Optical Biometer + Corneal Topographer

Build, Manage, and Grow your Pediatric Myopia Management Practice

The MYAH is a versatile instrument, including optical biometry, corneal topography, pupillometry, anterior cornea wavefront analysis, and contact lens fitting tool. It is a comprehensive device for monitoring axial length, evaluating the corneal surface, assessing visual quality, and fitting specialty lenses. Analysis tools plot changes in axial length, refraction, and corneal power; highlight differences in corneal shape between visits; and map higher-order aberrations.

Product Features

Maestro2 Features

Measure Axial Length

Quickly captures baseline axial
length measurements to aid in risk assessment.

Monitor Change Over Time

Exclusive software tracks changes in Rx and axial length measurements over time to show progression and response to treatment.

Maximize Your Investment

Our Practice Implementation and Marketing Toolkit helps you integrate new technology into your practice and promote expanded services to your patients.

MYAH offers an efficient, affordable, and repeatable way to baseline axial length and monitor changes over time.
