Summary
The Boston keratoprosthesis (BKP) offers improved vision for patients with severe corneal disease when traditional transplants fail. This study shows BKPs are a viable option, preserving sight in challenging cases.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Prosthetic Devices
Context:
- Corneal disease significantly impacts vision and quality of life.
- Penetrating keratoplasty (corneal transplant) has limitations for certain severe corneal conditions.
- The Boston keratoprosthesis (BKP) serves as an alternative surgical option.
Purpose:
- To summarize institutional outcomes using the Boston keratoprosthesis (BKP).
- To evaluate the efficacy and complications of BKP in patients with poor prognosis for corneal grafts.
Summary:
- This retrospective study analyzed 14 patients (age 36-78) who underwent BKP between November 2009 and August 2011.
- Patients presented with severe corneal opacification and surface loss, often after prior corneal grafts.
- Despite various complications, all patients experienced improved visual acuity, with some achieving significant gains.
Impact:
- The Boston keratoprosthesis (BKP) demonstrates effectiveness in restoring vision for complex corneal pathologies.
- BKP is becoming a crucial surgical intervention for eyes with a very poor prognosis for conventional corneal grafts.
- Further consideration for BKP reimbursement is necessary for broader accessibility.
