Document Type and Number:
WIPO Patent Application WO/2024/007361
Kind Code:
A1
Abstract:
A fitting method and device for an orthokeratology lens. The method comprises: carrying out eye feature determination of a patient twice according to a set time interval, and respectively obtaining corresponding eye feature parameter sets (S01); comparing one by one corresponding parameters in the continuously-obtained eye feature parameter sets, and determining whether a deviation between any corresponding parameters exceeds a set value (S02); when the deviation between any corresponding parameters exceeds the set value, re-obtaining the eye feature parameter sets (S021), or otherwise, performing comprehensive calculation on the corresponding parameters, and using a calculation result as updated eye feature parameters to participate in new eye feature parameter sets (S022); and inputting the new eye feature parameter sets into a preset orthokeratology lens algorithm model to obtain orthokeratology lens fitting parameters (S03). According to the fitting method, the effect on the result caused by the deviations of the current state of the patient, the current state of equipment during one eye feature determination, and the current equipment operation mode is effectively reduced, and the accuracy and the stability of the final result are ensured.
