Objective:

To describe the clinical course and rationale for replacing type I Boston keratoprosthesis (BKPro) with type II BKPro in two patients with complex ocular surface disease.

Approach:

Key Findings:

• Both patients experienced significant complications with type I BKPro, including corneal melt and recurrent eyelid complications, necessitating the switch to type II BKPro.
• The type II BKPro provided enhanced protection and stability in the context of severe ocular surface disease, as evidenced by improved management of intraocular pressure.
• Postoperative outcomes showed improvement in visual acuity, with one patient reporting increased perception of light and clarity.

Interpretation:

Limitations:

• The study is based on only two case reports, limiting generalizability to a broader patient population.
• Long-term outcomes and broader implications of such exchanges are not fully explored in this report.

Conclusion:

The exchange of type I to type II BKPro can address complications in patients with severe ocular surface disease, demonstrating its therapeutic value.
