cal records that I reviewed and received, involving nearly 20 years of office notes and references from multiple glaucoma specialists, the implanted device was described as being a Molteno implant. I therefore requested copies of the original operative report because there was some concern by Dr Molteno that we may be dealing with a counterfeit device. However, to my surprise, I received 2 operative reports. The first describes a Molteno implant being placed in 1996, and the second operative report describes placement of a Krupin valve in 1998, in the same eye. This was the first time I became aware that the patient had 2 implants in the eye. Ever since I have cared for the patient (ie, since October 2011), his affected cornea has been opaque, and the only implant evident on examination is the one that was removed and labeled as "Molteno Implant Functioning as a Culture Plate" (which should be changed to "Krupin Valve Functioning as Culture Plate" 2 ) in the June 2013 issue. 1 I apologize for this error and for my assumption that this was a Molteno implant. I should have checked the appearance of the implant more closely, and if I would have noted the inconsistencies, I would have investigated this prior to publication.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
