David Hutton:

I'm David Hutton of Ophthalmology Times. Hawaiian Eye is being held this year at the Grand Wailea resort in Maui. Joining me today is Dr. Eric Donnenfeld. Who is presenting "Small Aperture IOL for Irregular Corneas." Thanks so much for joining us today. Tell us about your presentation.

Eric Donnenfeld, MD:

Well, first of all, David, thanks for having me here today. I'm talking about a novel lens, the IC-8 Apthera lens, which is a small aperture wavefront-filtering lens. And the question is, where does it fit in my practice? Well, for regular corneas, it works very well for monovision candidates, people with less cylinder, upgrading a patient who might normally choose a monofocal. But where I really find this successful is in irregular corneas. I use it for patients who have central clear corneas.

For example a patient who's post LASIK, particularly hyperopic LASIK that just aren't good candidates for trifocals because of their irregular corneas. And these are patients who want additional near but don't want to have the glare disability of a trifocal in a regular cornea. I also love it for more complex eyes, eyes that have less quality vision.

So these are patients who have eyes like post parquet or post transplant or mild keratoconus where I find it very helpful. For me the low hanging fruit again are post PK, RK, corneal scars, keratoconus. What's nice about the lens it's very forgiving, it'll forgive up 2.75 diopters of sphere at 1.5 diopters of cylinder. So this is a lens which is an important part of my toolbox in managing patients with irregular corneas and I find it really extraordinarily helpful and gives best in class results for patients who otherwise would not be candidates for conventional cataract surgery.
