Clinical description Patients with IEL are found to have dislocation of the lens, which crietallin present at any age, but may be present from birth.

Treatment of the resulting aphakia may be with contact lenses. In more severe cases, the anomaly is generally detected earlier with a greater impact on visual acuity.
