My daughter 2 years of age & prescription +17 in right eye and -3 in left eye. guide me patching schedule.?

I think it's best to: Check with the pediatric ophthalmologist who prescribed the patching & ask for a written schedule. Our pediatric ophthalmologists use eye drops instead of patching.

Doesn't sound right!: Anisometropia or a difference between the prescription of the eye is a serious issue ANS must be treated. I have never heard of an eye +17... That is exceptionally rare if true. I strongly suggest a good reexamination and possibly under anesthesia. You need to be followed strictly by an ophthalmologist and very strongly suggest a pediatric ophthalmologist. Optometry is not adequate here!
