The October issue of Contact Lens Spectrum is our annual specialty contact lens issue and it is a highly anticipated issue indeed. The area of specialty contact lenses has really grown tremendously in clinical practice over the last several years, in large part due to new contact lens materials and/or designs. For those activing practicing in this area, there is no doubt that these advanced contact lenses have a tremendous impact on patients’ quality of life.

J&J to Acquire Abbott Medical Optics
Johnson & Johnson announced a definitive agreement to acquire Abbott Medical Optics (AMO), a wholly-owned subsidiary of Abbott Laboratories, for $4.325 billion in cash. AMO reported sales of $1.1 billion for 2015. The acquisition will include ophthalmic products in three business segments: cataract surgery, laser refractive surgery and consumer eye health.
AMO is a global leader in ophthalmic surgery and is known for world-class intraocular lenses used in cataract surgery. In addition to the cataract business, AMO has advanced laser vision (LASIK) technologies designed to enhance surgeon productivity and correct near sightedness, far sightedness, and astigmatism. The acquisition also includes AMO’s consumer eye health products – over-the-counter drops for dry eye, as well as multipurpose solutions and hydrogen peroxide cleaning systems for patients who wear contact lenses.
The transaction is expected to close in the first quarter of 2017 and would be modestly accretive immediately to adjusted earnings per share. The closing is subject to antitrust clearance and other customary closing conditions. Following the expected closing, sales will be reported in the Medical Devices segment as a separate platform within Vision Care.
Optovue Launches Vault Mapping for Scleral Contact Lens
Optovue introduced Vault Mapping for all iSeries optical coherence tomography (OCT) systems this week at the International Vision Expo West. The new Vault Mapping software can be used to assist in scleral lens fitting by allowing visualization and mapping of the central corneal clearance (CCC). Traditional corneal imaging for identifying the clearance between the cornea and a scleral lens utilizes a fluorescein solution and a slit lamp, which results in one cross-sectional view. With Vault Mapping, a CCC assessment map is created, and the clearance pattern can be used to help determine if the lens is tilting or fitting improperly.
Optovue also introduced its proprietary AngioVue Imaging System, which provides essential OCT imaging along with OCTA that quickly visualizes retinal microvasculature non-invasively without the use of injection dye. For the first time, optometrists will have information about retinal vascular structures that may be integrated with other imaging results to form a more complete picture of retinal health.
Plan now to attend the Global Specialty Lens Symposium (GSLS) to be held January 26-29, 2017 at the Rio All-Suite Hotel and Casino in Las Vegas. This meeting will include insightful presentations by international experts in the field, hands-on demonstrations of cutting-edge products and valuable continuing education credits.

As health care practitioners, we are often put in a position where we need to balance the reality of what our patients actually do and what is best for our patients’ health. Swimming in contact lenses is a classic example of this. In the 2016 Olympics, where we watched phenomenal swimmers from across the globe, I am sure that there were a couple swimmers wearing the contact lenses under their swimming goggles.
Swimming pools, lakes, and the oceans are full of nasty microorganisms that have the potential to wreak havoc on our patients’ eyes. Contact lenses only make the situation worse by creating a breeding ground for microorganisms to proliferate. The most ideal situation for our patients would be to remove their contact lenses before embarking on water-related activities. Prescription goggles are certainly an option, but my experience is that few patients want to take on this cost with how little they use their goggles, in addition to the sometimes perceived compromised vision they experience.
So, what is a practitioner to do? Let’s live in the modern day my colleagues. I like to share with my patients the risks of swimming with their contact lenses. I share that their contact lenses create pretty substantial risks for infection, but if they have to wear their lenses while swimming, there are several things that they can do to reduce their risk. First, never sleep in your contact lenses after leaving the water, even for a short nap. Second, immediately after leaving the water, wash your hands with soap and water, remove your contact lenses and rinse them with MPS solution. Lastly, insert a new pair of reusable lenses—the ideal solution.
We have to live in the reality of what people are going to do and create as safe of an environment for them as possible. Here’s to safe swimming.

Care Solutions’ Relationship with Contact Lens
Contact lens discomfort is a primary reason why our patients drop out of contact lenses,1 which is why we typically ask them about how comfortable their contact lenses are during our case histories. One potential source of contact lens discomfort is inadequate contact lens wetting.2 Researchers often evaluate on-eye contact lens wetting/tear break-up time with advanced techniques like interferometry,3 but you can also estimate contact lens wetting with a slit-lamp in your practice by simply visualizing if there is a stable pre-contact-lens tear film. I have found that many clinicians recognize that there is a relationship between contact lens materials and wetting, but did you know that contact lens/care system combinations could also have an effect on wettability?4
In a recent article, Lira and Silva studied how care solutions (multipurpose and hydrogen peroxide) affect the contact angles (CA) of one hydrogel and four silicone hydrogel daily wear contact lenses.4 In general, their study found that both solution types were able to similarly decrease (higher values indicate worse wettability while lower numbers indicate better wettability) the CA of hydrogel and silicone hydrogel contact lenses, if the two materials had similar baseline CAs.4 This study also found that solutions were able to produce a larger decrease in CAs if the contact lenses had higher baseline CAs compared to the contact lenses that had lower baseline CAs, though these results were material dependent.4 Therefore, if contact lens wettability is an issue, you should not only consider the contact lens material in question, but you should also consider the prescribed contact lens/care system combination.

A number of optical methods for slowing myopia progression have been tested and are now available. However, data on real-world use in clinical use is scarce. Here, the authors present a review of the clinical outcomes for patients attending a specialist myopia control clinic at The University of Auckland Optometry School, NZ.
They report a comparative case series of 110 patients (aged 4-33 years, mean: 12.13 ± 4.58 years, 62% female) who attended the clinic between 2010 and 2014. Fifty-six were prescribed orthokeratology, 32 dual focus soft contact lenses, and 22 received advice only. Initial myopia, vitreous and axial eye length, previous myopia progression, age, number of myopic parents, and gender were not significantly different between orthokeratology and dual focus soft contact lens groups. Mean follow-up time for the orthokeratology and dual focus lens groups was the same (orthokeratology: 1.30 ± 0.88 years; dual focus lens: 1.33 ± 0.80 years (p = 0.989)). There was a significant reduction in the annualized myopia progression in both groups (orthokeratology: -1.17 ± 0.55 to -0.09 ± 017 D/yr, p < 0.001; dual focus soft contact lens: -1.15 ± 0.46 to -0.10 ± 0.23 D/yr, p < 0.001). There was no difference between orthokeratology and dual focus lens treatment efficacy (p = 0.763), nor in axial or vitreous chamber length changes after treatment (p = 0.184). One adverse event was reported over the 4-year period.
The researchers concluded that both orthokeratology and dual focus soft contact lenses are effective strategies for targeting myopia progression in the clinic. They saw no significant difference in the efficacy of the two methods in this regard, and so they believe there are very few barriers for any contact lens practitioner to be actively promoting myopia control treatment to at-risk patients.
