The significance of removing the anterior hyaloid membrane and lens capsule in the course of combined surgery in proliferative diabetic retinopathy

摘要

Due to the specificity of complications and to peculiarities of the surgical approach the principles of cataract surgery have been changing, when combined with transciliary vitrectomy. The postoperative complications in surgery for proliferative diabetic retinopathy (PDR) are often related with development of proliferative processes in the anterior eye segment. Therefore, a scope and a type of surgical manipulations in the anterior segment affect, to a great extent, the stability of the obtained result. IOL implantation is indicated for a limited category of patients with PDR. The feasibility of preserving the anatomic separation of the eye into the anterior and posterior segments by the anterior hyaloid membrane and by the posterior lens capsule is decisive in combined PDR surgery. In combined surgeries for PDR, transciliary lensectomy can be a method of choice for patients, who do not need IOL implantation.
