Official Title: Corneal Endothelial Cell Loss After Trabeculectomy Versus Combined Trabeculectomy Phakoemulsification and IOL Implantation
Brief Summary:
Corneal endothelial cells health and pumping function is crucial to permit corneal optical clarity by keeping cornea in relatively dehydrated state. Corneal endothelial damage has been associated with most types of intraocular surgery. Trabeculectomy is the standard glaucoma surgical intervention in management of progressive glaucoma despite of medical therapy which can be performed in combination with Cataract surgery (Phacoemulsification and IOL implantation) in patients with cataract-impaired visual acuity.
In this study, the investigators will investigate and compare the corneal endothelial cells number and health status before and after trabeculectomy vs. combined surgery (at 1 month and 3 months post-op visits) using Specular microscopy which is a non-invasive technique to access the structure and function of the corneal endothelium by permitting visualization of the corneal endothelial mosaic to assess the effect of this surgical intervention on corneal endothelial cells health and number.
