Abstract:AIM: To evaluate the efficacy and safety of a modified technique [trocar opening (TO)] for silicone oil removal (SOR) in combination with phacoemulsification and intraocular lens (IOL) implantation. METHODS: A total of 60 eyes of 60 patients with cataract and silicone oil-filled eyes were enrolled in this study. The patients were divided into two groups: the patients in the control group underwent 23-gauge pars plana active SOR surgery with phacoemulsi?cation and IOL implantation, while the patients in the TO group underwent TO methods during surgery. Best corrected visual acuity (BCVA), surgery time, intraocular pressure, and operative complications were observed 6mo after surgery. RESULTS: There was no significant difference between the two groups in terms of age, gender, preoperative, intraocular pressure, or time of silicone oil stay. Prior to surgery, the mean BCVA for the control and TO groups was 1.34±0.44 and 1.36±0.42. At 6mo following surgery, the mean BCVA improved to 0.74±0.36 and 0.77±0.32, respectively (P<0.001). There was no significant difference between the two groups. The mean SOR time was 6.9±2.3min and 4.8±1.2min in the control and TO groups (P=0.008). The total operation time was 28.2±8.5min and 24.6±6.4min, respectively (P=0.035). Posterior capsule rupture occurred in four eyes of control and none of TO group (P<0.01). Late recurrent retinal detachment occurred in one eye in the control group (2mo after surgery) and in one eye in the TO group (4mo after surgery). CONCLUSION: TO is a simple, effective, time-saving, and safe method for SOR combined with phacoemulsification and IOL implantation.
