MYAH Technology: Advanced precision for myopia control and eye health

What is MYAH?
MYAH is a multifunctional device that allows for highly accurate analysis of the eye’s shape and structure. It combines optical biometry, corneal topography, pupillometry, and dry eye assessment tools in a single device. Thanks to this technology, we can obtain detailed information about the cornea, measure the length of the eyeball, and study the behavior of the tear filmâall quickly, painlessly, and non-invasively.
Control of childhood and adolescent myopia
Myopia is one of the most common vision problems, especially in children and adolescents, so halting its progression is essential as it can increase the risk of eye diseases in adulthood. At Presbit, we use MYAH to precisely monitor the progression of myopia, measuring not only the prescription but also the axial elongation of the eye, the most important parameter for assessing its progression. This information allows us to design personalized strategies to slow or stabilize myopic progression, using special contact lenses, optical treatments, or medications tailored to each patient.
Detailed analysis of the cornea
Thanks to its corneal topography system, MYAH generates three-dimensional maps of the eye’s surface, essential for:
- Detect corneal irregularities or deformities (such as keratoconus).
- To accurately fit custom contact lenses or Ortho-K.
- Plan refractive treatments with greater safety and accuracy.
- Dry eye assessment and visual comfort.
Benefits for the patient
- Comprehensive and accurate diagnosis in a single examination.
- Objective monitoring of myopia with comparative reports.
- Greater safety in the fitting of contact lenses or refractive treatments.
- Early detection of corneal alterations and dry eye.
- Comfortable and contactless experience, ideal for children and adults.
- Innovation at the service of your vision
