Vision Specific Quality of Life of Pediatric Contact Lens Wearers
ABSTRACT Several studies have shown that children are capable of wearing and caring for contact lenses, but it is not known whether the benefits outweigh the risks associated with contact lens wear. The purpose of this article is to compare the vision-related quality of life benefits of children randomized to wear spectacles or contact lenses for 3 years using the Pediatric Refractive Error Profile.
The Pediatric Refractive Error Profile was administered to 484 children who wore glasses at baseline. The children were then randomly assigned to wear contact lenses (n = 247) or spectacles (n = 237) for 3 years. The survey was administered at the baseline examination, at 1 month, and every 6 months for 3 years.
During 3 years, the overall quality of life improved 14.2 +/- 18.1 units for contact lens wearers and 2.1 +/- 14.6 units for spectacle wearers (p < 0.001). In all scales except the visual performance scales (Distance Vision, Near Vision, and Overall Vision), the quality of life improved more for older subjects than younger subjects. The three scales with the largest improvement in quality of life for contact lens wearers were Activities, Appearance, and Satisfaction with Correction.
Myopic children younger than 12 years of age report better vision-related quality of life when they are fit with contact lenses than when they wear glasses. Older children, children who participate in recreational activities, children who are motivated to wear contact lenses, and children who do not like their appearance in glasses will benefit most.

ABSTRACT: This study aims to investigate the association of compliance amongst lens wearers and lens case contamination as assessed by the microbial profile of lens cases. Fifty-two asymptomatic lens wearers filled out questionnaires seeking demographic data and several aspects of compliance to lens wear. Subsequently, contamination profiles of the inside bottom and rim of their lens cases was obtained for bacteria, fungi and Acanthamoeba. The association of the self-reported responses in the questionnaire with contamination profile of the lens case was then analyzed. Based on compliance criteria, 21% of the participants were described as fully compliant lens wearers. Contamination of lens case was prevalent in 42% of the cases. Frequent non-compliant behaviours reported by study participants included, showering and sleeping with contact lenses, and irregular lens case replacement. In comparison to soft contact lens wearers prevalence of non-compliance and contamination amongst rigid gas permeable (RGP) lens wearers was significantly greater. There was a statistically significant correlation between bacterial contamination and current case age. These results suggest that majority of lens wearers do not fully comply with recommendations for lens wear and case care. Crucially, none of the fully compliant patients had contaminated lens cases. However it would appear that several non-compliant behaviours significantly increase the risks of case contamination. These results suggest that greater efforts should be invested with lens wearers to ensure enhanced compliance as this is likely to reduce the possibility of case contamination.Contact lens & anterior eye: the journal of the British Contact Lens Association 09/2013; 37(2).

ABSTRACT: OBJECTIVE:: To compare current symptoms, compliance, ocular health, and previous adverse events between current successful long-term contact lens wearers fit as children or as teenagers. METHODS:: People who had successfully worn soft contact lenses for at least 10 years completed an online survey about demographics, current wearing status, compliance, symptoms, and previous adverse events. A subset reported for a slit-lamp examination, autorefraction, autokeratometry, and specular microscopy. Statistical comparisons were made between those fit as children (12 years or younger) and those fit as teenagers (13 years or older). RESULTS:: Of the 175 subjects completing the online survey, 86 (49.2%) were fit as children and 89 (50.8%) fit as teenagers. Those fit as children wore their contact lenses for an average of 14.8 ± 3.4 hours per day, compared with 14.7 ± 3.6 hours per day for those fit as teenagers (P=0.74). Eighteen (20.9%) fit as children and 17 (19.1%) fit as teenagers reported ever having had a painful, red eye that required a doctor visit (P=0.76). Overall, there were no differences in ocular health between the groups. Those fit as children were more myopic than those fit as teenagers (-4.30 ± 1.69 and -2.87 ± 2.75, respectively; P=0.02). CONCLUSIONS:: Successful contact lens wearers fit as children are no more likely to report previous contact lens-related adverse events, problems with compliance, decreased wearing time, or worse ocular health than those fit as teenagers, so practitioners should not use age as a primary determinant in fitting children in contact lenses.Eye & contact lens 06/2013; DOI:10.1097/ICL.0b013e318296792c · 1.68 Impact Factor
