Background And Objective:
Study the correlation between pupillary diameter and intraoperative complications in patients with pseudoexfoliation undergoing phacoemulsification.
Material And Methods:
Prospective, observational, and descriptive study. Data were collected from May 2024 to May 2025.
Results:
Preoperative pupillary diameter <5.5 mm post dilation was significantly associated with the development of intraoperative complications (P = .002). Among patients with complications, the median pupil dilation was 4.99 mm, whereas in those without complications the median was 5.94 mm. Most complications occurred during the phacoemulsification phase (6; 66.7%), followed by capsulorhexis (2; 22.2%). Additionally, the presence of zonular weakness was significantly associated with the development of complications (P < .001).
Conclusions:
Preoperative identification of a pupil diameter <5.5 mm post dilation may alert the surgeon to potential intraoperative findings such as zonular weakness and iris instability, which may lead to better surgical planning.
