Cataract Surgery in Pseudoexfoliation Syndrome Using the Eight-Chop Technique

<b>Objectives:</b> This study aimed to evaluate the safety and efficacy of the eight-chop technique in cataract surgery in patients with pseudoexfoliation (PEX) syndrome and assess the intraoperative parameters, changes in corneal endothelial cells, intraocular pressure (IOP), and intraoperative complications. <b>Methods:</b> This technique was applied in patients with and without PEX syndrome. Preoperative and postoperative assessments were conducted on best-corrected visual acuity, IOP, corneal endothelial cell density (CECD), coefficient of variation, percentage of hexagonal cells, and central corneal thickness. Intraoperative recordings included operative time, phaco time, aspiration time, cumulative dissipated energy (CDE), and fluid of volume used. <b>Results:</b> We analyzed 150 eyes from 150 patients (mean age, 75.5 ± 5.7 years; 59 men, 91 women). In the PEX group, operative time, phaco time, aspiration time, CDE, and volume of fluid used were 6.7 min, 17.4 s, 85.2 s, 6.91 µJ, and 33.4 mL, respectively, demonstrating favorable surgical metrics. On the other hand, in the control group, operative time, phaco time, aspiration time, CDE, and volume of fluid used were 4.5 min, 14.3 s, 64.0 s, 5.83 µJ, and 25.5 mL, respectively. In addition, CECD losses were 3.7% at week 7 and 2.7% at week 19 in the PEX group and 2.7% and 1.6%, respectively, in the control group. Significant decreases were observed at 7 and 19 weeks postoperatively in the PEX and control groups. No eye in the PEX group required a capsular tension ring due to zonular dialysis. <b>Conclusions:</b> The eight-chop technique in cataract surgery demonstrates excellent intraoperative parameters in patients with PEX, is effective against zonular weakness, and does not require the use of a capsular tension ring. This technique will aid in establishing personalized treatment strategies and improve cataract management and treatment.
