Filter by:The purpose of this study is to evaluate the efficacy and safety of PRO-148 ophthalmic solution compared with SYSTANE ® ophthalmic solution for the treatment of signs and symptoms of mild-to-moderate dry eye syndrome.
The study objective is to evaluate the long-term treatment effectiveness for adult patients with meibomian gland dysfunction (MGD) and evaporative dry eye by: 1) comparing the LipiFlow® System to a standardized daily warm compress and eyelid hygiene control therapy over a duration of 3 Months; and 2) evaluating the LipiFlow® alone and in combination with other MGD and dry eye treatments over a duration of up to 12 Months. This is a post-market, non-significant risk, prospective and multi-center clinical trial divided into two stages. The first stage from enrollment to 3 Months is an open-label, randomized controlled design to compare the effectiveness of a single LipiFlow® System treatment to a standardized daily warm compress and eyelid hygiene Control therapy with Crossover LipiFlow® treatment of the Control subjects at 3 Months. The second stage, occurring between 3 and 12 Months, is an observational design to evaluate the effectiveness of LipiFlow® alone and in combination with other MGD and dry eye treatments over a duration of up to 12 Months. Subjects are entered into the following subgroups based on the subject's self-assessment of the adequacy of symptom relief and protocol-defined criteria for additional treatment. 1. One LipiFlow® Treatment: Subjects who receive only one LipiFlow® treatment. 2. Two LipiFlow® Treatments: Subjects who receive a second LipiFlow® treatment. 3. Combination Treatment: Subjects who receive one or two LipiFlow® treatments followed by other MGD or dry eye treatment, as prescribed by the physician.
The purpose of this study is to investigate the possible effect of hinge location on corneal sensation and dry eye syndrome after laser in situ keratomileusis (LASIK).
Purpose: To establish whether there is a correlation between dry eye symptoms, age and gender, a difference in symptom intensity in different times of the day, which test (Schirmer or TBUT) better correlates with dry eye symptoms, whether it is possible to reliably use cheap, easy to use hygrometer in everyday clinical setting, and finally whether there is statistically significant correlation between applied tests (TBUT, Schirmer and evaporimetry). Methods: Subjects: 45 in group without dry eye related symptoms, and 45 in group with symptoms. Examination included structured case history (questionnaire), slit lamp examination with fluorescein staining, periocular evaporimetry, TBUT test and Schirmer test.
The purpose of this study is to measure corneal epithelial changes in dry eye subjects using a novel lubricant eye gel.
Dry eye is a common condition that affects vision and quality of life in patients. Dry eye clinical research is limited to follow up of disease progression. Currently, most research outcomes are based on subjective patient complaints rather than objective assessment of the condition. Only few objective measurements for dry eye are available today and this is mainly the result of poor repeatability and inaccuracy. This current study aims to evaluate 2 new non-invasive imaging techniques suitable for dry eye assessment. Anterior segment optical coherence tomography (AS-OCT) is an imaging device that has the ability to image the tear meniscus of the eye in a safe and non-invasive manner. Image analysis can then indirectly determine the tear film volume. Improvements in the image resolution of these devices require a study that compares the repeatability and agreement of an older (Visante AS-OCT) and a newer instrument (Cirrus AS-OCT) which the current study aims to address. Another method of evaluating dry eye disease is a novel technique that uses functional infrared thermography to measure tear evaporation rate. This study will also establish repeatability of measurements of the ocular surface temperature which are used to calculate tear evaporation rates. Should these methods are found to be repeatable, they can be used in future clinical trials as an additional tool to investigate dry eye treatments.

This study will evaluate the safety, efficacy, and acceptability of an eye drop formulation in subjects with dry eye disease.
This study is to evaluate the safety of a new preservative in a lubricant eye drop used four times a day in healthy adults and subjects diagnosed with dry eye.
To evaluate the efficacy and safety of KCT-0809 compared to placebo in patients with dry eye syndrome.
