Allergan Announces Availability of Restasis MultiDose
Allergan plc announced the availability of Restasis Multidose, which is the same preservative-free Restasis formulation, but now offered in a multidose bottle. Restasis Multidose is an FDA-approved, preservative-free, prescription eye drop. Since its launch in 2003 until now, Restasis was accessible only in single-use vials.
Restasis helps increase your eyes' natural ability to produce tears, which may be reduced by inflammation due to chronic dry eye. Restasis Multidose is designed with a patented unidirectional valve and air filter technology. The new multidose bottle uses less plastic than a package of single-use vials and will be available for the same price.
Allergan offers eligible Restasis Multidose patients a savings program called My Tears, My Rewards, which helps patients save on each prescription. For more information on the savings program and to determine eligibility, visit www.Restasis.com/savings or call 844-4MY-TEARS.

B+L Launches Ultra for Astigmatism, Announces Leadership Changes
Bausch + Lomb (B+L) has launched Bausch + Lomb Ultra for Astigmatism contact lenses, a monthly silicone hydrogel lens that combines MoistureSeal technology and OpticAlign design, engineered for stability to promote a successful first fit.
B+L says that the MoistureSeal technology helps to maintain 95% of lens moisture for a full 16 hours through a two-phase polymerization process. The OpticAlign design was developed after extensively analyzing, testing, and optimizing numerous lens geometries to determine which performed best with the Bausch + Lomb Ultra contact lens material. The design also features spherical aberration control optimized in both axes to help reduce halos and glare, according to B+L.
Bausch + Lomb Ultra for Presbyopia lenses are manufactured in samofilcon A (46% water) materials, which has a Dk/t of 114 at the center of a –3.00D lens. Parameters include 8.6mm base curve, 14.5mm diameter, spherical powers of plano to –6.00D in 0.25D steps, and cylinder powers of –0.75D, –1.25D, –1.75D, and –2.25D in axes of 10º to 180º in 10º steps. Spherical powers up to –12.00D will be available later this year.
In unrelated news, B+L announced several changes to its management team that the company says are designed to improve operational efficiencies and foster potential synergies to drive growth.

What percentage of your contact lens dropouts do so because of contact lens discomfort?
Celia de Lourdes Feliciano, OD, Santa Isabel, Puerto Rico
A patient came into my office because she had been suffering from blurred vision, tearing, photophobia, and ocular pain for several days. After examination, she was diagnosed with herpes simplex keratitis. The patient was referred to a cornea specialist, and I did the follow up. Because she had a big dendrite, I titled the picture “Medusa in the cornea.”

CARE SOLUTION CORNER

The March 17 Combined Meeting of the Ophthalmic Device Panel and the Risk Communication Advisory Committee
On March 17, the U.S. Food & Drug Administration held a joint meeting between the Ophthalmic Device Panel of the Medical Devices Advisory Committee and the Risk Communication Advisory Committee to discuss the apparent increases in misuse-related adverse events reported with hydrogen peroxide care systems, according to a review over 2015 and 2016. The data presented to the panels indicated a total of 370 reports of misuse since 2007, with about half occurring in 2015 and 2016.
Forty-five percent of patients reported accidental exposure to hydrogen peroxide solution, and another nearly 29% admitted to failing to follow the neutralization step. Ten percent admitted purchasing the wrong product. They also determined that while exposure of hydrogen peroxide in the eye was painful, the long-term clinical outcomes were relatively minor, with the FDA reporting that 57% reported burning sensation and 50% reported chemical eye burns. Another 21% reported hyperemia, superficial punctate keratitis, injection, or epithelial erosion. Nearly 90% either didn’t report on the recovery or recovered from the insult. Even panel members who use peroxide systems for lens care reported that they had had misuse experiences that were unreported. They agreed that most exposure resolves without sequelae.
It raises the question of what can be done to address the events caused by misuse. The general discussion from members of the panel indicated that they felt that the reports of misuse of peroxide systems, although under-reported, were relatively rare. However, it does raise cause for concern. The objective was to discuss additional measures to mitigate the potential risk of these exposures. To that end, the panel discussed various questions regarding current labeling, strategies to reduce risk during purchase, strategies to reduce risk once purchased, and ways to promote improved compliance.
The main takeaway from the meeting was that eyecare practitioners can do a better job in their communication to patients. However, given the paucity of data indicating that these misuse events cause a significant health risk, the panel agreed that more extensive measures are not needed. Several panel members noted that providing a substantial educational campaign on an issue that does not result in adverse sequelae detracts from the attention of patients and practitioners regarding compliance issues that do have potential for lasting ocular effects.

No One Have Ever…
We all know those patients who just aren’t happy. The “my vision is so crisp in my glasses but no one can get my contact lens vision as good as it is with glasses” patients. The “needy patients” who should stop complaining; they see 20/20 with their contact lenses, and you just want to ask “What’s your problem?”
When we refract these patients, they might have a half a diopter or maybe even three-quarters of a diopter of cylinder. However, they have never tried wearing toric contact lenses because prior practitioners never thought those lenses were ideal for them.
I believe that we all run the gamut from sane to crazy, and we are all a little weird. From the acceptance of “good vision” to the need for “crisp vision,” we all find ourselves somewhere along this spectrum. Frankly, a patient who wants clear vision may just be on the spectrum of desiring crisp vision, and it is probably not that much to ask.
If our patient in question really has some low amount of astigmatism, finding the solution may be easier than we think. In addition to our readily available soft toric lenses on the market that correct for –0.75D of cylinder, we also have lenses that go down to –0.50D of cylinder available to us. Although we may not elect to use them on hundreds of patients each year, those lenses may be just what the practitioner (and patient) ordered for a patient who has –0.50D or –0.75D of cylinder.
Now, I know what we are all thinking: “Really? Correct someone who has low cylinder like that? What a hassle. They can suck it up. That much cylinder isn’t that much of a big deal.” You may be right, but you may “not a big deal” yourself out of contact lens wearers as they seek a good provider who can fix their problem.
When a patient tells us “no one has ever…,” it’s best to make sure they don’t continue saying that when they leave your office.
A Link Between Tear Breakup and Symptoms of Ocular Irritation
In this study, the authors used the presence or absence of a soft contact lens (CL) as a barrier to test the hypothesis that tear breakup (TBU) presents a direct noxious stimulus to the ocular surface.
Ten subjects kept one eye open as long as possible–termed sustained tear exposure (STARE)–for 10 consecutive trials while discomfort was monitored with and without a CL in place. The area of TBU was quantified in each frame. Discomfort was measured during and after each STARE trial, and symptoms of ocular irritation were assessed before and after all testing.
The study found that TBU increased at the end of trials to an average of 19.89% ± 17.91% and 20.58% ± 15.33%, and discomfort increased to 9.09 ± 1.44 and 1.97 ± 2.19 in trials without and with a CL, respectively. Discomfort was significantly higher during trials without CLs (Friedman test, p < 0.005), but there was no significant difference in the area of TBU between trials (Friedman test, p = 0.296) with and without a CL (Friedman test, p = 0.527). Discomfort after each STARE trial increased significantly across trials (Friedman, p < 0.005). Symptoms of ocular irritation increased significantly from pre- to post-testing (Wilcoxon signed rank test, p < 0.005).
The authors concluded that TBU during STARE trials was associated with increasing ocular discomfort, which was partially blocked by wearing a CL, supporting the hypothesis that TBU directly stimulates the corneal surface. Repeated STARE trials led to increasing discomfort and dry eye–like symptoms of ocular irritation, suggesting that repeated bouts of TBU can lead to alterations in ocular surface sensory processing.
