Advantages:

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.

Methods:

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.
