Cosmetic Pterygium Surgery: Techniques and Long-Term Outcomes.

Abstract

BackgroundTo demonstrate the long-term results of enhanced cosmetic pterygium surgery with extensive Tenonectomy, adjunctive fibrin-glued amniotic membrane transplantation (AMT), and mitomycin C (MMC).MethodsRetrospective chart review of patients who had pterygium surgery with AMT and MMC between January 2001 to July 2017 and had completed at least 6 months of follow-up. Early and long-term postoperative cosmetic outcomes, recurrence rate, and complications were analyzed. Cosmetic outcomes were evaluated based on patient and surgeon reported outcome measures.ResultsThe study was conducted on a total of 603 eyes of 578 patients (316 males, 262 females) with an average age of 52.9 ± 15.1 years. At post-op day 1, patients reported no discomfort and could not tell which eye had surgery based on patient reported subjective grading scales. Over an average follow-up period of 23.1 ± 35 months (range: 6–216 months), there was one pterygium recurrence (0.2%), eighteen granulomas (2.9%), one self-resolving scleral melt (0.2%), one correctable restricted ocular motility (0.2%), one pupil abnormality (0.2%), one dellen (0.2%) and one correctable upper lid abnormality (0.2%). Planned laser vision correction was used for residual corneal scar in eleven eyes (1.8%) as a staged refractive approach.ConclusionThis study highlights an improved technique of an old concept of pterygium surgery that not only reduces the recurrence but also enhances cosmetic excellence and improves the quality of vision.
