Phacoemulsification (FACO) and decompensated angle-closure glaucoma
Keywords:
phacoemulsification/surgery, angle-closure glaucomaAbstract
Objective: to study biometric gonioscopic changes, changes of the IOP, visual acuity, endothelial count and complications in eyes operated by phacoemulsification techniques (FACO) after the diagnosis of decompensated narrow-angle glaucoma.
Methods: a prospective, descriptive, non randomized study was conducted in 32 eyes of 21 patients with the diagnosis of decompensated narrow-angle glaucoma, with previous filtering surgery or without it, who were operated on by the FACO technique and implant of folding intraocular lens (IOL), by clear corneal and intracamerular topical anesthesia in the Ophtalmology Service of "Hermanos Ameijeiras" Surgical and Clinical Hospital. The patients were followed-up during the first week and the first, third and sixth months.
Results: the postoperative IOP values descended between 6 and 10 mmHg in relation to the ones found in the preoperative, with a mean of 6 mmHg at the 6 months. In most of the cases, the biometric values of the anterior chamber exceeded the 3 mm and the angles became open (Goldman gonioscopy). The BCVA achieved at the six months was between the 0.6 and 1, 0 with an average of 0.8. The postoperative endothelial cell count was 2 092 with a p = 0,000. Four patients (12.5 %) needed postoperative ocular hypotensive treatment. Only one patient experienced a collapse in the postoperative filtering bleb. The other two complications found were mild corneal edema and transoperative bleeding in some cases (3) that required intraoperative forced dilatation.
Conclusions: FACO surgery with folding intraocular lens implantation is a useful surgical alternative for the control of decompensated narrow-angle glaucoma that preserves or improves patients' visual acuity, with a low percent of complications.
