Abstract
Purpose
To investigate compliance with daily disposable contact lens (DDCL) wear and investigate
re-use of lenses according to country and DDCL material worn.
Methods
Optometrists invited eligible DDCL patients from their practices to participate in
a survey on DDCL wear in Australia, Norway, the United Kingdom (UK) and the United
States (US). Eligible participants completed an online or paper version of the survey.
Results
805 participants completed the survey (96% online): Australia 13%, Norway 32%, UK
17%, US 38%. The median age was 38 years; 66% were female. Silicone hydrogel (SiHy)
DDCLs were worn by 14%. Overall, 9% were non-compliant with DDCL replacement; Australia
18%, US 12%, UK 7% and Norway 4%. There were no differences with respect to sex, years
of contact lens wear experience or DDCL material (SiHy versus hydrogels). The primary
reason for re-use was “to save money” (60%). Re-use of DDCLs resulted in inferior
comfort at insertion and prior to lens removal (p = 0.001). 75% reported occasional napping and 28% reported sleeping overnight for at
least one night in the preceding month, while wearing their DDCLs.
Conclusion
Non-compliance with replacement of DDCLs occurred in all countries investigated; the
rate was highest in Australia and lowest in Norway. Re-use of DDCLs was associated
with reduced comfort. DDCL wearers often reported wearing lenses overnight. It is
important for optometrists to counsel their patients on the importance of appropriate
lens wear and replacement for DDCLs.
