研究组 & 干预措施
Bilateral iridotomy: Superior
Each subject in this single-arm study undergoes bilateral laser peripheral iridotomy surgery. Each participant will undergo superior laser peripheral iridotomy in one eye and temporal laser peripheral iridotomy in the fellow eye.
干预措施: Superior laser peripheral iridotomy (Procedure)
Bilateral iridotomy: Temporal
Each subject in this single-arm study undergoes bilateral laser peripheral iridotomy surgery. Each participant will undergo superior laser peripheral iridotomy in one eye and temporal laser peripheral iridotomy in the fellow eye.
干预措施: Temporal laser peripheral iridotomy (Procedure)
结局指标

时间窗: 30 days post-operative
Change from baseline best corrected visual acuity evaluated in number of letters correctly read on the ETDRS chart
次要结局
- Change in Peli-Robson contrast sensitivity(30 days post-operative)
- Change in CSV-1000 contrast sensitivity(30 days post-operative)
