Espaillat A, Coelho C, Medrano Batista MJ, et al. - Researchers conducted this single-center retrospective study to evaluate predictive factors associated with glares and halos in patients undergoing cataract surgery with PanOptix trifocal IOL implantation. Between 2017 and 2019, 140 eyes from 70 cataract patients were bilaterally implanted with a trifocal PanOptix aspherical diffractive lens and followed-up for six months. All patients were assessed for refraction, corneal topography, and aberrometry pre-and post-operatively. More mild halos were associated with higher corneal coma at 6 months, with no correlation with other degrees of severity. On multivariate regression analyses, the only predictor of photic phenomena was baseline visual acuity, indicating that patients who have improved visual acuity prior to surgery are more challenging after surgery in terms of visual outcomes.
