The CorNeat KPro is a novel artificial cornea. Here, we report the results of its implantation into animals, a procedure intended to prove safety and a requirement prior to human trials.CorNeat KPros were implanted in 8 rabbits unilaterally and followed up for 6 months. Upon completion, progressive integrations with no inflammatory rejections were recorded.
Eight male NZW rabbits were subjected to a unilateral intraocular implantation of the CorNeat KPro, while the contralateral eye serves as an untreated control, all under Good Laboratory Practice guidelines.Eight animals were clinically observed for a duration of 6-months to assess safety, during which the eyes are repeatedly monitored by slit-lamp biomicroscopy. At termination, eyes will be enucleated and evaluated histologically.
To date, evidence shows progressive integration and cessation of inflammatory response. Eyes are all intact with no evident breach of integrity or leak of aqueous humor. Animals exhibit use of implanted eyes routinely. Some animals exhibit iatrogenic (surgically induced) Cataract.
The CorNeat KPro device safely integrates into native tissue. Results suggest great potential for its application in a range of human corneal diseases and injuries.
