It seems like many more practitioners are talking about the importance of the fit of a standard soft contact lens in terms of the ultimate the success of a contact lens wearing patient. Perhaps this goes without saying, but most mass produced soft lenses are designed so as to fit the vast majority of the population. While manufacturers have data that suggest this is indeed true, a growing segment of practitioners seem to think there is more to this story. If you have a thought on this, please share it with us at email@example.com.

Ocusoft, Inc. announced the availability of two new dietary supplements specially formulated to support ocular health, Retaine OM3 and Retaine FLAX. Retaine supplements contain a unique blend of Omega-3 and Omega-6 Essential Fatty Acids, which have been reported to reduce inflammation associated with dry eye. Retaine OM3 contains high potency EPA and DHA, 800 mg and 400 mg per serving respectively, while Retaine FLAX contains flax seed oil making it ideal for individuals who cannot tolerate fish oil-based supplements.
Both supplements are conveniently packaged in blister cards to improve compliance and reduce the potential for missed doses. Retaine OM3 contains 60 softgel capsules, two taken daily and Retaine FLAX contains 120 softgel capsules, four to be taken daily or as directed by a health care professional.
Retaine OM3 and Retaine FLAX join a growing line of Retaine brand eye care products, including artificial tears, exclusively available through eyecare professionals. Introductory discount pricing is available to practitioners dispensing from their office, however, patients may also order online directly at www.ocusoft.com/retaine.
Bausch + Lomb (B+L) and Mimetogen Pharmaceuticals Inc. announced that B+L has acquired an option to license an investigational compound currently in Phase 2 development for the treatment of dry eye syndrome (DES). The compound, called MIM-D3 and developed by Mimetogen, has the potential to be the first in a new class of agents called TrkA agonists.
Currently available dry eye therapies work to increase tear production, but do not address tear quality. MIM-D3 stimulates the production of mucin, which plays a critical role in the protection and overall health of the ocular surface. Mucins are essential for lubrication; the removal of allergens, pathogens, and debris; and corneal epithelial healing to reduce ocular surface damage. Also, according to the companies, MIM-D3 may have additional benefits than currently available dry eye therapies including the potential to improve neural function, which may improve corneal sensitivity and integrity.1
Phase 2 study results for MIM-D3 demonstrated that the use of MIM-D3, dosed twice a day, results in consistent improvements across multiple dry eye signs and symptoms with no safety or tolerability issues. A Phase 3 study is scheduled to begin before the end of 2013.
Under the terms of the agreement, Bausch + Lomb will pay Mimetogen an upfront payment as an option fee to secure the right to acquire an exclusive global license on set terms triggered by the availability of top line results from a Phase 3 study. Should Bausch + Lomb choose to pursue development based on the Phase 3 results, the company will assume all development responsibilities and costs, and also will pay development milestones, sales milestones and royalty fees to Mimetogen.

Impairment of Lacrimal Secretion in Unaffected Fellow Eye of Patients with Recurrent Unilateral HK
A May 2013 study in Ophthalmology investigates the impact of recurrent unilateral herpetic keratitis (HK) on the tear secretion of the unaffected fellow eye. Thirty-five patients with a history of recurrent unilateral HK (clinically quiescent for at least 3 months) (HK group) and 35 patients who were age- and sex-matched with no history of corneal disease (control group) were included in the study. Tear osmolarity, tear break-up time (tear stability), Schirmer's I (tear reflex) and central corneal sensitivity were measured in the HK and control groups. Tear osmolarity and Schirmer's I were similar between the affected and unaffected eyes of the HK group. Corneal sensitivity and TBUT were statistically lower in the affected eyes compared with the unaffected eyes in the HK group. The central corneal sensitivity of unaffected eyes in the HK group was not significantly different from that in the control group. The TBUT and Schirmer's were decreased and tear osmolarity was increased in the unaffected eyes of the HK group compared with the control group. The authors conclude that tear function is impaired in the unaffected eyes of patients with unilateral recurrent HK, even when the disease is apparently quiescent and that HK induces a reduction in the afferent pathways of the tear secretion reflex from the affected eye, leading to tear dysfunction in the unaffected eye.1

Two New Daily Disposable Contact Lenses
"These are the most comfortable lenses I have ever worn." This is a statement I have heard often from patients lately, as two new daily disposable (DD) contact lenses have recently been launched in the United States. Certainly we welcome the new technology that leads to better comfort, but the ultimate benefit to both practitioner and patient is the change to a DD modality, the replacement frequency shown by science to have the highest rates of compliance and lowest rates of infection.1,2 The features of the two new lenses are as follows.
Biotrue ONEday (nesofilcon A, Bausch + Lomb) was the first of the two to debut in the U.S. With its Dk of 42 it is among the most oxygen permeable of the HEMA lenses. With a low modulus of elasticity (0.49) and a high water content (78%) it is a very comfortable lens. The lens also contains a UV blocker and a B+L's High Definition Optics.
Dailies Total1 (delfilcon A, Alcon) launched last month. It contains a silicone hydrogel core with a water content of 33% and a Dk of 140. On its surface, its water content exceeds 80%. This is achieved by a structure that binds water and cross-linked polymeric wetting agents that form a soft, hydrophilic surface gel, resulting in increased comfort.3

Compliance and Hygiene Behavior Among Soft CL Wearers in the Maldives
Significant levels of non-compliance and poor hygiene among contact lens wearers have been reported previously from different parts of the world. This survey aimed at identifying the scope of hygiene and non-compliant behavior of soft contact lens wearers in the Maldives.
Established soft lens wearers attending two eye clinics in Male' city, were interviewed in office or via telephone. A set of interviewer-administered questions was used to access the subjective response on compliance and hygiene behavior (hand and lens case hygiene, water exposure, adherence to lens replacement schedule, dozing and overnight wear, awareness of aftercare visits and reuse of disinfecting solution). Participants were also asked to rate themselves as a contact lens user based on their perceived compliance and hygiene practices.
Out of 107 participants, 79 (74.8 percent) were interviewed in the office and the rest via telephone. The majority of lens wearers were female, office workers and students, with a mean age of 20.64 +/- 4.4 years. Mean duration of lens wear was 28.04 +/- 8.36 months. Most of them were using spherical lenses (86.9 percent) on a daily wear basis (96.3 percent). Major reported forms of non-compliance were poor hand hygiene (60.7 percent), lack of aftercare awareness (39.3 percent), water exposure (35.5 percent) and over-use of lenses (24.3 percent). While females were more likely to overuse their lenses than males (p < 0.005), other socio-demographic factors were not associated with reported non-compliance. Although around 90 percent of the participants considered themselves average or good contact lens wearers, most exhibited some form of non-compliant and poor hygienic behavior.
The authors concluded that a significant number of Maldivian contact lens wearers exhibited poor levels of hygiene and compliance with contact lenses and lens care systems. An effective educational reinforcement strategy needs to be developed to modify lens wearers' non-compliance.
