Visual And Refractive Outcomes Of A New Hydrophobic Trifocal Toric Intraocular Lens

To evaluate the visual outcomes and efficacy of astigmatism correction using a new hydrophobic trifocal toric intraocular lens (IOL).

Centre for Sight - ambulatory surgical centres

This retrospective study involved 62 consecutive eyes implanted with the FineVision HP Toric IOL (PhysIOL s.a., Liège, Belgium, part of Beaver-Visitec International, Inc. [BVI], Waltham, USA). The visual and refractive outcomes were assessed preoperatively and 6 weeks after the surgery. Specifically, monocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA) at 80 and 60 cm and uncorrected near visual acuity at (UNVA) at 40cm were evaluated. The rotational stability of the lens was also assessed.

98.39% the eyes were within ±1.00 D and 88.71% of the eyes were within ±0.50 D of spherical equivalent, with a mean value of 0.09±0.39 D. 82.26%. and 98.39% of the eyes had a UDVA of ≥20/20 and ≥20/25, respectively, and CDVA 95.16% and 100%, respectively. The mean UDVA and CDVA were 0.01±0.06 and -0.01±0.04 logMAR, respectively. Greater than or equal to unaided 20/20 vision was achieved at 40cm in 67.74%, UIVA at 60cm in 67.74% and 80.65% at 80cm. Those achieving ≥20/25 were 90.32% (40cm) 95.16% (60cm), and 100% (80cm). Postoperative mean values were 0.04±0.07, 0.03±0.07, and 0.00±0.07 logMAR for UCNVA, UIVA at 60 cm, and UIVA at 80 cm, respectively. The mean rotation of the IOL was 5.8 degrees.

This hydrophobic trifocal toric IOL provides good refractive outcomes with excellent visual acuity across multiple distances providing a full range of focus.
