Editor's Commentary - Jason J. Nichols, OD, MPH, PhD, FAAO
What modality of contact lens do you fit most often in teenagers? How much does replacement schedule matter in this patient population, compared with other things like material selection? As has been well studied, we know that contact lenses make a tremendous impact in and of themselves in the teenage population (see this week’s abstract for yet another confirmation of this), but some of these other issues are not as well addressed in the clinical literature. As always, we would like to hear your thoughts on these issues. Please email us at cltoday@pentavisionmedia.com.


Global Specialty Lens Symposium
Award of Excellence

The GSLS Award of Excellence is given annually to a distinguished clinician, scholar and/or scientist to recognize their life-long achievements in the field of contact lenses, especially as they relate to specialty contact lenses. The individual selected is one whose career contribution to the field of contact lenses, including development, practice, translation of knowledge and education, and scholarly activity, all of which moved the field forward in seminal ways.

This year the GSLS recognized four Scleral Lens Pioneers, each of whom played a significant role in modernizing designs, fitting techniques and patient management at a time when scleral lenses were thought of only as a footnote in history books. Edward Bennett, OD, MSEd presented awards recognizing Don Ezekiel (Australia), Ken Pullum (United Kingdom), Perry Rosenthal, MD (USA) and Rients Visser (The Netherlands). Lynette Johns, OD, FAAO accepted the award for Dr. Rosenthal and Ron Beerten, BOptom, FAAO, FBCLA, FIACLE and Marco van Beusekom, BOptom, FBCLA, FIACLE accepted for Rients Visser.

Contamac and Brien Holden Vision Institute Enter Into License Agreement for Myopia Control

Contamac Ltd. and the Brien Holden Vision Institute have entered into a multi-year license agreement, which enables Contamac to commercialize and distribute customized silicone hydrogel and GP contact lens products based on utilizing Background Intellectual Property on myopia control from the Brien Holden Vision Institute.

Under the license, Contamac will begin to commercialize specialized contact lenses designed to reduce the rate of myopia progression in children by sublicensing the Contamac designs to key strategic partners within its existing customer base throughout the world, commencing in May 2015. The technology licensed by Brien Holden Vision Institute includes numerous U.S. and foreign patents.

Currently, a myopia control indication for use submission to the U.S. FDA is to be completed in early 2017 as part of Contamac’s commercialization plan.

Paragon Executes Global License for Scleral Portfolio

Paragon Vision Sciences executed a worldwide license agreement with KATT Group, Inc. as the exclusive GP material and marketing partner for the ICD Family of Lens Designs, a scleral lens design portfolio with diameters of 14.5mm, 16.5mm and a toric design, manufactured in Paragon HDS 100.

The ICD Family of Lens Designs was developed by John Mountford, Dip. App. Sc., FAAO, FCLSA; Don Noack, Dip. Opt. (W.A.); Randy Kojima, FAAO, FOAA and Robert Heavyside, President of KATT Group, Inc. ICD addresses the need to fit corneas with conditions ranging from post-keratoplasty, keratoconus, kerato-globus, pellucid marginal degeneration, post refractive surgery to normal shaped corneas. The simplified fitting approach that ICD employs, combined with Paragon HDS 100 (ISO 100 Dk), will benefit novice to expert scleral lens fitters and patients alike, according to the company.

ICD is fit using an 18-lens diagnostic fitting set and is manufactured by authorized ICD Laboratories worldwide. Currently, ABB Optical Group, Valley Contax, Lenticon Laboratories in Madrid, Portugal, Chile and Spain, LCS (Laboratoire Contact Service) in France, No. 7 Contact Lenses in the UK, Soflex in Israel, and T.S. Lenti a Contatto s.r.l. in Italy are Authorized ICD Laboratories. ICD clinical training is available at www.ICDLENS.com along with a complete listing of Authorized ICD Laboratories and their contact information.

To support patient training and education of scleral contact lenses, www.scleralcontactlens.com was created to provide consumers with a resource for scleral lens application and removal, and to promote proper care and handling of scleral contact lenses.

This image represents a Pellucid Marginal Degeneration (PMD) cornea with more than 14.0 diopter of astigmatism and notable inferior thinning. The patient was fitted with a scleral contact lens that provides him 20/25 corrected vision. Note the thickening of the pre-corneal tear layer over the pupillary area.

We thank Boris Severinsky for this image and we welcome photo submissions from our other readers! It is easy to submit a photo for consideration for publishing in Contact Lenses Today.

Handouts for Patient Education

It is common knowledge that good patient compliance with contact lens (CL) wear and care is vital in preventing infection. In addition, astute practitioners are always searching for new methods to help them educate their patients on this topic. Here are two printable patient handouts developed by the Centre for Contact Lens Research (CCLR), Waterloo, Ontario.

Eye Makeup Tips for People Who Wear Soft Contact Lenses:

The only clarification that I would make is that some scleral CL patients should apply their mascara first, since the wand may inadvertently touch the front surface of their protruding lens.

When Lenses Are Solutions

Contact lens comfort has been our Achilles heel for decades. Back in the days when Thimerosal was innovative, contact lens solutions drove patients nutty. Now our solution partners have innovated things to astronomical lengths, but even so, solutions bring with them additional challenges. When we encounter patients in our offices and deal with contact lens comfort, we often turn to a new lens or solution to bring about a comfort fix.

May I offer two new modalities? First is Orthokeratology. With Ortho-K we eliminate the wear time during which patients are most uncomfortable. If a patient is uncomfortable with their lenses, it usually signals a problem that can be quickly resolved. For other patients, simply consider a solution that doesn't need a solution. Daily disposables not only eliminate the need for solutions, but many of the newer era of lenses have additional features embedded on the surface that bring about added comfort benefits.

So when you encounter a problem that might be the solution, consider resolving your problem with lenses; it's the new solution.

Daily Disposable Contact Lenses vs. Spectacles in Teenagers

The purpose of this study was to compare clinical and subjective quality-of-life (QoL) data for teenagers wearing daily disposable contact lenses or spectacles.

This open-label study randomized subjects (aged 13 to 19 years) with no previous contact lens wear experience to nelfilcon A (Dailies AquaComfort Plus) contact lenses or spectacles for 6 months. A full clinical workup, as well as subjective QoL measures using the Pediatric Refractive Error Profile and Quality of Life Impact of Refractive Correction questionnaires, was conducted at baseline and at week 4 and months 3 and 6, with an additional study visit at week 2 for subjects randomized to wear contact lenses.

A total of 110 teenagers were enrolled in the study; 13 discontinued before study completion, 10 (17.5%) from the contact lens group and 3 (5.7%) from the spectacle group (p = 0.04). Visual acuity was good for both groups at all study visits. Biomicroscopy assessments were similar at baseline for both groups. Significant differences in Pediatric Refractive Error Profile responses were noted between vision correction groups across visits for appearance (p < 0.001), satisfaction (p < 0.001), activities (p < 0.001), peer perception (p = 0.003), and overall score (p < 0.001). For Quality of Life Impact of Refractive Correction, the contact lens group gave more favorable responses than the spectacle group (p = 0.02). After 6 months of wearing contact lenses, teenagers had a more positive attitude toward comfort, vision, and safety with contact lenses. No serious adverse events were reported during the study.

The daily disposable lenses used in this study are suitable for vision correction for teenagers, offering improvements in QoL measures during the first month of wear, including appearance, satisfaction, activities, and peer perceptions, without negatively impacting vision or eye health. Teenagers were able to handle contact lenses with the same amount of confidence as spectacles.
