I'm curious as to whether anyone has had any experience with this device/lens and what your opinions are about it.Chris Ryser said:
FDA APPROVES AUTOFOCUS LENSES
Eyeonics has received FDA approval for its first U.S. product, the Crystalens, an accommodating intraocular lens that allows patients to focus automatically at all distances.
According to the company, Crystalens is implanted during cataract surgery and accommodates like the eye's natural lens, allowing for clear vision without additional aids. Standard intraocular lenses restore only distance vision, with many patients still requiring glasses or contact lens to make up for other deficiencies.
Thanks,
Diane
Anything worth doing is worth doing well.

Prototype computer allows blind to see
19 Mar 2004
Prototype system developed by Wright State computer engineer allows blind to “see”.
Researchers at Wright State University have developed a prototype device to help blind individuals “see.”
Nikolaos Bourbakis, Ph.D., Ohio Board of Regents Distinguished Professor of Information Technology at Wright State’s College of Engineering and Computer Science is the principal investigator. The project is a cooperative venture with Arizona State University (ASU).
“Our object is to develop intelligent assistants that can help blind and visually impaired individuals efficiently conduct daily tasks, such as reading a book or newspaper and efficiently accessing the Web and participating in classes,” explained Bourbakis, who has been involved in computer engineering eye research for 20 years.
Tyflos, the Greek word for blind, is the name of the portable, wearable device Bourbakis has developed. The partnering project at ASU is called iLearn. A tiny camera is mounted to glasses and connected by a thin wire to a modified lap-top computer the individual carries on his or her back.
The Tyflos system operates by identifying the images “seen” by the camera and converting this to audio information the subject hears from small wires connected from the backpack to the ear. A small microphone is attached for receiving commands or requests from the user.
Bourbakis, who started on this project in 1995, plans to work with the WSU Office of Disability Services to test the device’s capabilities on visually impaired students.
In addition, he is working on an extension of the Tyflos system that enables blind individuals to independently navigate their working and living environments.
Two future extensions of the Tyflos system will offer writing and drawing assistance that will enable the visually impaired to visually express their artistic talent beyond the usual levels.
“The Tyflos camera captures images from the surroundings, and the portable computer reconstructs the 3D space for motion detection, body tracing, face recognition and moving objects,” explained Bourbakis, who also directs the Information Technology Research Institute and the Assistive Technology Research Laboratory at Wright State.
“This will make it possible for the blind and vision impaired to improve their independent mobility and social interaction, while succeeding in their professional endeavors. It is a great feeling for visually impaired people to make the first call in a conversation, like hi John, rather than waiting for somebody to talk to them. We are using state-of-the-art computer vision and robotics technology that will help the users tremendously in recognizing faces, objects, reading books, surfing the Web and safely navigating in dynamic environments.”
He said the applications of the project are substantial, with an estimated 45 million blind individuals in the world, according to a World Health Report.
Funding for the project includes a $1.1 million National Science Foundation grant to ASU and Wright State. This was awarded last fall for four years.

FDA SET TO APPROVE PRESBYOPIA TREATMENT
Refractec is set to announce that it has received FDA approval to market a procedure that uses radio-frequency energy to treat presbyopia, the close-vision problem that afflicts most adults by age 50.
The procedure — conductive keratoplasty — uses radio waves to reshape the cornea and bring near vision back into focus.
FDA APPROVES NEW LABEL CLAIMS FOR LENS IMPLANT

'LASER VISION' OFFERS NEW INSIGHTS
A system that projects light beams directly into the eye could change the way we see the world. US firm Microvision has developed a system that projects lasers onto the retina, allowing users to view images on top of their normal field of vision. It could allow surgeons to get a bird's eye view of the innards of a patient, offer military units in the field a view of the entire battlefield and provide mechanics with a simulation of the inside of a car's engine.

