Background:

Presbyopia, the age-related loss of near focusing ability, significantly impacts quality of life.
Refractive surgery options are continually being evaluated for efficacy and safety in diverse patient populations.
Refractive lens exchange (RLE) offers a potential solution for correcting presbyopia.

Purpose of the Study:

To evaluate the safety and efficacy of refractive lens exchange (RLE) as a surgical treatment for presbyopia.
To assess postoperative visual outcomes and complication rates associated with RLE in presbyopic individuals.

Main Methods:

Retrospective chart review of patients undergoing RLE at Oregon Eye Institute.
Inclusion criteria encompassed patient selection, preoperative assessment, astigmatism management, and surgical technique.

Analysis included 68 eyes from 36 patients (32 bilateral, 4 unilateral RLE).

Main Results:

All bilateral RLE patients achieved uncorrected binocular visual acuity of 20/40 and J5 or better within 1-3 months postoperatively.
Over 90% of patients attained uncorrected binocular visual acuity of 20/30 and J4.
Approximately 60% of patients achieved uncorrected binocular visual acuity of 20/25 and J3.

Conclusions:

Refractive lens exchange (RLE) is a safe and effective refractive surgery modality for the presbyopic population.
RLE provides significant improvements in uncorrected visual acuity, addressing the challenges of presbyopia.
