Survey Shows Monthly Replacement Contact Lens Wearers Report a Decrease in Wearing Comfort over the Course of a Month

Monthly replacement contact lens wearers notice a decline in lens performance in weeks three and four of wear, a new survey sponsored by Johnson & Johnson Vision Care, Inc. reveals. Findings from the research among monthly lens wearers in France, in which 20 different brands of lenses were represented, show a decrease in wearing comfort over the course of a month, with no significant differences between wearers of hydrogel and silicone hydrogel monthly replacement lenses. Per the company, data was analyzed for a total of 434 existing contact lens wearers who completed an online survey. Of these, 271 were wearing monthly replacement hydrogel lenses and 163 wore monthly silicone hydrogel lenses.
     About seven in ten monthly silicone hydrogel (71 percent) and hydrogel (68 percent) wearers reported a decrease in wearing comfort as the month progressed. Asked which week of the month, in general, they start to notice that their lenses become more uncomfortable, 95 percent said they become aware of discomfort in weeks three and four. Monthly silicone hydrogel wearers who experienced discomfort tended to notice it earlier in the lens cycle than hydrogel wearers.
     The J&J survey also queried lens wearers about their perceptions of the eye care professional's role in communicating the benefits of contact lens innovations. More than eight out of ten (81 percent) say they expect their doctor to recommend an upgrade on comfort grounds, and three quarters state that they would consider seeing their eye care doctor more often if he or she would proactively propose lenses that would give them better comfort. In addition, around nine of ten (91 percent) wearers say they are more satisfied when their doctor shows them lenses that are better for their ocular health and offer more comfort.

Optometric Nutrition Society Announces Education Meeting

The Optometric Nutrition Society (ONS) will hold its first annual education meeting on October 21, 2008 in Anaheim, CA. This will be one day before the beginning of the American Academy of Optometry meeting. According to the ONS, recent studies show that consumers spend over $12 billion a year on nutritional supplements, and many patients prefer the "natural" approach to treating their eye condition. The courses for this meeting will review the role of nutrition counseling in the care and prevention of many of the eye conditions that present to the office on a daily basis.
     The agenda includes the following speakers and topics: Ellen Troyer MT, MA, Current Thoughts on Nutrition: The Latest from A-Z; Steve Whiting, PhD, Understanding the Importance and Concepts of Full Spectrum Nutrition; Stuart Richer, OD, FAAO, Inflammation and the Retina; Bruce Ames, PhD, Nutrients and Mitochondrial Health; Larry Alexander, OD, FAAO, Nutrients and Neuroprotection; and Jeffrey Anshel, OD, The Role of Nutrition in the Primary Care Practice.
     Registration is open to all members of the Society (non-members can join on the website). For details visit www.optometricnutritionsociety.org/.

Abstract: Treatment, Material, Care, and Patient-Related Factors in Contact Lens-Related Dry Eye

Researchers from The Ohio State University proposed to examine the effect of general contact lens and material characteristics, care solutions, treatment, and patient-related factors on contact lens-related dry eye. The data were derived from the Contact Lens and Dry Eye Study, designed as a cross-sectional and nested case-control study including 360 subjects. In separate statistical models, logistic regression was used to examine general contact lens characteristics, specific hydrogel lens materials, care solutions, and patient-related factors associated with dry eye status (controlled for age, gender, and current treatments).
     Several factors were significantly associated with dry eye, including treatment factors such as a recent contact lens refitting (odds ratios [OR] = 5.75, 95% confidence intervals [CI] = 2.14 to 15.46) and use of artificial tears/rewetting drops (OR = 1.09, 95% CI = 1.02 to 1.16), in addition, currently worn materials including Food and Drug Administration (FDA) group II (OR = 2.98, 95% CI = 1.14 to 6.19) and IV (OR = 1.87, 95% CI = 1.08 to 3.24). Significant patient-related factors included decreased overall satisfaction (OR = 3.57, 95% CI = 2.08 to 5.88,), dry eye in the absence of contact lens wear (OR = 6.54, 95% CI = 2.57 to 16.62), reduced daily lens wear duration (OR = 1.16, 95% CI = 1.06 to 1.26), and reduced ability to wear lenses as long as desired (OR = 2.44, 95% CI = 1.30 to 4.54). Care solutions were not associated with contact lens-related dry eye.
      They concluded that the strong association of common treatment factors with dry eye status in contact lens wearers suggests that these treatments are not entirely effective. The use of high water content materials was strongly related to dry eye in lens wearers, whereas care solutions were not. Contact lens-related dry eye was also associated with several patient-related factors such as greater ocular discomfort (without lenses), dissatisfaction, and inability to wear lenses for desired durations.

Editor's Commentary: Recommended Replacement Schedules

I clearly recall sitting at a dinner meeting where one practitioner was boasting how daily disposables are very affordable in his practice. He further explained the reason was that he prescribed daily disposables for several days of wear rather than one. There are also practitioners who recommend two week replacement contact lenses for one month of wear. Clearly, the practitioner can recommend lens replacement as he or she sees fit. I have no issue with recommending a wear schedule that is more conservative than the manufacturer's recommendation. I am not in favor of recommending a wear schedule that is longer than the manufacturer's recommended replacement though. I think this provides a confusing message to the patient who is probably not compliant anyway. I'm interested in our readers' thoughts on this.
