Static and dynamic pupillometry changes after uneventful phacoemulsification surgery

Abstract

Purpose: To compare postoperative changes in static and dynamic pupil size after uneventful phacoemulsification surgery. Materials and Methods: 70 eyes of seventy patients (34 women and 36 men), who underwent phacoemulcification surgery were included in the study. Static and dynamic pupillometry measurements were examined and recorded in patients who were diagnosed with cataract and planned for surgery in the preoperative period without using mydriatic drops. Follow up controls were examined on the 1st day, 1st week and 1st month after cataract surgery. Pupillometry measurements were examined again in the examination at the 1st month control. The Aladdin® (Topcon, Tokyo, Japan) system was used for the measurement of pupillometry. Preop and postop first month pupillometry measurements were recorded and compared. Results: The minimum value of dynamic PD was 3.29±0.94 mm before cataract surgery, which decreased to 3±0.86 mm after cataract surgery (p = 0.016). The maximum value of dynamic PD was 4.12±0.84 mm before cataract surgery, which decreased to 3.88±0.73 mm after cataract surgery (p = 0.01). Mesopic PD was 3.75±0.83 mm before cataract surgery, and it decreased to 3.41±0.59 mm after cataract surgery (p < 0.001). Photopic PD was 3.22±0.73 mm before cataract surgery, and it decreased to 2.82±0.63 mm after cataract surgery (p < 0.001). Conclusion: Phacoemulsification surgery changes the static and dynamic PD due to possible changes in ACD, postoperative anterior chamber reaction and topical drops used.
