Not all patients see better after cataract surgery. In large part, this can be avoided by the RAM test. The usual cause of a poor outcome is a SECOND disease of the eye was not identified by the standard pre-surgical exam.
To fully understand the ability of the eye to see, the FUNCTION must be measured. The potential vision or retinal acuity must be measured, not just the current visual acuity. Modern scans show marvelous details but do not measure function. An eye with a "normal" scan can have poor functional capacity.
The RAM provides the patient a window through the cataract and this allows an accurate measure of the ability of the eye to see.
Cataract surgery is the only operation on the human body in which the functional outcome can be accurately measured before surgery, but by custom this measurement is rarely performed.
The BAM utilizes calibrated glare to quantify the degree of vision loss due to cataract. Occluding the BAM glare bowl allows for macular photo stress testing, a component to identify diseases of the macula. Design - handheld, stand alone Illumination - high, medium, low intensity... Read more
