ABSTRACT
ABSTRACT: Purpose: To compare the incidence of delayed overcorrection after adjustable inferior rectus muscle recession when using polyglactin versus polyester sutures. Methods: Inferior rectus muscle recessions performed over 23 years were reviewed. Patients were separated into two categories: recession using polyester suture versus polyglactin suture. Surgical results were evaluated by student t-test and Fisher exact test. Results: One hundred and twenty patients underwent inferior rectus muscle recession: 64 patients using polyester suture and 56 using polyglactin suture. By the two-month post-operative exam, 5 overcorrections (hyperdeviation 3 PD) had developed in the polyglactin group, but none in the polyester group (p 0.02). At the final follow-up exam, in addition to the five already present in the polyglactin group, only one small overcorrection had occurred in the polyester group, (p 0.096). Conclusion: The use of non-absorbable suture substantially decreases the possibility of delayed overcorrection in adjustable inferior rectus muscle recession surgery.
