There is no doubt that social media has exploded over the last decade with up to or more than two-thirds of American adults reporting its use (http://www.pewinternet.org/2015/10/08/social-networking-usage-2005-2015/). We are finding many unique ways that social media impacts the medical profession in general, as well as us as eyecare and contact lens practitioners. In addition to our traditional website and this email you are presently reading, we encourage you to also follow us on Facebook (www.facebook.com/contactlensspectrum) and twitter (Twitter @CLS_magazine) to pick up more contact lens tips and trends that will impact your practice.

New 90-Pack Available for clariti 1 Day Multifocal
CooperVision, Inc. announced the addition of a 90-pack configuration for clariti 1 day multifocal contact lenses, which provide presbyopic patients with the benefits of silicone hydrogel material and the advantages of a 1-day modality.
clariti 1 day contact lenses were added to CooperVision’s product portfolio through the company’s 2014 acquisition of Sauflon Pharmaceuticals Ltd. In the following months, CooperVision expanded clariti 1 day’s availability throughout the U.S. Until now, clariti 1 day multifocal lenses were available only in 30-pack cartons.
CooperVision offers a robust multifocal contact lens portfolio to treat presbyopic patients, including those with astigmatism. clariti 1 day lenses feature high water content to support excellent all-day comfort. WetLoc technology ensures the entire lens surface is continuously moist and mimics the moisture dispersion of naturally healthy eyes, according to the company. clariti 1 day lenses have a high oxygen transmissibility—which allows 100 percent corneal oxygen consumption and also helps maintain ocular health.
clariti 1 day multifocal lenses feature a base curve of 8.6 mm, a diameter of 14.1 mm, and a Dk/t (@-3.00D) of 86, with a power range of +5.00 to -6.00D (0.25 steps) with ADD powers of Low (up to +2.25D) and High (+2.50 to +3.00D).

Held every two years, the International Association of Contact Lens Educators Fellowship Exam took place in November 2015. Candidates with a successful outcome who have been IACLE members for 12 months or more can now apply to become Fellows of IACLE and use the affix FIACLE in recognition of their contact lens knowledge.
A total of 131 members from 29 countries in all three of IACLE’s global regions sat the latest exam and 39% were successful. More than half of candidates (56%) were from IACLE’s Global Priority Countries. The Asia Pacific region fielded the most candidates, with 89 in total. The next largest numbers were contributed by the Americas (29) and Europe/Africa-Middle East (13), China (24), India (23), and Korea (18). The 2015 Fellowship Exam also saw countries such as Oman and Malawi represented.
A majority of candidates (107) were Educator Members, working full time or part time at a recognized teaching institution, and 24 were Associate Members of whom 13 worked in industry. All IACLE’s Platinum and Silver Sponsors fielded candidates. Most of those sitting the exam were optometrists (62%) although 8% were ophthalmologists.
The 2015 Fellowship Exam was the 10th administration. The next exam will be held in November 2017. Anyone interested should start to think about engaging with the IACLE’s Distance Learning Program now to aid their preparation for the next Fellowship Exam.

What Is Protecting Us?
The body has an amazing immune response. Our ability to fight infection and foreign invaders is beyond what science has fully explained. One of those challenges is seen when we wear contact lenses. Many of our patients do get an infection at some point. This is when the barrier function is not able to ward off the invaders and either a microbial or inflammatory reaction occurs. In reality the complexity of the tear film and the corneal surface is disrupted when we put a contact lens on the eye. If this contact lens is not perfectly clean and contaminate free, our body has to withstand the harsh reality of fighting off this foreign invader’s (the contact lens) nasty side effects. We know that the eye creates a T-cell mediated inflammatory reaction when it is constantly bombarded by environmental challenges like arid climates or harsh chemicals. When placed in the presence of a contact lens, the ocular surface also goes through some intense bombardments that need to be carefully managed by us. After all, we know that as many as 50% of contact lens wearers experience some form of discomfort with their lenses. Switching the lens alone rarely solves the problem; otherwise, most people would not drop out, due to dryness and discomfort, before the age of 40.
Consider these two steps when managing your patients with discomfort: 1. Ensure the patient is in the best material and replacement schedule lens. 2. Treat the ocular surface as if it is a dry eye patient. Don’t forget to do these in unison. This will help to slow future damage and keep our patients wearing lenses for a very long time.

Extreme Contact Lens Abuse
When I first graduated from optometry school, I took a number of fill-in jobs in the greater Columbus, OH, area to build my skills and make some extra income while continuing my graduate studies. While I found that I enjoyed the work, these opportunities often put me in many new and sometimes uncomfortable situations.
One situation that I still remember vividly is facing my first extreme contact lens abuser. My patient, who was in her mid-fifties, reported for her annual contact lens exam. After taking history and performing a few tests, I quickly saw on my slit-lamp examination the most prolific corneal vascularization that I have ever seen: there was only about a 2 mm round clear window on each cornea. Upon further questioning, my patient admitted that she had not taken off her two-week hydrogel contact lenses for over six months. These findings prompted me to educate and advise my patient that she should discontinue contact lens use. In short, this advice infuriated my patient. She insulted me, and she went on to make a scene in the patient waiting area before finally leaving the office.
Looking back several years later, I would still make the same decision today. With that said, there is always going to be some grey area in these types of situations, and the decision to discontinue contact lens use is going to be a difficult one. In the end, we need to keep in mind that cosmetic contact lenses are a privilege for the patient, and that we are legally responsible for our patients’ health. I suggest that you bear these two points in mind to help you make difficult decisions.
Changes in Peripheral Refraction, Higher-Order Aberrations, and Accommodative Lag with a Radial Refractive Gradient Contact Lens in Young Myopes
The purpose of this study was to evaluate changes in the peripheral refraction (PR), visual quality, and accommodative lag with a novel soft radial refractive gradient (SRRG) experimental contact lens that produces peripheral myopic defocus.
Fifty-nine myopic right eyes were fitted with the lens. The PR was measured up to 30° in the nasal and temporal horizontal visual fields and compared with values obtained without the lens. The accommodative lag was measured monocularly using the distance-induced condition method at 40 cm, and the higher-order aberrations (HOAs) of the entire eye were obtained for 3- and 5-mm pupils by aberrometry. Visual performance was assessed through contrast sensitivity function (CSF).
With the lens, the relative PR became significantly less hyperopic from 30° to 15° temporally and 30° nasally in the M and J0 refractive components (P<0.05). Cylinder foci showed significant myopization from 30° to 15° temporally and 30° to 25° nasally (P<0.05). The HOAs increased significantly, the CSF decreased slightly but reached statistical significance for 6 and 12 cycles per degree (P<0.05), and the accommodative lag decreased significantly with the SRRG lens (P=0.0001). There was a moderate correlation between HOAs and CSF at medium and high spatial frequencies.
The researchers concluded that the SRRG lens induced a significant change in PR, particularly in the temporal retina. Tangential and sagittal foci changed significantly in the peripheral nasal and temporal retina. The decreased accommodative lag and increased HOAs particularly in coma-like aberration may positively affect myopia control. A longitudinal study is needed to confirm this potential.
