Editor's Commentary - Jason J. Nichols, OD, MPH, PhD, FAAO

These last few months have led to substantial personal and professional changes in my life and that of my wife and close collaborator, Kelly K. Nichols, OD, MPH, PhD. I'd like to make you aware of these new ventures as they will be associated with tremendous growth opportunities.

Kelly and I have recently transitioned from The Ohio State University College of Optometry to the University of Houston College of Optometry (UHCO). With Dean Earl Smith's leadership at UHCO, we have embarked on the process of creating an Ocular Surface Translational Research Center. Our desire is that this will become the leading center for ocular surface research and clinical care, with contact lenses making up a big part of this venture. We look forward to working with our old friends and new colleagues at UHCO to help grow the journal so that we continue to provide cutting edge, clinical materials in the years to come. The Ohio State University served the editors of Contact Lens Spectrum well since the publication's inception in 1986 and our Buckeye friends and colleagues will always hold a dear place in our hearts. However, big things are happening at UHCO. As always, please feel free to drop me a note at jnichols@optometry.uh.edu.

The agreement will open the Brazilian market to the Acculens scleral designs during the fourth quarter of 2011 and is optioned to expand into all of South America, Central America and Mexico.

Comfort SL is an alternative to soft lenses for the correction of non-distorted ametropic eyes, which requires only a patient Rx and K readings for the lens to be designed.

Lattice Corneal Dystrophy
By Gregory W. DeNaeyer, OD

This is a photograph of Lattice Corneal Dystrophy. This relatively rare stromal dystrophy is autosomal dominant and presents as refractile lines in the anterior stroma during the first decade of life. The lesions that create this lattice pattern consist of amyloid. As this dystrophy progresses, recurrent corneal erosions and scarring of the cornea are common. Treatments consist of bandage contact lenses or penetrating keratoplasty, depending on severity.

For more on this patient, see http://www.clspectrum.com/article.aspx?article=&loc=archive\2009\august\cls_august_a02.html .

RESEARCH REVIEW
Loretta B. Szczotka-Flynn, OD, PhD, MS, FAAO

Nystagmus and Contact Lenses

I came across a study performed predominantly at my institution on the effect of a topical carbonic anhydrase inhibitor (CAI) brinzolamide (Azopt) on measures of nystagmus foveation quality in a subject with infantile nystagmus syndrome. Dell'Osso et al (2011) concluded that the improvements in the Nystagmus Acuity Function after topical brinzolamide were equivalent to systemic acetazolamide or eye muscle surgery and were intermediate between those of soft contact lenses or convergence. In fact, topical brinzolamide and contact lenses had equivalent longest foveation domain improvements.

I wondered how contact lenses dampen infantile nystagmus syndrome? Taibbi et al (2008) noted that contact lenses allow fixation through the optical sweet spot at all times, thereby preventing distortion. They state that "contact-lenses broaden the range of high-foveation-quality gaze angles in addition to any improvement in primary-position visual acuity they may provide. This suggests that contact lenses do far more to improve visual function than has been previously appreciated and is a potentially important therapeutic option for infantile nystagmus syndrome patients." (Taibbi et al 2008)

MATERIALS & DESIGNS

Multifocal Soft Lens Update

In the realm of two-week and monthly replacement multifocal soft lenses, we have had several good silicone hydrogel products introduced in the past several years, including Acuvue Oasys for Presbyopia, Air Optix Multifocal, and PureVision Multi-Focal. These products have increased success rates when fitting presbyopes, resulting in happier patients and practitioners.

A new silicone hydrogel product recently introduced is the Biofinity Multifocal. This lens combines a successful silicone hydrogel material (comfilcon A) with a refined Proclear/Frequency 55 Multifocal design. The difference between this new lens and its predecessors is that the intermediate aspheric zone transitions into a spherical peripheral power zone such that the "D" lens has a spherical ring of near power in the periphery of the optic zone, and the "N" lens has a spherical distance zone in the periphery. This reportedly improves near vision in the "D" lens and distance vision in the "N" lens without compromising overall vision. The fitting guide also now recommends using two "D" lenses when the patient's add requirement is +1.75 D or less. This new product shows promise to further improve our fitting success with presbyopes.

An International Analysis of Contact Lens Compliance

The purpose of this study was to evaluate compliance to contact lens use in 14 countries, and to identify wearer attributes which indicate lower compliance levels.

A web-based survey was undertaken by 4021 contact lens wearers, revealing information about demographics, and lens and solution information including daily handling details, case care and aftercare frequency. Particular attention was paid to eight modifiable compliance-related behaviors which are associated with an increased risk of microbial keratitis.

Full compliance was very rare for most lens users, although better (15% of wearers) for daily disposable lenses. Reduced compliance was demonstrated in South Korea, and for young male full-time contact lens users, especially those who have not consulted their eyecare practitioner for some time. The behaviors associated with the lowest levels of compliance were rubbing and rinsing, handwashing, correct lens replacement and case cleaning.

Given other recent literature, which suggests improved contact lens compliance with regular self-review exercises, the authors encourage clinical colleagues to particularly examine case cleaning, handwashing and rubbing and rinsing at aftercare examinations, especially in young male wearers.
