With the current medical technology, it is not possible to replace the eyes after complete blindness. Therefore, early treatment and advance treatment for the specific causes of eye diseases are needed, and surgical treatment should be performed for the right symptoms. If you wait until you are completely blind, you will not be able to recover your sight with the current technology, but after the development of medicine, it is possible to achieve artificial eye replacement, but in the last 10-20 years, this technology may not be possible, so if you have eye disease now, you should treat it in time and not wait until you are blind.
