Refractive and Visual Outcomes Using a Trifocal, Diffractive, Hydrophobic Intraocular Lens in Japanese Eyes

Abstract

Purpose

To report the refractive and visual outcomes after implantation of a trifocal, diffractive, hydrophobic intraocular lens (IOL) in Japanese eyes following cataract surgery.

Methods

A total of 45 eyes implanted with FineVision HP IOLs (Beaver-Visitec International, Inc. USA) were enrolled in this retrospective study. The clinical outcomes assessed after 3-months were refraction and monocular logarithm of the minimum angle of resolution (LogMAR) uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), 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.

Results

97.78% of the eyes were within ±0.50D of spherical equivalent and all of them were within ±1.00D (mean: −0.00±0.22 D, with 75.56% within ±0.13D), while 91.11% of the eyes had ≤0.50D residual astigmatism and all of them had ≤1.00D (mean: −0.08±0.24D, with 88.89% ≤0.25D). UDVA and CDVA showed mean values of −0.05±0.07 logMAR and −0.07±0.06 logMAR, respectively. 86.67% and 95.56% of the eyes had ≥20/20 UDVA and CDVA, respectively, with 100% achieving ≥20/25 for both UDVA and CDVA. At 80 cm, the mean monocular logMAR UIVA and DCIVA were 0.18±0.14 and 0.14±0.14, and at 66 cm the values were 0.20±0.15 and 0.19±0.15, respectively. At 80 cm 20% of the eyes had ≥20/25 DCIVA and 60% had ≥20/32 DCIVA. These values changed to 15.56% and 40% of the eyes at 66 cm. In terms of near vision, the mean monocular logMAR UNVA and DCNVA were 0.04±0.10 and 0.03±0.10, respectively. 53.33% of the eyes had ≥20/20 UNVA and DCNVA, with 86.67% achieving ≥20/25 UNVA and DCNVA.

Conclusion

The FineVision HP trifocal diffractive IOL provided accurate refractive outcomes with good visual acuity at different distances in Japanese eyes.
