摘　　要：AIM:To describe a novel suture approach for transscleral fixation of C-loop intraocular lenses(IOL)and to compare the surgical outcomes with the four-haptics posterior chamber(PC)-IOL technique.METHODS:We retrospectively analyzed 16 eyes of 16 patients who underwent transscleral fixation of C-loop PCIOLs using a flapless one-knot suture technique,which were followed up for longer than 17mo.In this technique,the capsulorless IOL was suspended using a single suture for transscleral fixation of four feet.Then we compared its surgical outcomes and complications with the four-haptics PC-IOLs using the Student's t test and Chi-square test.RESULTS:Sixteen patients of 16 eyes with a mean age of 58.3±10.1y(42-76y)who received transscleral C-loop IOL implantation due to trauma,vitrectomy,or cataract surgery with inadequate capsule support showed improved visual acuity.The difference was not significant between two IOLs except the surgery time(P>0.05).The mean operation times of C-loop IOL surgery was 24.1±1.83min and 31.3±4.47min of the four-haptics PC-IOL method(P<0.0001).In the C-loop IOLs group,there was statistical difference between the preoperative and the postoperative UCVA(log MAR,1.20±0.50 vs 0.57±0.32,P=0.0003).There was no statistical difference between the preoperative and the postoperative BCVA(log MAR,0.66±0.46 vs 0.40±0.23,P=0.056).However,there was no statistically significant difference in postoperative UCVA and BCVA between the two IOLs(P>0.05).We did not detect any optic capture,IOL decentration or dislocation,suture exposed,or cystoid macular edema in patients underwent C-loop IOLs surgery.CONCLUSION:The novel flapless one-knot suture technique for transscleral fixation of C-loop IOL is a simple,reliable,and stable technique.
