Abstract
This study was aimed to evaluate visual performance at near to far distances in early presbyopic patients undergoing monovision by implantation of an ICL with a central hole (hole ICL). This pilot study comprised thirty-four eyes of 17 early presbyopic patients (age, 40 to 53 years) who underwent hole ICL implantation, and whose targeted refraction was set at emmetropia for the dominant eye, and at slight myopia (−0.5 to −1.0 diopters (D)) for the non-dominant eye. Corrected distance visual acuity was significantly improved, from −0.11 ± 0.07 preoperatively to −0.19 ± 0.09 logMAR postoperatively (p < 0.001, Wilcoxon signed-rank test). Uncorrected distance visual acuity was also significantly improved from 1.43 ± 0.35 preoperatively to −0.04 ± 0.18 logMAR postoperatively (p < 0.001). The mean binocular visual acuity was 0.01 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. All patients had within the normal range of near stereopsis. Neither cataract formation, significant intraocular pressure rise, nor vision-threatening complications occurred. Monovision by hole ICL implantation provided good binocular vision at near to far distances, without developing cataract, suggesting its feasibility as a new surgical presbyopic approach for early presbyopia.
Highlights
Monovision technique is one of viable options for the management of presbyopia where the one eye is corrected for distance vision and the other for near
Our pilot study showed that binocular uncorrected visual acuity at all distances was overall good even in early presbyopic patients, and that no definite complications were found during the observation period, suggesting its feasibility as a surgical correction for eyes with moderate to high ametropia and early presbyopia
We confirmed that monovision by hole ICL implantation was overall good in terms of the safety, efficacy, and predictability for the correction of moderate to high ametropia, which was in line with previous studies on ICL impantation[1,2,3,4,5,6,7]
Summary
Monovision technique is one of viable options for the management of presbyopia where the one eye is corrected for distance vision and the other for near This technique was not usually utilized when performing conventional ICL (without a central hole) implantation, because of the higher rate of cataract formation in these presbyopic subjects[8,9,10]. The aim of the current study is to prospectively evaluate the safety, efficacy, and predictability of monovision by hole ICL implantation for the correction of moderate to high ametropia in early presbyopic subjects, with special attention to binocular visual performance at near to far distances
