Auto keratometer, or an autorefractor keratometer, is a device used for the measurement of cornea anterior surface curvature across a fixed chord length. An auto keratometer provides central and peripheral curvatures of the cornea at different points and is used for measurement of astigmatism.
Commercial keratometers are a combination of automated keratometry and automated refractors. They are the most common modality for the measurement of the actual refractive error of the eye and refractive power.
Moreover, it also measures pupillary distance and pupil size. An auto keratometer principle is based on refraction; for example, the eye cornea anterior surface acts as a concave mirror and reflects the incoming light. A keratometer uses mires for the measurement of corneal curvature and mires are reflected from the corneal surface.

This reflection is taken as an image by keratometers and is used for refractive index calculation. Most keratometers are calibrated with an average refractive index of 1.3375 and this value might vary from device to device. This refractive index is used for the measurement of corneal curvature. Recent advancements in technology have led to the integration of different functions; for example, keratometers are also integrated with glare testing functions.
Increasing demand for auto keratometers due to the increasing prevalence of astigmatism fuels the growth of the auto keratometer market. Astigmatism is still a major concern in patients undergoing cataract surgery and on average, 30% of cataract patients suffer from preexisting astigmatism.
Inaccurate measurement of corneal curvature might lead to complete astigmatism. In order to overcome the parallax errors, manufacturers have developed automated keratometers.
Along with this, technological advancements have led to the integration of auto-refractors and glare testing with auto keratometers, which has boosted the growth of the auto keratometer market. Further, advancements in auto keratometers over manual keratometers to reduce the measurement errors have also increased adoption among end users.
Automated keratometers are more reliable and faster than the alternative techniques with high ease of use. Further, rising awareness of astigmatism among the patient population has further boosted the adoption rate of auto keratometers among healthcare centers.
All these factors are expected to drive the burgeoning growth of the auto keratometer market. The high cost of auto keratometers over manual keratometers is slated to slightly affect the growth of the market.
