Level of compliance in contact lens wearing medical doctors in Nepal

How Can We Better Inform Patients of the Importance of Contact Lens Compliance?: Current Perspectives

Compliance with contact lens care is important for successful contact lens wear and for minimizing the risk of complications related to lens wear. There are many components of overall lens care guidelines that may potentially be disregarded, forgotten, or misunderstood. Literature has reported copious data on rates of poor compliance for separate lens care recommendations. Knowing the areas of contact lens care where lens wearers perform poorly is helpful when creating strategies for improving patient education. As science evolves and new best-practices are determined, eye care providers must be engaged in educating new lens wearers and reeducating existing wearers. It is vital to make wearers mindful of proper lens care and why proper lens care should be important to them. Various educational strategies can help practitioners to communicate with their patients more effectively. The purpose of this narrative review is to discuss studies of noncompliance with contact lens wear; consequences of these noncompliant behaviors; and studies of lens care education which were found with a literature search. The resulting discussion also includes strategies to improve compliance with patient contact lens wear.

Attitudes and Behaviors Regarding Compliance With Contact Lens Wear and Care Among Contact Lens Users at a University Hospital in Turkey

OBJECTIVES

To investigate the level of compliance with contact lens (CL) care habits among CL wearers of different age and occupation groups.

METHODS

This survey study included 205 CL wearers followed in the tertiary reference center between 2016 and 2022. The survey was employed to probe each user's demographic data and noncompliant behaviors. To this end, the study compared CL compliance levels of patients in different age and occupation groups.

RESULTS

There were 85 (41.5%) patients in the good compliant group, 72 (35.1%) in the average compliant group, and 48 (23.4%) in the poor compliant group. The most common noncompliant behavior was disruption of aftercare visits. Except for two noncompliant behaviors (storage of fresh lens solution and exceeding the recommended lens case replacement time), other noncompliant behaviors were found more frequently in the ≤25 age group. The differences between the age groups were significant in hand washing and water activities ( P =0.004 and P =0.023, respectively). Exceeding lens replacement time and sleeping with lenses criteria were found to be significantly noncompliant in health care workers compared to non-health care workers ( P =0.006 and P =0.001, respectively). The level of compliance was found to be lower in users with 6 to 7 days of CL use per week than in those with fewer days ( P =0.006).

CONCLUSION

We found that the compliance rate was lower in younger patients and health care workers. We also observed that long-term use of CL reduces the level of compliance. Therefore, it might be necessary to focus on modifiable risk factors in these patient groups.

Knowledge and compliance with contact lens care: A population-based study at a referral center in Northeast Mexico

OBJECTIVE

Despite the increasing prevalence of contact lens (CL) wear, knowledge and compliance with proper care remain suboptimal. This study aims to assess the level of knowledge and compliance with lens care practices in patients attending a third-level institution in Northeast Mexico.

METHODS

A cross-sectional study using a self-administered online survey was conducted. Patients at the Instituto Tecnolgico de Monterrey were invited to participate. The questionnaire consisted of three sections: demographic data and CL information, CL practices, and CL care knowledge. Participants responding correctly to 6/7 questions from the second and third sections were classified as having good compliance and good knowledge, respectively. Predictive factors for good compliance and knowledge were calculated using a logistic regression model.

RESULTS

A total of 287 users participated in the study. The median age was 25 (14-78) years with a female (n = 221, 77 %) predominance. Good knowledge was observed in 215 (74.9 %), whereas only 42 (14.6 %) presented good compliance. Failing to replace CL as prescribed (n = 199, 69.3 %) and sleeping with the devices (n = 198, 69 %) were the most frequent practices causing non-compliance. Whereas prohibition of swimming with CL was the least known practice (n = 74, 25 %). Users with recent (≤5 years) wearing experience were more likely to present good knowledge (OR 2.19, p = 0.014) and compliance (OR 3.15, p < 00.01). No statistical correlation was established between knowledge and compliance.

CONCLUSION

Non-compliance and lack of knowledge of proper CL care were prevalent among in this population. Long-term CL users were at higher risk of non-compliance and lack of knowledge. Moreover, knowledge was not related to compliance; therefore, different strategies must be implemented to reduce CL misconduct.

