Collagen corneal shields offer potential for drug delivery and healing in various eye conditions. Further human studies are needed to fully assess their clinical benefits and applications.

Area of Science:

  • Ophthalmology
  • Biomaterials Science

Background:

  • Collagen corneal shields function as bandage lenses for ocular surface protection.
  • They are indicated for post-surgical, traumatic, and non-traumatic corneal conditions.

Purpose of the Study:

  • To review the evidence supporting collagen corneal shields in drug delivery and corneal wound healing.
  • To advocate for reassessment of their clinical application and benefits.

Main Methods:

  • Review of theoretical, experimental (animal), and clinical evidence.
  • Examination of collagen shield properties and applications in various ocular conditions.

Main Results:

  • Collagen shields show potential as drug delivery devices and in promoting epithelial and stromal healing.

  • Presoaking shields in pharmacological agents enhances drug delivery efficacy.
  • In microbial keratitis, they can improve drug delivery, healing, neutralize collagenases, and reduce inflammation.

    • Conclusions:

    • Evidence supports the role of collagen shields in drug delivery and corneal healing.
    • A lack of human studies, particularly randomized controlled trials, necessitates further investigation.
    • Reassessment of corneal collagen shields in clinical practice is recommended.
