Pseudoexfoliation Syndrome

This prospective study aims to evaluate the influence of corneal biomechanical properties on surgically induced astigmatism following standard phacoemulsification cataract surgery in patients with pseudoexfoliation syndrome compared with patients without pseudoexfoliation. Corneal hysteresis (CH), corneal resistance factor (CRF) and corneal astigmatism will be measured before surgery and at postoperative follow-up visits. The relationship between changes in corneal biomechanics and surgically induced astigmatism will be analyzed.

Pseudoexfoliation syndrome is associated with alterations in the biomechanical properties of the cornea. This prospective observational cohort study aims to evaluate changes in corneal biomechanical properties after standard phacoemulsification cataract surgery in patients with pseudoexfoliation syndrome compared with patients without pseudoexfoliation syndrome. Corneal hysteresis (CH) and corneal resistance factor (CRF) will be measured using the Ocular Response Analyzer before surgery and at postoperative day 1, day 7, and day 30. The study will enroll patients undergoing routine cataract surgery to compare postoperative changes in CH and CRF between the pseudoexfoliation and control groups.

The purpose of this study is to assess the effect of pseudoexfoliation syndrome on corneal biomechanics, optical clarity of the cornea, and anterior segment structural features.

To study the possible correlation between pupillary diameter before and after dilation with intraocular pressure, lens stability and glaucomatous damage (represented by optic disc changes using cup to disc ratio and OCT changes in retinal nerve fiber layer and ganglion cell complex) in each eye of the same patient with PEX.

The aim of this study is to compare the surgical outcomes of the two IOL implantation methods for eyes with cataract and PEX in a single-center and with highly experienced surgeons. The goal is to acquire relevant information regarding these two IOL implantation techniques, which will help surgeons to decide which approach to choose, ultimately resulting in a benefit for patients with PEX syndrome who require cataract surgery. The main questions are: Is there a difference in lens tilt and decentration between the both methods. Is there a difference in the frequency and amount of capsular phimosis between the both methods.
