![]() 9 CL compliance was targeted for improvement in past years through the introduction of multipurpose disinfection systems or multipurpose solutions (MPS) and, more recently, the vast availability of daily disposable lenses (which avoid the need for disinfection altogether). 8 The worse report yet out in the UK reported that daily wear CL use had a noncompliant behavior rate of 99.7% of the time. ![]() In comparison to CLs, noncompliance in glaucoma is reported to be 25–50%. 7 Glaucoma has commonly been reported as a disease state that is confounded by patient misunderstanding and non-adherence to pharmaceutical therapy. ![]() CL noncompliance was reviewed by a 2011 questionnaire study, and it was found to be 98% with problematic activities arising in the following order (most common first): tap water exposure, sleeping in unapproved lenses, wearing lenses beyond the manufacturer’s recommended replacement frequency (MRRF), failing to wash hands, failing to replace the lens case, and solution misuse. When education and understanding of hygiene in CL care are not the issues, non-adherence to instructions is potentially a factor. 6 It has been reported that patients forget as much as 50% of presented medical education within minutes of leaving a medical visit. 5 Worse yet, another study has found general medical noncompliance to be as high as 44%. A total of 188 million of those visits were by patients not following the advice and instructions of their providers (a noncompliance rate of 25% at a cost of $300 billion USD). 2, 4 In general medical care, there were nearly 760 million visits to physicians for medical problems in year 2000. A total of 30% of respondents to a 2003 survey considered themselves poorly prepared with regards to the proper regimen of CL care and maintenance, which is suggestive that wearers might have a lack of knowledge and understanding. 2, 3 In some instances, poor understanding of proper hygiene and care of CLs is an issue. Wearer’s inadequate behaviors such as improper cleaning, disinfection, reuse of solutions, inadequate or absent handwashing, lack of lens case replacement, and CL overwear have been proposed as causes of complications and issues with CL intolerance and failure. Patient education, handwashing, compliance with care, and wearing schedule are some of the challenges that providers face in the care of CL patients even today.Ĭontact lens (CL) fitting success has many times been jeopardized by the occurrence of complications. Despite the improvements in CLs and their care, challenges persist. CL materials have improved in recent years in an attempt to meet the challenges of dryer eyes. Patients eyes are getting dryer as factors of age and the environment. Nearly all patients (even presbyopic patients) have the option of contact lenses today given the expansion of powers and parameters in recent years. There are many activities in which patients report a preference of CL wear over spectacles (athletics for example). CLs have become one of the most commonly used medical devices in the market, with more than 40 million wearers in the US. The interest and desire to wear CLs have been stable in recent years, evidenced by the consistency of new wearers into this category of refractive correction. Contact lens (CL) wear has been a viable alternative to spectacle wear for several decades.
