Immediate post-operative adjustable suture strabismus surgery using a target-controlled infusion of propofol-remifentanil

Abstract

Purpose: To determine the outcome of immediate suture adjustment in adjustable suture strabismus surgery using a general anaesthetic technique.

Methods: Adjustable suture strabismus surgery was performed in 69 patients using a target-controlled infusion of propofol-remifentanil. Sutures were adjusted immediately following surgery and patient satisfaction and ocular alignment were assessed at 3 months postoperatively.

Results: Preoperatively, 71% (49/69) of patients were divergent (group 1) and 29% (20/69) were convergent (group 2). Following surgery, the mean deviation in group 1 was 3.5 +/- 13.08 Delta exodeviation for near and 0.8 +/- 10.66 Delta exodeviation for distance. The mean postoperative deviation in group 2 was 2.6 +/- 9.1 Delta esodeviation for near and 2 +/- 9.0 Delta esodeviation for distance. Overall, 80% (45/69) were within 10 Delta of orthotropia.

Conclusions: Single-stage adjustable suture strabismus surgery produces good results and is well suited to day case surgery.
