October 2013 EW CORNEA 59 using a 27-G needle pull-through technique when the tissue has been pulled inside the eye it unfolds stromal side up and endothelium side down so that the chance of having the graft unfold upside down is unlikely. In addition, the ability to insert the tissue with a low anterior chamber infusion allows the eye to remain pressurized throughout the insertion and unfolding maneuvers. The use of a bent 27-G needle in combination with the Busin glide for insertion of the posterior lamellar graft into the anterior chamber in a pull-through technique from a nasal paracentesis is a simple improvement on the traditional Busin glide technique; the needle avoids the use of expensive forceps and allows the surgeon to insert, center, unfold, and fixate the graft to the recipient cornea with air injection using only one maneuver.

THINK PATIENT SAFETY "LENSAR's cluster of imaging technologies makes it possible to precisely image the exact location and contour of the posterior capsule, which is the 'Holy Grail' for performing safe ReLACS." – Kerry Assil, MD 12. Khor WB, Teo KY, Mehta JS, et al. Descemet stripping automated endothelial keratoplasty in complex eyes: Results with a donor insertion device. Cornea 2013; Feb 26. continued on page 60 At LENSAR™, we're always thinking ahead. That's why we designed the LENSAR Laser System with your patients' safety in mind. The Augmented Reality™ rotating camera captures 10 images from the anterior cornea to the posterior capsule and reconstructs a 3-D model of the eye. Because you'll see exactly where the relevant anatomy is in the eye for all grades of white or brunescent cataracts, you can feel secure in designing an optimum treatment that will maximize outcomes without putting your patients at risk.
