Corneal wedge resection to treat progressive keratoconus in the host cornea after penetrating keratoplasty

J Cataract Refract Surg. 2003 Feb;29(2):395-401. doi: 10.1016/s0886-3350(02)01487-6.


We present 3 cases of progressive keratoconus in the host after penetrating keratoplasty PKP that were treated with a wide crescentic excision of the diseased tissue in the host cornea guided by Orbscan II topography (Bausch & Lomb). In all cases, the procedure resulted in a more regular corneal shape with a marked reduction in astigmatism, preventing the need for repeat PKP