TFOS Lifestyle: Impact of contact lenses on the ocular surface

Several lifestyle choices made by contact lens wearers can have adverse consequences on ocular health. These include being non-adherent to contact lens care, sleeping in lenses, ill-advised purchasing options, not seeing an eyecare professional for regular aftercare visits, wearing lenses when feeling unwell, wearing lenses too soon after various forms of ophthalmic surgery, and wearing lenses when engaged in risky behaviors (e.g., when using tobacco, alcohol or recreational drugs). Those with a pre-existing compromised ocular surface may find that contact lens wear exacerbates ocular disease morbidity. Conversely, contact lenses may have various therapeutic benefits. The coronavirus disease-2019 (COVID-19) pandemic impinged upon the lifestyle of contact lens wearers, introducing challenges such as mask-associated dry eye, contact lens discomfort with increased use of digital devices, inadvertent exposure to hand sanitizers, and reduced use of lenses. Wearing contact lenses in challenging environments, such as in the presence of dust and noxious chemicals, or where there is the possibility of ocular trauma (e.g., sport or working with tools) can be problematic, although in some instances lenses can be protective. Contact lenses can be worn for sport, theatre, at high altitude, driving at night, in the military and in space, and special considerations are required when prescribing in such situations to ensure successful outcomes. A systematic review and meta-analysis, incorporated within the review, identified that the influence of lifestyle factors on soft contact lens dropout remains poorly understood, and is an area in need of further research. Overall, this report investigated lifestyle-related choices made by clinicians and contact lens wearers and discovered that when appropriate lifestyle choices are made, contact lens wear can enhance the quality of life of wearers.

Compliance of Soft Contact Lens Care and Bacterial Contamination Among University Students in Palestine

PURPOSE

This study investigated the contact lens care compliance, noncompliance reasons, bacterial contamination rate, and the behaviors associated with contamination among university students in Palestine.

PATIENTS AND METHODS

133 Habitual soft contact lens wearers were recruited in this study and interviewed using a face-to-face questionnaire, to obtain data on demographics, contact lenses, modifiable lens care behaviors and the reasons for non-compliance. High, moderate, and low lens care behaviors were identified. Additionally, a sample of the participant's storage cases was collected for bacterial contamination testing.

RESULTS

The participants' mean age was 22.4±4.4, with female predominance (62.4%). The average compliance rate was 76.8%. Total CL care compliance (100%) was found in filling the case with adequate solution, not sharing the lenses or storage case with others, while the poorest compliance (>40%) was found in attending after-care visits, checking the solution's expiry, and re-disinfecting the lenses with a fresh solution before insertion after prolonged storage. Poor understanding of the instructions contributed significantly to a low level of compliance (P≤0.05). Gram-positive and gram-negative bacteria were detected in 19.55% of the participants' cases. Poor hand and case hygiene, no replacement of lens cases (monthly), and water exposure were linked to bacterial contamination of storage cases.

CONCLUSION

This study indicated moderate to high compliance in CL care, averaging 76.8%. Poor compliance was found in attending after-care visits, checking the solution's expiry, and re-disinfecting the lenses with a fresh solution after an extended storage interval. 19.55% of the cases had bacterial contamination, with Staphylococcus Aureus being the most common. Poor hand and lens case hygiene and water exposure are found to be associated with lens case contamination. These findings emphasize the importance of patient education on safer lens wear modalities, proper wearing schedules, and hygiene regimens to reduce the risks of developing contact lens complications.

Assessment of patient compliance in orthokeratology and analysis of influencing factors: a cross-sectional study

Background

Patient non-compliance, that is, failure to perform standard wear and care orthokeratology (ortho-k) lenses procedures, has been shown to be a major risk factor for contact lens-associated complications. Therefore, this study aimed to investigate the compliance with wear and care behaviors of ortho-k patients and analyze its influencing factors.

Methods

Patients who were successfully prescribed ortho-k lenses at the Eye Center of the Second Affiliated Hospital of Zhejiang University School of Medicine (ECSAHZU) were enrolled in the study. Patient compliance with wear and care behaviors was examined through a questionnaire.

Results

This study assessed 238 subjects. The subjects’ ages ranged from 7 to 25 (mean ± SD, 11.3 ± 2.5) years. The compliance with wear and care behaviors was 19.7%, and the subjects’ self-assessment compliance was 96.6%. The compliance rate of subjects wearing lenses for less than 1 year was higher than that of subjects wearing lenses for more than 1 year (p < 0.001). In the first year, the compliance rates of wearing experiences for less than 1 month, 1 month, 3 months, 6 months, and more than 6 months were 45, 29, 21.6, 20, and 27.6%, respectively, and there were no statistically significant differences in compliance among these periods (p = 0.314). No correlation was identified between compliance and age (r = − 0.061, p = 0.527) or sex (r = 0.114, p = 0. 751). There was no correlation between compliance and lens care operator (r = − 0.626, p = 0.151).

