Overnight corneal reshaping (OCR) shows no adverse effects on corneal endothelium structure. Properly fitted OCR lenses may reduce corneal endothelial polymegathism and pleomorphism compared to standard contact lenses.

Area of Science:

  • Ophthalmology
  • Corneal Physiology
  • Contact Lens Technology

Background:

  • Limited data exists on corneal endothelial structure during overnight corneal reshaping (OCR).
  • Understanding endothelial changes is crucial for contact lens wearers transitioning to new modalities.

Purpose of the Study:

  • To investigate corneal endothelial cell structure in various environments.
  • To compare endothelial changes between standard contact lens wear and OCR.

Main Methods:

  • Patients were categorized based on contact lens wear environments.
  • A comparative analysis was performed between contact lens users and those transitioning to OCR.

Main Results:

  • No observable adverse effects on the corneal endothelium were noted with OCR.

  • The study focused on structural integrity rather than visual acuity.

    • Conclusions:

    • Overnight corneal reshaping (OCR) lenses, when properly prescribed and monitored, can potentially decrease corneal endothelial polymegathism and pleomorphism.
    • OCR may offer an advantage over certain standard contact lenses in maintaining corneal endothelial health.
