Clinical Outcomes and Patient Satisfaction with a New Diffractive-Refractive Trifocal Intraocular Lens – A 12 Month Prospective Study

Abstract

Purpose To evaluate the clinical outcomes and patient satisfaction after implantation of Optiflex Trio, a new trifocal intraocular lens (IOL) following cataract surgery. Methods Patients undergoing phacoemulsification for age-related cataracts and who satisfy the eligibility criteria underwent bilateral implantation with Optiflex Trio trifocal IOL. At follow -up visits of 1, 3, 6, and 12 months, binocular uncorrected and corrected distance, intermediate and near visual acuity, reading performance, contrast sensitivity (CS) and patient satisfaction for dysphotopsia and spectacle independence were evaluated using questionnaires. Results A total of 54 eyes from 27 patients with mean age of 66.30±7.48 years were included in the study. At 12 months, 78% (n = 21) patients had binocular cumulative UDVA of 20/20 or better. Post-op SE refraction accuracy was within ±0.50 D for 93% (n = 50) eyes, and refractive cylinder accuracy was within ≤0.50 D in 94% (n = 51) eyes. The mean binocular UNVA was 0.01±0.05 LogMAR, and the mean UIVA at 60 and 80 cm was 0.07±0.06 and 0.03±0.05 LogMAR, respectively, at 12 months. Reading speeds at 40, 60 and 80 cm showed improvement overtime. No patient had complained of severe dysphotopsia, and none of the patients required glasses for any activity. No eye underwent YAG-laser capsulotomy for significant PCO at the end of mean follow-up. Conclusion After 12 months, Optiflex Trio trifocal IOL provided a complete visual restoration with good visual quality outcomes in terms of uncorrected distance, intermediate and near visual acuity. The incidence of dysphotopsia was low, and spectacle independence was high, resulting in good patient satisfaction. Trial Registry CTRI/2019/10/021647 ( www.ctri.nic.in ).

The Impact of Angle Lambda on Patient Satisfaction after Optiflex Trio Trifocal Intraocular Lens Implantation

“…Previous studies have evaluated the performance of trifocal IOLs, and the visual acuity and refractive outcomes of these studies are consistent with the outcomes of the present study [ 13 – 17 ]. Brar et al [ 15 ] examined the refractive outcomes and visual acuity results after implantation of the Optiflex Trio, which is the same IOL as in this study. They examined 54 eyes from 27 patients, and binocular UDVA of 20/20 or better was achieved for 78% of patients.…”
