Abstract
Abstract: :
Purpose: To describe a series of four patients that underwent LASIK and developed a multifocal effect, resulting in the correction of their distance and near vision. Methods: Eight eyes of four patients underwent primary or enhancement LASIK for myopia or hyperopia and astigmatism. Results: Outcome measures included manifest and cycloplegic refraction with best spectacle corrected visual acuity (BSCVA), uncorrected distance visual acuity (UCDVA), uncorrected near visual acuity (UCNVA), and postoperative topography. At the postoperative examination ranging from 3 to 11 months (mean 7 months), uncorrected distance visual acuity of 20/25 or better, and uncorrected near visual acuity of J1 or better was found in all eyes. Conclusions: Improved uncorrected distance and near visual acuity after LASIK may be due to the multifocal effect of an off-centered ablation.
