AIM: To observe the effect of modified minimally invasive 23G combined with standard 20G three-channel vitrectomy for silicone oil removal. METHODS: The objects of study were 32 patients with silicone oil eyes hospitalized in Jingliang Eye Hospital from March 2018 to September 2019. Enrolled patients were provided with standard three-channel incision for vitrectomy, with 23G perfusion and lighting as well as 20G suction incision at 10 o'clock. Silicone oil removal was then conducted by using minimally invasive 23G vitrectomy instrument and modified 18G needle. Further examination was performed to observe the best corrected visual acuity(BCVA), intraocular pressure, pain comfort, silicone oil residue, choroidal detachment, retinal detachment 1d, 1wk, 1mo and 3mo after operation. RESULTS: All the 32 patients underwent operation successfully, and there was stable intraocular pressure and no fluctuation during operation. The removal time of silicone oil was about 10-15min, and no complications occurred intraoperatively. Postoperative 3-month follow-up 3 revealed no vitreous hemorrhage, choroidal detachment and retinal reattachment. CONCLUSION: The modified minimally invasive 23G combined with standard 20G three-channel vitrectomy is simple, safe, stable and effective for silicone oil removal.
