Features:
1.This keratometer was developed under the guidance of optometry center.
2.This instrument can give a precise examination of the radius of curvature of the anterior corneal surface and it also give a exam of axis and diopter of cornea astigmatism.
3.This measurement is utilized to fit contract lenses and to monitor corneal lenses.
4.Keratometer are occasionally used to assist in the recognition of certain corneal abnormalities and to check the radii of curavature of both hard and soft contact lenses.
5.The program can be operated with considerable ease
