Stereopsis results at 4.5 years of age in the infant aphakia treatment study.

ABSTRACT:

Purpose

To determine whether stereopsis of infants treated for monocular cataracts varies with the type of optical correction used.

Design

Randomized prospective clinical trial.

Methods

The Infant Aphakia Treatment Study randomized 114 patients with unilateral cataracts at age 1-7 months to either primary intraocular lens (IOL) or contact lens correction. At 4.5 years of age a masked examiner assessed stereopsis on these patients using 3 different tests: (1) Frisby; (2) Randot Preschool; and (3) Titmus Fly.

Results

Twenty-eight patients (25%) had a positive response to at least 1 of the stereopsis tests. There was no statistically significant difference in stereopsis between the 2 treatment groups: Frisby (contact lens, 6 [11%]; IOL, 7 [13%]; P = .99), Randot (
