Abstract Details

Purpose:

The aim of this study is to evaluate effectiveness and safety of combined phacoemulsification cataract surgery with intraocular lens implantation and iStent by Glaukos implantation into the Schlemm's canal for patients with open-angle glaucoma and cataract.

Setting:

In 2017 and 2018, 82 treatments were performed at the University Clinical Center Professor K. Gibinski of the Medical University of Silesia, Katowice, and at the Okulus Plus Center of Ophthalmology and Optometry, Bielsko-Biała.

Methods:

The procedures were performed in 58 patients, 38 women and 20 men, 57-85 years. Before the surgery, eye diagnostics were performed and prophylaxis was recommended to reduce the risk of post-operative complications. The procedure was performed using the phacoemulsification method and implantation of a intraocular lens, and implantation of iStent into Schlemm's canal in the inferior nasal quadrant. The variables recorded before surgery and  at 3 months (82 eyes), 6 months (82 eyes), 9 months (80 eyes), 12 months (74 eyes) and 18 months (24 eyes) of follow-up were: intraocular pressure (IOP), the amount of anti-glaucoma medications and postoperative complications.

Results:

After 3 months of observation a reduction of IOP was achieved by 3,58 units, after 6 months by 3,84, after 9 months by 3,62, after 12 months by 3,18 and after 18 months by 3,84 units in comparison to the IOP before surgery. The required number of IOP-lowering medications has been reduced by 1,64  after 3 months, by 1,68  after 6 months, by 1,68  after 9 months, by 1,41  after 12 months and by 1,33 units after 18 months. The most common side effects were: subconjunctival hemorrhages, hyphema,  temporary IOP increase after surgery and foreign body sensation.

Conclusions:

The combined treatment of iStent implantation and phacoemulsification with intraocular lens is an effective and safe procedure to treat coexistent open-angle glaucoma and cataract. During observation time, most patients experienced a significant reduction of IOP. The treatment reduces the required amount of IOP-lowering medications or eliminates them completely.
