Purpose

To evaluate the clinical performance and quality of vision following bilateral implantation of full visual range trifocal or monofocal IOL in patients undergoing cataract surgery.

Setting

Nine clinical sites in Canada

Methods

This prospective, multicenter study included cataract patients who underwent bilateral cataract surgery and implantation of either the full visual range enVista trifocal IOL (N = 110) or enVista monofocal IOL (N = 50). Besides visual and refractive outcomes, a visual symptom questionnaire that explores the frequency, severity, and bothersomeness of 10 different and common visual symptoms, including glare, halos, starbursts, hazy vision, blurred vision, distortion, double vision, fluctuation in vision, difficulty focusing, and difficulty judging distances or depth was used for evaluating patient-reported outcomes at postoperative Days 120-180.

Results

Postoperatively, the trifocal group showed statistical superiority to the monofocal group for mean photopic binocular UIVA (0.08
±0.09 vs. 0.19±0.15 logMAR) and UNVA (0.12±0.10 vs. 0.36±0.13 logMAR). The percentage of patients who were not at all or a little bothered by haloes and starbursts was 88.1% and 93.7%, respectively.  For other dysphotopsia (glare, hazy vision, blurred vision, distortion, double vision, fluctuation in vision, difficulty focusing, and difficulty judging distances or depth), the two groups were comparable with a 3.5% or less difference in the percentage of patients reporting low frequency (no or occasional), milder severity (no or mild), and minimal bothersomeness (not at all or a little bothered).

Conclusions

The full visual range trifocal IOL provided statistically significantly better visual acuity at intermediate and near compared to the monofocal IOL. The frequency, severity, and bothersomeness with most of the visual symptoms were comparable in both groups. Nearly 90% or higher proportion of patients reported that they were not at all to little bothered with these visual symptoms.
