Clinical characteristics and postoperative outcomes of posterior chamber intraocular lens implantation in patients aged 46 years and above

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.
