Abstract

Purpose: To compare refractive and visual outcomes, patient satisfaction, and complication rates among different age categories of patients who underwent refractive lens exchange (RLE).

Methods: A stratified, simple random sample of patients matched on preoperative sphere and cylinder was selected for four age categories: 45-49 years (group A), 50-54 years (group B), 55-59 years (group C), and 60-65 years (group D). Each group contained 320 patients. All patients underwent RLE with a multifocal intraocular lens at least in one eye. Three months postoperative refractive/visual and patient-reported outcomes are presented.

Results: The percentage of patients that achieved binocular uncorrected distance visual acuity 20/20 or better was 91.6% (group A), 93.8% (group B), 91.6% (group C), 88.8% (group D), P=0.16. Binocularly, 80.0% of patients in group A, 84.7% in group B, 78.9% in group C, and 77.8% in group D achieved 20/30 or better uncorrected near visual acuity (P=0.13). The proportion of eyes within 0.50 D of emmetropia was 84.4% in group A, 86.8% in group B, 85.7% in group C, and 85.8% in group D (P=0.67). There was no statistically significant difference in postoperative satisfaction, visual phenomena, dry eye symptoms, distance or near vision activities. Apart from higher rate of iritis in the age group 50-55 years, there was no statistically significant difference in postoperative complication rates.

Conclusion: RLE can be safely performed in younger as well as older presbyopes. No significant difference was found in clinical or patient-reported outcomes.
