Passive removal of 1000cs silicone oil with 23-G transconjunctival system is an easy and cheap method, which also allows additional vitreoretinal, maneuvers after removal.


91 eyes of 91 patients, enrolled in our clinic between January 2008 and April 2011, were studied retrospectively. After placing the 23 G infusion cannula, 23G trockars & cannulas were placed in two steps and waited for passive flow of the silicone oil through the cannula. Preoperative and postoperative visual acuity (VA), intraocular pressures (IOP), postoperative follow-up time, duration of silicone oil removal, need for intraoperative or postoperative suture and postoperative complications were recorded.

Effectiveness / Safety:

Mean postoperative follow-up time of patients was 15,9±6,1 months (2-27 months). 37 patients (40,6%) underwent additional operations as phacoemulsification, membrane peeling, and endolaser during the surgery. Mean duration of silicone oil removal was 7.1 ± 0.53 minutes. Mean preoperative IOP was 16,3 ± 6,6 (8-44 mmHg); postoperative IOP was 10.9±2.2 (4-20 mmHg). There was need for at least one suture to sclerotomy sites in 26 eyes (28,5%). VA increased in 35 patients (38,4%) postoperatively. The incidence of postoperative hypotony (< 5 mmHg) was 1.1%. The leaking sclerotomy sites were sutured next day so that it did not result in postoperative complications.
