Build, Manage, and Grow Your Myopia & Dry Eye Practice with MYAH

Monitor the progression of myopia and the effectiveness of intervention.

The Rx and Axial Length charts help you track progression and monitor the effectiveness of intervention. MYAH provides this data so that you can compare changes over time. It also uses the same proven technology as the Topcon Aladdin biometer, producing reproducible axial length results.1

BUILD your Myopia Management Service

MYAH provides the initial baseline to monitor risk, allowing you to start the conversation early with parents.

MANAGE: To Treat or not to Treat?

MYAH provides essential information to assess the risk of myopia and for close monitoring of the effectiveness of any myopia interventions.

GROW your Myopia Management Service

Offering axial length screening tests may complement your refraction tests.

MYAH offers all the technologies required to support myopia management: optical biometry, corneal topography and pupillometry—it is a one-time investment. In addition, MYAH is an all-in-one device that offers an evolving platform which provides the tools to add or grow Dry Eye Management.

Myopia greatly impacts the quality of life and personal development of children.2

It has never been a better time to join the battle against the global myopia epidemic. MYAH is the perfect instrument for eyecare professionals interested in building, managing, and growing a myopia service. Building a myopia management practice requires you to educate your patients and their families about the implications of myopia progression, to manage the condition and to grow your service offering.

Key Features

Dynamic Pupillometry
Provides clear information on the reaction time and size of the pupil, which may be useful to monitor low dose atropine compliance or to titrate the dose of atropine. The user can examine pupil centration and diameter over a range of light levels, which is useful for Ortho-K and multifocal lens fitting, and is also informative for pre and post-refractive surgery.

Contact Lens Fitting
MYAH provides support for contact lens fitting, reducing the number of lenses that need to be trialed on the eye:
• Includes a database of conventional RGP and Ortho-K lenses.
• Export topography data to 3rd party calculator
• Fluorescein simulation with ability to save and review data.

Dry Eye Assessment Tools
These tools offer non-invasive Tear Break-up Time (NIBUT), Meibomian gland imaging with the area of loss analysis, tear meniscus height analysis, blink analysis, real fluorescein imaging and video acquisition, and video review of anterior corneal aberrations between blinks.

Corneal Topography
MYAH offers another range of tools to analyze the anterior cornea, including topographic maps, 3D maps, comparison maps, height maps, Zernike analysis and keratoconus screening.

Corneal Aberration Summary
The Zernike expansion coefficient is used to determine which component(s) dominate the aberration structure of the cornea and to what degree. The anterior corneal Zernike summary consists of 36 polynomials up to the 7th order and provides a clear view of the optical irregularities that can impact the quality of vision.
