Modified MEM retinoscopy improved card design for accuracy and ease of use

1 December 1998


MEM retinoscopy is an excellent reliable method of determining accommodative posture. However, there are two basic problems that make traditional MEM retinoscopy a rarely practiced procedure in primary care optometry. First, the traditional MEM procedure requires a clinician to hold three pieces of equipment simultaneously. This is a clumsy and cumbersome which translates to extra time. (A clinicians' nightmare) The second problem is the characters used on the various MEM hole cards. They are not specific for age demand or task demand. This factor can result in unreliable accommodative posture measurements. The modified MEM cards are designed to alleviate these two problems. First, a simple apparatus has been constructed to secure the MEM hole card to the retinoscope. This results in the clinician only having to hold the retinoscope and the neutralizing lens. Second, the modified MEM cards have been designed with regard to age demand and task demand. These cards will render a more accurate, task specific measurement of accommodative posture. The modified MEM cards make MEM an accurate and easy to use procedure clinicians can incorporate into their exam sequence.
