Abstract Details

Purpose:

The aim of the study was to analyze the procedure of silicone oil cataract removal, taking into account the surgical technique, complications, and determining the optimal treatment.

Setting:

Department of Ophthalmology, Medical University of Gdańsk, Poland

Methods:

This was a cohort study conducted through evaluating the medical files of 121 eyes of 121 patients who underwent cataract surgery in years 2007-2011. Phacoemulsification was performed typically, with bimanual irrigation/aspiration. In patients with secondary glaucoma or damaged posterior capsule, silicone oil was removed from the vitreous chamber and the retina was evaluated intraoperatively. The specifics of silicone oil cataract treatment, surgical technique, and possible complications were analyzed.

Results:

Damage of the posterior capsule during cataract removal occurred in 9 cases (7,4%). In three eyes (2,5%) it was a small hole, while in 6 (5%) a large rupture. In 23 patients (19.0%) an intraocular lens was not implanted mainly as a result of capsule rupture or silicone oil penetration. In 46 cases (38,0%) silicone oil was removed. In 5 eyes (4,1%) additional vitrectomy was required due to retinal redetachment. In 7 patients (5,8%) posterior synechiae were released, in 14 (11,6%) in the final stage of the treatment sterile air was administered into the anterior chamber.

Conclusions:

Silicone oil cataract is not routinely operated and the steps of the procedure may vary. The surgical technique depends on the clinical condition and frequently changing intraoperative conditions. Applying optimal approach the surgery is successful. Preoperatively the symptoms of irydodenesis or focal posterior capsule opacities should be observed. The most common complications of surgery are varying degrees of damage to the posterior capsule and the passage of silicone oil. Special attention to the preservation of the anterior chamber should be paid particularly during cortical clean up procedure.
