Spring Loaded Syringe for Active Silicon Oil Extraction

The aim of our study is to compare between two techniques used for active SOR. The outcomes include efficiency and safety.

Patients with silicon filled eyes and prepared for SOR 540 eyes of 505 patients (one eye in 470 patients, and both eyes in 35 patients) were enrolled in the study.

All eyes underwent SOR using 23-Gauge PPV. The eyes were classified according to the surgical technique used for SOR into two groups:- Group A: SOR was performed using SO extraction program built in Optikon vitrectomy device Group B: SOR was performed using modified spring loaded syringe.
