Abstract

OBJECTIVE:

To evaluate the safety and efficacy of primary phacoemulsification and intraocular lens implantation (PPI) for acute angle-closure glaucoma (ACG).

STUDY DESIGN:

Prospective, nonrandomized comparative trial.

PARTICIPANTS AND INTERVENTION:

Forty-three eyes of 43 patients with acute ACG and uncontrolled intraocular pressure (IOP) were treated by PPI. Thirty-two eyes of 32 patients treated by conventional surgical iridectomy (CSI) constituted the control group.

MAIN OUTCOME MEASURES:

Postoperative visual acuity, IOP, number of antiglaucoma medications, complications, and secondary surgical interventions, if any, required for IOP control.

RESULTS:

Glaucoma control was achieved in 31 eyes (72%) in the PPI group and in 11 (35%) in the CSI group (P = 0.01). Mean preoperative IOP was 40.5 +/- 7.6 mmHg (standard deviation) and 39.7 +/- 7.8 mmHg, respectively (P = 0.46). Mean postoperative IOP was 17.8 +/- 3.4 mmHg (PPI group) and 20.1 +/- 4.2 mmHg (CSI group) after a mean follow-up of 10.2 +/- 3.4 months (P = 0.03). Postoperatively, the mean number of ocular hypotensive medications was 0.18 +/- 0.45 (PPI group) and 0.45 +/- 0.62 (CSI group) (P = 0.0001). Relative increase in postoperative best-corrected visual acuity (logarithm of the minimum angle of resolution) was 0.52 +/- 0.29 (PPI group) and 0.19 +/- 0.21 (CSI group), respectively (P = 0.0001). Additional surgery was necessary in 5 eyes (11.5%) in the PPI group and in 20 eyes (63%) in the CSI group (P = 0.01). Intraoperative and postoperative complications were few and manageable.

CONCLUSIONS:

CSI in patients with acute ACG was effective in reducing IOP initially but was associated with multiple surgical reinterventions. Conversely, primary PPI turned out to be safe and effective in reducing IOP and improving visual acuity. These results affirm that lens extraction may be considered the better procedure in uncontrolled ACG when faced with options of CSI or PPI.
