Abstract Details

Purpose:

To evaluate the experience of using canaloplasty combined with phacoemulsification in patients with open-angle glaucoma complicated by cataract.

Setting:

The S. Fyodorov Eye Microsurgery Federal State Institution Orenburg Branch.

Methods:

The first step was the conjunctival incision in 3 mm from the limbus with the length of 5 mm, sclera was bared. Superficial scleral flap 3,5x3,5mm was separated at 2/3 of the sclera thickness. Deep scleral flap was dissected directly above Schlemm's canal; Schlemm's canal upper wall was dissected. The entrance to Schlemm's canal was expanded by viscoelastic with 27 G cannula and Schlemm's canal catheterization was performed at 360º by microcatheter Glaucolight. After complete circular dilatation of Schlemm's canal polypropylene suture 10/0 was tied to the distal end of the Glaucolight - fibre. Then the catheter was removed. The degree of stitch tension was evaluated by the degree of trabeculae - descemet membrane deflection. The stitches were put to the sclera and conjunctiva. The second step was cataract phacoemulsification with IOL implantation which was traditionally performed at moderate hypotony.

Results:

3 patients were operated according to the described procedure. Moderate hypotension after the first stage of canaloplasty surgery allowed performing without features the second stage - phacoemulsification. In all cases it was possible to achieve stable reduction of the intraocular pressure. In postoperative period complications were not noticed. In combination with phacoemulsification cataract surgery it was possible to achieve a better hypotensive effect and completely avoid the antihypertensive drops. Intraocular pressure was from 12,0 ± 2,0 mmHg - 1 month after the surgery up to 15,6 ± 2,0 mmHg - 3 months later.

Conclusions:

Absence of sharp decrease of the intraocular pressure allows performing a combined surgery with canaloplasty phacoemulsification. Canaloplasty of Schlemm's canal combined with cataract phacoemulsification allows achieving stable hypotensive effect and reducing the risk of postoperative complications. FINANCIAL INTEREST: NONE
