This systematic review evaluated the visual, refractive, and safety outcomes of phakic intraocular lenses (pIOLs) designed for presbyopia correction in presbyopic adults. Six studies involving 354 eyes were analyzed, revealing that contemporary pIOL designs achieved at least 75% of eyes within ±0.50 diopter of target refraction, with 80% to 90% of patients attaining functional spectacle independence.
Key findings
- At least 75% of eyes achieved ±0.50 diopter of target refraction with contemporary pIOLs.
- 80% to 90% of patients attained functional spectacle independence post-implantation.
- Glare and halos were reported but generally mild, with no sight-threatening adverse events.
Why it matters
Presbyopia affects a significant portion of the population, and current correction methods may compromise visual quality. pIOLs offer a potential alternative that preserves the crystalline lens and may enhance patient satisfaction with vision.
What to keep in mind
Evidence is limited by short follow-up, small sample sizes, and potential industry sponsorship bias.
