Abstract

Purpose: To investigate the efficacy of modified Park’s technique in children with strabismus.

Methods: A total of 120 patients were recruited in the Department of Ophthalmology, Anhui Provincial Children's Hospital, Anhui, China between January 2019 and December 2021. The patients were divided into study and control groups comprising 60 patients each. Control group underwent rectus muscle adjustment suture using standard incision, while study group received modified Park’s technique, which involved intermuscular membrane incision and conjunctiva two-layer suture method. Various parameters such as perioperative indicators, tear film function, and patient satisfaction were assessed.

Results: The study group had significantly lower intraoperative blood loss, duration of surgery and length of hospital stay (p < 0.01). Also, it showed significantly higher Schirmer’s time, tear film break-up time (TFBUT) time and significantly lower corneal staining score (p < 0.01). Satisfaction level was significantly higher in the study group compared to control group (p < 0.05). So also was clinical efficacy (91.67 %) compared to control group (83.33 %). Furthermore, study group exhibited significantly lower incidence of complications (5) compared to control group (11; p < 0.05).

Conclusion: Enhanced Park’s technique improves perioperative indicators, tear film function, and satisfaction level; it also produces high efficacy and lower incidence of complications. This suggests that it might be a viable substitute for conventional treatment of children with exotropia. However, long-term follow-up data will be required to establish the superiority of this treatment strategy.
