Between the ages of one and two, a painted prosthesis that resembles a normal eye is usually fitted. Clear conformers are used before this time. The conformers are not painted because they are changed too frequently. Until about two years of age, a child will progress every few weeks to a larger size. If the child still needs to wear conformers pass the age of two, the conformers can be painted to look like a normal eye. Before the age of 10, the average child will require three to four new painted prostheses. Residual vision (limited sight) is present in children with microphthalmia. The good eye is patched to strengthen vision in the microphthalmic eye. Prosthesis can be constructed to cap the microphthalmic eye and help with cosmetic appearance as well as preserve the remaining sight.
