Abstract: Disclosed is a pressure eye patch in which an inner membrane is positioned over the patient's eye and fixed thereto by means of adhesive on its inner side with an outer membrane which is superimposed over the inner membrane, thus forming a cavity that is interposed between the outer membrane and the inner membrane. There is an elongated longitudinal slit in the outer membrane which allows the outer membrane to be opened to allow access to the cavity. Cushioning material such as sterile gauze may be inserted into the cavity through this opening. Alternatively, a cooling or heating material may also be emplaced in the cavity. Instead of the elongated slit there may be a partial peripheral opening between the front and rear membranes to allow access to the cavity.

Abstract: A structural eye assembly is provided comprising replaceable components exhibiting healthy conditions, pathological states and post-surgical conditions, and a related method thereto. The assembly preferably comprises a spherical eye body of structural (sturdy) soft and somewhat pliable material in the shape of human eye, preferably in an enlarged scale relative to the human eye for the ease of observation of the various structural components. The assembly includes a cornea which is replaceable with a plurality of corneas exhibiting various pathological structures and structural damages. The removable cornea is made of a clear, soft and pliable material to simulate a human cornea. Corneal pathological states are exhibited on various replaceable corneas to allow the educator or physician to selectively demonstrate the pathological state to the student or patient.
