Measuring Myopia Progression

Control you can’t measure is just hope.

The promise of myopia management is a slower curve — and a curve needs points. At every check we compare your child’s prescription, corneal maps and eye measurements against baseline, so the plan is judged by data, not impressions.

The dashboard

Three numbers tell the story.

The prescription trend

The slope across years, not this year’s number. Flattening that slope is the goal.

Corneal maps

Especially for Ortho-K wearers: topography confirms the lens is shaping exactly as designed, visit after visit.

Eye measurements

The key dimensions that guide treatment choice at the start and verify the response as your child grows.

When the data says “still progressing,” that’s not failure. It’s the signal to adjust: strengthen an option, or combine two, when appropriate.

The cadence

Checks that fit a school year.

  • Baseline evaluation sets the starting point
  • Follow-ups track response through the growth years
  • Stability earns longer intervals; change tightens them

Common questions

Measuring progression, answered.

Anything else, call the office at 310-828-2010.

  • Follow-up cadence is set by age, option and pace of change — faster-changing eyes are simply seen more often.

  • A flatter prescription slope than the child was on before treatment — measured, not assumed.

  • Sometimes, when measurements justify it — atropine can be paired with optical options in appropriate cases.

  • Axial length is the length of the eye from front to back, measured in millimeters. Myopia develops when a child's eye grows too long, so distant images focus in front of the retina, and slowing that growth means less myopia. Measuring length shows the growth directly. Myopia studies track the change in eye length along with the change in prescription, and progression checks compare eye measurements and the prescription with your child's baseline. Length also matters later in life: slowing myopia in childhood may lower the risk of complications such as retinal detachment and glaucoma.

  • It depends on age and background. In urban children wearing ordinary single-vision glasses, a 2012 analysis of 20 studies estimated about 0.55 diopters of change over one year at an average age of 9.3 in mostly European populations, and 0.82 diopters in Asian populations. A diopter is the unit a glasses prescription is written in. Younger children progressed faster, and the pace slowed with age. Your child's own slope is what the checks track, so bring past prescriptions to the first visit to start the trend line.

The myopia estimator

What slowing it down looks like, on your child’s numbers.

Set the age, prescription and risk factors, then compare Ortho-K, atropine, multifocal contacts and Stellest against doing nothing.
