Comparison of Phaco Energy and Complications for Conventional Phacoemulsification and 25-gauge Phacovitrectomy Surgery

Abstract

Aim:To compare cumulative dissipated energy (CED), intraoperative and postoperative complications in eyes underwent conventional phacoemulsification and 25-Gauge phacovitrectomy surgery. Study Design: Retrospective, comparative case series in ophthalmology clinic of Ulucanlar Eye Education and Research Hospital. Methodology: A total of 140 eyes underwent conventional phacoemulsification and 25-Gauge phacovitrectomy surgeries were evaluated. CDE intraoperative, early and late postoperative surgical outcomes were compared. Results: No one had any intraoperative complication in either group. But the mean CDE was statistically significantly higher in combine group (15.07±8.04) than that in phaco group (11.60±7.98). Even these difference postoperative clinical outcomes were not statistically significant in each group. Conclusion: The single session combined phacovitrectomy surgery is safe and effective technique in cases that presents with both cataract and retinal disease.

Cumulative dissipated energy in eyes with and without corneal opacity

“…Ultrasonic energy delivered into the eye during phacoemulsification surgery is presented as CDE in the Centurion system. CDE represents the efficacy of the phacoemulsification procedure, and the delivery of minimum ultrasonic energy is desirable [ 9 ]. According to the results of this study, required CDE is higher in eyes with corneal opacity when compared with eyes with clear cornea.…”

“…On torsional mode, frequency of movements in phaco tip is 32 kHz and this is 80% of the frequency of movements delivered with conventional mode. In addition, torsional mode provides nucleus emulsification with rotary oscillations, while conventional mode provides only forward and backward oscillations of the phaco tip [ 9 ]. Fakhry et al [ 14 ] reported torsional mode, which provides lower ultrasound energy and more effective phacoemulsification when compared with the conventional mode.…”
