Advanced Vision Testing

 
 



Marco Autorefractor/Keratometer:


Our technicians perform this test before you see the eye doctor.
The Autorefractor estimates the prescription of your eyes.

The Autokeratometer measures the curvature of your eyes.

 

Humphrey's Visual Field Analyzer:


This tests your peripheral vision.

Many diseases can unknowingly damage your peripheral vision.

What are some types of field loss?

 
 

Cirrus OCT (Ocular Coherance Tomography):


This test uses a laser scanner to map the anatomical structure of the retina, optic nerve head, and anterior segment.  The test is quick and painless, and no drops are required.

View some examples below
