Children with high ametropia and neurobehavioral disorders may have chronic difficulties with spectacle or contact lens wear. We report longer term outcomes of bilateral or unilateral phakic intraocular lens implantation for ametropia > 10 D

Clinical course and outcome data were collated prospectively in a group of 79 children and adolescents (116 eyes; mean age 11.1 yrs, range 1-22 yrs) with neurobehavioral disorders exacerbated by poor compliance with spectacles. Correction was achieved by implantation of an iris-enclaved (Verisyse myopic; Ophtec hyperopic or toric) phakic IOL under general anesthesia. Mean follow-up was 2.4 yrs (range 4 mos - 5 yrs).
Myopia in 93 eyes ranged -10.0 to -22.75 D (mean -15.3 D) and hyperopia in 23 eyes +10.25 to +12.0 (mean +10.8 D). Goal refraction was ~ 0 to +1D. Myopia correction averaged 14.8 D and hyperopia correction 9.5 D. Eighty-four percent of eyes were corrected to within ± 1 D of emmetropia and the remaining 16% to within ± 2 D. Uncorrected visual acuity improved substantially in 97% of eyes (on average 20-fold; from a mean 20/1100 to a mean 20/46; mean Snellen-fraction gain = 0.41). Ocular comorbidities accounted for residual subnormal visual acuity (e.g. amblyopia, nystagmus, albinism, ROP). Visual functions improved (measured by validated survey) in 84%. Five eyes (4%) required IOL re-enclavation after trauma-related dislocation
Phakic IOL implantation is effective for improving visual function in neurobehaviorally-impaired children who have ametropia beyond the range of excimer laser correction.
