Combined VCST With Phacoemulsification Versus Phacoemulsification in Primary Angle Closure Glaucoma

As ab externo metal probe trabeculotomy cannot achieve 360-degree circumferential angle surgery, prolene suture can be used to achieve this without the need for an illuminated microcatheter. In order to combine the advantages of the use of viscoelastic and those of circumferential trabeculotomy, this technique (Visco-Circumferential-Suture- Trabeculotomy "VCST") was previously used successfully in PCG. In the current study , the authors hypothesize that combination of VCST with phacoemulsification in primary angle closure glaucoma patients may have an added affect to phacoemulsification alone in cases with more extent of angle damage and that the injection of a viscoelastic into both ends of the unroofed SC before its cannulation by a polypropylene suture and subsequent circumferential trabeculotomy may facilitate circumferential cannulation of SC and hence the trabeculotomy and increase the success of the technique
