Exam Technology

A comprehensive vision and eye health exam at Memorial Eye includes many advanced diagnostic procedures. Here are some of the tests you may experience while in our offices:

OPTOS Optomap Retinal Exam
A fast and painless way to obtain a thorough evaluation of the retina, without the side effects of dilation. In addition to giving the doctor a detailed view of the retina, the Optomap exam provides an imaging record, which allows us to track the health of your retina from year to year.

Non-Contact Tonometry
Used to determine the internal pressure of your eye, and commonly referred to as the “air puff test”, this instrument measures your eye’s resistance to a small burst of air and uses that data to calculate your intraocular pressure. Elevated pressure, which is neither painful nor uncomfortable, can be indicative of glaucoma.

Frequency Doubling Technology Perimetry
A visual field examination is an important procedure in the diagnosis of glaucoma and various ocular and neurologic diseases. Frequency Doubling Technology Perimeters are used to detect defects in a person’s visual field, particularly defects due to damage caused by early glaucoma.

Corneal Topography Mapping
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea. Since the cornea is normally responsible for some 70% of the eye’s refractive power, its topography is very helpful in determining the quality of vision. The procedure takes just minutes and is completely painless.

Slit Lamp Examination
The slit lamp provides a highly magnified view of the structure of your eye, which allows for a thorough evaluation of the front and back of your eyes, including the cornea, conjunctiva, iris, lens, and retina.


Visioffice Vision System
Cutting edge technology used to measure the location of the pupils, the natural tilt of the head, how the eyes move and other dynamic data, which allows us to fully customize eyeglass lenses and frames to a person’s unique visual behavior.

Refraction technology that measures the way an image is focused on the retina, where vision processing takes place. This procedure gives the doctor a good tool in determining your prescription.

A method of determining focusing errors of the eye in which light is shined through the pupil and the reflected beam is measured. Based on the way the light reflects, the doctor can obtain a good approximation of your prescription.

Phoropter Refraction 
The primary test the doctor uses to obtain your exact prescription. The phoropter, which contains many different lens powers, is placed in front of you. Then by viewing a screen of letters, you and the doctor work together to find your clearest possible vision.
