Yes, there is a limit to how much correction you can do to an eye with that method. I have a -8 correction and it seems that it's already too much. Also heavie

Yes, there is a limit to how much correction you can do to an eye with that method. I have a -8 correction and it seems that it's already too much. Also heavier correction gives not as precise results as small corrections : it depends of the cicatrisation of the eye. You might end up having a better vision but still requiring to have glasses. It seems there exists alternatives like putting a lens inside the eyes which gives really good results and is also reversible. The lens is visible if you look closely. I didn't try the method though.
