We, the staff of JACRS Ltd., thank you for sharing your time with us today.  Please enjoy exploring in our homepage. In the hope of improving technology in ophthalmic operations and advancing its science, we have long been researching and developing ideal training methods to prepare for actual human ophthalmic operations. After many years of trial and error, at last, we are pleased to announce that we have finally succeeded in producing "Karton C," a reagent for CCC training, and "Karton N," a reagent for phacoemulsification training, as well as a new system that applies the above mentioned agents on butchered pig's eyes. With our "Karton System," any ophthalmologist can train himself for cataract operations beforehand in a situation quite similar to an actual operation.  Also, you can repeatedly do your training by re-applying Karton agents to the butchered pig's eye until you have a sure grip on the manipulation required for successful operations. You'd be surprised that you can hardly differentiate between a human cataract and a simulant cataract produced on a butchered pig's eye by our methods. The details are provided in further pages. Please have a look at them.  Thank you.
