I recently became aware of some very disturbing potential legislation in the state of Arizona that would remove brand specification on contact lens prescriptions. This would essentially allow patients to self-prescribe what they considered to be the best contact lens for themselves. This idea is obviously alarming as we know that specific brands have different material characteristics and design parameters that affect the fit of the lens, ultimately impacting the safety and efficacy of the contact lens on-eye. For more information on these issues, please visit the following link with a detailed story written by our good colleague Dr. Art Epstein: http://www.reviewofoptometry.com/e-newsletters/opnl/c/58329/.

Introducing SpectraVue Translating Progressive GP Multifocal
Fused Kontacts, Division of Diversified Ophthalmics Inc., introduces their newest GP multifocal contact lens, SpectraVue translating progressive by Tangent Streak. According to the company, this breakthrough design provides the same visual capabilities as a PAL spectacle lens but without the corridor limitations.
Manufactured using unique proprietary CNC lathe software, SpectraVue offers patients a spherical power upper segment, wide crescent progressive intermediate segment, and spherical power near correction. The crescent segment design and a radical new edge configuration have eliminated the need for truncation. The result is a GP lens that can be comfortably worn for 16 hours a day.
In limited release since February, practitioners have found they can fit this tolerant design using an easy-to-follow fitting guide. Only standard eye measurements, such as refractions, HVID, lower lid position, and vertical fissure, are needed. Loaner or earnable fitting sets of positionally identifiable diagnostic lenses are also available. Experienced fitting consultants are available to assist at any point in the process.
SpectraVue is available in all FDA-approved GP materials and colors, five standard diameters, standard seg heights, intermediate powers, and the full range of distance and near powers. All parameters are also fully customizable. As such, SpectraVue is a design intended for aspheric multifocal failures (soft or GP) and all patients who require sharp distance, near, and intermediate visual acuity.

CareCredit Provides Grant to InfantSEE Program
CareCredit’s Caring Communities Program is making a difference in the vision health of children with a $25,000 grant to Optometry Cares - The AOA Foundation’s InfantSEE program. This marks the fourth consecutive year CareCredit, a leading health wellness and beauty credit card, has contributed to InfantSEE.
More than 7,300 InfantSEE optometrists examine an estimated 10,000 infants annually for normal eye development and to intervene early if necessary. To date, more than 122,000 babies have been seen and 10 percent have been identified for greater concerns and follow-up.
CareCredit’s grant will be used to expand awareness of the InfantSEE program among new parents through print advertising, brochures, signage and displays, and online efforts.
Sceleral Lens with Excessive Edge Clearance Boris Severinsky, FAAO, FBCLA, FSLS, Aventura, FL

As I write this, I am over the Atlantic on my way to Europe for a meeting. I am enjoying the recycled air and dryness that the airplane cabin is providing me, forcing me to experience life through my patient’s eyes.
Air travel is a mainstay for many of our patients. Whether they travel once a year or weekly, the challenge that air travel places on the ocular surface is substantial. Many patients elect to go without their contact lenses when traveling because of the increased dryness, but for others, this option is either not realistic or too cumbersome for them. As such, millions of eyeballs go through the challenge of airline ocular surface stress on a daily basis.
What can be done for our patients? Although we encounter many challenges for our patients, when it comes to those that we know travel on a regular basis, we want to bring an added level of fitting and education.
First, ensure that your patients are wearing a clean lens. A clean lens will provide a more smooth surface whereas a dirty lens allows for the ocular surface to become disrupted. We usually go about this in our office through the use of a single use lens, however if the patient is in a specialty or less frequent replacement lens, this is best done with a rub and rinse solution. We usually favor peroxide in our office.
Next, it is ever critical for patients to have regular and complete blinks so as to make sure that the proper tears are created and delivered across the lens. If your patient travels regularly, educate them on the benefits of bringing artificial tear drops with them to be used over the contact lenses as well as ensuring that the patient remembers to forcefully blink at regular intervals before and during their flight.
Patients are going to travel and they are going to be in ocular surface stress. Educate them on clean lenses, wet lenses, and proper blinking. This will help make their friendly skies experience as lubricated and clear as possible.

Love What You Do
In my last column, I wrote about patient noncompliance and one way to improve it: be the role model that your patients do not want to disappoint. How is this achieved? Well, volumes of books have been written on the topic of leadership, and it would take more than this column to summarize their findings. Although some experts contend that leaders are born, most agree that leadership traits can be learned—and developed—over time.
There is one proven way to immediately instill patient confidence in your abilities and in your message: let them see that you enjoy your work. As Steve Jobs said, “The only way to do great work is to love what you do.”
Can those stagnating professionally find meaning and success? Absolutely; there are many things we can do. First, reflect back on why you selected your career in the first place. Connect with an old classmate and reminisce about what made learning fun; attend CE in an exotic location, or from someone passionate about optometry (e.g. yours truly); participate in a clinical study; write a blog, article, or scientific poster about an interesting case you solved; purchase a new piece of equipment for your practice; participate in a VOSH trip; join one of our collegial organizations, such as NOA, AOA, or AAO; or take the time to meet with your sales reps to learn what exciting new technologies you can offer your patients—and then offer them.
In short, a piece in Forbes Magazine stated that true job satisfaction is gained not just from day-to-day activities, but even more so by loving the impact your job has on someone else. In our profession, that means if we focus on how much we have helped the recipients of our work—our patients—then we can’t help but love what we do.
Effect of Ambient Temperature on the Human Tear Film
During everyday life, the tear film is exposed to a wide range of ambient temperatures. This study aims to investigate the effect of ambient temperature on tear film physiology.
A controlled environment chamber was used to create different ambient temperatures (5, 10, 15, 20, and 25°C) at a constant relative humidity of 40%. Subjects attended for two separate visits and were exposed to 25, 20, and 15°C at one visit and to 10 and 5°C at the other visit. The subjects were exposed to each room temperature for 10 minutes before investigating tear film parameters. The order of the visits was random. Tear physiology parameters assessed were tear evaporation rate, noninvasive tear break-up time (NITBUT), lipid layer thickness (LLT), and ocular surface temperature (OST). Each parameter was assessed under each condition.
A threefold increase in tear evaporation rate was observed as ambient temperature increased to 25°C (P=0.00). The mean evaporation rate increased from 0.056 μL/minute at 5°C to 0.17 μL/minute at 25°C. The mean NITBUT increased from 7.31 sec at 5°C to 12.35 sec at 25°C (P=0.01). A significant change in LLT was also observed (P=0.00), LLT median ranged between 20 and 40 nm at 5 and 10°C and increased to 40 and 90 nm at 15, 20, and 25°C. Mean reduction of 4°C OST was observed as ambient temperature decreased from 25 to 5°C.
The researchers concluded that ambient temperature has a considerable effect on human tear film characteristics. Tear evaporation rate, tear LLT, tear stability, and OST were considerably affected by ambient temperature. Chronic exposure to low ambient temperature would likely result in symptoms of dry eye and ultimately ocular surface disorders.
