FDA approves CyPass Micro-Stent

The CyPass® Micro-Stent is a minimally invasive device that can be implanted at the time of cataract surgery. About 20% of patients undergoing cataract surgery also have glaucoma, leading to a large number of patients who could conveniently receive combined therapy.

FDA has approved CyPass micro stent from Alcon Laboratories.

FDA Approves Extended Depth of Focus Lenses for People with Cataracts

Abbott announced today that the U.S. Food and Drug Administration (FDA) has approved the Tecnis Symfony® Intraocular Lenses for the treatment of cataracts. The first in a new category of intraocular lenses (IOLs), the Tecnis Symfony lenses are the only lenses in the United States that provide a full range of continuous high-quality vision following cataract surgery, while also mitigating the effects of presbyopia by helping people focus on near objects. The FDA approval includes a version of the lens for people with astigmatism, the Tecnis Symfony Toric IOL.



Cataracts are a common condition, with almost 4 million cataract surgeries performed each year, and that number is expected to increase.1 By age 80, more than half of all Americans either have a cataract or have had cataract surgery.2 However, cataracts do not just impact seniors. In 2016 it is estimated that nearly one in four cataract surgeries will be performed on people younger than 65.1 Many people who have cataracts experience other problems with their vision, such as presbyopia and astigmatism, which the Symfony lenses also address. Presbyopia, which affects most people over age 40, means people have lost the ability to focus on objects up close and often require glasses to perform near visual tasks. Astigmatism is when the cornea is misshapen, which causes blurry or distorted vision.

"The Symfony intraocular lens is a new option I can offer my patients to improve their vision following cataract surgery, especially those who have difficulty focusing on objects at near distances because of presbyopia," said Eric D. Donnenfeld, M.D., of Ophthalmic Consultants of Long Island, New York. "Many of my patients live very active lifestyles and want to see clearly at all distances, and without glasses if possible. With the Symfony lens, I can give patients the freedom to enjoy the activities that matter to them, while wearing glasses less."

During cataract surgery, the natural lens of the eye is removed, and an artificial lens, called an intraocular lens, or IOL, is inserted into the eye. The IOL most commonly used in cataract surgery is a monofocal lens, which only allows the person to see at a distance, with closer objects being out of focus. In contrast, the Symfony lens was specifically developed with features to improve both the range and quality of vision.

"Abbott is focused on improving people's vision and their lives by helping them stay healthy and active. Symfony offers patients, including those with astigmatism, an option for crisp, clear vision at all distances," said Thomas Frinzi, senior vice president of Abbott's vision business. "This is an important addition to our portfolio of lenses, as we expect many patients to choose a Symfony lens over a standard monofocal lens, given its benefits. We are happy that we can offer more people around the world this new category of lenses."

The approval was based on results of a U.S. pivotal study that compared the Tecnis Symfony lens to a Tecnis aspheric monofocal lens in 298 patients. Compared with patients in the monofocal group, those who received a Tecnis Symfony IOL achieved greater improvements in intermediate and near vision while maintaining similar distance vision. Patients in the Symfony group were also more likely to achieve reduced overall spectacle wear and high overall visual performance in any lighting condition. Rates of adverse events did not differ between the Symfony and monofocal groups.

The Symfony lens is approved in more than 50 countries around the world, and has been widely studied, with data from numerous clinical studies involving over 2,000 eyes. In clinical studies, the Symfony lens:
Provided seamless, day-to-night vision. Patients could see objects sharply and clearly at near, intermediate and far away distances, and points in between.
Provided high-quality vision. Some IOLs may leave patients with an inability to focus clearly due to competing wavelengths of light passing through the lens at different angles (known as chromatic aberration), or with vision that is not completely focused because of the shape of the lens (known as spherical aberration). The Symfony lens has been engineered to correct these issues.
Demonstrated a low incidence of halo and glare, which may be perceived as rings or blurring around bright lights. Glare and halo can sometimes affect an individual's ability to drive at night or to perform other visual tasks.

Bausch Lomb & IBM to work on cataract surgery APP on IBM Cloud

Bausch + Lomb announced a collaboration to develop the first app of its kind for iPhone and iPad for surgeons who perform cataract surgery. The innovative app will help surgeons streamline their workflow by delivering patient information and clinical insights as well as intraocular lens (IOL) options on a single, digital platform at the point of care.

than 22 million Americans and that number is expected to rise to 30 million by 2020 . Cataracts – a clouding of the eye’s lens that can lead to blindness if untreated – affect approximately 70 percent of people by age 75 . In cataract surgery, the cloudy lens is removed and replaced with an artificial lens – an IOL.

Today, many cataract surgeons consult patient data in the operating room (OR) via print-outs or notes created during pre-op patient office visits, which can often be bothersome and inefficient. The new app from Bausch + Lomb will be designed to provide surgeons with access to information that

patients have agreed to share, enabling doctors to plan their surgical interventions -- including IOL selection -- and have the option to view the information on digital devices or display screens on walls in the operating room during surgery.

The app will be designed to electronically manage patient data across iPhone and iPad while hosting health-related data on IBM Cloud Platform, Bluemix -- a security rich, cloud-based environment -- and relaying customized IOL options to surgeons that they will use to help enhance surgical

planning and provide better patient care. The MobileFirst for iOS team, which is part of IBM Global Business Services, will design and develop this custom app for Bausch + Lomb to help drive innovation in healthcare. Bausch + Lomb’s vision is to optimize the app to collect data over time, resulting in a cognitive app that applies machine-based learning and predictive analytics to deliver real-time insights to surgeons.

By compiling each cataract patient’s information in the app -- including IOL calculations, corneal topography and other biometry results as well as lifestyle preferences -- surgeons and their staff may generate a comprehensive, integrated profile to help them facilitate IOL selection and procedure

planning. Historical surgical data and other patient insights can also be housed within the app to potentially support positive clinical outcomes for future cataract.
