Phacoemulsification using Iris Hook in Patients with Secondary Angle-Closure Glaucoma Associated with Lens Subluxation

ABSTRACT

PURPOSE: To evaluate the effect on the intraocular pressure after the phacoemulsification on the secondary angle-closure glaucoma associated with lens subluxation. METHODS: We reviewed the clinical records of 8 patients (9 eyes) prospectively who's intraocular pressure (IOP) didn't controlled with medication, so received the lens removal by the phacoemulsification. We reviewed their intraocular pressure, visual acuity, and complications before and after the surgery. RESULTS: The patients' mean age was 60.4 +/- 11.9. Initial mean IOP was 41.2 +/- 15.0 mmHg with mean of 1.1 +/- 1.8 medication and mean preoperative IOP was 30.4 +/- 11.2 mmHg with mean of 1.2 +/- 1.1 medication. Postoperative IOP was 16.2 +/- 2.8 mmHg with usage of 0.6 +/- 0.9 medication during the follow-up of 4.6 +/- 1.4 months, and the IOP of 6 eyes (66.7%) were controlled under 21 mmHg without any medication. With anti-glaumatic medication, the IOP of all patients were controlled under 21 mmHg. The best corrected visions were also improved after the surgery in all patients. The complications occurred in 5 eyes (55.6%), temporarily increased IOP in 4 eyes (44.4%), and hyphema in 1 eye (11.1%). CONCLUSIONS: The phacoemulsification in the secondary angle-closure glaucoma with the lens subluxation showed relatively satisfactory results, but thorough follow-up would be needed due to the recurrence of elevated IOP afterward.
