Penetrating keratoplasty is the surgical procedure in which a full thickness of the cornea is removed and replaced with donor tissue, using a microkeratome, which is an instrument employed for removing the cornea or a thin slice of it, creating a thin hinged flap. Penetrating keratoplasty is also used in the treatment of lattice corneal dystrophy. The aim of this eye surgery is to improve visual acuity by replacing the opaque host tissue by clear healthy donor tissue.
