CLARITY Imaging Study: The Effect Of Cross-linked Sodium Hyaluronate On The Quality Of Optical Coherence Tomography Imaging
OCT image quality is necessary to provide accurate diagnostic information to ophthalmologists.
The increasing resolution of imaging techniques will require ever more high standards of optical transmission through the cornea and tear film.
Given that lubricant drops can improve optical transmission through the cornea, this study will attempt to quantify this.
The primary objective is to assess the effect of cross-linked sodium hyaluronate on OCT image quality compared to the effect of blinking alone.
