Abstract
A corneal surgery apparatus for correcting a refractive error by ablating corneal tissue with a laser beam, being capable of finding a correction pattern optimum for a patient to ensure precise correction, and a method of determining correction data. The apparatus includes units for inputting refractive power data on a trial contact lens, converting the refractive power data to obtain ablation data, controlling an ablation amount of the corneal tissue based on the ablation data, storing the refractive power data corresponding to each contact lens, and revising the refractive power data. The method includes processes for obtaining a correction value made with a contact lens based on of an ophthalmic examination, selecting a contact lens based on the value and converting the refractive power data on the selected contact lens into the ablation data for correcting the refractive error if the trial use of the contact lens results favorably.
