Abstract Details

Purpose:

We assessed the hypotensive effect and long-term efficacy of combined phacoemulsification with modified tunnel trabeculopuncture (MTTP) in patients with open-angle glaucoma during five years of follow up.

Setting:

The 1342 patients (1993 eyes) with primary open-angle glaucoma have been operated in Clinic Visiobood in Kiev, Ukraine in the period from 2012 to 2017 years.

Methods:

Combined phacoemulsification with modified tunnel trabeculopuncture was performed at all patients. The main specialty of this operation is a performing of trabecolopunctures of the internal wall of shlemm's canal laterally of filtrating zone and implanting into the space of shlemm’s canal the rests of capsular bag of the crystal lens as a tube. All patients were operated by one surgeon in general conditions. During five years after operation every three months we examined level of the intraocular pressure and optical nerve condition by tonometry, computer perimetry and OCT of the optic nerve.

Results:

Average IOP in patients before operation was 28,1±0,89mmHg. During 1st month after operation IOP was 26,1±0,32mmHg, then IOP decreased to 14,6±0,38mmHg during three months. From 6 months till 5 years after operation IOP keeps stable in average 16,1±1,22 mmHg during all term of examination. In 86,4% cases: OCT data were stable; light sensitivity became better during three months after operation, then after six months this data returned to it’s preoperative mean’s and stayed stable during all term of examination. In 86,4% we didn’t use any hypotensive drops, except pilocarpinum 1% (21% cases).

Conclusions:

Combined phacoemulsification with modified trabeculopuncture is effective operation technique, which allows to decrease IOP more then 30% and to achieve long-term (six years) stabilising of visual functions in 86,4% patients with open-angle glaucoma.
