Hydrophobic Trifocal Toric Intraocular Lens Outcomes in Japanese Eyes After Cataract Surgery.

ABSTRACT

Purpose: To analyze the refractive and visual outcomes following cataract surgery and implantation of a new hydrophobic trifocal toric intraocular lens (IOL) in Japanese eyes with different degrees of corneal astigmatism. Methods: A total of 66 eyes from 39 patients implanted with a FineVision HP Toric IOL (Beaver-Visitec International Inc) were analyzed retrospectively. The main outcome measures considered were refraction, monocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), and distance-corrected intermediate visual acuity (DCIVA) at 80 and 66 cm, uncorrected near visual acuity (UNVA) and distance-corrected near visual acuity (DCNVA) at 40 cm. Eyes were evaluated at three months post-surgery. Results: Sixty-five eyes (98.48%) were within ±0.50D of spherical equivalent, and all were within ±1.00D (mean 0.00±0.21D). Moreover, 63 eyes (95.45%) had ≤0.50D of residual astigmatism, and all had ≤1.00D (mean -0.08±0.23D). Similarly, 58 (87.88%) and 60 eyes (90.91%) had ≥20/20 UDVA and CDVA, respectively, with 65 (98.48%) and 66 eyes (100%) achieving ≥20/25 UDVA and CDVA, respectively. In addition, 28 (42.42%) and 23 eyes (34.85%) had ≥20/25 DCIVA at 80 and 66 cm, respectively, with 49 (74.24%) and 52 eyes (78.79%) achieving ≥20/32 DCIVA at 80 and 66 cm, respectively. Finally, 39 (59.09%) and 40 eyes (60.61%) had ≥20/20 UNVA and DCNVA, respectively, with 58 (87.88%) and 59 eyes (89.39%) achieving ≥20/25 UNVA and DCNVA, respectively. Conclusion: Our study shows that implantation of the new hydrophobic FineVision HP Toric IOL results in accurate refractive outcomes, with good visual acuity at different distances, in Japanese eyes.
