Pentacam mapping uses rotating Scheimpflug imaging to create three-dimensional maps of the cornea and anterior segment. It provides information on curvature, elevation, thickness and anterior chamber geometry from a single scan.
Parameters obtained
The system produces pachymetry, topography and elevation maps, along with indices that highlight irregular or ectatic patterns. It is sensitive to early keratoconus and post-surgical changes that may not be obvious clinically.
- Widely used in refractive surgery screening and planning
- Helps stratify risk for post-operative corneal ectasia
- Useful in evaluating eyes after corneal transplants or previous laser procedures
- Findings are interpreted together with other imaging and clinical examination
