We all know that some of our patients require a custom approach to cleaning and caring for their contact lenses' perhaps about 10% of our patients are "heavy" depositors. We do have advanced systems that we can use in that regard. Alternatively, it is important to not forget about two other critical elements that can aid in optimizing lens wear for these patients' material chemistry and replacement schedule. It is well known that some elements of contact lens polymers are more attractive to deposits than others. Likewise, we generally know that reducing the replacement schedule can aid in improving contact lens hygiene.
Alden Optical announced that it has initiated an email series of 12 case studies on contemporary scleral lens fitting. â€œScleral Fitting from A to Zen,â€ edited by Susan J. Gromacki, OD, MS, FAAO, will include cases prepared by leading North American scleral lens fitters, demonstrate fitting techniques across a wide range of ocular conditions and feature Alden Opticalâ€™s Zenlens scleral design. Zenlens, with two diameters (16mm and 17mm) and two designs (prolate and oblate), was designed specifically to fit a wide range of ocular conditions.
With the email series, the company hopes to increase interest in scleral fitting by showcasing the breadth and ease with which practitioners can utilize Zenlens. The series will be deployed across PentaVisionâ€™s email database and will be archived on both the Contact Lens Spectrum and Alden Optical websites.
The EyeCatcher is a new product designed to help contact lens wearers not lose their lenses. It is ergonomically designed to be placed over an open stopper located in any style bathroom sink during lens cleaning, application or removal. The EyeCatcher creates a barrier in the sink drain, while allowing easy flow of contact lens solution when rinsing, thus providing a suitable technique to handle contact lenses.
Lucretia Williams, the creator of the EyeCatcher, was diagnosed with keratoconus 15 years ago and is a long-term contact lens wearer, currently wearing a piggyback combination of soft and GP lenses. Williams said the idea for the product came about after losing multiple lenses.
The EyeCatcher is currently available in Seaside Blue with BrickHouse Red debuting in summer 2015. For more information visit http://www.savemycontact.com.

Alcon, a division of Novartis, received approval from the U.S. Food and Drug Administration (FDA) of Pazeo (olopatadine hydrochloride ophthalmic solution) 0.7%, for the treatment of ocular itching associated with allergic conjunctivitis. Pazeo solution is dosed one drop daily, and was approved with efficacy data at 24 hours, post dose.
The safety profile of Pazeo solution is comparable to that of olopatadine 0.2%. Pazeo solution is expected to be available by prescription in the United States in March, followed by Latin American and Asian markets through 2017.
The Association of Schools and Colleges of Optometry (ASCO) announced the awarding of the first Partnership Endowment Grants. In its inaugural year, the Partnership Endowment will award $148,000 to 17 schools and colleges of optometry. Grants will be used to support programs or projects that include faculty development, creating a diverse, highly-qualified applicant pool, clinical training, or any other purpose that advances optometric education.
The Partnership Endowment was established in 1996 as the Partnership Foundation for Optometric Education. The American Optometric Association and ASCO created the Foundation as a means to provide financial support for the advancement of optometric education. Since its establishment, every national optometric organization has participated in supporting the Partnership Foundation.

Contact lens comfort is a major topic and we bring it up a lot. We are looking for the times that it is encountered by our patients, and usually it is the end of the day. What if, we simulated the most challenging environments possible for our patients? For those of us who live in more tropical environments than Colorado or Phoenix, we can send our patients to one of these places, but in reality that is an expensive feat. Here is a new question to ask your patient: What do your contact lenses feel like when you are flying? As I was getting prepared for a flight this morning, I put my own contact lenses in and, being a mild dry eye patient, wondered how my eyes were going to feel. Since there are 3 billion flyers in the world in any given year, there is a good chance that many of your patients fly at some point. When it comes to a material for your patients, we want them to be comfortable when they are in the most challenging environments. If your patient reports that his eyes begin to dry out on a flight, this may be an early warning sign that when faced with a challenge, your patientâ€™s lenses may fail.

CDC at GSLS
I attended the Global Specialty Contact Lens Symposium (GSLS) in Las Vegas again this year, and as always, it did not disappoint. All total, this yearâ€™s meeting featured a record attendance with participants from more than 30 different countries.
GSLS had the special privilege of welcoming Jennifer Cope, MD, MPH, from the United States Centers for Disease Control and Prevention (CDC), as a presenter at the symposium. She is a medical epidemiologist with the Waterborne Disease Prevention Branch at CDC, which is the lead coordination and response unit in the National Center for Emerging and Zoonotic Infectious Diseases. She presented an overview of CDC's Acanthamoeba keratitis investigations.
Following the outbreak of contact lens-related Acanthamoeba keratitis (AK) in 2007, CDC conducted a study which determined that even following a solution recall, the number of cases diagnosed annually did not return to levels observed before the outbreak. Dr. Cope noted that, â€œThere is no evidence that the outbreak was associated with a nationwide change in water treatment.â€ As a result, in 2011 CDC conducted the largest case-control study to date of AK. Although the results have not yet been published, they certainly can aid our understanding of what may be contributing to the persistence of cases.
The following risk factors were significantly associated with infection:
Miraflow, Soft Contact Lens Cleaner: Activity Against Acanthamoeba Spp.
Miraflow is a cleaner for soft contact lens which contains 20% isopropyl alcohol. The purpose of this study was to determine the activity against Acanthamoeba trophozoites and cysts for Miraflow. In addition, to determine the activity of combined Miraflow and multipurpose solutions (MPS) against Acanthamoeba cysts.
Two simulated-use studies were conducted. The significance in the log reduction in the number of trophozoites and cysts of A. castellanii strains ATCC 50514 and ATCC 50370 or A. polyphaga ATCC 30461 after exposure to Miraflow alone was determined by the Spearman-Karber method. To examine the activity against Acanthamoeba of combined Miraflow and an MPS, the log reduction in the number of cysts after a one-minute exposure to Miraflow followed by a four-hour exposure to MPS (ReNu fresh) was also determined.
Short-time exposure of 30 seconds to Miraflow demonstrated activity against the Acanthamoeba trophozoites. However, a one-minute treatment was only relatively effective (1.1 log reduction) against the cysts of A. castellanii ATCC 50514, but no statistically significant reduction was observed for the cysts of the other two strains. The combined use with Miraflow and MPS demonstrated activity against the cysts, and a 3.0, 1.0, or 1.5 log reduction in the numbers was obtained for A. castellanii ATCC 50514, A. castellanii ATCC 50370, and A. polyphaga ATCC 30461, respectively.
The authors concluded that exposure to combined Miraflow and MPS resulted in reductions in the number of Acanthamoeba cysts.
