Clinical Characteristics And Postoperative Outcomes Of Posterior Chamber Intraocular Lens Implantation In Patients Aged 46 Years And Above

To assess the backgrounds of patients aged 46 years and above, their refractive targets, and the outcomes following implantable collamer lens (ICL) surgery.

Masayuki Ouchi Eye Clinic, Kyoto, Japan.

A retrospective review was conducted for 60 eyes from 31 patients aged 46–57 (mean age: 49.4) years who underwent ICL surgery, with a focus on preoperative refractions, visual acuity (VA), preoperative correction methods, and status, targeted and achieved refractive outcomes, postoperative refractions and distance and near VA, and patient questionnaires.

Nineteen participants (61.3%) had desk-bound occupations. The average preoperative spherical equivalent was −7.94±3.00 D, with 8 (25.8%) having >1 D of myopic error in at least one eye. Mean postoperative residual refraction was −0.62±0.66 D. While no patients required near glasses preoperatively, 24 (77.4%) aimed for emmetropia postoperatively. Postoperative uncorrected distance and near VAs were logMAR −0.07±0.17 and logMAR 0.10±0.45, respectively. Eleven patients occasionally used near-vision glasses postoperatively. Satisfaction was high, with 96.8% in the top two levels. No adverse events, including cataract, occurred.

ICL surgery in patients aged 46–57 years had high predictability, safety, and satisfaction with uncorrected VA outcomes. Despite the preference for postoperative emmetropia and increased near-glasses usage, dissatisfaction was minimal, suggesting that with proper preoperative counseling, ICL surgery can remain viable for this age group.
