AIM： To assess the outcomes of posterior chamber implantable collamer lens （ICL） implantation in Chinese pediatric patients with unilateral high myopic amblyopia.METHODS： Eleven eyes of 11 amblyopic patients aged 11.02±3.34y underwent ICL （model V4, Staar Surgical Inc.） implantation to treat unilateral anisometropia were studied. Visual acuity, cycloplegic refraction, contrast sensitivity, stereopsis, intraocular pressure （IOP）, vaulting, corneal endothelial cell count and complications were evaluated. Patients completed follow-up at 3d, 1, 3mo and the last follow-up time （mean 8.18±2.82mo） after surgery.RESULTS： The mean myopic anisometropia was -13.70±3.25 D preoperatively and ＋0.69±2.63 D at 8mo postoperatively. The logMAR corrected distance visual acuity （CDVA） of the amblyopic eye was 1.51±0.72 preoperatively and 0.75±0.40 at 8mo postoperatively. The logMAR CDVA at 3d, 1, 3 and 8mo postoperatively improved by a mean of 0.64, 1.55, 1.82 and 2.64 lines and gained more than 2 lines accounted for 18%, 45%, 45%, 64%, respectively. The contrast sensitivity of 0.5, 1 and 2 cpd in amblyopic eyes was significantly increased after surgery. No patient had near stereopsis recovery. The vaulting at 3 and 8mo was significantly lower than that at 1mo postoperatively. No other intraoperative or postoperative complications were observed, except an acute pupillary block glaucoma happened in a patient at two weeks postoperatively.CONCLUSION： This short-term results indicate that ICL implantation can be a promising alternative therapy for high myopic anisometropic amblyopia in pediatric patients who have failed with conventional treatments and not suitable to corneal refraction surgery.
