Agreement Provides Worldwide Commercial Rights to New IOL Designs for enVista® IOLs

BRIDGEWATER, N.J., Oct. 1, 2019 – Bausch + Lomb, a leading global eye health company, today announced that it has entered into a licensing agreement with Tatvum Research, a company focused on intraocular lens (IOL) development and design. The agreement provides Bausch + Lomb with worldwide commercial rights to new IOL designs for enVista® IOLs that will address astigmatism and presbyopia.

“This agreement is part of our continued investment in expanding and improving upon our IOL options for our customers and their patients” said Chuck Hess, vice president and general manager, U.S. Surgical, Bausch + Lomb. “We look forward to applying these innovative designs on our rapidly growing enVista IOLs.”

When available, these new advanced enVista IOLs, developed in partnership by the two companies, will include a series of intraocular lenses that will correct for astigmatism and presbyopia, featuring an enhanced range of vision. Bausch + Lomb anticipates filing for regulatory approval of the lenses over the next several years.

“As a company that has consistently demonstrated innovation leadership and a commitment to bringing new technologies to the market, Bausch + Lomb makes an ideal partner for us,” said Nivedan Tiwari, partner, Tatvum Research. “We are confident that by working together with the optical engineers at Bausch + Lomb, we will create a range of new IOLs that significantly expand the capabilities of surgeons who want to provide the best possible quality of vision to their patients.”

About enVista® IOLs
The enVista® family of lenses, which include monofocal and toric IOLs, remain the only single-piece, hydrophobic acrylic lenses domestically available that have been proven to be glistening-free.1 They feature a unique set of features that help compensate for the eye’s natural imperfections. The Trusight™ aspheric optic provides the benefits of excellent image quality and depth of field, as well the potential for increased resistance to scratches and abrasions that may occur during loading and surgical manipulation. Step-vaulted AccuSet™ haptics allow for extensive interaction with the capsular bag to aid in securing the lens position. The SureEdge™ design features a continuous 360-degree square edge, which potentially prevents posterior capsular opacification (PCO) compared to round edge designs.2,3,4 StableFlex™ technology provides improved material properties to deliver enhanced optic recovery following delivery.

About Tatvum
Tatvum is focused on developing and licensing technologies and novel ideas for IOL designs and innovative software applications, including Artificial Intelligence Systems and Visual Disturbance Evaluation Tools, with the goal helping surgeons optimize patients’ clinical outcomes.
