Sutureless Glueless Technique Versus Interrupted Suturing for Conjunctival Autograft Fixation After Primary Pterygium Excision: Anterior Segment Optical Coherence Tomography (ASOCT) Study

This study aims to compare the clinical and Anterior segment optical coherence tomography (ASOCT) outcomes between sutured and sutureless conjunctival autograft fixation techniques in the management of primary pterygium. A total of 30 patients with bilateral primary pterygia were included. Each patient underwent pterygium excision in both eyes: one eye received graft fixation using interrupted 10-0 nylon sutures, while the fellow eye received sutureless fixation. Allocation of technique between eyes was randomized. All surgeries were performed by the same surgeon, and patients were followed up weekly for one month. Parameters assessed included graft thickness, interface reflectivity, gutter size, conjunctival congestion, donor site healing, and postoperative discomfort using a visual analogue scale. The study evaluates which fixation method provides faster healing, better cosmetic results, and fewer complications such as graft slippage or recession, especially in relation to pterygium size.
