Safety of phakic intraocular collamer lens implantation in 95 highly myopic special-needs children.

PURPOSE: To assess the safety of intraocular collamer lens (ICL) implantation in children with high ametropia by reporting rates and case specifics of perioperative and longer-term adverse events (AEs).
.

SETTING

St. Louis Children's Hospital at Washington University Medical Center, St. Louis, Missouri.

DESIGN

Retrospective case series.

METHODS

Clinical data were collated retrospectively for 95 special-needs children (160 eyes) implanted with a Visian ICL over the past 5 years. All surgeries were performed at St Louis Children's Hospital under brief general anesthesia. The mean follow-up period was 2.0 ± 1.4 years (range, 0.5 to 5.2).

RESULTS

The mean age at implantation was 9.3 ± 5.2 years (range, 1.8 to 25) and mean preoperative spherical equivalent refractive error was -11.20 ± 3.90 diopters (range, 4 to 22). 62 children (62/95, 65%) had a neurodevelopmental disorder. 3 eyes (3/160, 2%) reported minor AE, consisting of steroid-response ocular hypertension, which resolved with cessation of topical steroid drops. Endothelial cell loss averaged 8.1% over 2 years, comparable with that reported in ICL-implanted adults. The most common major AE (7 eyes [7/160, 4%]) was postoperative pupillary block, requiring revision of the peripheral iridotomy. 1 child (1 eye [1/160, 0.6%]) with self-injurious behavior required repair of a wound leak. 1 child (1 eye [1/160, 0.6%]) with Down syndrome developed a cataract 2.8 years after ICL surgery, and 1 child (1 eye [1/160, 0.6%]) with severe autism spectrum disorder experienced traumatic retinal detachment 1.2 years after implantation.

CONCLUSIONS

The most common major AE among the cohort with Visian ICL was pupillary block due to closure of the iridotomy. Overall, the AE rate was low in this higher risk, difficult-to-manage population of special-needs children.
