Area of Science:

  • Ophthalmology
  • Regenerative Medicine

Background:

  • End-stage dry eye significantly impairs vision.
  • Severe dry eye can result from conditions like pemphigoid and Stevens-Johnson syndrome.
  • Keratoprosthesis is a surgical option for eyes unresponsive to conventional treatments.

Purpose of the Study:

  • To evaluate the outcomes of keratoprosthesis implantation in patients with end-stage dry eye.
  • To assess the efficacy and safety of keratoprosthesis in complex ocular surface diseases.

Main Methods:

  • Retrospective case series of five patients with end-stage dry eye.
  • Patients underwent keratoprosthesis surgery.
  • Follow-up duration ranged from 6 to 22 months.

Main Results:

  • Two cases (40%) were considered surgical failures.
  • Three cases (60%) maintained good vision post-surgery.
  • The study included patients with pemphigoid and Stevens-Johnson syndrome.

Conclusions:

  • Keratoprosthesis implantation can restore vision in select patients with end-stage dry eye.
  • Outcomes are variable, with a significant proportion experiencing success.
  • Further research is needed to optimize patient selection and surgical techniques.
