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.

What is claimed is: 1. A method for determining a corneal ablation amount of a patient's eye, the method comprising the steps of: inputting a correction amount of the eye, a first size of a first ablation zone for securing the correction amount, and a second size of an ablation area including the first ablation zone and a second ablation zone which is formed outside the first ablation zone and connects the first ablation zone with a non-ablation area; dividing the inputted correction amount into at least ten; determining respective ablation sizes corresponding to the divided correction amounts while gradually enlarging them within a range from the first size to the second size according to the number of the divided correction amounts; determining divided corneal ablation amounts based on the divided correction amounts and the corresponding ablation sizes respectively; and determining a total corneal ablation amount of the eye by summing the divided corneal ablation amounts. 2. The method according to claim 1, wherein the inputting step inputs the second size by inputting a size of the second ablation zone. 3. The method according to claim 1, wherein the dividing step divides the inputted correction amount in accordance with a set divisional proportion.
