Better vision results obtained with iDesign platform

Patients who underwent refractive surgery with the iDesign platform had better uncorrected distance vision and a better chance of achieving 20/20 vision compared with those who underwent treatment with the WaveScan system.
“iDesign gave me a higher percentage of patients who are 20/20 or better in each eye than the WaveScan over the course of several thousand patients with each technology,” Lloyd Williams, MD, PhD, told Healio/OSN, discussing a presentation he gave during the American Society of Cataract and Refractive Surgery meeting. “Not only did we find better results with iDesign, but we found it easier to use because the way the data capture takes place was easier to use for our technicians, and we also found that the iris registration and some of the technical things that take place during surgery made it more reliable and easier to use.”
Williams and colleagues conducted a retrospective chart review of a single center and surgeon. Patients who underwent LASIK or PRK between September 2013 and July 2019 were included. Postoperative outcome measures were obtained at 3 months and 12 months; 2,044 eyes received WaveScan treatment, and 1,320 eyes received iDesign treatment (both Johnson & Johnson Vision).
At 3 months, 87.7% of WaveScan patients had 20/20 or better vision, while 94.1% of iDesign patients had 20/20 or better vision (P < .001). At 12 months, 88.5% of WaveScan patients and 95.4% of iDesign patients had 20/20 or better vision (P < .001).
“You should feel comfortable exchanging your WaveScan for an iDesign, if you’re still using WaveScan,” Williams said. “In fact, not only should you feel comfortable, but I would feel uncomfortable not exchanging them because I think iDesign is clearly the superior technology, and I want to give my patients the best technology I can.”
