Age at surgery, follow-up visual acuity affect stereopsis outcomes in pediatric cataract patients

Age at the time of surgery and visual acuity of the treated eye influence stereopsis outcomes in pediatric patients with unilateral cataracts, according to the Infant Aphakia Treatment Study.
The randomized clinical trial included 114 patients with unilateral cataracts between the ages of 1 month and 7 months; 57 patients received a primary IOL and 57 patients received contact lens correction.
Stereopsis was assessed with Frisby, Randot Preschool and Titmus Fly tests when patients were 4.5 years old.
Median age at the time of surgery was 1.2 months for patients with stereopsis and 2.4 months for patients without stereopsis (
Twenty-eight patients had a positive response to at least one of the stereopsis tests, but there were no significant differences between the IOL group and the contact lens group regarding stereopsis.
“It is apparent that stereopsis can be achieved in patients with monocular infantile cataracts. Our findings provide evidence that earlier surgery and better acuity in the treated eye play a critical role,” the researchers said.
