Abstract:
1. An apparatus for practicing an ophthalmologic surgical technique of creating a continuous curvilinear capsulorhexis comprising: a flexible cellophane-type cover; a malleable body, which comprises a putty or clay material; said cover has a different color relative to said malleable body and comprises a first surface and a second surface; said cover further comprises a tearing property similar to anterior capsule of a human lens; the cellophane-type cover is wrapped substantially and tautly around the malleable body to create a relatively flat surgical practice surface, and said cover is readily removable from said malleable body for easy replacement; wherein, the malleable body is easily manipulated into different shapes by a user's hand, is able to provide adequate resistance to a surgical tool, is able to mimic physical characteristics of a human lens, and is able to be squeezed by the user's hand and transfer energy from the squeezing of the user's hand throughout the malleable body to the relatively flat surgical practice surface to further mimic the physical characteristics of the human lens capsule during surgery; wherein the relatively flat surgical practice surface is a smooth surgical practice surface relatively similar to the physical feel and touch of human anterior lens capsule, mimicking the human anterior lens capsule when flattened with the introduction of a viscoelastic material into the anterior chamber prior to the creation of the capsulorhexis; wherein application of an upward force, by the user's hand, to the cover and malleable body causes the malleable body to form a rounded configuration to simulate loss of viscoelastic material from a human eye due to wound distortion; whereby the smooth surgical practice surface substantially mimics human anterior lens capsule and lens structures for practicing the surgical technique of creating the continuous curvilinear capsulorhexis.
