Clinical Trial Summary

Traditional ciliary body photocoagulation treatment uses the photocoagulation of long-wavelength laser to destroy the ciliary body tissue that can produce aqueous humor. Therefore, it is a kind of palliative treatment which has proved efficacy but causes great pain to patients. The "ultrasonic glaucoma treatment instrument" produced by French EYE TECH CARE company is referred to as EyeOP1. It uses high-intensity focused ultrasound technique to make target part of the ciliary coagulative necrosis, reduce the production of aqueous humor and thereby lower the intraocular pressure. EyeOP1 is ergonomic and suitable for the human eye, making the treatment process more accurate, simple and fast.


Clinical Trial Description

1. Efficacy: 1. Main objective: (1)Assess the decrease in postoperative intraocular pressure from baseline and evaluate the final results (the percentage of patients whose conditions have significant improved and the variation of the percentage of median intraocular pressure. (2)Assess the amount of medication after surgery.

2. Secondary goals:(1) Compare median intraocular pressure with baseline at each postoperative follow-up and access the variation of median intraocular pressure from baseline at each postoperative follow-up. (2) Count the number of intraocular pressure lowering drugs at each postoperative follow-up.

b.Safety: Investigate the incidence of all device-related(or procedure-related) adverse events during the study (intraoperative and postoperative follow-up). ;
