U.S., May 12 -- ClinicalTrials.gov registry received information related to the study (NCT07577635) titled 'Impact of Iridotomy/Iridectomy Size on Postoperative Pupillary Block and Dysphotopsia Following DMEK' on Jan. 26.
Brief Summary: Descemet membrane endothelial keratoplasty (DMEK) is the standard surgical treatment for corneal endothelial disorders. A postoperative pupillary block may occur despite routine preoperative laser iridotomy or intraoperative surgical iridectomy. Insufficient size or incomplete patency of the iridotomy/iridectomy (IT) may contribute to this complication, while excessively large openings may be associated with postoperative dysphotopsia. This prospective observational study investigates the association betwee...
