Next, in step S104, it is determined by the determination device 28 whether or not the acquired mobile data is within a certain range. Specifically, it is determined whether the moving speed is within 0 and 10 mm/sec or whether the moving direction is a perpendicular to the center passing through the pupil of the patient, and the angle is within 6 degrees.

If the result of the determination is Yes, the process proceeds to the next step S105, where it is determined that the keratoplasty lens is a registered lens that can be used for corneal correction. If the result of the determination is No, the process proceeds to step S108.

In step S105, if it is determined that the keratoplasty lens that can be used for treatment is used, in the next step S106, the morphological lens is used as the registration lens by the determining device 28, and the registered lens correction for the registered lens is performed. The D data and the registration lens movement data, the registration class data, and the registered patient data are sent to the database server 30.

In the database server 30, the registered lens correction D data accepting function 41, the registered lens movement data accepting function 42, the registered class data accepting function 43, and the registered patient data accepting function 44 are used to receive the transmitted data. And registered in the registered lens correction D data memory means 31, the registered lens movement data memory means 32, the registered class data memory means 33, and the registered patient data memory means 34. By repeating the above process, the database 30B is constructed.

Wherein, in the control means 40 of the database server 30, the cornea D data of the patient and the lens of the keratoplasty lens for correcting the cornea can be calculated by registering the patient data and registering the cornea/lens D difference data calculating means 45. The difference in the D data is corrected, and the result of the calculation is stored in the registered cornea/lens D difference data memory means 35 (refer to step S107).

As described above, the keratoplasty lens is attached to the cornea of the patient to determine whether the lens is usable, and the result of the determination is stored in the database. However, in step S108, if there is no subsequent lens, the database is terminated. In the construction process, if there is a subsequent lens, the process goes to step S109, the next Ortho-K lens is worn, and the next steps S102 to S108 are repeated.

Next, a procedure for determining a Ortho-K lens suitable for patient correction in the lens determination server 50 based on the data transmitted from the database device 30 and based on the data transmitted from the terminal device 70 will be described.

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

At this time, by the doctor 72, the data of the first class of the corneal correction system plural correction stage is input to the patient class data accepting function 83 by the IF means 70A by the keyboard 80A of the terminal device 70.

In addition, the lens data request information is memorized in the lens data request information memory means 98.

The patient data and the patient class data that are memorized are the patient data transmission function 84 and the patient class data transmission function 85 in the control device 80 of the terminal device 70. In addition, the lens data request information is obtained from the lens data. The request transmission 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, the patient data and the patient class data are accepted by the patient data receiving function 62 and the patient class data receiving function 63 in the control means 60, and are respectively stored in the patient data memory means 52 of the memory device 50B and Patient class data memory means 53. Further, the lens data request information is determined by the lens data request accepting and transmitting function 67A, and the determined lens data memory means 53A is stored in the memory device 50B. Further, when the doctor 72 contracts with the doctor 72, if the doctor 72 holds the lens camera equivalent to the lens camera 24, the information is input by the lens camera holding information receiving function 63A, and is stored in the lens camera holding information memory means 53B.

Proceeding to step S203, the database search means 64 of the lens determination server 50, based on the patient data or patient data and patient class data sent from the terminal device 70, from the database 30B in the database server 30 A registration lens having the same or similar data as the patient data and patient class data from the terminal device 70 is detected.

Proceeding to step S204, it is determined whether or not the difference between the registered cornea D data in the registered lens and the patient corneal D data in the patient data from the terminal device 70 is equal to or less than a predetermined value (for example, 0.03D).

If the result of the determination is Yes, the process proceeds to step S205, and the registration lens is used as the determination lens, and is stored in the determination lens storage means 56.

Here, the above "difference" is set to 0.01 mm of the radius of curvature of the cornea. This is considered to be a measurement accuracy limit of 0.01 mm for the measuring device. According to Table 3, when the radius of curvature is converted into the diopter (D), it becomes 0.03D.

Wherein, if there are a plurality of registered lenses of Yes, the cornea diameter data, the diameter of the patient's pupil diameter, and the registered lens diameter of the pupil diameter data may be determined as the lens.

The process proceeds from step S205 to step S205A, and it is determined whether or not there is a lens data request from the doctor 72. If No, the process proceeds to step S206.

The data R _{1 is} added or subtracted to calculate the corrected lens correction D data.

That is, the lens correction D of the average unit cornea D is obtained, and if r ₀ -r ₁ =Δr _{1 is} multiplied here, the lens correction D value (difference) corresponding to the difference between r ₀ and r ₁ is calculated, and D ₀ is This plus R ₁ can be. For example, as shown in FIG. 9A, when r ₀ > r ₁ > r ₂ and R ₁ > R ₂ , D ₀ = (r _{0 -} r ₁ = Δr ₁ ) × ΔL / ΔC + R ₁ . When r ₁ &gt; r ₀ &gt; r ₂ and R ₁ &gt _; R ₀ &gt; R ₂ , as shown in Fig. 9B, D ₀ = R _{1 -} Δr ₁ × ΔL / ΔC.

In the next step S211, it is determined whether or not the ΔL is equal to or less than a certain value, that is, whether the difference between the registered lens correction D data of the first lens and the second lens is excessively large. If it is too large, the reliability of correcting the lens correction D data is small. If the result of the determination is Yes, the process proceeds to step S212, and if it is No, the process proceeds to the following equation (B: Fig. 10).
