Abstract (en)
[origin: WO8806329A1] A simulated human ocular system for practicing the surgical techniques required for the removal of cataractous lenses utilizing posterior chamber lens emulsification and, optionally, the techniques required for small incision implantation and refractive surgery. A human eye is generally imitated by an outer orb (5) having three inner, connected chambers separated by membranes that correspond to the cornea (23), the iris (29), and the posterior chamber, membrane (17). The lens phantom (21) consists of a structured, water-sensitive composition, such as a cross-linked gelatin to which a water soluble polymer has been added, and is thereafter encapsulated within a transparent vinyl or vinylidene chloride copolymer film. Placement of the ocular system in a structure (57) that duplicates the outside features of a human head, with provisions for varying the rotation and degree of ocular projection, completes this ocular model.
