Abstract

The present invention relates to a model for surgical operation for an eye with cataract comprising a pig's eye which is prepared by injecting self hardening type chemicals into a crystalline lens capsule or into an empty crystalline lens capsule of said pig's eye, further relates to a model for an enucleating operation of a fallen nucleus lens which is prepared by falling the hardened chemicals into corpus vitreum by breaking posterior capsule of crystalline lens consciously.

Claims (21)

1. A model for cataract surgery, comprising:

a pig's eye which is prepared by injecting a self hardening chemical, said self hardening chemical being dibenzylidenesorbitol,

a water soluble cellulose resin,

glycerin and

N-methyl-2-pyrrolidone into a crystalline lens capsule of said pig's eye wherein said crystalline lens capsule of said pig's eye is empty.

2. The model for cataract surgery of claim 1 , wherein the self hardening chemical is injected from the posterior pole of said pig's eye.

3. The model for cataract surgery of claim 1 , wherein said crystalline lens capsule of pig's eye is emptied by phacoemulsification.

4. The model for cataract surgery of claim 1 , wherein said crystalline lens capsule of pig's eye is emptied by aspiration.

5. A model for cataract surgery in the corpus vitreum, wherein a false nucleus of a cataract is prepared by injecting a self hardening chemical, said self hardening chemical being dibenzylidenesorbitol,

a water soluble cellulose resin,

glycerin and

N-methyl-2-pyrrolidone into an empty crystalline lens capsule of a pig's eye wherein said crystalline lens capsule of said pig's eye is empty.

6. The model for cataract surgery of claim 5 , wherein said crystalline lens capsule of pig's eye is emptied by phacoemulsification.

7. The model for cataract surgery of claim 5 , wherein said crystalline lens capsule of pig's eye is emptied by aspiration.

8. A method of using a pig's eye having an empty crystalline lens capsule, comprising the step of:

injecting a self hardening chemical, said self hardening chemical being dibenzylidenesorbitol,

a water soluble cellulose resin,

glycerin and

N-methyl-2-pyrrolidone into an empty crystalline lens capsule of the pig's eye.

9. The method of claim 8 , wherein said crystalline lens capsule of pig's eye is emptied by phacoemulsification.

10. The method of claim 8 , wherein said crystalline lens capsule of pig's eye is emptied by aspiration.
