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

<table>This figure compares the distance corrected near visual acuity (DCNVA) of 120 posthyperopic PRK eyes, which are also presbyopic (PRK group), and the uncorrected near visual acuity (UNVA) of 120 emmetropic presbyopic eyes (control group). The near visual acuity was found to be better to a statistically significant extent (<svg height="11.25" id="M13" style="vertical-align:-0.30096pt" version="1.1" viewbox="0 0 56.150002 11.25" width="56.150002" xmlns="http://www.w3.org/2000/svg">
