The difference of the D data is corrected, and the calculation result is stored in the registered cornea/lens D difference data storage means 35 (refer to step S107).

As described above, the orthokeratology lens is repeatedly attached to the patient's cornea, it is determined whether the lens is usable, and the determination result is stored in the database. However, in step S108, if there is no next lens, the database is terminated. During the construction process, if there is a next lens, then proceed to step S109 to put on the next orthokeratology lens, and repeat the next steps S102 to S108 again.

Next, the process of determining the most suitable orthokeratology lens for patient correction in the lens determination server 50 based on the data transmitted from the terminal device 70 using the data stored in the database 30B of the database server 30 will be described.

As shown in FIG. 8 , in step S201 , in the terminal device 70 , the patient data obtaining device 71 obtains the data of the patient cornea D, the corneal diameter, and the pupil diameter of the patient whose cornea is to be corrected. The patient data is sent to the lens determination server 50 through the Internet 14 (refer to step S202).

Patient Class Data Memory Means 93. In addition, the lens data request information is stored in the lens data request information memory means 98.

The memorized patient data and patient class data are transmitted through the patient data sending function 84 and the patient class data sending function 85 in the control device 80 of the terminal device 70. In addition, the lens data request information is obtained through the lens data. The request sending function 89A is sent to the lens determination server 50 via the IF means 70A and the Internet 14 .

In the lens determination server 50, patient data and patient class data are accepted by the patient data accepting function 62 and the patient class data accepting function 63 in the control means 60, and stored in the patient data storing means 52 and Patient Class Data Memory Means 53. In addition, the lens data request information is received by the determined lens data request reception and transmission function 67A, and is stored in the determined lens data request storage means 53A in the memory device 50B. When contracting with the doctor 72, if the doctor 72 has a lens camera equivalent to the lens camera 24, the information is input by the lens camera holding information accepting function 63A and stored in the lens camera holding information storage means 53B.
