ST to Develop and Supply Wireless Sensor for Sensimed's Continuous Eye Pressure Monitor, "Smart" Contact Lens
Known as the Sensimed Triggerfish, the product is based on a "smart" contact lens that uses a tiny embedded strain gauge to monitor the curvature of the eye over a period of about 24 hours, providing valuable disease management data that is not currently obtainable using conventional ophthalmic equipment.
The Sensimed Triggerfish is a two-part system comprised of the smart contact lens and a small receiver worn around the patient's neck. In addition to the strain gauge, the lens contains an antenna, a tiny dedicated processing circuit and an RF transmitter to communicate the measurements to the receiver. The lens is powered via the received radio waves and does not need to be connected to a battery. The embedded components are positioned in the lens in such a way that they do not interfere with the patient's vision. The lens is fitted by the eyecare practitioner and, when the patient returns the next day, the eyecare practitioner removes the lens and receiver, obtaining a complete record of IOP changes over the preceding 24 hours.
The Sensimed Triggerfish has obtained the CE mark and the company is currently running numerous application trials. ST engineers are now working with Sensimed to translate this breakthrough technology into a reliable commercial MEMS product ready for mass production. ST expects the development of the MEMS sensor to be completed in Q2 2010 and manufacturing to start in Q3 2010, with availability outside trials to doctors and patients subject to regulatory approvals. Sensimed and ST anticipate progressively rolling out the product country-by-country across Europe beginning in Q3 and entering the US market by the end of 2011.
BCLA Conference Early Registration Deadline Extended
Among many new features of this year's conference is a rapid-fire session on specialty lenses, chaired by Professor Nathan Efron and Jonathan Walker. Among the topics covered will be advances in lens care solutions and care techniques, multifocals, pediatric lenses, orthokeratology and specialist lens geometry, as well as the latest wavefront designs for asymmetric corneas.
So far, a total of 45 contact lens and contact lens related companies have booked space for the accompanying exhibition, which runs from Friday to Sunday (May 28-30). This year's conference will offer even more opportunities for delegates to hear about the very latest developments from industry and be among the first to handle new products launched at the event. Entry to the exhibition is open to non-delegates as well as registered delegates and is free of charge.
The conference brochure and latest program are available on the BCLA website, www.bcla.org.uk, along with registration and hotel information/reservations.
Thinsite2 Now Offered in More Material Options
Thinsite2 utilizes patented design technology combined with advanced lathing techniques to generate a thinner overall lens profile that reduces lens mass and increases oxygen transmissibility while maintaining lens stability. According to the company, the ultra-thin and light lens profile aids lens centration and promotes healthy lens wear, especially for patients with extreme cases of myopia and hyperopia. By eliminating stress points, Thinsite2 is less prone to lens flexure than other ultra-thin designs, even in lower powered lens parameters. Junctionless front surface technology reduces lens awareness and lid interaction to promote easier, faster adaptation.
Manufactured exclusively by Art Optical, the lens is available in parameters to fit the vast majority of patients. For additional information on Thinsite2, visit www.artoptical.com or contact the Art Optical Customer Care or Consultation team at 800-253-9364.

ACUVUE® Brand Contact Lenses are indicated for vision correction. As with any contact lens, eye problems, including corneal ulcers, can develop. Some wearers may experience mild irritation, itching or discomfort. Lenses should not be prescribed if patients have any eye infection, or experience eye discomfort, excessive tearing, vision changes, redness or other eye problems. Consult the
package insert for complete information. Complete information is also available from VISTAKON®, Division of Johnson & Johnson Vision Care, Inc., by calling 1-800-843-2020 or by visiting jnjvisioncare.com.
HYDRACLEAR® Plus is our brand name for the next generation of our proprietary technology that allows us to use a higher volume of a moisture rich wetting agent in a state of the art formulation. This creates a more wettable, ultra smooth contact lens, especially for challenging environments that make eyes feel dry.

Can-Fite and NIH Apply for a Patent to Treat Uveitis
Can-Fite and the National Eye Institute of the NIH, which collaborate under a Material-Transfer Cooperative Research and Development Agreement, conducted animal studies which demonstrated the efficacy of Can-Fite's lead molecule, CF101, in the treatment of experimental autoimmune uveitis. The submitted patent application protects the use of A3 adenosine receptor agonists for the treatment of Uveitis.
Prof. Pnina Fishman, CEO of Can-Fite, said "The current standard of care for patients with uveitis is steroids and systemic immunosuppressive therapy. The lack of specific drugs for the treatment of this condition creates a need for novel targeted therapies such as the products Can-Fite develops."

Abstract: Ocular Surface Comfort During the Day of Contact and Non-Contact Lens Wearers Assessed by Instant Reporting
More than twenty subjects were recruited per group. Comfort scores were recorded using short message service (text message) in the morning (9:00-11:00 am), afternoon (2:00-4:00 pm), and night (7:00-9:00 pm) using a 0 (causes pain) to 100 (excellent) scale.
The pooled comfort scores across all groups and time periods revealed that data are skewed toward high values: 88% of the scores fell between >or=70 and 100, whereas the remaining 12% fell between >or=40 and <70. Comfort changed significantly over time (P=0.003), but no significant differences were found between groups (P=0.66) or in the interaction between time and group (P=0.79). Hydrogel and silicone-hydrogel contact lens-wearing groups showed similar reductions in afternoon (-4.5 +/- 11.8 and -4.5 +/- 8.6, respectively) and night comfort scores (-8.3 +/- 14.1 and -9.1 +/- 8.7, respectively), and these were greater than those found in gas-permeable and non-contact lens wearers both in the afternoon (-1.0 +/- 11.3 and -1.8 +/- 16.3, respectively) and night (-7.3 +/- 9.7 and -4.1 +/- 21.9, respectively).
Hydrogel and silicone-hydrogel contact lens wearers' comfort scores are reduced at night compared with morning. The authors stated that the slight comfort reduction at night versus morning found in non-contact lens wearers might be related to ocular or general physical fatigue, which suggest the possibility that reduced end-of-day comfort reported by contact lens wearers might not be solely related to contact lens wear. They also concluded that the results of this study also suggest that interpretation of comfort scores should be carried out with caution.
