” from contact lens (CL) wear continues to afflict the CL industry. This study was conducted to determine whether the advent of new CL materials and designs has impacted the dropout
rate and the reasons for discontinuation
Current and lapsed
CL wearers residing in Canada were recruited using Facebook to take part in an on line survey investigating CL wearing experiences during 2008 to 2010 and to establish the percentage of participants who temporarily and permanently discontinued CL wear during the period surveyed.
Four thousand two hundred seven eligible surveys were received (64% female; median age 27 years). Forty percent had lapsed
from lens wear for at least 4 months; however, 62% of the lapsed
wearers (LWs) resumed wear. There were no differences between LWs and nonlapsed wearers (NLWs) with respect to gender; however, LWs were older, started lens wear when older, and had not worn lenses for as long as NLWs (all P
<0.001). More NLWs than LWs wore silicone hydrogel
CLs (49% vs. 38%, P
<0.001) and more LWs than NLWs wore daily disposable
lenses and hydrogel CLs (24% vs. 19% and 22% vs. 18%, respectively, P
≤0.001). Primary reasons for discontinuation
were discomfort (24%), dryness (20%), red eyes (7%), and expense (7%). Compliance
with lens replacement was no different between LWs and NLWs (48% vs. 45%).
About 23% of those surveyed had discontinued CL wear permanently. The primary reasons for dropping out continue to be discomfort and dryness. Dropout
rates were lower in silicone hydrogel
