Purpose: To report the visual and tomographic outcomes 1 year after porcine collagen lenticule implantation in eyes with advanced keratoconus.
Methods: Patients older than 18 years with advanced keratoconus having central corneal thickness (CCT) greater than 350 µm and visual acuity of 20/40 or better with contact lens, but intolerant to contact lenses, were included. A femtosecond laser-assisted stromal pocket was created at a depth of 140 µm.
