Abstract:
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.
