Purpose:
To describe 9 eyes in 8 patients who received Dohlman-Doane type 1 keratoprosthesis (KPro) with a mean follow-up of 11.2 months (2 to 25 months).
Methods:
A retrospective, non-comparative interventional case series. Previous corneal disease was alcaline burn in 4 eyes, multiple graft failure in 3 eyes, Stevens-Johnson syndrome in 1 eye and thermal injury in 1 eye. Best corrected visual acuity (BCVA) was hand motions or worse in all patients. Glaucoma was present preoperatively in 3 eyes and received Ahmed valve implantation.
Results:
88,9% eyes achieved BCVA of better than or equal to 20/100, and 44,4% better than or equal to 20/40. In the postoperative period, 3 eyes developed posterior capsule opacity treated with YAG laser capsulotomy; 3 retroprosthetic membrane treated with tPA injection or steroids; 2 glaucoma in clinical treatment; 1 corneal melting, treated with donor cornea bottom exchange; and 1 fungic endophthalmitis, treated with corneal transplant, anterior vitrectomy, KPro and intraocular lens explantation, and specific intravitreal and endovenous treatment.
Conclusion:
Dohlman-Doane K-Pro seems to be a good option for cases of corneal blindness with poor prognosis for traditional penetrating keratoplasty. Its main advantage is not requesting systemic immunossuppression. Best results were achieved in non-immune diseases.
