Background

The increasing incidence of esotropia, potentially associated with excessive smartphone use, highlights the importance of ensuring the safety of strabismus surgery.

Purpose

This nationwide questionnaire survey, conducted as the Japanese Strabismus Surgery (Japanese Strabismus Surgery) study, aimed to estimate the incidence of severe complications associated with strabismus surgery and to characterize perioperative management practices in Japan.

Methods

All strabismus specialists affiliated with the Japanese Association for Strabismus and Amblyopia.

n = 97 active surgeons
Results

More results

Of 210 specialists, 99 completed the questionnaire (response rate, 47.1%).

After excluding 2 nonsurgical respondents, we analyzed data from 97 active surgeons (mean experience, 28.7 ± 12.2 years) covering 108 623 strabismus surgeries.

More results

For perioperative management, nearly all surgeons (91.8%) used povidone-iodine immediately before surgery, all (100%) prescribed postoperative antibiotics, and most (74.2%) used adhesive drapes.

A large majority (87.6%) conducted the first postoperative follow-up examination on day 1.

Conclusion · 1 of 2

This Japanese Strabismus Surgery study demonstrates that severe complications associated with strabismus surgery are exceedingly rare in Japan.

Conclusion · 2 of 2

Stringent, standardized management protocols, particularly for infection control and early postoperative follow-up, may contribute to this high level of safety.
