Summary

Amniotic membrane transplantation effectively restores the corneal epithelium in partial limbal stem cell deficiency, improving vision and reducing symptoms. This safe procedure offers a viable alternative to other grafting methods.

Area of Science:

  • Ophthalmology
  • Regenerative Medicine
  • Corneal Surgery

Background:

  • Partial limbal stem cell deficiency (LSCD) compromises corneal health and visual function.
  • Current treatments for LSCD have limitations, necessitating alternative approaches.

Purpose of the Study:

  • To evaluate the efficacy and safety of amniotic membrane transplantation (AMT) for corneal surface reconstruction.
  • To assess the long-term outcomes of AMT in patients with partial LSCD.

Main Methods:

  • AMT was performed on 17 eyes of 15 patients after superficial keratectomy.
  • Patients were monitored for at least one year post-transplantation.

Main Results:

  • All eyes achieved a stable corneal epithelial surface, with no recurrence of epithelial defects.

  • Significant visual acuity improvement was noted in 92.9% of eyes with visual potential.
  • Pain, photophobia, vascularization, and inflammation were substantially reduced post-procedure.

    • Conclusions:

    • AMT is a safe and effective treatment for partial LSCD, promoting corneal epithelial stability.
    • AMT serves as a promising alternative to limbal autograft or allograft procedures.
