Purpose
Partial range of field extend intraocular lenses (PRoF-Ex IOL) offer excellent distance and intermediate visual acuity, but limited distance-corrected near visual acuity (DCNVA). However, clinical experience suggests that some patients obtain excellent DCNVA with these lenses. We compared the characteristics of eyes implanted with PRoF-Ex IOL and very good DCNVA to those with standard DCNVA.
Setting
The study was conducted from 2024 to 2025 in OMIQ Research facilities, a private ophthalmology research group in Barcelona, Spain.
Methods
Prospective, transversal, observational study. Patients implanted with a PRoF-Ex IOL (AcrySof® IQ Vivity® [Alcon] or PureSee® [J&J]) were visited 1-3 months after surgery. The following measurements were made: monocular and binocular, distance-corrected and uncorrected far, intermediate and near visual acuities; photopic pupil diameter, aberrations (RMSHOA y Z4-0), corneal asphericity and axial length (Pentacam® AXL Wave, Oculus); and IOL power. Monocular DCNVA was stratified into tertiles; the characteristics of eyes in the first (better DCNVA) were compared with those in the second and third tertiles (standard DCNVA). Data was analyzed using uni and multivariate generalized estimating equation (GEE) models.
Results
We included 100 eyes from 50 patients, 66.0% of whom were female and the mean age was 69.0 (standard deviation [SD] 8.7) years. The mean distance-corrected visual acuity (DCVA) was 0.00 (SD 0.04) logMAR, and the mean DCNVA was 0.37 (SD 0.15). The tertile with the best DCNVA had values between 0.00 and 0.30 logMAR, while the DCNVA in the other two tertiles (standard DCNVA) had values between 0.32 and 0.76 logMAR. The factors associated with a better DCNVA were a younger age (66.4 vs 71.0 years), better DCVA (0.00 vs 0.02 logMAR) and a smaller photopic pupil diameter (2.81 vs 3.04 mm). None of the other variables were associated with DCNVA from a statistically significant standpoint (p>0.05).
Conclusions
The factors associated with a better DCNVA with these PRoF-Ex IOL were younger age, better DCVA and a smaller photopic pupil. Future studies should evaluate if these results are specific of the PRoF-Ex IOL models evaluated here or of the category in general. These results may be useful to tailor the IOL to patient’s expectations and characteristics.