Conclusions

The compliance of ortho-k patients was poor. After wearing ortho-k lenses for more than 1 year, compliance with wear and care behaviors declined. In clinical practice, measures should be taken to solve these problems and improve the safety of wearing ortho-k lenses.

Contact lens procurement and usage habits among adults in Sudan

Objective

The study aimed to assess contact lens (CL) wear and care habits among adults in Sudan.

Design

An observational, non-interventional, multi-center, cross-sectional study was conducted in the CL departments of all the eye hospitals and centers, and optical centers in the Khartoum State, Sudan.

Participants

Established CL wearers residing in Khartoum State, Sudan.

Main outcomes and measures

CL wear profile, CL usage habits, hand and CL hygiene habits were assessed using an interviewer-administered questionnaire.

Results

The average age of the 442 participants was 24.57 (± 4.87) years. Women comprised 92% of the sample. Smoking was reported by 15.8% of the sample. 81.9% wore soft spherical CL, with 43.4% of the participants were prescribed CL on a yearly replacement schedule. Only 68.3% were prescribed CL by an eye care practitioner. Multipurpose solutions were used by 78.8% of the sample to clean CL, and by 52% to clean the lens case. Compliance rate for CL wear and care among participants was 81.1%. None of the participants reported sharing CL or CL case and rinsing the case with tap water. High compliance level was observed for overnight wear; swimming and showering with CL; handwashing before CL insertion; and cleaning of CL. Moderate compliance rates were recorded for cleaning and replacing lens case, and topping up or sharing solution. Low compliance was noted for attending after care visits.

Conclusions and relevance

CL wearers in Sudan exhibit high to moderate levels of compliance to most contact lens wear and care aspects, except for attending aftercare visits. CL practitioners in Sudan are encouraged to prescribe CL appropriate to the lifestyle and economic situation of patients and actively recommend care products. In addition, practitioners need to follow up with patients to attend aftercare appointments, where hygienic wear and care habits should be emphasized.

CLEAR - Evidence-based contact lens practice

Evidence-based contact lens -->practice involves finding, appraising and applying research findings as the basis for patient management decisions. These decisions should be informed by the strength of the research study designs that address the question, as well as by the experience of the practitioner and the preferences and environment of the patient. This reports reviews and summarises the published research evidence that is available to inform soft and rigid contact lens history and symptoms taking, anterior eye health examination (including the optimised use of ophthalmic dyes, grading scales, imaging techniques and lid eversion), considerations for contact lens selection (including the ocular surface measurements required to select the most appropriate lens parameter, lens modality and material selection), evaluation of lens fit, prescribing (teaching self-application and removal, adaptation, care regimen and cleaning instructions, as well as -->minimising risks of lens wear through encouraging compliance) and an aftercare routine.

Compliance with orthokeratology care among parents of young children in Taiwan

OBJECTIVES

To evaluate compliance with orthokeratology (Ortho-K) care and its influencing factors among parents of 6-13-year-old myopic children in Taiwan.

METHODS

Parents who are responsible for the care of the Ortho-K lenses of their myopic children were recruited through a closed Facebook peer support group to answer an online compliance questionnaire, including the wear and care behaviours and follow-up visits of Ortho-K.

RESULTS

A total of 253 online questionnaires were analysed after excluding those with wrong information. Most participants (89.7%) were mothers and had university-level or higher education (72.3%); 67.6% of them could achieve a score equal or higher than 60% correct rate on knowledge items. In addition, 39.3% of participants had high myopia (spherical equivalent ≦ 6.0 diopters). The mean age at onset of myopia was 7.75 years for children, and 57.4% wore Ortho-K lenses for less than a year. Full compliance rate was 22.8%, as reported by fathers or mothers. The compliance rate for follow-up visits significantly increased with provision of axial length information in follow-up visits, knowledge of axial length changes as an effect of myopia control, and Ortho-K use for less than 6 months. The compliance rate for wear and care was significantly associated with high myopia in one of parents, high education level, early onset of myopia in children, knowledge of Ortho-K and myopia control, and Ortho-K use for less than 6 months.

CONCLUSION

These results indicate the need for a comprehensive education programme for parents with young myopic children to ensure strict adherence to fitting and wear protocols and good follow-up of Ortho-K lenses.

