Boston Keratoprosthesis: expanding the boundaries

Abstract

The Boston Keratoprosthesis (KPro) has enjoyed good results in the adult population, particularly through its rapid clearing of the visual axis, its excellent retention rate, and the paucity of postoperative complications in recent years. Design modifications, enhanced surgical technique, and improved postoperative management have made keratoprosthesis surgery a reality in the twenty-first century and an excellent alternative for poor PK candidates.

“…3 Theoretically, the clear optical stem of the Boston keratoprosthesis, with its spherical cut, would eliminate corneal regular and irregular astigmatism associated with PK and allow a BSCVA soon after surgery. 21 However, postoperative refraction depends on other several factors such as suturing, wound healing, IOP, and lens status. The high residual astigmatism that occurred in a few patients was because of intraocular lens tilt and decentration.…”
