Brief summary

comparing different types of cuclophotocoagulation with cataract extraction to cataract extraction and goniocynechiolysis in cases of chronic angle closure glaucoma

Detailed description

Evaluation of the safety of MP-TSCPC , CW-TSCPC and endoscopic cyclophotocoagulation when combined with phacoemulsification in cases with CACG Comparing the efficacy of the combined procedures in control of the IOP and the success rate versus lens extraction combined with synechiolysis

Interventions

PROCEDUREphaco+MP-TSCPC

The procedure starts with performing the cyclophotocoagulation using the Micropulse P3 device (IQ 810 Laser Systems; Iridex, Mountain View, CA, USA) at 2500 mW with a duration of 90 seconds in each hemisphere at a 31.3% duty cycle under local anesthesia and then performing phacoemulsification and IOL implantation.

PROCEDUREphaco GSL

phacoemulsification will be done and then the angle is visualized by direct goniolens then the synechia are dissected by cohesive viscoelastic.

PROCEDUREphaco+TSCPC

The procedure starts with performing the cyclophotocoagulation using the IRIDEX's G probe device (IRIDEX Corp. Mountain View, CA, USA) at 1500 to2000 mW with a duration of 1500 ms applying about 15 shots in one hemisphere only under local anesthesia and then performing phacoemulsification and IOL implantation.

PROCEDUREphaco+endocyclophotocoagulation

phacoemulsification will be done and endocyclophotocoagulation will be done after cataract extraction
