Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Pseudoexfoliation (PEX) syndrome presents challenges in cataract surgery due to potential zonular weakness.
  • Evaluating novel surgical techniques is crucial for optimizing outcomes in complex cases.

Purpose of the Study:

  • To assess the safety and efficacy of the eight-chop technique in cataract surgery for patients with PEX syndrome.
  • To compare intraoperative parameters, corneal endothelial cell changes, intraocular pressure, and complications between PEX and control groups.

Main Methods:

  • The eight-chop technique was applied to patients with and without PEX syndrome.
  • Preoperative and postoperative assessments included visual acuity, intraocular pressure (IOP), and corneal endothelial cell density (CECD).
  • Intraoperative data collected: operative time, phaco time, aspiration time, cumulative dissipated energy (CDE), and fluid volume.

Main Results:

  • The eight-chop technique demonstrated favorable surgical metrics in the PEX group compared to the control group.
  • Corneal endothelial cell density losses were observed postoperatively in both groups, with slightly higher but acceptable losses in the PEX group.
  • No cases in the PEX group required a capsular tension ring due to zonular dialysis.

Conclusions:

  • The eight-chop technique is effective and safe for cataract surgery in patients with PEX syndrome.
  • The technique manages zonular weakness effectively, potentially eliminating the need for additional devices like capsular tension rings.
  • This approach contributes to personalized treatment strategies and improved cataract management.
