| Summary: | Abstract Photic phenomena are more pronounced in presbyopia-corrected than in monofocal intraocular lens (IOL), causing dissatisfaction after cataract surgery. Photic Phenomena Test (PPT) quantifies photic phenomena in eyes with two types of presbyopia-corrected IOL. We examined the relationship between preoperative eye shape and pupil diameter. We included patients with PanOptix IOLs (PanOptix group, n = 38; 65.7 ± 9.2 years old) and Synergy IOLs (Synergy group, n = 39; 61.9 ± 9.6 years old), who underwent the PPT between 1 and 3 months after cataract surgery, from January 2021 to April 2023. The relationships between age, sex, pupil diameter, and higher-order corneal aberrations were examined and mean values for PPT measurements were compared between the groups. There was no difference in glare between the two groups. The halo was larger and thicker, and the starburst was larger and stronger in the Synergy group (P < 0.01). Postoperative halo brightness was positively correlated with the corneal coma aberration in the PanOptix group (P < 0.05). The Synergy group showed a positive correlation between the size and brightness of the postoperative halo and starburst and pupil diameter (P < 0.01). PPT, thus, revealed risk factors in eyes with two types of presbyopia-corrected IOL, which can be examined before cataract surgery to provide critical information for IOL selection. |
