Although the first surgery is often successful, some patients develop residual or recurrent eye misalignment and require a second operation (reoperation).\n\nThis study aims to identify the clinical and surgical factors that may increase the risk of undercorrection, overcorrection, or recurrence after the first surgery. It also evaluates the outcomes and success rate of repeat surgery in patients with horizontal strabismus.\n\nPatients undergoing reoperation will receive a complete ophthalmological examination before surgery. The surgical plan will be individualized based on previous surgical history and current eye findings. All procedures will be performed under general anesthesia by the same surgeon. Participants will be followed for three months after surgery to assess eye alignment, movement, and possible complications.\n\nThe results of this study may help improve surgical planning and predict which patients are at higher risk of requiring additional surgery in the future.",[66,67,68],"Strabismus","Esotropia","Exotropia",[70,71,72,73,74,75,76,77],"Horizontal strabismus","Strabismus reoperation","Recurrent strabismus","Ocular alignment","Prism diopters","Paediatric strabismus surgery","Orthotropia","Ocular motility","NOT_YET_RECRUITING","2026-03-06",{"date":81,"type":82},"2026-03-09","ACTUAL",{"date":84,"type":60},"2026-03",{"date":86,"type":60},"2027-07",{"name":5,"class":6},1]
