OSDI = Ocular Surface Disease Index; OSI = objective scatter index; OSI-MR = OSI maintenance ratio; FVA = functional visual acuity; VMR = visual maintenance ratio; VA-BUT = visual acuity break-up time; OSI-BUV = OSI break-up value; NIBUT = non-invasive tear break-up time; LTMH = lower tear meniscus height; CFSS = corneal fluorescein staining score
