Outcomes of Phacoemulsification and PCIOL Implantation in Patients with Chronic Angle Closure Glaucoma

To evaluate the outcomes of cataract extraction by phacoemulsification and posterior chamber intraocular lens (PCIOL) implantation in patients with chronic angle closure glaucoma (CACG). Consecutive CACG patients with co-existing visually significant cataracts were included in this noncomparative interventional case series. After obtaining informed consent, clear cornea phaco-emulsification and foldable PCIOL implantation was performed. Patiens were followed for at least six months. Outcome measures included intraocular pressure (IOP), number of glaucoma medications and visual acuity. Twenty-three eyes of 23 patients with CACG including 14 male and 9 female subjects were evaluated. Mean age was 67.9±7.3 (range 55- 80) years. Mean number of glaucoma medications was 1.87±0.81 preoperatively and was reduced to 0.87±1.05 postoperatively (P=0.01). All patients used glaucoma medications before surgery, however 11 patients (47.8%) did not need any glaucoma medications at final follow-up. IOP was decreased from a mean preoperative level of 16.78±3.64 mmHg to 14.08±2.29 mmHg at final follow up (P= 0.008). Mean preoperative visual acuity was 1.01±0.32 logMAR which improved to 0.37±0.43 logMAR at final follow up (P= 0.001). In CACG patients with co-existing cataracts, phacoemulsification and PCIOL implantation can significantly reduce IOP and requirement for glaucoma mediations.
