ABSTRACT:
A corneal surgery apparatus capable of reducing parts where a corneal curvature suddenly varies, and an apparatus for determining a corneal ablation amount. The corneal-ablation-amount determining apparatus includes a data input unit which inputs data on a correction amount of a patient's eye and data on a size of a second ablation zone for connecting a first ablation zone for securing the correction amount with a non-ablation area, a calculation unit which divides the inputted correction amount into at least ten, obtains an ablation amount for each divided correction amount as a lens component is ablated according to a size gradually enlarged from the first ablation zone to an outer diameter of the second ablation zone for each divided correction amount, and determines a total ablation amount by summing each obtained ablation amount, and an output unit which outputs data on the determined ablation amount.
