Please describe the medical procedure required to "fix" a lazy eye?

Strabismus surgery: "lazy" eye may mean a couple of different things to patients. If the eye is not working well, and eyemd may recommend patching (ie, for kids) to stimulate the brain to use that eye. If the eye is crossed due to amblyopia (classic "lazy" eye), then the crossed eye can be surgically aligned in many patients. Your eyemd can hopefully tell you exactly what you have& the % success in strabismus surgery.

Only in childhood: It depends on what is meant with "lazy eye". In adults reduced vision due to amblyopia unfortunately can not be "fixed". This can only be done in early childhood, usually by patching and glasses. If the eye deviates, surgery can be done at any age.
