Contact lenses (CLs) in Greece are widely promoted via Optician-Optometrists-Contact Lens practitioners (OOCLP) and Ophthalmologists (OPH). A pilot cross-sectional study was performed aiming primarily to evaluate the performance of monthly replacement CLs. Secondary aims include evaluation of the wearer compliance and evaluation of the role of the OOCLP/OPH on the CL patient education.
In a pilot study, 200 monthly contact lens wearers (CLW) were randomly approached and asked to complete a specially modified questionnaire. Amongst others, the knowledge, use, recommendation, information, compliance, and satisfaction of the monthly CLs were investigated. Statistical analysis was performed using Chi Square tests.
Subjects were informed about CLs mainly by OOCLP (43.5%) and friends and family (31.5%), and less by OPH (7.5%). 79.5% of the CLW bought their lenses through an OOCLP, while the rest through other sources including Internet (11.5%). SiH CLs are mainly used (41.5%) at a wearing time of 12-18 hours per day (35%), seven days per week (30%), mainly from the higher educated CLW (p=0.023). Despite the 84.5% of CLW being advised on CL wear and care, 14% of CLW admitted non-compliance, mainly by using CLs for longer than recommended (34%).Women (p=0.003), subjects aged 26-30 (p=0.043) and subjects with higher education (p=0.023) were statistically significant more compliant. Furthermore, less than half of the participants (47%) reported fully satisfied with their lenses, mainly from the lower educational groups (p=0.022), with main problems being dry eye (28.5%), CL intolerance (23.5%) and blurred vision (21%), as early as three weeks into wear (34.5%). Compliance was also highly correlated with the source of CLs: CLW were statistically significant more compliant when buying CLs (p=0.001) and receiving instructions on CL use (p=0.041) from the OOCLP rather than any other source. Finally, CLW were dissatisfied with the lack of information received by their OPH (p=0.013).
The present study suggests a decrease in monthly CL performance over the course of three weeks to a month. Significant majorities of CLW need further education from eye care practitioners, as they play a significant role in increasing CLW satisfaction in CL use and compliance.
