Your eye doctor might recommend meeting with an ophthalmologist when your child is affected by conditions that could benefit from surgical care, such as blocked tear ducts or pediatric cataracts.

During an eye exam, we can help you assess your child's eye health and provide recommendations to help you determine whether or not your child could benefit from the care of an ophthalmologist.
