In described eye body cavity, be filled with physiological saline, refractive index is 1.3342.
Described pedestal upper surface is coaxially arranged with a circle groove two with eye body cavity, is provided with O RunddichtringO in groove two.
Described pedestal and simulation four pairs of screw and nut fixing seals for four jiaos, eye socket.
Described IOL Power is+19D that its centre distance anterior surface of cornea summit is 5.0mm, axial length 24.
Described artificial iris overall diameter is 9mm, and interior diameter is variable, uses black rubber to be made.
Described artificial cornea optical surface diameter is 10mm, and front surface radius-of-curvature is 7.72mm, and rear surface radius-of-curvature is 7.41mm, and optical center thickness is 0.55mm.
Described artificial cornea is fixed in slot with annular rubber ring.
On the conical surface of described simulation eye socket, be provided with the logical internal eye body cavity of 2 through holes.
Described simulated eye axial length 24mm.
Beneficial effect of the present invention:
(1) the present invention relates to a kind of design of new simulated eye, be different from the theoretical modeling eye in conceptive or optical simulation software in the past.
(2) the present invention has simplified the traditional fabrication pattern of simulated eye, and required parts are less, saves consumptive material, reduces costs.
