摘要

AIM:To evaluate functional outcome of sutureless scleral tunnel intraocular lens(SSTIOL)in children with crystalline lens subluxation of more than 7 clock hours.METHODS:A prospective interventional study was conducted consisting of 45 eyes of 44 children in age group 6-18 y having>7 clock hours of lens subluxation who underwent lensectomy-vitrectomy followed by SSTIOL implantation.Primary outcome was improvement in best corrected visual acuity(BCVA)and secondary outcomes were assessment of intraocular lens(IOL)tilt using ultrasound biomicroscopy(UBM),mean change in astigmatism at last follow-up of 1 y and associated complications.RESULTS:The mean preoperative and postoperative BCVA was 1.05±0.28 and 0.64±0.45(log MAR)respectively(P=0.001)at last follow-up.The mean astigmatism preoperatively and postoperatively was-4.17±2.69 D and-1.86±1.25 D respectively(P=0.011).Significant IOL tilt(>5 degrees)was present in 5 cases.The mean percentage endothelial loss was 3.65%±1.92%.The most serious complication encountered was retinal detachment seen in 2 cases.CONCLUSION:SSTIOL implantation provides efficient visual rehabilitation in children provided there is stringent case selection.We recommend caution in children having white-to-white distance>12 mm and presence of peripheral retinal degenerations.
