AIM: To observe clinical effect of cyclodialysis suture surgery guided by intraoperative three-mirror lens.

METHODS: Ultrasound biomicroscopy(UBM)and three-mirror lens were taken before operations. Three-mirror lens was used to confirm the position and range of the cyclodialysis and to guide the operations. All the 16 patients(16 eyes)received this operation.

RESULTS: All patients were observed for 3-6mo. The best corrected visual acuity was 0.1 to 0.8; intraocular pressure returned to 11-21mmHg; anterior chamber, pupil, fundus changes returned to normal.

CONCLUSION: It is effective and safe to treat cyclodialysis with suture guided by intraoperative three-mirror lens.
