A patient with keratoconus is being prescribed a scleral contact lens. Which of the following is the most important step in fitting a scleral contact lens for keratoconus?

Perform keratometry
Perform topography
Measure tear film quality
Measure corneal thickness

Explanation

Answer: A - The most important step in fitting a scleral contact lens for keratoconus is performing keratometry.

Keratometry is a critical aspect of fitting scleral contact lenses for keratoconus, as it provides important information, such as the radius of curvature and corneal astigmatism, that helps to determine the overall design of the lens. Additionally, keratometry helps to identify any changes in the corneal curvature that could affect the fit and performance of the lens.
