How to insert with a dental ring or o ring

To insert your scleral lens with a dental ring or o-ring, place the ring on one finger. Then, place the scleral lens on top of the ring. This will allow your other fingers to be used to control your lower eyelid. Next, fill the lens with non-preserved saline. Then, use your other hand to control your upper eyelid. Apply the lens with a swift motion.
