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<0.001).
The mean binocular visual acuity was 0.02 logMAR or better at all distances (5.0, 3.0, 2.0, 1.0, 0.7, 0.5, and 0.3 m).
All eyes were within ± 0.5 D of the targeted correction.
Neither cataract formation, significant intraocular pressure rise, nor other vision-threatening complications occurred in any case during the 6-month observation period.
Conclusions.
Our pilot study showed that intentional undercorrection by hole ICL implantation for early presbyopia was safe with predictable refractive results and provided good binocular vision at near to far distances, without developing cataract, suggesting its viability as a surgical presbyopic treatment for such patients.
