To evaluate refractive outcomes (measured by MRSE) following implantation with a single-piece diffractive trifocal intraocular lens (IOL) using a femtosecond laser, digital registration, and intraoperative aberrometry (IA).
Single surgeon, unmasked, single site. Retrospective study examining 130 eyes of 65 consecutive patients implanted bilaterally with a trifocal IOL (PanOptix: Alcon Vision) in cases involving femtosecond laser, digital registration, and IA (LenSx, Verion, and ORA with VerifEye+). Patients were unmasked to whether they received a non-toric or toric lens in either eye. Patients were implanted with IOL power as recommended by ORA system (targeted for emmetropia OU). Post-op MRSE, post-op residual astigmatism (PRA), monocular UCVA, and binocular UIVA and UNVA, was recorded at 3 months postoperatively.
At 3 months post-operatively, 91.5% of eyes had MRSE of +/- 0.50D. The mean MRSE was 0.0085D (with a SD of 0.3034D). PRA showed: 85.4% of eyes at 0.00D, 90.0% within 0.25D, and 97.7% within 0.50D, with 2.31% > 0.75D. UCVA showed 82.3% of eyes reaching 20/25 or better, 59.2% of eyes at 20/20, and 11.5% of eyes achieving 20/15 line of vision. UIVA showed 99.2% of eyes reaching 20/25 or better, 95.4% of eyes at 20/20, and 67.7% of eyes achieving 20/15 line of vision. UNVA showed 90% of eyes reaching 20/25 or better with 66.2% of eyes achieving 20/20 line of vision. A linear relationship was found between PRA and UCVA (0.4458 correlation).
These results further demonstrate that the combination use of FLACS, digital registration, and IA during trifocal non-toric and toric implantation can provide excellent refractive and visual outcomes for presbyopic correction.
