Abstract

Purpose. To assess near visual acuity in a presbyopic age group following hyperopic photorefractive keratectomy (PRK). Setting. Private practice in Siena, Italy. Methods. In this retrospective single-surgeon comparative study, PRK with mitomycin C was performed to correct hyperopia using Bausch & Lomb 217z laser for 120 eyes of 60 patients in the presbyopic age group (mean spherical equivalent SE +2.38 D ± 0.71 D and mean age 5 2 ± 5 . 0 9 ). 120 eyes of 60 age-matched controls (mean age 5 4 ± 5 . 0 9 ) had their unaided near vision measured. Results. At 12 months mean SE was −0.10 D ± 0.27 D in the PRK group. Mean best corrected visual acuity (BSCVA) was 0 . 0 0 5 ± 0 . 0 2 2 log MAR; 2 eyes lost ≥0.1 log MAR. Mean uncorrected visual acuity was 0 . 0 4 ± 0 . 0 7 7 log MAR. Mean distance corrected near visual acuity (DCNVA) in the PRK group was 𝐽 3 . 7 3 ± 1 . 0 6 . This was statistically better ( 𝑃 < 0 . 0 5 ) than the mean unaided near visual acuity in the control group 𝐽 4 . 0 7 ± 1 . 0 8 . Conclusion. PRK was found to be safe, predictable, and an effective way of correcting hyperopia in this age group. It was also found to give better than expected near vision.
