Autorefractor Keratometer

Autorefractor Keratometer  – Ophthalmic ProductsAutorefractors are used to measure the degree of refractive error in the eye, and are suited well toward applications such as differentiating corneal from lenticular aberrations, and assessing pre-and-post refractive surgery patients. The patient focuses their vision on a fixation target such as a hot-air balloon floating over land. Like many ophthalmology instruments, they have spherical and cylindrical measurement ranges of -30 to +25D/±10D respectively. As the line between autorefractor and keratometer is often blurred, the customer should be aware of systems that have separate measurement ranges for autorefraction and keratometry.
