On January 19, 2026, the 7th MRT Lecture: Seminar on Peripheral Refraction Measurement Technology was successfully held. We were honored to invite Jiang Lin, Vice President of Aier Eye Hospital (Sichuan Region). Focusing on core clinical challenges, President Lin provided a deep dive into the underlying logic behind "differences in myopia control outcomes," delivering an academic feast centered on mechanism exploration, technical application, and precision decision-making.

1. Current Reality: Exploring Mechanisms Amid Severe Challenges

To open the session, President Lin addressed the stark reality of myopia prevention and control among Chinese youth: the escalating prevalence and the trend of onset at younger ages. In this context, traditional prevention and control strategies are facing immense challenges.

To solve the problem, one must first trace its roots. President Lin systematically elaborated on the core mechanisms of myopia development—ranging from accommodative lag and peripheral defocus to scleral hypoxia—peeling back the layers of complexity. He pointed out that only by deeply understanding these physiological mechanisms can clinicians explain why some children’s prescriptions surge rapidly while others remain effectively controlled.

2. Technological Breakthrough: MRT Redefines "Precision"

In the era of precision control, the value of objective diagnostic data is more prominent than ever. President Lin highlighted the core clinical value of MRT (Multispectral Refraction Topography), emphasizing its precision and convenience in clearly mapping peripheral retinal refraction. MRT is more than just an exam; it is the cornerstone of treatment planning. By transforming "defocus" from a vague concept into a visualized topography, it provides scientific, quantitative data for customized defocus lenses. These lenses, optimized through MRT data, generate ideal myopic defocus to more effectively slow axial elongation and myopia progression.

3. Strategy Upgrade: From "One-Size-Fits-All" to "Individualized Care"

This is the core thesis of the lecture. Through detailed case studies, President Lin interpreted the specific application scenarios for mainstream myopia control methods, including Orthokeratology (Ortho-K), customized defocus lenses, and low-concentration atropine.

Why do outcomes vary so much? The answer lies in "matching."

The meeting emphasized the urgent need to move away from the traditional "one-size-fits-all" model. Clinicians must conduct comprehensive assessments based on the specific stages of myopia (pre-myopia, progressive, and high myopia stages), integrating axial length data, peripheral refraction status, and individual differences. By precisely matching diagnostic tools with intervention measures and crafting individualized prevention plans, we can overcome the challenge of inconsistent effectiveness and achieve a qualitative leap from simple "management" to true "control."

The seminar resonated deeply with the participating experts. During the discussion session, attendees engaged in spirited exchanges regarding personalized management decisions for various patient types and the optimization of combination therapy protocols.

A professional consensus was reached: The integration of MRT technology with customized defocus lenses marks a new era of precision management in myopia control. Supported by multidimensional data and a flexible combination of interventions, the standard of clinical prescription and fitting will be significantly elevated.
