Purpose
To determine if intraoperative guidance improves astigmatic outcomes for trifocal toric IOL implantation.
Methods
Retrospective study examining 46 eyes of 23 consecutive patients implanted with a trifocal IOL (PanOptix: Alcon Vision) in cases involving IA (ORA System with VerfiEye+). Cylinder power was determined by IA. Postop UDVA and subjective refraction findings to determine Postop Residual Astigmatism (PRA) were collected at 3 months.
Results
Interim results show the following: 93% of eyes had PRA ≤ 0.50D. Cylinder power was changed in 61% of cases based upon IA. Back calculating using the preop cylinder power, 70% of the cases would have had PRA ≤ 0.50D (p=0.002). Mean PRA was 0.08D±0.25 for IA and 0.42D±0.41 for the back calculation (p=0.008). Cumulative post-op monocular UDVA (LogMAR): 63% 0.0 or better, 78% 0.1 or better, 100% 0.18 or better. Mean post-op monocular UDVA: 0.027±0.10.
Conclusion
In this study, the proportion of eyes with PRA ≤0.50D and mean PRA was lower using IA versus the pre-operative planned cylinder power, demonstrating that cylinder power selection is more accurate following IA recommendation.
