Purpose : To compare pre-lens non-invasive tear break-up time(NITBUT) and subjective ocular symptoms with two different silicone hydrogel lens materials.

Methods : Samfilcon A and Comfilcon A lenses were worn on the right and left eyes of 32 (23.5¡¾ 2.92 years, female: 24, male: 8), respectively. After Each subjects attended three visits (on day 1 after 3 hours: on days 1 and 7 after 9 hours of wear), visual acuity using high (100%) and low (10%) contrast chart and pre-lens NITBUT using Keratograph 5M were measured. The subjects were surveyed with questionnaire for subjective ocular symptoms in terms of discomfort, dryness, changeable vision, closing eyes and removing lenses.

Results : High and low contrast visual acuity, and pre-lens NITBUT values were not significantly different between Samfilcon A and Comfilcon A. There was no significant difference in visual acuity and NITBUT change during 7 days of wearing each lens. The relative frequency of subjective symptoms of 5 items related to wearing contact lenses was not significantly different in all items, the responses of the wearers in terms of lens preference were not statistically different (40.6%, 37.5%, respectively).

Conclusion : The study demonstrates similar clinical results for pre-lens NITBUT and subjective ocular symptoms with Samfilcon A and Comfilcon A. The two silicone hydrogel lenses could not find the difference between the two lenses in the lens wearer despite difference lens materials and manufacturers.
