White Ring Sign during SMILE

In this 1-Minute Video, Dr. Ashvin Agarwal discusses the significance of the white ring sign during SMILE procedures. It is important to denote the plane of dissection after laser, especially as the incision size reduces. The white ring sign—originally described by Dr. Soosan Jacob—is a deflection that can be seen on the lenticular cut side when the dissection rod lifts the lenticule. Ideally, the sign should always be present during posterior dissection but never during anterior dissection.
