A study assessing the visual outcomes of children who underwent lensectomies for childhood cataract recently reported that glaucoma development or suspicion was a common finding in children after five years, as well as a modest myopic shift.
The prospective study analyzed data of 994 children (1,268 eyes) from the Pediatric Eye Disease Investigator Group clinical research registry (UK, US and Canada). Many participants were lost to follow-up; 66% were seen in the fifth year with varying outcomes (Table 1).
Within five years, the researchers reported glaucoma-related adverse events in 14% of eyes and retinal detachment in 2%. Additional intraocular surgery was required in 33%, most commonly for clearing the visual axis (29%) or to implant a secondary IOL (10%). The researchers reported no unexpected adverse events.
“Although good visual acuity was possible after cataract surgery in children from birth to less than 13 years of age, age-normal vision was uncommon,” the researchers wrote in their paper. In addition to glaucoma development, they noted frequent amblyopia. Though refractive error was “tightly clustered around emmetropia,” they wrote that the shift should be factored into implant power selection.
