive surgery effectively treated all levels of myopia. Refractive stability was achieved within 1 year postoperatively, with LASIK showing better stability than PRK for up to 6 to 9 years.

Refractive Surgery: Part 1. Long-term Outcomes

“…3 The mean myopic regression in this study was similar to those in other studies: 0.5D over five years and 0.58D over 12 years. 3 In another study of highly myopic (-8.00D to -14.25D) LASIK patients in Germany, none of the participants lost more than two lines of BCVA and only 3% lost one line. 37 Half the patients gained a line of BCVA and only one complained of night vision problems.…”

Five year refractive outcome of LASIK for myopia and myopic astigmatism in Vietnam

“…At the fifth year, almost all eyes (95%) could be independent of spectacles with the UCVA of 20/40 or better. Our findings were close to the results of some studies (between 78% to 100%), 6,7,[9][10][11] but it more than double that in three reports (33% to 46%) which conducted on moderate to extreme myopia 5,12 (M. Elbahrawy et al, the XXXII Congress of ESCRS 2014). In our study, about three fourths of eyes in the mild and moderate group retained their UCVA of 20/20 at 5 years whereas this amount in the severe group was just over a half.…”

“…Our 0.5D refractive predictability result was similar to those of previous researches which range from 60% to 89%. [9][10][11] In terms of the 1.0D refractive predictability, although several studies showed comparable figures to us, 6,7,9-11 some six to eleven year follow up reports revealed a predictability of around 50%. 5,12,15 When looking at each group, severe myopic eyes had a less predictable outcome (70%) than eyes with mild to moderate myopia (from 84%).…”
