Alcon said that results from a new non-interventional study showed that its Clareon monofocal intraocular lenses (IOLs) and TECNIS Eyhance monofocal IOLs offer a similar range of vision.

The comparative study was taken up to assess visual outcomes in subjects implanted with bilateral Clareon monofocal IOLs compared to bilateral Eyhance monofocal/toric IOLs.

A total of 620 eyes of 310 cataract patients were evaluated in the US, of which 155 were implanted with Clareon and 155 with Eyhance. The participants had successful, uncomplicated cataract surgery at least three months before the study and had post-operative best-corrected distance visual acuity of 20/25 or better after removal of cataract.

According to Alcon, the best-corrected distance acuity in eyes which wore Clareon (0.01 logMAR) was identical to best-corrected distance acuity with Eyhance (0.02 logMAR).

Distance-corrected intermediate acuity was almost the same in both arms with a mean difference of 2.5 letters.

Alcon said that the study showed that there was extreme similarity in the binocular defocus curves from +1.00 D to -3.00 D, which further demonstrated an identical range of vision for the two monofocal IOLs.

The findings of the investigator-initiated study led by J. Morgan Micheletti were presented at the annual meeting of the American Society of Cataract and Refractive Surgery (ASCRS) taking place in San Diego, California.

Alcon vice president and US surgical franchise general manager Jim Di Filippo said: “At Alcon, research is the foundation for how we improve lives, and it goes beyond R&D—we also support real-world studies after our products move to market.

“We’re extremely proud of the innovation behind Clareon, our latest IOL material, which has now been implanted in more than three million people worldwide—and delivers on our promise of exceptional clarity with the real-world outcomes doctors and patients expect from Alcon.”

The eye care company Alcon launched the Clareon family of intraocular lenses in the US around this time last year. The family of IOLs includes the Clareon Aspheric Hydrophobic Acrylic and Clareon Aspheric Toric IOLs, the Clareon PanOptix Toric, Clareon PanOptix Trifocal Hydrophobic IOL, Clareon Vivity Extended Vision Hydrophobic Posterior Chamber IOL and Clareon Vivity Toric IOLs.