Survey of hygiene, behaviours, and awareness regarding contact lens wear with conventional and novel questions

Clinical relevance: Contact lens (CL) compliance studies are beneficial to identify potential risks, take necessary measures, and issue warnings on time.Background: Understanding CL compliance is crucial to ensure that individuals maintain healthy and appropriate CL wear. The present study aims to assess knowledge and awareness about soft CLs; the degree of non-compliance among soft CL wearers; and the associations of these with demographic features.Methods: A comprehensive questionnaire composed of 44 questions was used to assess the demographic characteristics, hygiene care, habits, knowledge, opinions, awareness and experiences of 109 soft CL wearers. The survey was conducted between September 2019 and March 2020.Results: The mean non-compliance rates were: 35.4% and 11.2% for hand-washing and hand-drying; 77.8% for rubbing/rinsing of the CLs; and 37.0%, 50.5%, and 31.6% for swimming, showering, and overnight sleeping with the CLs in, respectively. Women were more compliant in manual cleaning and rinsing of the CL storage cases with lens solution (p = 0.037). Swimming behaviour with inserted CLs was significantly high among CL users with over 5 years of experience (p = 0.03). Additionally, 85% of the wearers generally found the soft CLs comfortable, and 69.8% found the cost of the soft CLs reasonable. Over 90% of the wearers spent between 0 to 5 min per day to insert and remove the soft CLs.Conclusion: Women presented with more frequent CL use, and were significantly more compliant in terms of cleaning the CL storage cases. Regardless of gender, the non-compliance of swimming with inserted CLs was significantly high among CL wearers with over five years of experience. A majority of the results of the investigated non-compliances did not depend on gender, income level, age-group, duration of CL use, and education level.

Assessment of contact lens wearers' attitude toward contact lens wear and care during Coronavirus Disease 2019 (COVID-19) pandemic: A cross-sectional online survey

AIM

COVID-19 is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Several reports have provided conflicting recommendations regarding contact lenses (CL) use during COVID-19, causing confusion among CL wearers. The aim of this study is to assess CL wearers' attitudes toward CL wear and care during COVID-19 pandemic.

METHODS

A web-based cross-sectional online survey was used to assess the participants' attitude toward CL wear and care during the COVID-19 pandemic. The survey layout was based on Google form® specifically developed for CL wearers. Demographic characteristics and CL history and profile were also collected for each participant.

RESULTS

A total of 196 CL wearers completed the online survey with an average age was 26 (± 4.1) and 90.8 % of participants were females. As reported by the participants, social media was the main source of information about COVID-19. 38.8 % of the study population reported stopping CL wear during the pandemic. The main stated reason for lens discontinuation was decreased social activities during the pandemic. 61.2 % of participants continued lens wear, with the majority reported considerable changes in their behaviors toward CL wear and care during the pandemic. This includes reinforced hands cleaning before and after lens wear, disinfecting of CLs and CL case and less frequent CL aftercare visits.

CONCLUSION

The majority of the study population have continued CL wear during the pandemic. Contact lens wearers reported profound changes in attitudes toward CL wear including improved care and maintenance. Additionally, changes in CL purchase habit have been reported with more tendency for online purchase. CL cessation has been associated with several perceived reasons mainly attributed to reduced outdoor activity and fear of ocular infection. Levels of compliance among CL wearers should be assessed and reinforced during the current pandemic and similar lockdown situation to reduce possible CL-related complications and dropout.

Level of Compliance in Orthokeratology

OBJECTIVES

To investigate the level of compliance with orthokeratology (ortho-k) guidelines and the main behaviors of poor compliance to guide clinical care.

METHODS

A questionnaire was sent to ortho-k patients in the Eye Hospital of Wenzhou Medical University (EHWMU) in Mainland China who were prescribed ortho-k lenses after January 2013 and have worn ortho-k lenses for more than 1 year to determine the compliance rate for eight wear and care behaviors. Follow-up visit compliance was then investigated among these patients using a retrospective survey.

RESULTS

A total of 1,500 questionnaires were distributed, and 405 patients responded. The mean age of the patients was 13.1±3.9 years (range 9-22 years); 60.5% of the patients were female, and 98.3% were younger than 18 years. The full compliance rate was 14.1%, the compliance rate for wear and care behaviors was 18.5%, and the compliance rate for follow-up visits was 63.3%. The three highest noncompliance categories for wear and care behaviors were exposure to nonsterile solution, not removing lens depositions according to the eye care practitioners' (ECPs) recommendations and inadequate hand washing. No correlation was observed between the compliance for wear and care behaviors and age, sex, and wearing experience. The follow-up visit compliance rate significantly decreased from the third month to the ninth month. The common reasons for discontinuing follow-up were lack of time, no symptoms, and inconvenience.

CONCLUSIONS

The level of compliance with ortho-k lens wear in Mainland China is not high, necessitating ECPs to stress to patients the details of wear and care behaviors, especially avoiding exposing lenses to nonsterile solution. Improving monitoring of follow-up visits, particularly within the first 9 months of wearing ortho-k lenses, is needed.
