Title:
CORNEA OPERATION DEVICE AND CORRECTION DATA DETERMINING METHOD
Document Type and Number:
Japanese Patent JP3860405
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make performable accurate correction by finding a proper correction pattern that a patient desires.
SOLUTION: A contact lens for trial use is selected after obtaining a correction value by a contact lens based on the results of optometry, and refractivity data of the contact lens is inputted to a cornea operation device correcting an abnormal refraction by ablating cornea tissue by laser beams when the results of trial use are satisfactory. The device converts the inputted refractivity data into ablation data to control the ablation amount of cornea tissue based on the ablation data.
