Visual Acuity Outcome Comparison Of Two Alcon Trifocal Iols, Clareon® Panoptix® And Acrysof® Iq Panoptix®

To evaluate visual acuity at different distances after intra ocular lens (IOL) implantation of trifocal IOL Clareon® PanOptix® (Alcon model CNWTT0) and trifocal IOL Acrysof® IQ PanOptix® (Alcon model TFNT00) after successful cataract surgery or refractive lens exchange surgery.

This is a single surgeon, single site observational follow-up study in Silmaasema Silmasairaala,Turku, Finland. 

The CNWTT0 was implanted in 62 eyes of 31 consecutive patients. The TFNT00 was implanted in 62 eyes of 31 patients. Toric IOL versions were used when applicable. Barrett lens factor of 1.94 was used. Post-surgery visit was at 1 month. The groups where equal in terms of gender (65%/61% female), age (56y/57y), and implanted IOL power (22.2D/21.9D, right/left, compared to 22.4D/22.2D). The main outcome parameters were LogMAR uncorrected visual acuity at distance (binocular UDVA 6 m), intermediate (binocular UIVA 63 and 100 cm) and near (binocular UCNVA 40 cm). ETDRS type charts with rulers were used.

At 1-month, binocular UDVA was equal, logMar -0.03 with CNWTT0 and logMar -0.04 with TFNT00, p=0.26. UCNVA at 40cm was equal, logMar 0.00 vs 0.00, p=0.39. Also, intermediate visual acuities were equal, UIVA  63cm logMar 0.00 vs -0.01, p=0.18, and UIVA 100cm logMar 0.06 vs 0.05, p=0.28.

Both Alcon trifocals, newer CNWTT0 with Clareon® material and previous TFNT00 gave excellent uncorrected distance visual acuity. Both trifocal IOLs share the same diffractive rings and near and intermediate visual acuities were equally good, as expected. The material differences and lens edge design differences did not affect visual outcomes in this IOL comparison study.
