Patients who meet all of the following criteria are eligible (1) Men and women who are at least 20 years old and less than 90 years old at the time of consent. (2) Patients have been diagnosed with anterior segment diseases. (3) Patients who have received a thorough explanation of their participation in this study, and who have given written consent of their own free will based on sufficient understanding.

Design outcomes

Primary

Measure	Time frame
The percentage of agreement between the findings diagnosed (judged) by an ophthalmologist on examination with a conventional instrument such as a slit-lamp microscope and the findings diagnosed by a physician from images taken with this study instrument. The findings shall be as follows. The percentage of agreement between the calculated values of the cell analysis algorithm of this instrument and the SUN grading (physician's findings) using a slit-lamp microscope. The percentage of agreement between the SUN grading of flares using this instrument, SUN grading using a slit-lamp microscope, and measurements using a laser flare meter. Agreement rate between the Emery-Little classification of cataracts using this device and the Emery-Little classification using slit-lamp microscopy. Agreement rate between corneal curvature measured with this device and corneal curvature measured with anterior segment optical coherence tomography. Regarding the safety evaluation, the risk of this device is sufficiently low and its safety is well established.	—
