Glaucoma Clinical Trial
Official title:
Surgical and Refractive Outcomes of Combined Phaco-ExPress Versus Phacotrabeculectomy - 6 Months Results.
The aim of the study is to examine surgical and refractive outcomes of glaucoma combined surgery in six months period of follow up
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.
