Near Visual Acuity Following Hyperopic Photorefractive Keratectomy in a Presbyopic Age Group

الملخص EN

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 52±5.09).

120 eyes of 60 age-matched controls (mean age 54±5.09) 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 0.005±0.022 log MAR; 2 eyes lost ≥0.1 log MAR.

Mean uncorrected visual acuity was 0.04±0.077 log MAR.

Mean distance corrected near visual acuity (DCNVA) in the PRK group was J3.73±1.06.

This was statistically better (P<0.05) than the mean unaided near visual acuity in the control group J4.07±1.08.

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.
