Boston Keratoprosthesis Type I for corneal blindness

Patient organisation comments

The Royal National Institute of Blind People said that the Boston KPro technology provides a next step for people with a complicated corneal history. Repeated penetrating keratoplasty (PK) is currently the only option for people whose PK graft to treat severe corneal opacity has been rejected. They suggested that using the Boston KPro Type I may mean that people who would otherwise face severe sight loss because of long-term corneal problems or severe corneal damage may able to keep some useful vision. However, they did highlight that visual acuity seems to vary after having the KPro graft, and there is some uncertainty about the long-term benefits. Maintaining or having a modest increase in visual acuity can be important for people with loss of vision to manage their lives independently. They noted that people can find it difficult to care for their corneal grafts appropriately, and it is not yet clear whether eye care after keratoprosthesis with Boston KPro Type I would be any easier.
