Visual acuity, refractive error, and regression outcomes in 169 children with high myopia who were implanted with...

To analyze outcomes in a large cohort of spectacle-aversive children with high myopia who were treated by implantation of the Ophtec-Artisan or Visian phakic intraocular lens (pIOL).

Outcome data were collated retrospectively in 78 children (115 eyes) implanted with the Ophtec-Artisan iris-enclaved anterior chamber pIOL and 91 children (154 eyes) implanted with the Visian ICL (intraocular collamer lens) sulcus pIOL. All children had difficulties with spectacle or contact lens wear. Mean age at surgery was 9.9 years; mean follow-up was 3.9 years (range, 0.6-14.1 years).

A total of 248 of 269 eyes (92%) were corrected to within ± 0.5 D of their target value. Spherical correction averaged 12.3 ± 1.0 D. Refractive spherical regression was -0.04 D/year at last follow-up. Uncorrected distance visual acuity improved from an average logMAR 1.8 to 0.4; corrected distance visual acuity improved an average 0.3 logMAR. Of the treated children, 68% had a gain in binocular fusion. Neurobehavioral and/or visuomotor comorbidities were present in 87% of children. Five eyes (2%) developed retinal detachment an average 6 years after implantation. Nine eyes (3%) implanted with the Ophtec-Artisan pIOL required repositioning after trauma.

Implantation of pIOLs in children is an effective method for correcting high myopia in spectacle noncompliant children. Rates of myopic regression after pIOL surgery are substantially lower than those reported for children treated by excimer laser photorefractive keratectomy (PRK). The prevalence of major complications was relatively low in this high-risk population.
