    AS-OCT measures tear meniscus height and area, differentiating between healthy eyes and those with dry eye disease.

  • 3

    AS-OCT aids in early detection of keratoconus and assesses corneal ectasia and thinning, providing comparable results to Scheimpflug imaging.

  • 4

    The technology is essential for fitting rigid lenses, allowing precise measurement of corneal gas permeable lens clearance.

  • 5

    For scleral lenses, AS-OCT evaluates central corneal vault and limbal clearance, guiding fitting adjustments based on detailed measurements.
