Available in PDF, EPUB and Kindle. Book excerpt: Purpose: Contact lens (CL) materials, modalities of wear and replacement, and care systems have changed considerably since the early studies of CL compliance were first conducted. Silicone hydrogel (SiHy) and daily disposable (DD) lenses are now the most popular lenses worn worldwide and the care systems that are currently available for them have been designed to be straightforward to use. The purpose of this research was to investigate patient knowledge of and compliance with the use of these contemporary CLs and care products, to determine whether non-compliant CL wearers experience ocular complications relating to lens wear more frequently and are more likely to discontinue lens wear, and to try to determine the factors that may constrain or enable patients to follow recommendations for appropriate lens wear and care. Methods: There are many ways in which compliance can be assessed in health care. Several different methodologies were employed during this research: A questionnaire was administered to just over 100 current lens wearers to determine whether photographic aids would help them to recognize which products they were using. More than 500 contact lens (CL) wearers were recruited by their eye care practitioners (ECPs) and mailed a questionnaire designed to evaluate their compliance with contact lens wear and care and to determine whether they had experienced any contact lens related complications which may have occurred as a result of non-compliance. Close to 5000 Current and lapsed CL wearers in Canada were recruited using Facebook to take part in an on line survey investigating CL wearing experiences during 2008 - 2010 and to establish the percentage of participants who temporarily and permanently discontinued CL wear during the period surveyed, the reasons for discontinuation and whether compliance with lens wear and care may have played a role. ECPs and patients independently completed more than 2000 linked questionnaires evaluating their contact lens wear and care. In addition the frequency with which patients attended their ECP's office for eye examinations was assessed to determine whether there was a relationship between this and their patients' compliance. More than 800 daily disposable contact lens (DDCL) wearers in four countries completed an online questionnaire designed to investigate how frequently they reused their lenses, the reasons for reuse and how the lenses were stored between uses. Quantitative (online questionnaire) and qualitative (focus groups) research methods were used to explore in detail the lens wear and care habits of adapted contact lens wearers in an attempt to seek a better understanding of what enables and constrains patient compliance with appropriate lens wear and lens care. Results: The rates of non-compliance with the wear of contemporary CLs were found to be similar to those previously reported. Non-compliance with recommendations for CL replacement was shown to be associated with a higher rate of CL related problems. CL wearers continue to "drop-out" for reasons of discomfort and dryness with their lenses but the drop out rates were not found to be different between compliant and non-compliant CL wearers. Patients who were non-compliant with lens replacement were found to attend their ECP's offices less frequently. Wearers of DDCLs were the most compliant with lens replacement; however, some did report reusing these lenses and sleeping overnight in them. Focus group participants were able to provide a greater insight into why non-compliant behaviour occurs in CL wearers with the most frequently occurring themes identified as the "consequences" that may occur if patients are non-compliant with one or more aspects of their contact lens wear and the importance of receiving "instructions" regarding the most appropriate way to wear and care for their lenses. Most of the themes that emerged from this qualitative research study were both constraints to, and enablers of, compliance. Conclusions: Compliance with contemporary CLs and care products remains poor. Non-compliant behaviour can result in serious complications and patients may not always be aware of this. Careful counseling and education on the risks associated with CL wear is required to provide patients with a better lens wearing experience and continued successful contact lens wear. ECPs and the contact lens industry can hopefully apply this greater understanding of why patients fail to wear and care for their lenses as they should and to help them develop strategies and tools to aid compliance and success in contact lens wear.

Download or read book Contact Lenses in Ophthalmic Practice written by Mark J. Mannis and published by Springer Science & Business Media. This book was released on 2006-05-11 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Even with the advances in intraocular lens technology and the growing diversity of refractive surgery techniques, the role of contact lenses in ophthalmic practice has only increased. This is due in part to the great strides in materials, technology, expanding applications (both refractive and therapeutic) for contact lenses, and the clear recognition that contact lenses will always be an important tool for the ophthalmologist. With the fitting of contact lenses as a medical art, requiring a thorough understanding of anatomy, physiology and optics of the eye, this practice is formulaic only in part. The rest of contact lens practice requires sound medical judgment and decision- making that comes only with "hands-on" experience. The authors address this need by starting with a didactic approach that incorporates frequently-asked questions and straightforward answers so that the ophthalmology resident, intermediate contact lens practitioner, and optometrist will find this to be an indispensable resource.

Download or read book Analysis of Patient Practices and Attitudes Towards Compliance with Contact Lens Storage Cases in Relation to Microbial Contamination Levels written by Sarah B. Ndedi and published by . This book was released on 2016 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Purpose: Non-compliant practices amongst contact lens wearers contribute to a high incidence of ocular complications and infections. During a contact lens-related adverse event, the infectious agent is almost always recovered from the contact lens storage case. This study measured the level of actual compliance with lens storage case hygiene, characterized the attitudes of contact lens wearers in regards to lens storage case hygiene, and correlated these factors with microbial contamination of the contact lens storage case. Since compliance is based upon patients' adherence to physicians' recommendations, this study also surveyed eye care practitioners about their knowledge of contact lens case care to identify areas of education that need to be addressed within both the practitioner and lens wearer populations. Hypotheses: 1) Certain personality traits and negative attitudes toward compliance with contact lens wear and care may be indicative of non-compliant hygiene practices and, in turn, result in higher levels of contact lens storage case contamination. 2) Recommendations by eye care practitioners regarding contact lens storage case care may be inadequate and may contribute to inappropriate care practices and low compliance rates amongst lens wearers. Methods: In the first arm of this study, a contact lens storage case drive was conducted at the University of Texas Southwestern Medical Center. During the contact lens storage case drive, participants completed anonymous, self-administered questionnaires, and submitted their used contact lens cases for analysis. Collected surveys served to characterize patient attitudes towards proper lens storage case hygiene and calculate compliance scores based on patient reported practices. The cases were then analyzed using a crystal violet assay to stain and quantify the level of biofilm (matrix of microorganisms) present within the wells. In the second arm of the study, 616 eye care practitioners were invited to complete a survey regarding their recommendations for proper lens storage case hygiene. Data summarizing the overall results of each set of surveys were compiled and statistical analyses were conducted to determine trends and correlations between variables. Results: In the patient group, 90% of individuals were deemed as having positive attitudes (score of 1 and above). The average attitude score was 10 ± 6.7 with a range of -7 to 26. Average compliance was 64% ± 20% with a range of 4-100%. Approximately 57% of subjects displayed poor compliance ( [less than or equal to] 69%), 35% average compliance (70-89%), 7% had good compliance ( [greater than or equal to] 90%), and 1.5% had full compliance (100%). No significant relationship was found between the subjects' attitude scores and compliance grades (p=0.516). The average absorbance from the crystal violet assays, used to quantify the level of biofilm, was 1.9 ± 6.5 with a range of 0.0093 to 64.1. No significant relationship was found between compliance grades and absorbance values (p=0.794). Additionally, no significant relationship was found between attitudes and absorbance (p=0.689). Certain patient attitudes and improper contact lens storage case hygiene practices reflected the reported recommendations of practitioners. Conclusions: Education about the importance of contact lens case replacement and cleaning is needed for both eye care practitioners and patients alike. Both of these educational goals could reduce the risks of infections in the contact lens wearing population.
