Bilateral Refractive Lens Exchange with a Hydrophobic Trifocal Intraocular Lens

Abstract

Purpose To evaluate the visual and refractive outcomes in patients who underwent bilateral refractive lens exchange (RLE) with the trifocal hydrophobic FineVision HP IOL. Methods This prospective, single-center, non-comparative study enrolled 70 eyes of 35 patients implanted bilaterally with the FineVision HP IOL (Beaver-Visitec International, Inc. USA). Postoperative outcomes at 3 months included manifest refraction, monocular and binocular logMAR uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), distance-corrected intermediate visual acuity (DCIVA, at 60 cm), and distance-corrected near visual acuity (DCNVA, at 40 cm). The binocular defocus curve was also registered. Results 94.29% of eyes showed a spherical equivalent within ±0.50D and all within ±1.00D. 95.71% of eyes showed a refractive cylinder of ≤0.50D and all ≤1.00D. The mean spherical equivalent and refractive cylinder were 0.16 ± 0.27D and −0.18 ± 0.21D, respectively. Mean binocular CDVA, DCIVA and DCNVA were −0.12 ± 0.06, 0.15 ± 0.07 and 0.03 ± 0.05 logMAR, respectively. 88.57% and 100% of patients achieved a cumulative binocular CDVA of ≥20/16 and ≥20/20, respectively. Furthermore, 51.43% and 91.43% patients achieved a cumulative binocular DCIVA of ≥20/25 and ≥20/32, respectively; and 71.43% and 100% of patients achieved a cumulative binocular DCNVA of ≥20/20 and ≥20/25, respectively. The safety and efficacy indexes were 1.07 and 1.01, respectively. The defocus curve showed a peak of maximum visual acuity, better than 20/16, at distance, with a continuous smooth reduction in visual acuity for intermediate distances, followed by a secondary peak close to 20/20 at near. Conclusions The FineVision HP IOL demonstrated favorable short-term refractive accuracy and visual performance in this prospective cohort, although larger comparative studies with longer follow-up are warranted.
