WAIKOLOA, Hawaii — John A. Hovanesian, MD, FACS, presented his pearls for intraoperative aberrometry usage here at Hawaiian Eye.
“While intraoperative aberrometry is a highly valuable tool, we have to know what it can do, and we have to know what it cannot do. We have to know what it is designed to do, which is take in all the information that you have given it (even if some of it is flawed) and take us in a direction that we do not want to go,” he said.

Physicians should take the time to learn the instrument that they are using, he said.
“The more time you spending learning the controls in the beginning and not let the trainer touch the control panel or the machine at all, the more you and your staff are going to learn the strengths and weaknesses of the instrument. There are all kinds of things that we have to be aware of,” Hovanesian said.
Intraoperative aberrometry devices show real-time measurements at the top of the screen, and physicians should be aware of that, he said.
“Pay close attention to intraocular pressure. You are going to get a sense of your comfort and confidence in the measurements you are getting before you finally click the button to capture,” Hovanesian said.
Hovanesian noted that it is not valuable to chase after small amounts of cylinder particularly if the physician has taken a pseudophakic measurement, and the patient has a 0.5 D or less of astigmatism with a shifting axis.
Physicians should look for something that is not immediately available in the operating room, he said.
“I have learned that my ORA [System] is my most trusted advanced diagnostics tool that I have for advanced cataract,” he said. “I have also learned to respect the learning curve, and I encourage you to do this so [the ORA System] becomes a tool for you and not just an absolute answer”– by Nhu Te
