Purpose The aim of this study was to investigate the ultrastructure of corneal incisions after phacoemulsification by anterior segment optical coherence tomography (AS-OCT). Patients and methods This is a prospective interventional study of 50 eyes of 50 patients with senile cataract attending the Outpatient Clinic of the Ophthalmology Department, Qena University Hospital, Qena, Egypt, for whom clear corneal-incision phacoemulsification was performed from July 2020 to July 2021. The patients had preoperative and postoperative AS-OCT, and were followed up at 1 week, 2 weeks, 1 month, and 3 months, postoperatively. The four AS-OCT features that were studied were corneal thickness at the site of the main incision, epithelial and endothelial changes at the wound, and Descemet’s membrane detachment. Results The mean age of the patients was 62.16±7.71 years. The mean corneal thickness was 768.06±102.03, 883.24±96.59, 841.98±100.70, 797.68±98.12, and 782.26±101.66 μm preoperatively, at 1 week, 2 weeks, 1 month, and 3 months postoperatively, respectively (P<0.001). Descemet’s membrane detachment was observed in nine (18%) and seven (14%) patients at 1 and 2 weeks postoperatively, respectively. Epithelial gaping was observed in five (10%) patients at 1 week and in two (4%) patients at 2 weeks. It was not observed after 1 month, postoperatively. Endothelial gaping was observed in 36 (72%) patients at 1 week, in 30 (60%) patients at 2 weeks, and in four (8%) patients at 1 month, and was not present after 3 months. Conclusion AS-OCT is an excellent tool to assess the integrity and structure of the corneal wound after phacoemulsification sensitively and quantitatively. So, it could play an important role in the early detection and management of endophthalmitis.
