Intentional Undercorrection by Implantation of Posterior Chamber Phakic Intraocular Lens With A Central Hole (Hole ICL) For Early Presbyopia

Purpose. To assess visual performance at near to far distances in early presbyopic patients with undercorrection by implantation of an ICL with a central hole (hole ICL). Methods. This prospective study evaluated forty-two eyes of 21 early presbyopic patients (age, 40 to 53 years) with spherical equivalents of -7.37 ± 3.18 D [mean ± standard deviation] who underwent hole ICL implantation and whose targeted refraction was set at slight myopia (-0.61 ± 0.28 D) for both eyes. We assessed the safety, efficacy at near to far distances, predictability, and adverse events of the surgery, during the 6-month observation period. Results. Corrected distance visual acuity did not improve significantly, from -0.17 ± 0.07 preoperatively to -0.19 ± 0.08 logMAR postoperatively (p=0.066, Wilcoxon signed-rank test). Uncorrected distance visual acuity was significantly improved from 1.30 ± 0.24 preoperatively to -0.03 ± 0.20 logMAR postoperatively (p
