    Area of Science:

    • Ophthalmology
    • Biomaterials Science
    • Medical Device Engineering

    Background:

    • Corneal prostheses are crucial for restoring vision in cases of severe corneal damage.
    • Traditional corneal implants face challenges with biocompatibility and long-term stability.
    • Developing advanced biomaterials is essential for improving ocular prosthetic devices.

    Observation:

    • A new corneal prosthesis design utilizing aluminum oxide ceramic was engineered.
    • The prosthesis features a threaded optical cylinder with a 60-diopter refractive power.
    • The ceramic material exhibits excellent biocompatibility with ocular tissues.

    Findings:

    • Experimental studies demonstrate robust soft tissue adhesion to the aluminum oxide ceramic surface.
    • This adhesion effectively prevents implant extrusion and inhibits unwanted epithelial ingrowth.
