Objective:

To explain the importance of anterior segment optical coherence tomography (AS-OCT) in the evaluation and management of specialty contact lenses, particularly in enhancing fitting accuracy and patient outcomes.

Key Findings:

• AS-OCT provides valuable imaging for tear meniscus assessment, crucial for dry eye evaluation, with specific metrics that guide treatment.
• It offers comparable readings to Scheimpflug-based tomography for corneal pachymetry, enhancing diagnostic confidence.
• AS-OCT is particularly effective for fitting scleral lenses, allowing for detailed measurements of corneal vault and limbal clearance, which are essential for successful lens wear.

Interpretation:

AS-OCT is a vital tool in specialty contact lens practices, enhancing the fitting process and improving patient outcomes through detailed ocular surface analysis.

Limitations:

• Significant differences in keratometry readings between AS-OCT and Scheimpflug devices limit their interchangeable use, which may affect clinical decision-making.

Conclusion:

AS-OCT is an essential technology for optometrists, improving the fitting and management of specialty contact lenses, ultimately leading to better patient outcomes.
