Purpose Our study evaluated safety and efficacy of Verisyse ™ (AMO) phakic anterior chamber intraocular lens (IOL) in the correction of significant myopic (>−9 D) or hyperopic anisometropia (>+6D) in children who are noncompliant to conventional treatment with spectacle correction or contact lenses. Methods 28 children with myopic anisometropia (range −9.0 to −18.0 D, SE) and 7 patients with hyperopic anisometropia (range +6.0 to +9.5 D, SE) underwent unilateral Verisyse phakic IOL implantation under general anesthesia. All patients had chronic difficulties with spectacles due to aniseikonia or with contact lens intolerance. Pre‐ and post‐operative visual acuity, cycloplegic refraction, anterior and posterior segment examination, axial biometry measurements, endothelial cell counts, stereoacuity and aniseikonia examinations were performed in all patients. Target refraction was approximately 0 to −1 D. The mean age was 6.7 years; range 5–14 years. Mean follow‐up was 19.5 months (range, 10–36 months). Results The mean spherical equivalent cyloplegic refraction of myopic eyes changed from −15.2 D preoperatively to −0.73 D postoperatively. The mean hyperopia reduced from +7.65 D preop. to +0.94. 81% of treated eyes were in the range ±1.0 D of emetropia. The mean uncorrected visual acuity improved from 0.012 to 0.35 (logMAR 0.45 ± 0.22), t‐test; p = 0.0014. The mean best spectacles corrected visual acuity (BSCVA) changed from 0.23 (logMAR 0.58 ± 0.15) to 0.62 (log MAR 0.17 ± 0.13), t‐test; p = 0.0238. The mean Safety Index (BSCVA postop/preop) was 2.18. Improvement in stereoacuity was reached in all 35 patients. Conclusions Anterior chamber phakic IOLs may provide a safe and effective alternative in management of highly anisometropic myopic and hyperopic children, who are noncompliant with conventional treatment with spectacles or contact lenses.
