Technology is continually expanding and moving boundaries for us in all aspects of our lives. It is truly amazing and exciting to see the conveniences that new technologies afford us each day. On the other hand, technology creates occasional headaches--computers and other digital devices and their use, particularly over long periods of time, are clinically associated with a variety of ophthalmic-related conditions including headaches, eyestrain and fatigue, discomfort and dry eye. It is thought by some that these problems are further exacerbated by the use of contact lenses, but this is not entirely clear. There is no doubt that the optical quality and vision-related performance of a contact lens depends on a stable pre-lens tear film. Often, these problems are a challenge to manage given that employment or social needs mandate our patients use of technology. We as eyecare practitioners need contact lens materials and designs that will help us overcome these challenges, allowing our patients to wear contact lenses in a variety of challenging environments.
Alcon is now engaged in a major national television, online and print media campaign in support of Air OptixColors prescription contact lenses, the first color contact lens in the U.S. to encapsulate Alconâ€™s 3-in-1 Color Technology in a silicone hydrogel lens.
This national media campaign is aimed at reaching the fashion-forward and beauty-savvy female consumer through TV, online and print media. Thirty-second and 15-second television spots are now airing on several major network and cable channels, including NBC, CBS, TNT, TBS, Lifetime, Oxygen and more. A full-page print advertisement also targets females through placements in fashion and beauty magazines, including Glamour, Seventeen, Nylon, Teen Vogue and OK!
The fashion-focused ads feature brown-eyed model Sofia enhancing her look with Air Optix Colors contact lenses in Sterling Gray. Consumers get a close-up look at her eyes before and after inserting the contact lens, and are encouraged to virtually try on their perfect color at www.airoptixcolors.com or by visiting an eye care professional. In addition to product promotion, the campaign is designed to help ensure that patients understand that Air Optix Colors contact lenses are prescription medical devices that require a visit to their eye doctor.
Air Optix Colors contact lenses were introduced in the United States earlier this year. Available in nine colors ranging from subtle to vibrant, the contact lenses are the first monthly replacement, daily wear color lenses available in the U.S. on a silicone hydrogel platform, allowing up to six times more oxygen through the contact lens compared to the leading, older technology color contact lens.1 The natural-looking color is contained within the innovative lens material, so that the only thing touching the wearerâ€™s eyes is the ultra-smooth permanent plasma surface of Air Optix brand contact lenses.
Eyecare professionals may prescribe the lenses to correct vision or in plano. Importantly, there is no refit required for current Air Optix Aqua contact lens wearers.2

Optometry Cares - The AOA Foundation calls upon fourth-year optometry students to apply for the Dr. Pat & Patrick Cummings Scholarship, which is worth $5,000.
The scholarship is in memory of AOA Past President, Pat Cummings, OD, who had a love for volunteering in his profession and making a positive impact in the community. Among many acts of philanthropy, Dr. Cummings was one of the first supporters of the InfantSEE program, which helps provide no-cost eye examinations for children during their first year of life. The Cummings family faced terrible loss when Dr. Cummings died July 11, 2009 in a private plane crash. In a separate tragedy, his son, Patrick, passed away in a car accident at age 18.
In tribute to father and son, the Dr. Pat & Patrick Cummings Memorial Fund was established through Optometry Cares. This opportunity was generously funded by numerous individual donors, as well as a large contribution from Johnson & Johnson Vision Care.
Among other qualifications, to be eligible for the Dr. Pat & Patrick Cummings Scholarship, a student must obtain one letter of recommendation from a teacher, dean or academic advisor, and submit an essay that answers the following questions:
Dr. Pat Cummings was passionate about improving the overall health of the public. How do you exemplify this passion and what are your goals in the area of public health?
Do you plan to take a leadership role in optometry? Please tell us about leadership roles you have had in optometry school and your future leadership goals.
Students must check with the student affairs office to determine the institutionâ€™s on-campus deadline. Each school and college will choose one candidate from all applications received by their on-campus deadline and forward the individualâ€™s name and essay to Optometry Cares by November 11, 2014. The winner will be announced in January 2015.

This is a 19 year-old female (-8.00-2.50 x 165 vertexed @ 12 mm), non-ectatic, irregular cornea case. This case was taken on in 2012 (upper right) and we switched her corneal lenses to a custom designed GP intralimbal reversed geometry lens in 2013 (lower left). The goal was accomplished: good visual acuity, excellent comfort (better centration and apical clearance) and a healthy lens-cornea relationship. In 2014 (lower right), a scleral lens was custom-designed in response to her request to wear stable lenses in sport activities. In my opnion, scleral lenses are a safer solution in outdoor circumstances.

