What is the primary role of an ophthalmologist?

The primary role of an ophthalmologist is to specialize in eye health and surgery. Ophthalmologists are medical doctors who are trained to diagnose and treat a wide range of eye diseases and conditions, as well as perform surgical procedures related to the eyes. This includes everything from routine eye exams to complex surgeries such as cataract removal or corneal transplants. Their comprehensive training in both medicine and surgery distinguishes them from other eye care professionals and makes them essential for managing serious eye health issues, thus fulfilling a critical need in the healthcare system.

The other options, while related to aspects of eye care, do not capture the full scope of what an ophthalmologist does. Providing general medical care is not specific to eye health and belongs more to primary care physicians. Conducting vision therapy and fitting contact lenses are services offered by optometrists and opticians, respectively, rather than ophthalmologists. Therefore, the specificity of ophthalmology in dealing with medical and surgical aspects of eye health solidifies why it is the correct answer.