ADVANCED MEDICAL OPTICS: LICENSING AGREEMENT WITH QUEST VISION
Advanced Medical Optics (AMO), developer, manufacturer, and marketer of ophthalmic surgical and eye care products, announced a one-year research and evaluation licensing agreement with Quest Vision (QV), a California-based research and development company, to develop accommodating intraocular lens (IOL) designs, which will give AMO a minority interest in QV with an option to purchase the company after one year.
The accommodating IOL designs are being developed to address presbyopia, the progressive loss of the natural lens' ability to change focus from far to near objects caused by the aging of the eye's natural lens, by mimicking the qualities of the eye's natural crystalline lens by accommodating in response to changes in the eye's natural ciliary muscle mechanism.
Under the agreement, AMO will have access to a number of issued and pending patents for various design approaches that encompass both axial movement and shape-changing technology. No other terms of the agreement were disclosed.
AcrySof(R) ReSTOR(R) Intraocular Lens Demonstrates Ability to Provide Excellent Near and Distance Vision After Cataract RemovalPR Newswire - Monday, May 03, 2004
- Surgeons present data on IOL at ASCRS meeting FORT WORTH, Texas, May 3, 2004 /PRNewswire-FirstCall via COMTEX/ -- Alcon, Inc. (NYSE: ACL) reported updated clinical results on the AcrySof(R) ReSTOR(R) intraocular lens (IOL) that demonstrate its ability to substantially restore a cataract patient's ability to see both near and distant objects without the aid of reading glasses or bifocals. Today, the vast majority of patients who undergo cataract surgery receive monofocal IOLs, which typically require them to carry around reading glasses so they can read a newspaper, menu or medicine bottle, or do other things that require close vision such as sewing, building models and playing cards.
"These data are extremely promising, considering our nation's dependence on reading glasses and bifocals to see near objects in general and especially following cataract surgery," said James A. Davison, MD, FACS, of Marshalltown, IA, an investigator in the study, who presented Phase III study data at the American Society of Cataract and Refractive Surgery (ASCRS) annual symposium in San Diego. Dr. Davison added, "I believe the AcrySof(R) ReSTOR(R) lens will greatly improve quality of life for the vast majority of patients who receive it by eliminating or greatly reducing their dependence on reading glasses after surgery."
The AcrySof(R) ReSTOR(R) IOL represents breakthrough technology because it delivers consistent high-quality pseudoaccommodative vision across the entire visual spectrum due to the unique, proprietary and innovative optics of the lens, rather than relying on unpredictable and variable mechanical processes to achieve accommodation. This lens achieved CE mark status April 4, 2003 and is currently being implanted in patients outside the U.S. The Pre-market Approval application has been submitted to the FDA and Alcon anticipates this technology will be available in the U.S. in 2005.
"Based on the response by doctors and patients outside the U.S., we believe AcrySof(R) ReSTOR(R) will have a positive impact on our sales of IOLs," said Cary Rayment, Senior Vice President, Alcon United States. "Reducing the need for reading glasses after lens removal, without compromising distance vision, has been a goal of ophthalmology for many years, and it looks like the range of accommodative effect and predictability of this lens may finally get us there."
Study Methods and Results
Multi-center clinical studies were conducted in the United States and Europe to establish the safety and effectiveness of the AcrySof(R) ReSTOR(R) IOL. A total of 566 patients received the AcrySof(R) ReSTOR(R) IOL and 194 received the AcrySof(R) monofocal IOL as a control. The mean age for the total population was 69 years. In the study, 99 percent of patients who received the AcrySof(R) ReSTOR(R) and 98 percent of patients who received the monofocal IOL achieved distance visual acuity of 20/40 or better, without correction by contacts or glasses, with both groups exceeding the FDA grid value of 92 percent for this measurement. Furthermore, 88 percent of patients who received the AcrySof(R) ReSTOR(R) IOL achieved distance visual acuity of 20/25 or better without correction by contacts or glasses compared to 92 percent for the monofocal control group, reflecting that the two lenses were statistically equivalent at this level of distance visual acuity.
As for near vision, following bilateral implantation (implantation in both eyes), 74 percent of patients receiving the AcrySof(R) ReSTOR(R) achieved near visual acuity of 20/25 (J1) or better without correction by contacts or glasses, while only 14 percent of the monofocal control group achieved this level. In addition, 85 percent of the AcrySof(R) ReSTOR(R) IOL patients achieved functional binocular uncorrected intermediate vision (20/40 or better (J3) measured at standard 60 cm computer screen working distance) compared to 67 percent of monofocal control patients. J1 means patients can read the very small stock quotes in the newspaper, while J3 means patients can read the normal newspaper type size.
This exceptional visual performance was independent of pupil size and was accomplished by the optics of the lens without physical movement of the lens inside the eye, making visual outcomes highly predictable. As a result, 80 percent of AcrySof(R) ReSTOR(R) patients reported never using glasses for either near or distance vision, compared to only 8 percent of the monofocal control patients. This is the first time this level of spectacle independence has been achieved.
Contrast Sensitivity
Contrast sensitivity data presented at this meeting indicated that at lower spatial frequencies there was no clinically or functionally significant difference between AcrySof(R) ReSTOR(R) and monofocal control subjects. Other studies indicate that these lower spatial frequencies are most important in terms of vision related to everyday life skills, such as walking, driving, and reading.
About AcrySof(R) ReSTOR(R) IOL
The AcrySof(R) ReSTOR(R) IOL is a foldable intraocular lens. Its unique apodized diffractive optic design provides pseudoaccommodation, which is the ability of a lens to focus light correctly on the retina for images at various distances without mechanical movement of the lens. This optic design results in highly-predictable visual acuity results, thus allowing a patient to experience reduced dependence on glasses or contacts for their daily requirements for near, intermediate and distance vision. The AcrySof(R) ReSTOR(R) IOL is made of the same highly-biocompatible acrylic material as Alcon's market-leading AcrySof(R) family of intraocular lenses, which have been implanted in more than 17 million human eyes since 1991. The new IOL is particularly well-suited for patients who wish to reduce their dependency on eye glasses once their lens is removed, as occurs in cataract surgery.
