Filter by:The DRy eye Outcome and Prescription Study (DROPS) is a large observational multicentre study exploring the 'real world' effectiveness of artificial tears in dry eye disease and determinants of efficacy. The aim is to include at least 635 symptomatic dry eye patients who are prescribed artificial tears. All trainees and fellows in London are invited to become collaborators: collaborators are asked to consent patients, assess signs at baseline, and give patients questionnaires at baseline and 4 weeks (for home completion). In tandem, we are conducting a qualitative review of ophthalmologists' prescribing behaviours for dry eye disease.
AZ201801 is a multicenter study of AZR-MD-001 ointment and AZR-MD-001 vehicle in patients with Meibomian Gland Dysfunction (MGD) and evaporative Dry Eye Disease (DED)
Today, cataract surgery has become one of the safest and most effective eye surgical procedures performed on many people through the development and development of surgical techniques and instruments. However, a significant number of patients who underwent cataract surgery still complain about postoperative symptoms, such as irritation, pain, dryness, burning sensation, and foreign body sensation. The reasons of dry eye (DE) development after cataract surgery include thermal and light toxicity from the microscope, corneal epithelial damage, and frequent irrigation of ocular surface during operation, sterilization of conjunctival sac and eyelid with chemicals, transection of the corneal nerves by corneal incision, use of topical anesthetics, and preservatives in topical eye drops. In this era of high expectation of patients and premium intraocular lenses, the postoperative discomforts cannot be accepted to many patients. Several studies have recently reported that the common cause of postoperative symptoms of the patients is DE. Furthermore, if the ocular surface is deformed due to DE syndrome after surgery, the optical quality is greatly affected which results in a decrease of the quality of vision. If the tear film becomes irregular, the higher-order aberration can change due to local irregular total radius of curvature of ocular surface and result in decreased visual acuity. There have been many attempts to treat DE syndrome after cataract surgery. Artificial tears are commonly used for the first line treatment of postoperative DE and several studies revealed its effectiveness on management of DE symptoms and signs. The postoperative use of cyclosporine 0.05 % topical eye drop improved DE symptoms and visual quality after cataract surgery. Recently, diquafosol sodium ophthalmic solution has been used for the management of DE after cataract. Diquafosol is a dinucleotide derivative and functions as agonist to the purinergic P2Y2 receptor. Diquafosol is known to stimulate not only the mucin secretion from the goblet cells but also water secretion from conjunctival epithelial cells and accessory lacrimal glands. According to previous studies, diquafosol has been found to be very effective in treating DE after cataract and to alleviate symptoms of DE syndrome. Furthermore, several studies have shown that topical diquafosol has a better efficacy in managing DE after cataract surgery than artificial tears. The preservative free diquafosol ophthalmic solution has been released recently. The use of eye drops without preservatives has also been shown to play an important role in the treatment of DE after cataract surgery. Until now, there is no study that evaluated the effect of preservative free diquafosol ophthalmic solution. Thus the investigators try to investigate the efficacy of preservative free diquafosol ophthalmic solution compared to preservative containing diquafosol ophthalmic solution and sodium hyaluronate ophthalmic solution, which are widely used in patients with DE after cataract surgery.
The objective of this study is to evaluate the safety and effectiveness of OC-01 Nasal Spray as compared to placebo on signs and symptoms of dry eye disease
The objective of this study is to evaluate the safety and effectiveness of OC-02 nasal spray compared to placebo on signs and symptoms of dry eye disease (DED).
Traditionally, Manuka honey has been used to combat against bacteria and reduce inflammation (the body's way of reacting to infection, irritation or other injury). Due to the inflammatory nature of dry eye, Manuka eye drops show promise as a treatment for dry eye disease. The aim of this research is to compare the effects of two over the counter eye drops that are used to treat dry eye conditions over a one month period.
A total of 50 eyes were analyzed (25 patients). The subjects selected were over 18 years of age. No gender distinction was made in the choice of subjects. All subjects were carriers of silicone hydrogel contact lenses. The antecedents of the eye diseases not identified, neither the previous eye surgeries nor the systemic or ocular medication. All patients read, understood and signed an informed consent form of the study.
The primary purpose of this study is to determine the efficacy and safety of KPI-121 0.25% ophthalmic suspension compared to vehicle (placebo) in subjects who have a documented clinical diagnosis of dry eye disease. The product will be studied over 14 days, with 1-2 drops instilled in each eye four times daily (QID).
Two-period, controlled, randomized and open clinical trial. The sample was composed of adult women with moderate to severe hypo secretory dry eye associated with Sjögren's syndrome, who attended the ocular surface office, derived from the general ophthalmology clinic, from the Rheumatology or Immunology department. The three interventions were randomized: autologous serum (GSA), Rebamipida 2% (GR) and a combined treatment (GSAR). The following were used as outcome measures: OSDI self-administered questionnaire (Ocular Surface Disease Index), tear-rupture time (BUT), fluorescein staining, Bengal Rose staining and Schirmer's test without anesthesia to assess the answer to each treatment
Protocol AXR201701 is a multicenter, double-masked, vehicle-controlled, randomized, parallel group study carried out in 2 stages (Stage 1: AXR-159 Ophthalmic Solution (30 mg/mL or 50 mg/mL); Stage 2: AXR-159 Ophthalmic Solution (3 mg/mL, 30 mg/mL or 50 mg/mL) in approximately 430 patients diagnosed with dry eye disease (DED).
