Active clinical trials for "Keratoconjunctivitis Sicca"

LacryDiag is a new Conformity European (CE) marked diagnostic imaging device devoted to the analysis of the ocular surface. It is an "all in one" device that provides 4 data: non-invasive break-up time (Non-Invasive Break-Up-Time (NIBUT) without fluorescein eye drop); height of the Tear Meniscus (TM); an infrared image of the meibomian glands; a picture of the lacrimal film by interferometry. it's performance will be compare between in diagnosing dry eye syndrome with the standard clinical evaluation, in 80 patients suffering from dry eye diseases and followed at the consultation of the Ophthalmology department of the University Hospital of Saint-Etienne.

This is a prospective, open-label, single-center, randomized, head-to-head, investigator-sponsored clinical study. It aims to investigate the vision recovery and patient comfort in borderline/mild dry eye disease patients undergoing FLACS with Premium PCIOL (i.e., Panoptix, Toric IOL (spherical/multifocal), ReStor, Symfony), receiving a 0.4mg dexamethasone intracanalicular insert when compared to patients receiving standard of care prednisolone acetate 1%.

To evaluate the clinical outcomes of the systemic re-esterified triglyceride (rTG) form of omega-3 fatty acids in patients with dry eye symptoms after cataract surgery

The objective of the study is to compare the rate of tear evaporation, measured with a novel evaporimeter, before and for one hour after an eye drop containing nano-sized oil droplets has been instilled.

Evaluate changes in tear film osmolarity and other DED signs/symptoms following treatment with IPL.

The aim of the study is to evaluate the severity of dry eye syndrome following excimer laser vision correction using no-touch all-laser photorefractive keratectomy in comparison to conventional lasik

Purpose: To develop a screening metric by examining both the characteristics of the preoperative tear film and the intracellular signaling pathways of conjunctival goblet cells in order to determine if there are certain characteristics which might predict those patients who will experience serious dry eye symptoms and complications after refractive surgery. Research Design: This study is a twelve-month prospective non-randomized investigation. Methodology: In conjunction with psychometric questionnaires and various measures of tear film quality (e.g. Schirmer's test, tear break up time, etc), impression cytology will be used to assess the intracellular signaling pathways of conjunctival goblet cells and to determine if alterations in this pathway exist. Alterations in this pathway would result in a reduced response by the mucin secreting conjunctival goblet cells thereby promoting the development of dry eye after refractive surgery.

Dry eye syndrome (DES) is a highly prevalent ocular condition inducing an inflammatory response on the ocular surface. Common symptoms include ocular discomfort, visual impairment and instability of the tear film with potential damage to the ocular surface. In addition, an intact tear film is important to provide a smooth optical surface, to act as a barrier to pathogens, to nourish the epithelial cells of the ocular surface and to prevent exsiccation. Alterations in the tear film composition, which can have their origin in several conditions, lead to tear film hyperosmolarity or instability resulting in DES. Regardless of the cause of DES, chronic dryness of the ocular surface leads to an increased susceptibility to oxidative stress, which is triggered by reactive oxygen species (ROS). This results in cell damage and activation of the immune system, keeping up inflammatory processes . In order to prevent ROS damage, several micronutrients such as vitamin C, E, and certain carotenoids, omega-3 free fatty acids, flavonoids and minerals have been used because of their antioxidant capacities. Based on this knowledge the potential of these antioxidant dietary supplements has been discussed as a treatment option for DES. Preliminary data support the hypothesis that antioxidant supplementations, in particular, supplementation with omega 3 fatty acids may be beneficial for patients with DES. The purpose of the present study is to test the hypothesis that treatment with dietary supplements improves subjective and objective symptoms of DES.

The purpose of this study is to evaluate the safety, tolerability, and efficacy in topical administration of differing dosing regimens of ISV-101 (Bromfenac in DuraSite® ophthalmic solution) compared to Vehicle and DuraSite alone.

Dry eye syndrome (DES) is a highly prevalent ocular condition with severe consequences for the patients reaching from ocular discomfort in its simplest form up to visual impairment and corneal ulceration in severe cases. Data from epidemiological studies indicate that DES is a common disease, especially in the elderly population, affecting up to 20% of adults aged 45 years or older. Topical lubricants are a mainstay of therapy, but data on its effect on tear film thickness and the corneal residence time are lacking. Recently, a new objective method for assessment of tear film thickness by optical coherence tomography has been developed. The present study aims to investigate the corneal residence time of an established topical lubricant compared to placebo in patients with DES and healthy controls.
