ABSTRACT
Adjustable sutures as a new method used to increase the success rate of strabismus surgery. There is no consensus regarding appropriate time of adjusting suture. In this study we compare the results of adjustable sutures 8 hours versus 24 hours. In a clinical trials study 25 patiens in each group [8 patients with esotropia and 17 patients with exotropia] underwent strabismus surgery and sutures adjusted 8 hours [group 1] and 24 hours [group 2] after surgery. Minimum follow up was 6 months. In exotropias mean preoperative deviation were 39.8 and 35.2 and 6 months after adjustment were 2.3 and 3.4 prism diopter in groups 1 and 2 respectively. There was not statistically significant difference between two groups. In esotropias mean preoperative deviation were 46.2 and 43.1 and 6 months after adjustment were 2.3 and 2.2 prism diopters in groups 1 and 2 respectively. There was not statistically significant difference between two groups. Adjustable suture technique was an effective method in strabismus surgeries. Adjusting sutures at 8 hours and 24 hours after surgery were comparable and surgeon can be full free in adjusting sutures at those period
