The first review after strabismus surgery is 1-2 weeks, and the second review can be 2-3 months, but the time is not completely fixed, it depends on the patient’s strabismus or post-operative recovery, and the type of strabismus, and should also consider the patient’s living environment and distance. During the first review, the focus is on wound healing and whether there is infection, and whether the sutures need to be removed. Nowadays, most of the clinical applications are absorbable sutures, which generally do not need to be removed, but a few patients need to adjust the sutures, or some patients have sutures that need to be removed. The second review focuses on checking binocular vision function. The purpose of strabismus surgery is to restore binocular vision function in children, and some children can recover automatically, while some who do not recover well enough should undergo binocular vision training, and whether there is any postoperative maladjustment for adjustment.
