Abstract

Systems and methods employ bioresorbable corneal implants to treat corneal ectatic disorders and/or refractive errors. The corneal implants may be formed from a porous microstructure that can encourage the proliferation of endogenous keratocytes. As such, the corneal implants act as tissue scaffolds that promote tissue growth to increase the biomechanical stability and/or change the shape of the cornea. Over time, the corneal implants may resorb via hydrolysis or enzymatic breakdown, negating the risks of inflammation, scarring, or foreign body response. The corneal implants may also employ drug coating(s) to promote tissue growth.
