Dr. Mitchell Weikert on Cassini after comparison study with Scheimplug and other topographers for IOL surgery and cataract surgery.
We've compared Cassini
for IOL placement in cataract surgery."
"We've been comparing the Cassini with Placido ring and Scheimpflug to see where it excels, if and where there are any disagreements and why, and which one is right," says Dr. Weikert.
So far, having imaged a couple of hundred patients, he
is impressed with the Cassini
is running studies comparing the effectiveness of the Cassini's
in imaging the cornea for IOL placement in cataract surgery.
One study by Dr. Weikert
compared the Cassini's
measurements of corneal curvature, astigmatism, and aberrations in both normal eyes and eyes with prior laser refractive surgery with those produced by a Humphrey Atlas and a Galilei combined Placido-Scheimpflug device.
The findings were presented at the American Society of Cataract and Refractive Surgery
"We found very good agreement between the devices, especially in normal eyes, and only a little disagreement in the pattern in eyes that had had prior refractive surgery, so I think the Cassini
shows promise," comments Dr. Weikert
"All current measurement techniques fall short, so there is plenty of potential to improve and we are hopeful that the Cassini
will help us do that.
And as far as aberrations go, the Cassini
does a very good job at measuring them."
Indeed, Dr. Weikert
sees a lot more potential in the Cassini's
ability to measure discrete points.
One example he
gives is non-circular aberrations.