Infectious Keratitis Associated with Corneal Reshaping â€“ Itâ€™s Important to Look at the Details
A review of cases of infectious keratitis associated with the use of Orthokeratology (corneal reshaping) contact lenses treated at a tertiary care clinic in Hong Kong was recently published.1 Data analyzed included clinical features, microbiological evaluation, and treatment outcomes. 23 patients were included (mean age, 15.0 Â± 4.2 years; range: 9 to 23 years). All patients were using overnight corneal reshaping / Orthokeratology contact lenses for an average of 2.7 Â± 2.8 years (range: 3 months to 10 years) before the onset of infection. Fifteen eyes (65.2%) had a positive microbiological culture obtained from corneal scrapings. The most commonly isolated organism was Pseudomonas aeruginosa (n=6) followed by coagulase-negative Staphylococcus (n=5) and Acanthamoeba (n=3). Five cases of Pseudomonas aeruginosa and 5 cases of Acanthamoeba were identified from contact lenses or contact lens solution. All patients responded to medical treatment, and no surgical intervention was needed. The best-corrected logMAR visual acuity improved significantly from 0.62 Â± 0.51 (20/83 Snellen) to 0.15 Â± 0.20 (20/28 Snellen) (Wilcoxon signed rank test, p < 0.001). The authors stated that corneal reshaping / Orthokeratology-associated infectious keratitis is a serious problem especially in regions with high prevalence of myopia (such as Asia). Early clinical and microbiological diagnosis and intensive treatment can improve final visual outcomes.
Prior work by Watt & Swarbrick2 did a comprehensive literature review of microbial keratitis cases reported with Orthokeratology and found that most cases occurred in East Asia (specifically China and Taiwan) and that most occurred during a short time period associated with lack of regulation of Ortho-K fitting in those regions. Risk factors determined in this study were inappropriate lens care, patients not following practitionerâ€™s instructions, and continuation of lens wear despite discomfort. A post market study of Orthokeratology conducted by the FDA and the Ohio State University showed an incidence of microbial keratitis of 7.7 per 10 000 person-years of wear, making Orthokeratology wearers only slightly more susceptible to infection than daily wear soft contact lens wearers at 4.1 per 10 000.3 This rate is lower than that found with continuous wear of soft contact lenses which range from about 18 to 20 per 10 000.4
What we can say is that microbial keratitis is a risk factor for all forms of contact lens wear. Overall corneal reshaping / Orthokeratology has a similar risk for MK as with other modalities of contact lens wear. It is critically important to realize that many of our corneal reshaping patients are children and that special care is needed to avoid any complications that could potentially lead to any degree of vision loss. Strict attention to lens care, lens hygiene and use of approved materials and designs will continue to allow practitioners to provide an effective and safe modality of vision correction for our patients undergoing corneal reshaping / Orthokeratology treatment.

OCULAR SURFACE UPDATE Katherine M. Mastrota, MS, OD, FAAO
What is “Ocular Surface Wellness”?
How do we define, assess and maintain ocular surface wellness (OSW)?
In early 2014, Alcon convened an advisory board meeting of experts in ocular surface care to discuss these questions.
Moderated by Dr. Kelly Nichols, the Alcon-sponsored advisory board aimed first to outline OSW. Via consensus, OSW was defined as follows:
â€œOcular surface wellness, a prerequisite for ocular comfort, clear vision, and healthy looking eyes, is promoted through engaging eye care practitioners, patients, and the public in education and awareness activities, encouraging early detection and management, and efforts to preserve lifelong ocular surface health.â€
Numerous barriers remain as clinicians forge ahead in the OSW concept: the need for agreed-upon protocols for screening, diagnosis, and evidence-based management of ocular surface conditions remain as major concerns.

Citation Parameters of Contact Lens-Related Articles Published in the Ophthalmic Literature
This study aimed at exploring the citation parameters of contact lenses articles published in the Ophthalmology thematic category of the Journal Citation Reports (JCR).
The Thompson Reuters Web of Science database was accessed to record bibliometric information and citation parameters of all journals listed under the Ophthalmology area of the 2011 JCR edition, including the journals with main publication interests in the contact lens field. In addition, the same database was used to unveil all contact lens-related articles published in 2011 in the same thematic area, whereupon differences in citation parameters between those articles published in contact lens and non-contact lens-related journals were explored.
Significant differences in some bibliometric indicators such as half-life and overall citation count were found between contact lens-related journals (shorter half-life and fewer citations) and the median values for the Ophthalmology thematic area of the JCR. Visual examination of all Ophthalmology journals uncovered a total of 156 contact lens-related articles, published in 28 different journals, with 27 articles each for Contact Lens & Anterior Eye, Eye & Contact Lens, and Optometry and Vision Science. Significant differences in citation parameters were encountered between those articles published in contact lens and non-contact lens source journals.
The authors concluded that these findings, which disclosed contact lenses to be a fertile area of research, may be of interest to researchers and institutions. Differences in bibliometric indicators are of relevance to avoid unwanted bias when conducting between- and within-discipline comparisons of articles, journals, and researchers.
