Surgeon: Intraoperative aberrometry ‘a step closer to LASIK-like outcomes’

WAILEA, Hawaii — A speaker discussed his pearls on the use of intraoperative aberrometry here at the Hawaiian Eye 2015 meeting.
The benefits of intraoperative aberrometry are that the system helps confirm IOL power, has continuous display of refractive data and is a step closer to LASIK-like outcomes for cataract surgery, Sumit “Sam” Garg, MD, said.

When using intraoperative aberrometry for the first time, Garg recommends surgeons to start with normal eyes, make sure the cornea is clear, fill eye with viscoelastic and initially use Barraquer tonometer (Ocular Instruments).
“I do recommend using the Barraquer tonometer to get a sense for where you want the pressure to be – around 25. After you do that, I think you can use your finger for palpation. It works pretty well,” Garg said.
For toric alignment, Garg relies on aphakic readings and uses the Optiwave Refractive Analysis (ORA) System with VerifEye (Alcon Laboratories).
“I use the VerifEye in the phakic setting to look at where the steep axis is prior to my incision preoperatively before I do anything to the eye without actually catching a measurement and it will tell you where the steep axis so you can put your incision there,” Garg said.
Garg also recommends that surgeons take multiple measurements and make sure the surface is dry. –
