Glaucoma is a serious blinding eye disease. The ratio of closed-angle glaucoma to open-angle glaucoma in
China is 3.7: 1. The pathogenesis of primary angle-closure glaucoma is pupil block, and the closure of the angle
of the chamber causes an increase in intraocular pressure. The first choice for the treatment of angle-closure
glaucoma is to remove the pupil block and expand the drainage of aqueous humor to reduce intraocular pressure.
This article aims to study the ultrasound biomicroscopy observation after angle-closure glaucoma intraocular
lens implantation. In this study, 15 females (15 eyes) and 17 males (17 eyes) were selected in the experiment.
They were treated with phacoemulsification aspiration combined with posterior chamber intraocular lens
implantation under surface anesthesia. Changes in depth and anterior chamber angle. Experimental data shows
that the intraocular pressure after preoperative medication is 11-21 mm Hg (1 mm Hg = 0.133 kPa), the average
intraocular pressure is 16.75 mm Hg; postoperative intraocular pressure is 8-17 mm Hg, and the average
intraocular pressure is 11.25 mm Hg; The experimental results showed that the visual acuity of 32 patients was
improved to varying degrees, and the intraocular pressure was controlled within the normal range. There were
27 patients with 84.38%. The visual acuity was greater than 0.5. Through experiments, we can know that
phacoemulsification and intraocular lens implantation is a safe, feasible and effective method for the treatment
of angle-closure glaucoma with cataract.
