- W2083526655 abstract "The present investigation concerns the validation of testing visual performance of disposable contact lenses soon after insertion as a means of predicting their performance over their normal length of intended use. The evaluation was carried out on a group of 40 subjects over 1 week of extended wear with two contact lens types to represent Group I (SeeQuence 2™) and Group IV (Acuvue®) disposable lenses. The investigation involved the measurement of visual acuity with Logmar progression charts (Regan Contrast Sensitivity letter charts) of two different contrasts (92 % and 6%) at two luminance levels (250 and 2.5 cd/m2) and the evaluation by questionnaire of the subjejcts' visual acceptance. The results indicate the following: (i) The evaluation of the visual performance of a disposable contact lens, after 30 minutes of wear, is a reliable predictor of the performance achieved by the lens over the overall period of use for both Group I and Group IV disposable lenses. (ii) For the visual acuity (VA) evaluation routine used, involving measurements made to the nearest letter with two logMAR charts (contrasts 92% and 6 %), under two luminance levels (250 cd/m2 and 2.5 cd/m2), an overall difference of half a VA line was associated with a significant difference in subjective vision and is therefore considered clinically significant. (iii) The visual subjective acceptance of disposable hydrogel extended wear lenses was lowest at waking, a daily phenomenon not indicative of a permanent loss of performance with increased lens usage. (iv) The visual performance in terms of visual acuity and subjective visual acceptance was intrinsically higher with Acuvue than with SeeQuence 2 and remained unchaged for both lenses during the 1 week extended wear. This confirms that from a visual performance standpoint dispensing contact lenses for 1 week of wear achieved the intended objective of replacing lenses prior to loss of performance. (v) The reliability of the subjective scales used was confirmed by the results obtained for overall patient satisfaction ratings. These nonspecific ratings indicated that a greater overall satisfaction was achieved with Acuvue than with SeeQuence 2, confirming both the greater comfort and subjective vision obtained with Acuvue than with SeeQuence 2." @default.
