Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Medical Imaging

Background:

  • Corneal epithelial thickness mapping is increasingly utilized in refractive surgery.
  • Advances in imaging technology have made this technique more accessible.

Purpose of the Study:

  • To review the applications of corneal epithelial thickness mapping in refractive surgery.
  • To highlight its role in diagnosis and treatment planning.

Main Methods:

  • Analysis of epithelial thickness profiles in normal and pathological eyes.
  • Correlation of epithelial changes with stromal curvature and eyelid influence.
  • Review of clinical applications in various corneal conditions.

Main Results:

  • Normal eyes exhibit a non-uniform epithelial thickness (thinner superiorly and nasally).
  • Epithelial thickness changes predictably compensate for stromal curvature, influenced by the eyelid.
  • Applications include keratoconus screening, ectasia monitoring, and hyperopic treatment planning.
  • Epithelial maps aid in diagnosing irregular astigmatism and planning trans-epithelial PRK.
  • Dry eye, dystrophy, and ptosis can also affect epithelial thickness.

Conclusions:

  • Epithelial thickness mapping is essential for refractive surgery.
  • Key applications include keratoconus screening, ectasia monitoring, and hyperopic treatment planning.
  • It is also crucial for therapeutic diagnosis and treatment strategies.
