Your eyesight is irreplaceable. Many of the normal daily activities we take for granted-working, driving a car, reading all depend on the health of our eyes. Eye disease which goes undetected can lead to unnecessary impairment of sight. It is the goal of your ophthalmologist to protect and maintain your eyesight. While there are other professionals who provide certain elements of eye care, it is only the ophthalmologist who has the unique medical training and experience to provide complete and total eye care.
