Abstract Details

Purpose:

To describe the results of our experience both in best-corrected visual acuity (BCVA) and in complications of Boston Type 1 keratoprosthesis (BKpro1) implant.

Setting:

University Hospital Complex of Albacete. Albacete. Spain.

Methods:

We reviewed BKpro1 surgical procedures, from clinical records, from 2010 up to today. A total of five BKpro1 were implanted into 5 eyes of 5 patients. Common preoperative diagnoses were corneal limbal stem cell failure caused by graft failure in 3 (60%) of them and chemical injury in the remaining patients (40%). The mean preoperative BCVA on the logMAR scale was 2.3 while the postoperative BCVA was 0.39 (0.56 on a decimal scale).

Results:

The most common complications were retroprosthetic membrane formation (RMF) and high intraocular pressures (IOPs). The RMF appeared in 2 eyes (40%) and was treated with YAG laser membranotomy. IOP also appeared in 3 cases (60%) and was controlled by topical hypotensive medications, except in one patient that required Ahmed valve surgical implant. We found no infectious complications in any of the 5 cases. However, an epiretinal membrane (ERM) did appear in one eye that was treated by vitrectomy and membrane peeling.

Conclusions:

BKpro1 improves visual function in patients with multiple failed corneal grafts and poor visual acuity in the other eye at the expense of non-serious complications.
