There is no doubt that in the Northern Hemisphere spring is indeed in the air (note this week’s abstract on the topic)! Spring is a time for rebirth, rejuvenation, renewal and regrowth. It’s a season of change and a great time to dust things off, including the contact lens aspects of our practices. Whether it is trying a new contact lens modality in your patients or providing some needed contact lens education to your staff, I encourage you to do something new. Do so with vigor and passion so that it inspires your staff to believe in your vision.

Art Optical Introduces Ampleye
Art Optical announces the availability of their new 16.5mm scleral lens, Ampleye. Designed to fully vault the cornea and limbus and land gently on the sclera with 360° of alignment, Ampleye ensures no corneal involvement, so irregular cornea fitting is simplified and patient comfort is maximized, according to the company. With a goal of incorporating the latest understanding on scleral shape into the lens, Ampleye designers have included 150 microns of scleral toricity in both diagnostic and Rx lenses. The toric haptic more precisely matches the true shape of the human sclera, ensuring a simplified diagnostic assessment process and increased predictability of the trial lens performance, reducing chair time and improving first-fit success by eliminating guesswork on Rx orders.
In addition to the toric haptic, other unique Ampleye design features include 4-zone construction with Spline Science Technology, providing independent zone adjustments for finite control of the lens fit, and an optimally engineered landing zone for wide and even distribution of pressure, minimizing blanching potential and edge modification requirements.
Plus the company states that, aided by inherent toricity, the natural tear layer and the full circumference lens closure create a HydroLock chamber, ensuring soothing moisture retention for lasting hydration and comfort, potentially relieving symptoms of dry eye and ocular surface disease.
The 9-lens Ampleye diagnostic set is efficient, affordable and designed to fit a wide range of eyes. The simplified diagnostic selection process involves fitting by patient condition, not K-readings, with the depth of the eye determining the initial depth of the trial lens. Ampleye diagnostic lenses are laser-marked with sag values and axis rotation indicators for easy on-eye assessment. Art Optical will feature Ampleye lenses in Optimum Extra material by Contamac.

The IACLE Travel Award is a travel bursary for an IACLE Educator Member starting out on his/her career who would not otherwise be able to attend a major international conference. The annual Award is funded by IACLE. This year’s recipient is Eman Alzghuol, lecturer in contact lenses at Jordan University of Science and Technology, Irbid, Jordan.
Decentered Hybrid Lens Stephanie L. Woo, OD, FAAO, Lake Havasu, AZ
This patient has a decentered hybrid lens. It centers inferiorly and does not move with blink. However the pateint’s vision was 20/25 through this lens. After consultation, a new lens was ordered.
We thank Dr. Woo for this image and welcome photo submissions from our other readers! It is easy to submit a photo for consideration for publishing in Contact Lenses Today. Simply visit http://www.cltoday.com/upload/upload.aspx to upload your image. Please include a detailed explanation of the photo and your full name, degree or title, and city/state/country.

Capsaicin and Contact Lenses
I enjoy cooking spicy foods; however, their ingredients do not always mix well with contact lenses. Capsaicin (chili powder) is commonly added to foods that originate from warmer climates; this tradition arose possibly because capsaicin has antibacterial properties and spicy foods carry a natural ability to resist spoilage.1 Unfortunately for contact lens wearers, capsaicin is a hydrophobic molecule that has the potential to bind to contact lenses and cause extreme discomfort.1
This issue was exemplified by one of my recent cases. I was fitting a neophyte into soft contact lenses. At the initial fitting, my patient reported good and comfortable vision with her new disposable contacts, yet when she reported for her follow-up visit, she indicated that her right contact lens was causing her extreme discomfort, and she was unable to wear it. Upon further investigation I determined that my patient first noticed the discomfort after cooking with peppers. She also noted that she had washed her hands and was careful, yet she still likely contaminated her contact lens. My patient did not have any issues after she replaced the contact lens.
This case displays the need for patients to be careful with daily tasks, because even simple activities such as cooking could potentially result in extreme eye discomfort and damaged contact lenses. It is much easier to contaminate contact lenses than one might think. As a practitioner, you may want to educate your patients about these hazards, and you could even recommend that they wear gloves while working with potential irritants.

Are contact lenses putting fuel to the fire of ocular inflammation? We conducted a study at our practice recently and were shocked at the level of inflammation in the general patient population. About 63% of patients in our practice tested positive for MMP-9 ≥ 40 ng/mL, which was higher than in our dry eye population! Then imagine putting a foreign object, like a contact lens, on these inflamed eyes and the possible corneal health ramifications over the patient’s lifetime. Not good.
So how do we minimize exacerbating ocular inflammation with contact lenses? If I haven’t started sounding like a broken record yet, here it is again: daily disposables are the best contact lenses for patients because they are the healthiest lenses. They’re the best option we have to minimize contact lens complications secondary to inflammation, especially ones that occur due to lens overwear, sleeping in lenses, etc. A fresh contact lens on the eye every day prevents protein build-up, reduces the risk of microbial keratitis and subepithelial infiltrates, and makes for a happier, whiter eye.
The newest generation of contact lenses feature surface treatments that may help us even combat already present inflammation. Increasing compatibility with the tear film can help stabilize the tear film as it’s challenged by device use, reducing inflammation secondary to dry eye. Time will tell as we continue to fit patients in the latest healthiest lenses on the market but in our practice, in the last year, we have yet to have a microbial keratitis secondary to daily disposable lens wear. Coincidence?
Association Between Hay Fever and High Myopia in United States Adolescents and Adults
The researchers’ objective was to investigate the relationship between hay fever and refractive error in a representative sample of adolescents and adults in the United States.
This cross-sectional study included 5,744 participants aged ≥12 years from the 2005 to 2006 National Health and Nutrition Examination Survey who participated in the allergy questionnaire, completed objective refraction and keratometry in both eyes, and had immunoglobulin E (IgE) serology. The primary predictor variable, refractive error, was classified as emmetropia (-0.99 to +0.99 diopters [D]), low myopia (-1.00 to -2.99 D), moderate myopia (-3.00 to -5.99 D), high myopia (≥-6.00 D), or hyperopia (≥1.00 D). Covariates included age, gender, race, asthma, eczema, total serum IgE ≥120 kU/L, corneal steepness, and corneal astigmatism. The primary outcome was hay fever.
The study population's mean age was 41.7 years; 48.8% of subjects were men and 51.2% were women. The prevalence of hay fever was 12.1% overall. High myopes had 2.7 times higher odds of hay fever compared to emmetropes (OR 2.67, CI, 1.57-4.51, P=0.001), which was independent of demographics, atopic conditions, IgE serology, and keratometry measurements.
The association between hay fever and high myopia identified in this large cross-sectional study remains speculative and was not mediated through corneal steepness or corneal astigmatism. Further prospective studies may help elucidate the directionality of the association between hay fever and high myopia.
