Human penetrating keratoplasty using modified M-K medium

Ophthalmic Surgery
S R Waltman, P F Palmberg


Preservation of donor tissue for human keratoplasty has been evaluated using modified M-K medium. The medium has been modified by changing the antibiotic and buffer and adding a pH indicator. These changes offered theoretical and practical advantages. There were no primary donor failures in 50 consecutive penetrating keratoplasties with an overall success rate of 92 percent. Clinical specular microscopy revealed good endothelial cell survival.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
