Novel Fixable Instruments Used in Strabismus Surgery.

Abstract

Purpose: To introduce the application of novel fixable instruments in strabismus surgery without surgical assistants.

Methods: Patients with strabismus requiring surgical treatment were recruited. Under general anesthesia all patients underwent surgery with the three novel kinds of fixable instruments without assistants. The operation time of each muscle was recorded separately.

Results: A total of 30 patients were enrolled in this study. There were 34 lateral rectus muscles, 22 medial rectus muscles, 2 superior rectus muscles, 2 inferior rectus muscles, and 14 inferior oblique muscles. The amount of recession and resection of the lateral rectus muscle was 6 to 11 and 4 to 6 mm, respectively, and the operation time of each muscle was between 8 and 12 minutes (mean ± standard deviation: 9.88 ± 1.59 minutes). The amount of recession and resection of the medial rectus muscle was 5 to 6.5 and 4 to 6 mm, respectively, and the operation time of each muscle was 7 to 14 minutes (mean ± standard deviation: 10.59 ± 2.38 minutes). Two superior rectus muscles were recessed 7 and 9 mm and the operation time was 8 and 10 minutes, respectively. Two inferior rectus muscles were recessed 4 and 5 mm and the operation time was 7 and 9 minutes, respectively. In addition, the operation time of each oblique muscle was 6 to 10 minutes (mean ± standard deviation: 8.57 ± 1.40 minutes). All patients recovered ocular alignment with no adverse reaction in eyes on the first day after surgery.

Conclusions: With the assistance of the novel fixable instruments, the surgeon can easily perform routine strabismus surgeries even without surgical assistants. [J Pediatr Ophthalmol Strabismus. 20XX;X(X):XX-XX.].
