Toric IOL Outcomes With and Without Advanced Intraoperative Aberrometry
Narrative Responses:
Purpose
Compare refractive results from cataract surgery with toric IOLs with and without intraoperative aberrometry with streaming refractive data.
Methods
One month postoperative results were evaluated from eyes undergoing cataract surgery with toric IOL implantation at a single center. In the conventional method group, the IOL power was determined using preoperative information and the manufacturer’s standard toric calculator; corneal marks were used to ensure placement of the IOL in the correct axis. In the intraoperative aberrometry group, a commercially available intraoperative aberrometry system (ORA with VerifEye) was used to determine sphere and cylinder power and to refine the on-axis positioning of the lens intraoperatively. Post-refractive eyes were excluded.
Results
In the conventional method group (n=21) mean keratometric astigmatism was reduced from 2.08 D ± 0.74 D preoperatively to 0.46 D ± 0.48 D postoperatively, with 67% of eyes within 0.50 D of the predicted spherical equivalent (SE). In the intraoperative aberrometry group (n=10), mean keratometric astigmatism was reduced from 2.25 D ± 0.80 D preoperatively to 0.36 D ± 0.35 D postoperatively, with 80% of eyes within 0.50 D of the predicted SE. Data for 60 eyes (30 in each group) will be presented.
Conclusion
Early results indicate that intraoperative aberrometry with streaming refractive data improves toric IOL outcomes.
