Axial Length Estimator

Enter the measurements: ? Please enter the most recent refraction data here indicating if you have refracted under cycloplegia. You can choose to enter keratometry readings in millimetres (mm) or dioptres (D). All other values are in mm. We correct for back vertex distance (BVD) so you don't have to.

Axial Length Estimate: ? Cycloplegic SERE:
The 95% limits of agreement for the two measures are ±0.73mm (±3.0%) of the mean axial length measurement.
Non-Cycloplegic SERE:
The 95% limits of agreement for the two measures are ±0.73mm (±3.0%) of the mean axial length measurement.

By the time a young myopic child has grown up, their prescription (and therefore their axial length) is likely to have grown with them.1
