Microcornea often presents with a cataract, sometimes in childhood because of syndromic associations and sometimes in adulthood with increasing nuclear sclerosis.
Often, this is a hard brown cataract because of reluctance on the part of both the patient and the surgeon to operate on a high-risk eye. Cataract surgery is difficult in such eyes. Small eye phenotypes such as microphthalmos, nanophthalmos, posterior microphthalmos and cornea plana have their prognosis and management influenced by coexisting ocular anomalies.
Microcornea is associated with a microchamber and a microbag (Figure 1).
