Abstract Details

Purpose:

To identify changes in intraocular pressure (IOL), parameters of anterior segment of eye and uveoscleral outflow in patients with primary glaucoma after cataract phacoemulsification.

Setting:

V.P. Vykhodtsev Eye Hospital, Omsk State Medical University, Omsk, Russian Federation

Methods:

The study involved 153 patients (153 eyes) with cataract and initial/advanced stages primary open-angle glaucoma, 90 women and 63 men. All patients were divided into three groups. Before and after surgery patients conducted tonometry, electronic tonography with vacuum compression, using the Patient Interface Clip of FEMTEC Laser System, tested for anterior segment analyzer Pentacam (Oculus). The study examined of index Cuveo - coefficient of ease movement uveoscleral outflow, �Ð�šuveo - uveoscleral coefficient - ratio of uveoscleral outflow in generally outflow intraocular fluid. All patients underwent cataract phacoemulsification with posterior intraocular lens (IOL) implantation. The observation period was 6 months.

Results:

Cataract phacoemulsification with IOL implantation decreased IOP. More pronounced hypotensive effect was in patients with glaucoma in an advanced stage of disease and patients not suffering glaucoma. Topographic relations structures anterior segment increasingly changed after operation in patients with advanced-stage glaucoma. The increasing of uveoscleral outflow (Cuveo) after surgery increasingly manifested in patients with initial stage of glaucoma and in patients without glaucoma. The uveoscleral coefficient (�Ð�šuveo) before and after surgery was prevalent in patients with advanced-stage of glaucoma.

Conclusions:

IOP reduction after cataract phacoemulsification in patients with primary glaucoma was by topographical changes of the anterior segment of eye and increasing uveoscleral outflow.
