Abstract Details

Purpose:

To assess an IOP dynamic after phacoemulsification and phaco-emulsification combined with a modified tunnel trabeculopuncture in patients with primary open-angle glaucoma. Four years of follow up.

Setting:

511 patients (567 eyes) with primary open-angle glaucoma were operated in the ophthalmic department Visiobud of hospital Medbud Kiev, Ukraine in period from 2012 to 2015 years.

Methods:

All patients were divided on two groups according to the antiglaucoma operation. The first group of patients (113 eyes) we performed solitary phacoemulsification, the second group (454 eyes) we performed combined phacoemulsification with modified tunnel trabeculopuncture. All patients were operated by one surgeon in general conditions. IOP was measured in all cases with same pneumotonometer before the surgery, every week during the first month after the surgery and then each 3 month during all period of follow up.

Results:

Mean preoperative IOP in patients of first group was 21.8±4.0 mmHg and in patients of second group – 28.5±3.9 mmHg. Elevation of IOP to 27.8 mm Hg in average in the first group of patients and to 34.2 mm Hg in the second group of patients was observed during first month after the surgery. Trough 2 month after the surgery we achieved stabilization of IOP on normal values in both groups without any medical hypotensive treatment. During all follow up period IOP remains stable in both groups.

Conclusions:

All types of these surgery techniques can be operations of choice in patients with primary open-angle glaucoma. Solitary phacoemulsification is effective procedure in patients with early stages of primary open-angle glaucoma, that didn’t get any hypotensive medicines before the surgery and had narrow angle of anterior chamber, and lens more then 4,4 mm. Combined phacoemulsification with modified trabeculopuncture is the best choice in case of long term of hypotensive medical treatment, preoperative IOP more than 25 mm Hg, severe damage on visual field exam and loss of RNFL thickness according to OCT exam.
