Abstract:
This study aimed to assess retinal alterations following membrane peeling procedures using novel ILM Forceps with laser ablated surface with the help of intraoperative optical coherence tomography (iOCT). A post-hoc analysis was performed to evaluate iOCT findings in eyes that underwent membrane peeling procedures with the novel ILM Forceps. Pre-peel and post-peel iOCT videos and images were evaluated for each eye to assess for post-peel anatomic alterations. Surgical video/iOCT scan correlation was conducted to evaluate the etiology of anatomic alterations. Thirty-two eyes were included in the analysis. Three eyes (9%) had focal full thickness retinal elevations identified on iOCT following tissue-instrument interaction with the ILM Forceps. Two eyes (6%) had focal inner retinal elevations and one eye (3%) had a full-thickness retinal elevation that were not related to direct tissue-instrument interaction but rather indirect peeling forces. iOCT-identified architectural alterations related to direct-tissue instrument interaction were relatively infrequent (< 10%) with similar frequency to previously reported alterations with other surgical instruments.
