Objective: To evaluate the safety and surgical efficacy of epiphora caused by conjunctivochalasis that includes surgical removal of the excess conjunctiva. Methods: This was a retrospective case series study. From June 2015 to December 2017, 31 patients (31 eyes) who were diagnosed with conjunctivochalasis underwent partial conjunctival resection in the Department of Ophthalmology, Southwest Hospital, Army Military Medical University. All patients had grade III and above conjunctival relaxation. After partial conjunctival resection, the patients were examined for changes in their symptoms and signs of conjunctival prolapse as well as tear break-up time (BUT) and tear meniscus. The changes in BUT were compared before surgery and after surgery at 1 month, 6 months and 12 months, and changes in tear meniscus were compared before surgery and after surgery at 6 months by paired t test. Results: After the operation, the patients' epiphora disappeared. No conjunctival epiphora was observed when the conjunctival suture was removed. There was no recurrence of conjunctivochalasis based on slit lamp examination during the follow-up period of 12 months to 17 months after surgery. Tear break-up time significantly increased at each time point after surgery (P<0.001), and the tear meniscus was higher than it was before surgery(P<0.001). Conclusions: Surgical removal of excess conjunctiva is safe and is an effective way for correcting epiphora caused by conjunctivochalasis. The free conjunctival edges were sutured and the sutures passed through the superficial sclera. This procedure can effectively avoid incision dehiscence and suture-related complications. This surgical method is a worth while clinical procedure.
