Dr. Engler and Dr. Sims are very thorough and comprehensive with their examinations. In fact, there are two parts to their eye health evaluation. They will test your vision to determine the strength of correction you will need. Then they will conduct a detailed eye health evaluation including a corneal evaluation and tear analysis which is vital for patients experiencing dry eyes or interested in contact lenses. Dr. Engler and Dr. Sims also check for signs of cataracts, glaucoma, macular degeneration, diabetic retinopathy and other vision-threatening diseases. Many systemic illnesses and conditions like high blood pressure and diabetes can be detected in the eyes before they affect other parts of the body.
