Anterior Capsule Opacification (ACO) Opacification of the residual peripheral anterior capsule is known as anterior capsule opacification (Figure (Figure2A). GCD2 is usually diagnosed in the teens or early adulthood and often progresses more slowly than GCD1. Patients with GCD2 develop corneal opacity as granular and lattice deposits that increase with age. Combinations of different illumination and visualization techniques may be employed to inspect the cornea, depending on the pathology.
