Abstract

Purpose: To compare visual outcomes of two newly developed monofocal intraocular lenses (IOLs) (I-Stream H and CT Lucia 211P) implanted in patients undergoing surgery for senile cataract.

Methods: This prospective, comparative, single-center, randomized study included 94 eyes of 94 patients undergoing cataract surgery. Patients were randomized to receive the implantation of I-Stream H IOL (Group 1) or CT Lucia 211P IOL (Group 2). Each patient underwent a complete ocular examination before (V0), 1 month (V1), 3 months (V2) and 6 months (V3) after surgery, including visual acuity testing, objective refraction, slit-lamp biomicroscopy, contrast sensitivity testing and visual function index questionnaire (VF-14).

Results: After surgery, a significant increase of best-corrected visual acuity (BCVA), CS and VF-14 and a significant decrease of SE were detected in both groups at each time point compared to baseline (always p<0.01). No significant differences in the postoperative increase of BCVA (p=0.12), CS (p=0.21) and VF-14 (p=0.31) and decrease of SE (p=0.08) were detected comparing patients from Group 1 and Group 2 at V3. Mean and median prediction error, as well as absolute prediction error values, did not significantly differ between the two groups (p>0.05). Eyes with an actual refraction within 0.25, 0.50 and 1 D were 53.1%, 85.1% and 100% for Group 1 and 55.3%, 87.2% and 100% for Group 2 (p>0.05).

Conclusion: I-Stream H and CT Lucia 211P allowed a satisfied recovery of visual function after senile cataract surgery; both IOLs were shown to have similar outcomes of visual performance.
