5 Key Takeaways

1

The contact lens industry is evolving, emphasizing sagittal height in fitting various lens types, including scleral and rigid corneal lenses.
2

Myopia management focuses on axial eye length in millimeters, with finer measurements expressed in microns for precision.
3

Choroidal thickness, measured in microns, can indicate risks for myopic macular degeneration and assess treatment efficacy.
4

Contact lenses are increasingly described by height in microns, enhancing clarity in fitting and understanding ocular surface interactions.
5

Corneal topography technology utilizes microns to analyze ocular surface elevation, crucial for effective contact lens fitting.
