PURPOSE: To report the initial experience with a new presbyopic phakic intraocular lens (pIOL) in the correction of high myopia and presbyopia.
SETTING: Gemini Eye Clinic, Zlin, Czech Republic.
DESIGN: Prospective cohort study.
METHODS: Presbyopic eyes with moderate to high myopia were implanted with a presbyopic posterior chamber pIOL (IPCL). The visual acuities at near and distance, endothelial cell density, and ocular condition were examined 1 week, 3 months, 1 year and 2 years postoperatively.
RESULTS: The mean uncorrected distance visual acuity improved significantly from 1.25 logarithm of the minimum angle of resolution (logMAR) (1.15 to 1.35 95% confidence interval [CI]) to 0.11 logMAR (95% CI, 0.03 to 0.17) (P < .0001). No eye lost 1 or more lines of corrected distance visual acuity. The mean distance refraction improved significantly from -6.9 diopters (D) (range -8.6 to -5.3 D) preoperatively to -0.35 D (range -0.55 to -0.15 D, P < .0001) with less than -0.5 D residual refraction in 11 of 17 eyes. Fifteen of 17 eyes had improved uncorrected near visual acuity to J1 (Jaeger chart) at the 2-year follow-up. The near addition at the 2-year follow-up decreased from preoperatively +1.26 D (range 0.19 to 2.34 D) to +0.39 D (range 0.18 to 0.60 D). The mean endothelial cell density was reduced from 2552 cells/mm (range 2421 to 2682 cells/mm) to 2299 cells/mm (range 2108 to 2490 cells/mm) after 2 years. All patients were subjectively satisfied with the outcomes.
CONCLUSIONS: The new pIOL provided good visual outcomes in near and far distances in an initial case series of patients.
