The Dohlman-Doane keratoprosthesis (KPro) offers a viable solution for corneal blindness, especially in non-immune conditions. This artificial cornea provides significant visual improvement in eyes with poor prognoses for traditional corneal transplants.

Area of Science:

  • Ophthalmology
  • Corneal Surgery

Background:

  • Corneal blindness presents a significant challenge, particularly in cases with a history of severe injury or graft failure.
  • Traditional penetrating keratoplasty may have a poor prognosis in such complex cases.

Observation:

  • This study evaluated 9 eyes in 8 patients receiving the Dohlman-Doane type 1 keratoprosthesis (KPro).
  • Patients had severe corneal disease, including alkali burns, graft failure, Stevens-Johnson syndrome, and thermal injury, with pre-operative best-corrected visual acuity (BCVA) of hand motions or worse.
  • Three patients had pre-existing glaucoma requiring Ahmed valve implantation.

Findings:

  • 88.9% of eyes achieved a BCVA of 20/100 or better, with 44.4% reaching 20/40 or better.
  • Postoperative complications included posterior capsule opacity (3 eyes), retroprosthetic membrane (3 eyes), glaucoma (2 eyes), corneal melting (1 eye), and fungal endophthalmitis (1 eye), all managed with specific interventions.

  • The Dohlman-Doane KPro demonstrated effectiveness in restoring vision in challenging corneal blindness cases.

    • Implications:

    • The Dohlman-Doane KPro is a promising alternative for corneal blindness with poor prognoses for conventional penetrating keratoplasty.
    • A key advantage is the avoidance of systemic immunosuppression.
    • Optimal outcomes were observed in patients with non-immune corneal diseases.
