Gender differences in habitual contact lens wear and care patterns from a large contact lens registry
Abstracts / Contact Lens & Anterior Eye 36 (2013) e1–e15
However the two groups demonstrated no significant differences for spectacle dispense rates (P = 0.790) or average dispense values (P = 0.638). Conclusions: This study demonstrates that monthly payment plans are more advantageous in terms of practice loyalty and business model sustainability. Furthermore, the additional spend of the EyelifeTM group makes them an attractive and loyal practice builder. http://dx.doi.org/10.1016/j.clae.2013.08.028 Concordance with appropriate contact lens wearing habits in daily disposable lens wearers Sheila Hickson-Curran (MCOptom, FAAO, DipCCLRT, FBCLA) ∗ , Robin Chalmers (OD, FAAO, FBCLA), Lisa Keay (PhD), Bill Gleason (OD), Roger Albright (MBA) E-mail address: [email protected] (S. Hickson-Curran). Purpose: To describe experienced soft contact lens wearers’ wear patterns, assessment of ease of use of and degree of following wear and care instructions before and after fitting with daily disposable lenses (DD) in the TEMPO Registry (#NCT01467557). Method: Responses from 919 registered lens wearers’ electronic questionnaires were analysed for change after 4 months lens wear with Wilcoxon Signed Rank test. Comparison to ease of use with habitual lenses is described for former users of habitual lenses (n = 773). Logistic regression tested factors contributing to nonideal wear patterns after 4 months. Results: After 4 months, lens wearers dispensed DD lenses reported a significant improvement in the ease of care of their lenses (69.2% vs. 96.2% “extremely/very easy” at baseline and 4 months, respectively (p < 0.0001)) and that they were better at following instructions (67.8% vs. 90.9% “excellent/very good” at baseline and 4 months, respectively p < 0.0001) with no differences for new and experienced wearers (p > 0.2). Experienced wearers reported their DD lenses were “much/a little easier” (76.1%) to use compared with habitual lenses. After 4 months few patients reported overnight wear (89% with “never or <1 night/week”), 90% replaced lenses daily and 87% never stored then reused lenses. Sleeping in DD lenses was more common among wearers who wore their former lenses while sleeping (OR 10.6; 95% C.I. 7.1-16.0). Conclusions: This large post-market registry finds that wearers of DD lenses believe they follow instructions better than with their reusable lenses and the vast majority (≈90%) are using their DD lenses properly; replacing lenses daily, no reuse of DD lenses and no overnight wear. Wearers who wore lenses while sleeping before receiving their DD lenses were most likely to continue that behaviour and may need extra counselling during the refitting visit. http://dx.doi.org/10.1016/j.clae.2013.08.029 Gender differences in habitual contact lens wear and care patterns from a large contact lens registry Robin Chalmers (OD, FAAO, FBCLA) ∗ , Sheila Hickson-Curran (MCOptom, FAAO, DipCCLRT, FBCLA), Lisa Keay (PhD), William Gleason (OD), Roger Albright (MBA) E-mail address: [email protected] (R.

Method: At registration, self-administered electronic questionnaires from 295 males (age 35 ± 12 years) and 674 females (age 36 ± 12) were compared by Wilcoxon Signed Rank test or t-test. Gender differences in SCL wear patterns, CLDEQ-8 symptoms, assessment of ease of use, and ratings for following instructions were assessed. Results: Female SCL wearers had a significantly lower overall opinion of habitual SCLs (“excellent/very good” 36% vs. 44% males, p = 0.004), reported higher degree of dry eye (“very dry/dry” 26% vs. 18% males, p < 0.0001), and more eye sensitivity (“very sensitive/sensitive” 26% vs. 20% males, p = 0.02). Compared to males, females reported significantly higher frequency and intensity of all CLDEQ-8 symptoms; “frequent” or “constant” discomfort 23% vs. 13% males (p = 0.004), dryness 25% vs. 15% males (p = 0.0002), blurry changeable vision 13% vs. 7% males (p = 0.0006); and significantly higher intensity (4 or 5 on a 5 point scale) (p < 0.03). Wearing time was similar by gender (12.1 ± 3.7 hrs females vs. 12.3 ± 3.7 hrs for males (p = 0.3), but females reported significantly fewer comfortable hours/day (9.6 ± 4.2 hrs vs. 10.5 ± 3.8 hrs for males (p = 0.003). Habitual lens types were similar by gender (p = 0.4), both genders infrequently slept in lenses (29% males, 22% females with any EW, p = 0.8), and both believed they were complying with instructions to a similar degree (p = 1.0). Females were more likely to clean their habitual reusable lenses every day (67% vs. 56% for males, p = 0.008). Conclusions: Males generally reported a better SCL wearing experience than females in this sample, perhaps due to the female wearer’s willingness to report symptoms or tolerance to symptoms in general. Eye care practitioners should consider the wearer’s gender when counselling SCL wearers on methods to optimize the wearing experience. http://dx.doi.org/10.1016/j.clae.2013.08.030 Dry eye symptoms and plasma hormone levels A pilot study Fiona Stapleton (PhD DCLP FAAO FBCLA GradCertOcTher) ∗ , Ulrike Hampel (MD PhD), Noor Badarudin (BOptom), Isabelle Jalbert (OD PhD MPH FAAO), Michele Madigan (BOptom PhD), Blanka Golebiowski (BOptom PhD) E-mail address: [email protected] (F. Stapleton). Purpose: Dry eye symptoms are commonly reported particularly in women post-menopause. This study explored the relationship between levels of plasma sex hormones and dry eye symptoms. Method: A cross-sectional, single visit study was conducted. The study involved a convenience sample of 74 subjects without ocular surface disease, including 52 females (mean age 35.3 ± 13.4years, range 18.8-70.3) and 22 males (mean age 34.2 ± 13.8years, range 20.2-75.3). Subjects completed the Dry Eye Questionnaire (DEQ5) and numerical ratings of discomfort, dryness, foreign body (FB) sensation, burning and watering. Tear osmolarity (TearLab) and volume (Phenol Red Thread) were assessed. Venous blood was collected and plasma concentrations of oestradiol (E2) and total testosterone (TT) were determined using specific enzyme-linked immunosorbent assay. Associations were examined using Pearson’s or Spearman’s correlations, and differences between groups were assessed using independent samples t-test or Mann-Whitney U test, as appropriate. Results: Mean group E2 concentration was 65.2 ± 50.9pg/ml in females and 40.7 ± 23.8pg/ml in males; TT concentration was 0.49 ± 0.29 and 4.3 ± 1.6ng/ml respectively. Symptom reporting was higher in females (p < 0.05). Tear volume was reduced in females (p = 0.02); there was no difference in tear osmolarity. In
