Borish Biography
William Balwdin, O.D., has penned a biography of Dr. Irvin M. Borish, O.D., titled “Borish,” that explores the private and professional life
of the clinician/researcher/inventor/educator/philanthropist. Dr. Borish played a key role in the founding of Indiana University School of Optometry and was the first
optometrist voted into the National Optometry Hall of Fame.
Obtain a copy of the book with Dr. Borish’s signature and a
greeting at http://www.opt.indiana.edu/bcor/borishbook/index.htm. You can also meet Drs. Baldwin and
Borish at this year’s SECO meeting in Atlanta to acquire an autographed copy. Proceeds will go to support the Borish Center for Ophthalmic Research. Contact Hillary
Person at 812-855-0351 or hlheflin@indiana.edu for more information.
Allergan Introduces Optive
Allergan has announced the launch of Optive lubricant eye drops, a new artificial tear product that the company says works both on the
ocular surface and at the cellular level to relieve dry eye symptoms. The company says in cases of dry eye, the tear is hypertonic, so it does not sufficiently hydrate
or protect the surface of the eye. Optive provides a lubricating and hydrating shield on the surface of the eye, then penetrates below the surface to provide
osmoprotection to the corneal epithelial cells, according to the manufacturer.
Optive is available in multi-use bottles and preserved with purite, a preservative
that the company says dissolves into natural tear component without resulting in cellular damage to the ocular surface.
Soft CL Inventor Honored
This year’s National Inventors Hall of Fame inductees will include among them Otto Wichterle, inventor of the soft contact lens. Each
year, the National Inventors Hall of Fame honors individuals whose work have changed society and improved the way we live. Otto Wichterle’s soft contact lens proved
to be less expensive and more comfortable than previous models. The group says a significant part of his invention was the process for making the lenses. Arthur Nobile
will also be inducted for his discovery of the steroids prednisone and prednisolone, a significant advance in medicine. They will be inducted at the annual induction
ceremonies in Akron, Ohio on May 4th and 5th.
Wet Lens, Patient Satisfaction
Among those ages 35-49, 65% of patients who consider dropping out of contact lens wear cite dryness sensation as a key
reason. ACUVUE® OASYS™ Brand Contact Lenses with HYDRACLEAR™ Plus are made from senofilcon A, a next generation silicone hydrogel material. The proprietary
formulation includes a remarkable moisture-rich wetting agent and no surface coating. The senofilcon A material balances properties to meet the demands of contact lens
wearers in environments that can make eyes feel tired and dry. This breakthrough material creates a lens so moist and smooth that an eyelid glides effortlessly over
it. ACUVUE® OASYS™ Brand Contact Lenses can help keep your patients in contact lenses by increasing their comfort and also giving them crisp vision and
healthy lens wear.

Press Conference Educates Legislators on Children’s Vision
A congressional briefing and press conference on Capitol Hill this month was held in an effort to raise awareness for H.R.
507, the “Vision Care for Kids Act of 2007.” Pediatric ophthalmologist Jean Ramsey, M.D. and pediatric optometrist Andrea Thau, O.D., shared real-life examples of
children who could have benefited from preventative vision care with more than 60 participants.
H.R. 507 is sponsored by U.S. Reps. Gene Green (D.-Texas), Eliot
Engel (D.-N.Y.), Vito Fossella (R.-N.Y.), Bill Pascrell (D.-N.J.), Ileana Ros-Lehtinen (R.-Fla.) and John Sullivan (R.-Okla.). The bill is supported by the alliance
of the Vision Council of America (VCA), American Academy of Ophthalmology (AAO), the American Association for Pediatric Ophthalmology and Strabismus (AAPOS), the
American Optometric Association (AOA) and Prevent Blindness America (PBA). For more information or to support the legislation,

Abstract:
Microbial Contamination in Young CL Wearers
Researchers at the Hong Kong Polytechnic University’s School of Optometry in China recently conducted a study to examine the rates of
microbial contamination and identify contaminants associated with contact lenses and lens care accessories used by a group of young contact lens wearers. They
performed bacterial cultures on contact lenses, cases and care solutions collected from participants.
Of the samples tested, they found 9% of lens extracts, 34% of
case extracts and 11% of solution samples were contaminated with ocular pathogenic microorganisms. The most common microorganisms isolated were
Serratia
spp., Staphylococcus aureus and coagulase-negative staphylococci. Lens cases were found to be the most frequently contaminated item and also yielded the widest
range of bacterial isolates. Contact lenses used by occasional wearers were associated with a higher contamination rate. The investigators note that using either
saline or multipurpose solution to rinse the lenses before insertion appears to be an effective method of reducing incidence of contamination.
They conclude the
finding demonstrate that contact lenses and lens care accessories are not well maintained by contact lens wearers and suggest regular reviews and enforcement of lens
care procedures is essential.

Editor's Commentary:
GKC Buzz Continues
We continue to get lots of positive feedback on the first Global Keratoconus Congress (GKC). Like many meetings, the GKC depends on
industry support. We would like to extend our thanks to all of our sponsors and exhibitors that helped make the inaugural congress a success. You can view pictures
of attendees, exhibits, posters and speakers
at http://www.healthcareconferencegroup.com/conferences.asp?conf=78&page=8. If you
attended, please send us any contact lens tips you learned during the meeting and share them with your colleagues.
Fitting Tip:
Keratoconus Tip
Keep the back surface of the GP lens worn for keratoconus very clean, with daily cleaning using a surfactant and/or particulate
cleaner (for non-surface treated lenses) and enzyme cleaning. Or use Progent every six months to prevent protein buildup from causing corneal erosion.
The
Editor
This month at http://www.siliconehydrogels.org, review the results of a study
on non-compliance in contact lens wearers, learn about piggyback fittings of silicone hydrogels for post-surgical patients, consider the benefits and challenges
of spherical lens, soft lenses and silicone hydrogel lenses for toric lens wearers, and evaluate the fitting practices of Canadian optometrists from
2000-2006.
