"Today's patients with cataracts not only want clear vision, but also less dependence on glasses following surgery—something that has historically been challenging to deliver for those with astigmatism," said Daniel H. Chang, M.D., Cataract and Refractive Surgeon at Empire Eye & Laser Center. "In my experience, toric IOLs can produce excellent visual outcomes, however, even small misalignments of the lens can lead to blurred vision. I'm looking forward to being part of the post-market clinical trials to further evaluate the rotational stability of TECNIS Toric II IOL in a large population of patients."
Astigmatism is highly prevalent, affecting nearly half of the 24.4 million cataract patients in the U.S., yet it often goes untreated during cataract surgery.2 Toric IOLs are the most predictable method for correction, however, surgeon concerns around rotational stability may be acting as a barrier to providing treatment.3 Properly implanting a toric IOL can be more challenging than a conventional spherical IOL due to the high degree of precision required to align the lens properly in order to correct the astigmatism present in the eye.4 Movement of the lens after implantation can result in decreased vision and the need for realignment.
"With the launch of TECNIS Toric II IOL, our goal is to provide surgeons with a higher degree of confidence in treating astigmatism so that more cataract patients can enjoy clear, high quality vision," said Xiao-Yu Song, Global Head of Research & Development, Johnson & Johnson Vision. "This advance represents the latest addition to our TECNIS Family of IOLs, building on our proud history of raising the standard of care for patients with cataracts."
