Study shows myopic regression but no complications 7 to 8 years after LASIK
J Refract Surg. 2009;25(3):312-318.
Seven-year follow-up after LASIK showed slight myopic regression, but investigators were unable to determine whether regression stemmed from change in corneal curvature or power, lens power and/or axial elongation. Results showed no major postop complications and high patient satisfaction rates.
“Severe or late postoperative complications such as ectasia were not found and the postoperative satisfaction rate was high, despite the fact that emmetropia was often not reached,” the study authors said.
The retrospective follow-up study included 38 eyes of 21 patients with a mean age of 30 years.
Patients underwent postop follow-up at 2 months, 2 years and more than 7 years. Mean follow-up was 7.45 years (range, 6.7 to 8.2 years).
Mean preop logMAR best corrected visual acuity was 0.0. At final follow-up, 42% of eyes maintained preop BCVA, 34% gained one line, 18% lost one line and 5% lost two lines, the authors reported.
Forty-two percent of eyes had spherical equivalent refraction within 1 D of intended correction at final follow-up. Rates of myopic regression were greater for higher corrections (at least 6 D) and among patients younger than 30 years. All patients indicated they would undergo LASIK again, the authors said.
