An eye cup is placed over the eye and the solution is placed in in the cup Marajan Nabili Aditi Shenoy et al. Ultrasound-enhanced ocular delivery of dexamethasome sodium phosphate: an in vivo study

6. Drug Delivery Cont. In this case the transducer is set to 400 Hz and 600Hz. This makes dealing with illnesses with the eyes easier to treat. This study proved that it can work but needs much more testing. As of right now there are serious risk of doing this procedure.

7. Discussion Ultrasounds have come a very long way over the years. They can be used in a number of medical procedures. It can be used for pregnancies, injections, and now even drug delivery. There has been great use for this technology and new discoveries are being made.
