A new alloplastic material for ophthalmic surgery

D W Lamberts, S C Grandon

    Ophthalmic Surgery
    |December 1, 1978
    PubMed
    Summary

    Proplast, an inert alloplast, shows promise in ocular surgery, potentially solving implant erosion and slippage issues. Early rabbit studies indicate good tissue integration for corneal and scleral implants.

    Area of Science:

    • Ophthalmic surgery
    • Biomaterials science

    Background:

    • Current ocular implants face challenges with erosion and slippage.
    • Proplast is an inert, porous alloplast composed of carbon and Teflon.

    Purpose of the Study:

    • To investigate the potential of Proplast as an implant material in ocular surgery.
    • To evaluate Proplast's biocompatibility and tissue integration in corneal and scleral implants.

    Main Methods:

    • Surgical implantation of Proplast into the cornea and sclera of rabbits.
    • Microscopic examination of explanted implants to assess tissue ingrowth.

    Main Results:

    • Proplast implants were well-tolerated in rabbit corneal and scleral models.
    • Microscopic analysis revealed fibrovascular ingrowth into the porous matrix of Proplast, indicating host tissue incorporation.

    Conclusions:

    • Proplast demonstrates potential as a biocompatible material for ocular implants, offering a possible solution to common implant complications.
    • Further research is needed to determine the rate of tissue incorporation and long-term acceptance of Proplast in vivo.
