Sponsor's own description
Purpose of this study was to evaluate the effect of presbyopic correction lens on Humphrey visual field (HVF) testing in patients with 2 models of multifocal intraocular lens (MIOL) both with and without glaucoma. All participants performed HVF testing with presbyopic collection lenses and without presbyopic collection lenses on the same occasion (5-10 minutes between the test). The mean deviation (MD) and pattern standard deviation (PSD) were compared between with and without presbyopic collection lenses, between glaucoma and non-glaucoma and between 2 models of MIOL.
