Some childhood cataracts may only be partial and thus not interfere with vision. These small cataracts usually do not require treatment but should be observed regularly to look for progression. Moderate cataracts may require treatment with glasses or treatment of amblyopia (lazy eye). Larger cataracts which impair vision are treated with surgery. The surgery in children is done under general anesthesia and require an incision in the eye. Depending on the age of the child your doctor will take the decision of whether to implant a lens in the eye or not.
