Boston keratoprothesis

Keratoprostheses are “artificial corneas” that help restore vision in situations where the cornea and ocular surface are so severely damaged that a donor corneal graft would not be feasible.

Since 2005, 13,000 Boston keratoprostheses have been implanted worldwide.

The Boston keratoprosthesis essentially consists of a mushroom-shaped plastic (PMMA) optical cylinder that acts like a lens, around which a donor cornea is placed. At the back, a titanium backplate prevents the cornea from detaching from the optic.

The indications for Boston keratoprostheses include corneal diseases with dense opacities where a corneal graft would not work or would be rapidly rejected.

Conditions that may benefit from a Boston Keratoprosthesis include : multiple failed corneal grafts, limbal stem cell deficiency, aniridia, corneal neovascularization and ocular burns

Visual outcomes are generally very good in the absence of complications.
