Procedure

-Combined Phacoemulsification-Endoscopic Cyclophotocoagulation(Phaco-ECP)
-Phacoemulsification

Two years

Phaco-ECP is a combined operation of the standard cataract operation with the addition of an intraocular laser procedure called endoscopic cyclophotocoagulation to ablate the ciliary processes to reduce aqueous production and achieve further IOP reduction.

Phacoemulsification is a standard cataract operation involving removal of the cataratous lens and insertion of an intraocular lens.

•A diagnosis of PACG.
•Requiring 2 or more IOP-lowering drugs to control IOP, or IOP >21mmHg on maximally tolerable drugs.
•Able and willing to give informed consent, prior to randomization.
•Older than 18 years of age.

•Previous intraocular surgery or cyclophotocoagulation, with the exception of laser peripheral iridotomy and argon laser peripheral iridoplasty.
•Secondary causes of angle closure including iridocorneal-endothelial syndrome, neovascular glaucoma etc.
•Unable to cooperate for reliable visual field and OCT examination.
