Main use:
CCE-YZ38 keratometer is mainly used to measure the radius of curvature and diopter of the cornea surface, and can also be used to measure the astigmatism axis of the human eye.

main feature:
        1. The CCE-YZ38 keratometer uses the Yevre cursor (rectangular and trapezoidal cursors) and the cursor is clear and perfect.
        2. The CCE-YZ38 keratometer is equipped with an astigmatism compensator: it can be used to compensate for astigmatic aberrations caused by the dual image system and the oblique reflection of the cornea. Adjusting this device can obtain a clear outline of the cursor, even in the case of special radii and diopter. is also like this.
       3. The cursor illumination source uses two high-brightness tungsten halogen bulbs with continuously adjustable brightness.
       4. The instrument is exquisite in design and flexible in operation. It is suitable for ophthalmologists to perform intraocular lens surgery on cataracts. When installing contact lenses or corneal lasers to treat myopia, the radius of curvature of the human eye is detected.
        5. The electric lifting platform is stable and low in noise.
