Sandwich Pk Technique

To present a case of penetrating keratoplasty with a sandwich tecnique.

This is a tecnique to eliminate open-sky time, in patients with high risk of elevated posterior pressure, in order to decrease chance of expulsion of intraocular contents. 

A 45-year-old female patient with a history of corneal perforation in the left eye (light perception) and corneal transplant for keratoconus in the right eye, currently opaque (20/400), presented with a history of pulmonary thromboembolism. General anesthesia was not authorized for this case. A penetrating sandwich keratoplasty technique was chosen to minimize open-sky surgery time, as the patient was under sedation and at high risk of postoperative hemorrhage due to her young age.

Sanwich tecnique is useful tecnique in cases of increased posterior pressure.

This tecnique limits open-sky time during surgery.
