Summary

The aim of the study is to examine surgical and refractive outcomes of glaucoma combined surgery in six months period of follow up

Detailed description

Trabeculectomy and implantation of the Ex-Press device belong to the same group of anti-glaucoma procedures improving subconjunctival outflow. The most frequently performed glaucoma surgery of choice is still trabeculectomy, although the less invasive implantation of the Ex-Press device is also an effective alternative. Despite the wide application of these two techniques, their impact on postoperative refraction is not entirely known. Quite often, in the early postoperative period there is a decrease in visual function, which is short-term, although there are reports that it can last up to a year after surgery. It can be caused by a reduction in IOP, as well as the direct effect of trabeculectomy on corneal topography, and thus on postoperative astigmatism and refractive error. The occurrence of astigmatism after trabeculectomy has been widely documented Combined operations of implanting the ExPress implant with cataract phacoemulsification differ from phacotrabeculectomy in that, they do not require cutting of the sclera, cutting the limbus and using a punch. The purpose of our research was to compare the phacotrabeculectomy and phacoemulsification combined with Express device implantation in terms of incidence of postoperative astigmatism in a prospective randomized study, and to attempt to determine what factors determine its size.
