Rupture and chemical accumulation in contact lenses with dexamethasone eye drop administration after congenital cataract surgery.

Dexamethasone and BAK do not accumulate in the contact lenses, and a depot effect of any clinical significance is unlikely. Therefore, the number of drops given after surgery should remain the same regardless of whether the child has contact lenses. The ruptured surface may both decrease the child's comfort and increase the risk of microbial adhesion, and so it is recommended that contact lenses should be replaced once a month throughout the course of anti-inflammatory eye drop treatment after surgery for congenital cataract.
