Comparison of 3-month visual outcomes of a spherical and a toric trifocal intraocular lens

Abstract

Purpose: To evaluate visual outcomes and satisfaction after implantation of 2 trifocal intraocular lenses (IOLs): a spherical IOL and a toric IOL.
Setting: IOA Madrid Innova Ocular, Madrid, Spain.
Design: Prospective, controlled clinical trial.
Methods: Patients (>50 years) were implanted bilaterally with either a trifocal spherical hydrophilic IOL (FineVision POD F) if corneal astigmatism was 1.0 diopter (D) or less, or with a trifocal toric hydrophilic IOL (FineVision POD FT) if astigmatism was more than 1.0 D. Outcomes analyzed 3 months after surgery included monocular and binocular visual acuities at distance, near, and intermediate, both uncorrected and corrected. Defocus curves, contrast sensitivity, and patient satisfaction were also assessed.
Results: There was no statistically significant difference between groups in monocular uncorrected distance (UDVA) (P = .38), monocular corrected distance (CDVA) (P = .22), or distance-corrected intermediate (DCIVA) (P = .95) visual acuities; however, the distance-corrected near visual acuity (DCNVA) was slightly better in the spherical IOL group (P = .008). The UDVA was 20/25 or better in 89% of eyes in the spherical IOL group and 93% in the toric IOL group. The DCIVA was 20/32 or better in 92% of eyes in the spherical IOL group and 93% in the toric IOL group at 80 cm (Radner Vissum chart), and 20/32 or better in 100% of eyes in both groups at 63 cm (Colenbrander chart). The DCNVA (Radner chart) was 20/32 or better in 89% of eyes in the spherical IOL group and 90% of eyes in the toric IOL group. There was no difference between the groups in contrast sensitivity, defocus curves, cylinder, or satisfaction results.
Conclusion: Patients had significant improvement in visual acuity and gained functional uncorrected visual acuity across all distances in both groups. Satisfaction was high with both IOLs.
