Abstract: : Purpose: : We conducted a survey on the occurrence of lens complaints of commercially–available one–day disposable soft contact lenses. Methods: The survey was conducted at 4 facilities during the period from October 2003 to April 2004. The subjects were 290 patients who wanted to use contact lenses and were fitted with Focus Dailies (CIBA Vision) or 1day Acuvue (Johnson & Johnson) lenses. We asked them to record any lens complaints of one–day disposable soft contact lenses in survey forms, which we collect and compile at the time of regular inspection. Results: Complaints (most frequently lens torn) were noted with the both types of one–day disposable contact lenses. The occurrence of lens complaints was 28 per 10,942 lenses (0.256%) for Focus Dailies and 20 per 5,207 lenses (0.378%) for 1day Acuvue. The causes of lens torn were: lens torn during the removal of lenses from blister packs (0.055% for Focus Dailies and 0.250% for 1day Acuvue), lens torn during the removal of lenses from the eyes (0.119% and 0.019%), initial defects at the time of delivery (0.037% and 0.040%), and lens torn during wear (0.037% and 0.080%). There were no cases of eye injury due to lens torn. Conclusions: A difference was observed in the causes of lens complaints between different brands of one–day soft contact lenses. While this survey identified no cases of eye injury due to lens torn, wearing broken lenses may be a cause of eye injury. We recommend that contact lens wearers should be instructed the proper handling of lenses according to the type of lenses they use. We would like to request to lens manufacturers that they completely prevent the shipping of lenses with initial defects through adequate quality control efforts and they develop lens torn–resistant lenses.
