The patients were divided into two groups: the patients in the control group underwent 23-gauge pars plana active SOR surgery with phacoemulsification 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 6 mo 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 6 mo 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±2.3 min and 4.8±1.2 min in the control and TO groups(P=0.008). The total operation time was 28.2±8.5 min and 24.6±6.4 min, 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(2 mo after surgery) and in one eye in the TO group(4 mo after surgery). CONCLUSION: TO is a simple, effective, time-saving, and safe method for SOR combined with phacoemulsification and IOL implantation.展开更多

The results revealed that this combined operation can make most of them get useful visual acuity, although they were often accompanied with several comlicated eye injuries. We think the most important thing is to choose suitable opertion time, the reasonable operation method and take close followup after operation.展开更多
