PURPOSE The present study aims to quantify the concentration of selected tear lipids and
proteins in symptomatic and asymptomatic contact lens wearers. METHODS Unstimulated …

Purpose. Recent studies have shown that low tear phospholipid levels are associated with
tear film instability in hydrophilic contact lens wearers. The concentration of secretory …

Purpose Despite the widespread practice of gradually adapting all new soft contact lens
wearers (neophytes), there is little evidence-based research underpinning such practice …

PURPOSE The purpose of this study was to evaluate the potential of eyelid-and tear film–
related clinical markers to be used as predictive factors for diagnosing discomfort in contact …

Objectives: To determine whether silicone hydrogel (SH) contact lens (CL) use, with or
without meibomian gland dysfunction (MGD), promotes ocular surface inflammation …

Background. Osmolarity is used to detect symptoms of dry eye disease (DED) and can be
measured using TearLab™ and I-Pen® systems. Objectives. To investigate the correlation …

Purpose.: To evaluate the levels of dinucleotides diadenosine tetraphosphate (Ap 4 A) and
diadenosine pentaphosphate (Ap 5 A) in tears of patients wearing rigid gas permeable …

Scleral lenses can affect a range of anterior segment structures including the eyelids and the
tears. The eyelids, consisting of the outer skin layer, the middle tarsal plate, and the posterior …

Dry eye is a multifactorial disease of the tears and the ocular surface that manifests with a
wide variety of signs and symptoms. It is prevalent in about 33% of the population …

Purpose To analyze quantitatively the alterations in the microvascular network of the upper
tarsal conjunctiva, lid wiper, and bulbar conjunctiva relative to ocular discomfort after contact …
