Tecnis Eyhance leads to good visual and refractive outcomes in post-refractive surgery eyes
At the American Society of Cataract and Refractive Surgery Annual Meeting, Abinaya Thenappan, MD, of the Cleveland Eye Clinic, spoke with Ophthalmology 360 about the Tecnis Eyhance and found it was a “strong candidate” for post-refractive eyes.
Abinaya Thenappan, MD:
Hi, my name is Abinaya Thenappan. I’m a cataract and refractive fellow with Dr. Wiley and Dr. Bafna at the Cleveland Eye Clinic. I’m here to share a little bit about our results, our experience using the Tecnis Eyhance in post-refractive eyes. As we know, patients who have had a history of refractive surgery are often very motivated to regain their spectacle independence after cataract surgery. The power calculations can be a little bit tricky in these eyes, and enhancement rates can vary widely, anywhere from 4% to 50% depending on the study.
One lens that is of particular interest in this population is the Tecnis Eyhance for a couple of reasons. One, it has a small central add power that theoretically increases the depth of focus and offers a wider landing strip, if you will. It also has negative spherical aberration, which counteracts the positive spherical aberration that is seen in post-myopic LASIK and RK eyes, corneas. Theoretically, the Tecnis Eyhance is a very strong candidate in these post-refractive eyes for these 2 reasons. It has a little bit better visual optical quality theoretically, and more refractive forgiveness. What we did to test this is we looked at 339 eyes of 227 patients that had a history of refractive surgery and subsequently underwent Eyhance implantation. This was a retrospective review of consecutive case records from our clinic.
What we found was, at postop month 1, 89% of them had achieved an uncorrected visual acuity of 20/30 or better. By postop month 3, 91% of them had achieved a corrected distance visual acuity of 20/30 or better. Our enhancement rate was 1.2% overall, and the mean spherical equivalent that these eyes landed at was 72% of them were about plus minus half the diopter. Overall, these early outcomes suggest that the Tecnis Eyhance is a strong candidate in these post-refractive eyes. It offers a level of refractive forgiveness that is very valuable in these eyes. Moving forward, we’re hoping to compare this to a group of post-refractive eyes that received a standard Tecnis monofocal to see how they compare.
Of course, there are some limitations with the study, as with any study. We didn’t have very long follow-up. We also didn’t compare to a standard monofocal yet. We don’t have that data quite yet, and it would have been nice to have some sort of wavefront analysis or contrast sensitivity. These are some future directions that we’re brainstorming, but overall, we’re excited with our initial results and excited to share them with you.
