The prepurchase examination.

The prepurchase examination is performed to aid a prospective purchaser in determining the suitability of a specific patient for an anticipated use and, perhaps, an intended rider. The ophthalmic portion of that examination can be performed satisfactorily with minimal equipment by following a systematic protocol that includes examination of all segments of the globe and an evaluation of the patient's vision. Findings of the examination should be discussed with and made in writing to the buyer so that he or she can make an informed decision about the suitability of the purchase.
