Abstract
PURPOSE: To evaluate the outcomes of combined microincision phacoemulsification with sutureless transpupillary silicone oil (SO) removal using an irrigation probe of bimanual irrigation/aspiration. METHODS: We conducted a single-center retrospective study, including patients who had undergone phacoemulsification with transpupillary removal of SO, which had been used for intraocular tamponade after a previous pars plana vitrectomy. Outcome measures were corrected distance visual acuity (CDVA), refractive error, intraocular pressure (IOP), and endothelial cell count (ECC) evaluated preoperatively and postoperatively at 3-month follow-up. Any intraoperative or postoperative complications, duration of surgery, and final retinal status at 3 months were also noted. RESULTS: Seventy-four eyes (74 patients) were analyzed. The mean interval between SO placement and cataract surgery was 4.73 months (standard deviation [SD]: 1.02). CDVA improved in 66 (89.2%) eyes and remained the same in 8 (10.8%) eyes (P < 0.001). The mean postoperative spherical equivalent was -0.96D (SD: 0.75) at 3 months (P < 0.001). There was a significant drop in IOP from 15.08 mmHg (SD: 2.67) preoperatively to 11.64 mmHg (SD: 2.02) postoperatively (P < 0.001). The average ECC loss was only 5.7% at 3 months postoperatively. The mean surgical duration was 17.20 min (SD: 7.02). One patient had retinal redetachment and required resurgery. At 3 months, the retina was attached in all patients. CONCLUSION: Combined microincision phacoemulsification with transpupillary passive SO removal using irrigation probe of bimanual irrigation/aspiration is a safe, effective, and less invasive technique that offers the main advantage of reduced surgical trauma, and should be reserved for patients with a stable retina, not requiring additional surgical intervention.
