A Two-Port Inexpensive and Effective Method for Silicone Oil Removal

Summary

Background:

There are several ways to remove silicone oil (SO) from the vitreous cavity.

Objective:

To describe a simple, safe and inexpensive method of 2-port SO removal.

Method:

Medical charts of 33 patients who underwent SO removal combined with cataract extraction were retrospectively reviewed, from a cohort of 119 patients who had silicone oil removal. The primary outcome was the rate of re-detachment, secondary outcomes included visual acuity (VA) and intraoperative and postoperative complications.

Results:

Mean follow-up time was 27.6 months (0.25–147 ± 33.1), and mean tamponade duration prior to SO removal was 16.77 months (4–51.5 ± 14.6). The re-detachment rate was 3% (one patient). Postoperatively, seven patients (20%) had epiretinal membrane (ERM), eight patients had posterior capsule opacification (24%), and proliferative vitreoretinopathy (PVR) was diagnosed in two patients (6%). Compared to the mean VA (logarithm of the minimum angle of resolution [LogMAR]) at the preoperative examination, the mean VA (LogMAR) improved significantly at the last visit when including all ranges of VA (n=32, LogMAR 1.52 vs. 1.05 P = 0.0002 [Student's t-test] and P = 0.001 [Wilcoxon test]).

Conclusions:

The technique described is fast and simple, keeping the posterior capsule intact in pseudophakic patients, which is advantageous in the event of future re-detachment necessitating SO reinjection. Rates of re-detachment and postoperative ERM and PVR were low. Furthermore, our method does not require the use of a surgical microscope with posterior segment viewing systems, or opening a full disposable vitrectomy set, thus drastically reducing the procedure's cost.
