PURPOSE: To compare the postoperative complications, visual outcome, and incidence of strabismus in children suffering from traumatic cataract corrected with contact lens or intraocular lens and to follow up the refractive changes in these eyes for an extended period of time.
METHODS: Forty children, 2 to 13 years old at time of surgery for unilateral traumatic cataract, were followed up for 1.5 to 11 years. Seventeen children were corrected with contact lenses and 23 with intraocular lenses. Thirty-two underwent a primary posterior capsulectomy and anterior vitrectomy.
RESULTS: The mean follow-up after surgery was 7.4 years for the children with contact lenses and 6.2 years for those with intraocular lenses. The incidence of secondary surgical interventions was higher among the children corrected with contact lenses. The eight children (five with contact lenses, three with intraocular lenses) who did not undergo primary posterior capsulectomy had Nd:YAG capsulectomy within 1 year after surgery. Fifteen of the 23 children with intraocular lenses (65.2%) achieved a best-corrected visual acuity of 20/40, and 17 children (73.9%) had a final visual acuity of 20/50, but only five of 17 children with contact lenses (35.3%) achieved this level of visual acuity.
CONCLUSIONS: Correction of unilateral aphakia by intraocular lens in children after traumatic cataracts results in better final visual acuities and binocularity with a smaller incidence of strabismus than when correction is carried out by contact lens. Intraocular lens implantation should be considered the primary aphakic correction in children with traumatic cataract.
