Abstract

Adjustable strabismus surgery has been done in adult, young adult, and cooperative children and that decrease the rates of overcorrection or undercorrection occurred at immediate and long-term follow up of strabismus surgery. We reviewed the postoperative alignment, drift, and amount of adjustment in 47 patients between 13 and 67 years. We analyzed results for 35 exotropia and 12 esotropia surgeries. All patients underwent a minimum of 8 weeks follow up. The procedure was done by same operator, adjustment was taken at the day afternoon or next day morning. The evaluation of success based on distanct deviation was orthophoric and less than 10 prism diopters. The success rates were 85.71% in exotropia and 91.67% in esotropia. The mean postoperative drift in prism diopters from the alignment immediately after adjustment, or after the surgery if no adjustment was needed, for each group as measured during the most recent follow up was 4.26 for exotropia and 7.5 for esotropia.
