OBJECTIVES: To report the outcomes of patients who underwent Boston type 1 keratoprosthesis (Kpro) surgery at the University Health Network (Toronto, Ont.) and the University of Ottawa Eye Institute (Ottawa, Ont.) between June 2008 and July 2013. DESIGN: Retrospective case series. PARTICIPANTS: Forty-four eyes of 43 patients who underwent Kpro surgery. METHODS: A retrospective review was conducted of all Kpro procedures performed by 4 attending cornea surgeons. The preoperative characteristics and postoperative course of each patient were analyzed. RESULTS: In 31 eyes (70%), the primary indication for a Kpro was failed corneal transplantation. The remaining 13 eyes (30%) had Kpro as a primary procedure. In all eyes, preoperative visual acuity (VA) was 20/150 or worse, with 39 eyes (89%) having a VA of counting fingers, hand movement, or light perception. Mean follow-up time was 21 ± 12 months (range 12-57 months). The retention rate at the last follow-up was 95%. Best-achieved median VA was 20/100 (range 20/20 to no light perception [NLP]), with 37% of patients achieving a VA of >20/40 at some point during their postoperative course. At the last follow-up, median VA was 20/400 (range 20/30 to NLP). The 2 most common complications included retroprosthetic membrane formation (23 eyes, 52%) and elevated intraocular pressure (10 eyes, 23%). There were 5 cases (11%) of stromal melt and 1 case (2%) of infective keratitis. CONCLUSIONS: This study demonstrates that Kpro improves VA in a majority of cases, and is a viable option in situations in which there is a poor prognosis for traditional penetrating keratoplasty.

Palmar and plantar hyperhidrosis is relatively common and can have severe psychological and medical consequences for those afflicted. A multitude of treatments exist but are often inadequate especially for those with significant disease. In these cases botulinum neurotoxin provides a reliable method for reducing the symptoms and improving quality of life. Although actual administration is relatively straightforward, pain management is a crucial component that requires a mastery of several techniques. Patients have a high degree of satisfaction with botulinum neurotoxin treatment and are motivated to come back for repeat treatments, usually every 6 months.
