Measurement of Axial Length & Axial Length/Corneal Radius Ratio

AL550 provides accurate measurement parameters such as axis length (AL) and axis length/corneal radius ratio (AL/CR), which facilitates eye-care professionals in evaluating the current status of myopia progression of children and adolescents, so as to adopt appropriate myopia intervention measures.

Trend Curve of Axial Length, Axial Length/Corneal Radius Ratio & Myopia Probability

AL550 provides the trend curves of axial length and axial length/corneal radius ratio of children and adolescents, which is compared with age-specific and sex-specific percentile curves for axial length, myopia & high myopia probability in the European and Asian population, and allows eye professionals to record myopia interventions so as to provide important evidence for monitoring myopia progression in children and adolescents, evaluating the effectiveness of current myopia interventions and predicting future myopia and high myopia risk.

Axial Length Variation over Time

AL550 provides change curve of axial length variation, which enables eye-care professions to accurately observe and evaluate the effectiveness of myopia prevention and control measures.

Selection of Orthokeratology Trial Lens

AL550 provides orthokeratology lens fitting-related parameters including flat K, steep K, astigmatism, flat eccentricity, steep eccentricity, corneal sagittal height difference, offering comprehensive data support for eye-care professionals to select orthokeratology trial lenses.

Orthokeratology Lens Simulated Fitting

Based on patient’s corneal parameters, AL550 can simulate the fitting effect of orthokeratology lenses under the corneal fluorescence staining with slit lamp. This helps eye-care professionals improve the efficiency of orthokeratology lenses fitting and avoid patient discomfort and inconvenience caused by multiple trial lenses changes.

Evaluation of Orthokeratology Lens Wearing Effect

AL550 provides tangential curvature difference maps before and after lens wear, which can assist eye-care professionals in evaluating the wearing effect of orthokeratology lenses.
