Advancements in keratoprosthesis (KPro) materials and surgical techniques show promise for treating corneal blindness. Despite progress, the global application of KPro remains limited, with outcomes varying by diagnosis.

Area of Science:

  • Ophthalmic biomaterials science
  • Corneal transplantation research
  • Biomedical engineering for vision restoration

Background:

  • Keratoprosthesis (KPro) aims to restore vision in cases of severe corneal blindness.
  • Existing KPro materials include porous polytetrafluoroethylene, polyurethane, and poly (2-hydroxyethyl methacrylate) copolymers.
  • Novel fixation methods like scleral haptics enhance KPro device stability.

Purpose of the Study:

  • To review recent advances in keratoprosthesis design, materials, and management.
  • To assess the current state and future directions of KPro technology.
  • To highlight challenges in the global application of KPro for corneal blindness.

Main Methods:

  • English language literature review conducted from January 1, 2000, to April 1, 2001.

Related Experiment Videos

  • Focused on advancements in KPro materials, fixation, surgical techniques, and outcomes.
  • Analysis of factors influencing KPro prognosis and complications.

    • Main Results:

    • Promising biointegratable materials like porous PTFE and PU have been developed.
    • Scleral haptics offer improved KPro stability.
    • Prognosis varies significantly with preoperative diagnosis, impacting endophthalmitis risk.
    • Modified vitreoretinal techniques address posterior segment complications.

    Conclusions:

    • The field of keratoprosthesis is rapidly evolving with new materials and surgical approaches.
    • Despite scientific progress, the worldwide use of KPro for complex corneal blindness is still limited.
    • Further research and development are needed to expand KPro accessibility and efficacy.
