Video demonstrates the "V" sign during penetrating keratoplasty. The "V" sign occurs when the needle passes at 99% depth on the host cornea. Because descemet's membrane is elastic, it travels with the needle forming a V until the suture is passed and the V is released. Observing the V during surgery ensures that one is a the correct depth when passing sutures during corneal transplantation.
Thank you so much for posting. However, I don't hear any sound on this video and I can't see the V sign. Could you please put an arrow on the video to show the v?
