Abstract
This study evaluated the backgrounds, preoperative correction methods, refractive targets, and outcomes of patients aged 46-57 years who underwent implantable collamer lens (ICL) surgery. A retrospective review of 60 eyes from 31 patients was conducted, focusing on preoperative correction methods, refractive status, and both targeted and achieved refractive outcomes. Of these, 61.3% of patients were engaged in desk-bound occupations. Although 25.8% of patients exhibited more than 1 diopter (D) of myopic error in at least one eye during routine preoperative correction and no patients had used presbyopic glasses preoperatively, 77.4% of patients hoped to achieve emmetropia in both eyes postoperatively. Postoperative uncorrected distance and near visual acuities (VA) averaged logMAR - 0.07 ± 0.17 and logMAR 0.10 ± 0.45, respectively. The mean postoperative residual refraction was - 0.62 ± 0.66 D, with all eyes except one achieving postoperative refraction within ± 0.5 D of the target. Although some patients reported occasional use of near glasses postoperatively, satisfaction remained high, with 96.8% of patients rating their satisfaction in the top two levels of a 5-point scale. No adverse events were observed. These findings suggest that ICL surgery is a safe and predictable option for patients in this age group, particularly with appropriate preoperative counseling.
