Downward viewing common-path optical coherence tomography guided hydro-dissection needle for DALK

Abstract

Deep anterior lamellar keratoplasty (DALK) using a “Big Bubble” technique requires precision insertion of a dissection needle into paracentral corneal stroma for air/fluid injection. We designed and built a downward viewing common-path optical coherence tomography (OCT) for guiding the hydro-dissection needle. The system was tested using rabbit cornea disks and the results showed that the downward distal sensor can accurately detect the needle tip position relative to Descemet’s membrane during the insertion.
