“Can surgery fix a lazy eye?”

This is a complex question that you ask. It would depend on the nature and cause of your lazy eye. Also in the optometric and ophthalmology world the term "lazy eye" can mean so many different things. I would recommend you reach out to an eye care professional to ask what the technical diagnosis that you are being diagnosed with and reach out to an eye care provider specializing in Strabismus and Amblyopia.

The medical word for lazy eye is amblyopia. That condition is where the vision in one eye does not develop as well as vision in the other eye. This is treated with patching or atropine eye drops. There is no surgery to fix it. However, if you are actually talking about strabismus, where there is a misalignment of the eyes, then surgery can straighten the eyes. Some people get these conditions confused. SO

Depends on the diagnosis. A complete ophthalmologic exam should be performed.
