5 Key Takeaways

• 1

  Anterior segment optical coherence tomography (AS-OCT) is crucial for evaluating the ocular surface and managing specialty contact lenses.

• 2

  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.
