Cessation of contact lenses prior to corneal tomography for keratoconus monitoring: results from a clinician survey

Year: 2024

Type: article

Abstract: Corneal tomography is essential in diagnosing and monitoring corneal ectasias, including keratoconus. Monitoring may be necessary to determine whether the disease is progressing and if corneal cross-linking is indicated, or to track progression following corneal cross-linking. It is important for tomographers to provide precise (repeatable and reproducible) measurements to detect progression [ 1 ], although achieving this precision is more challenging in eyes with keratoconus [ 2 ]. Visual improvement in eyes keratoconus is typically managed with hard contact lenses. Contact lenses may induce tomographic changes to the corneal shape. This can interfere with our ability to accurately distinguish between pathological changes due to disease progression and temporary physiological changes caused by contact lens usage.
