Filter by:The purpose of this study is to explore the efficacy and safety of CsA ophthalmic gel in the treatment of moderate to severe tear deficiency dry eye with different dosage, frequency and concentration, and to preliminarily determine the optimal dosage, frequency and concentration, so as to provide a theoretical basis for the design of follow-up clinical studies.
The present study aimed to evaluate and compare the efficacy of a 1 month clinical trial of 50% AS for the treatment of severe dry eye syndrom (DES) based on Schirmer's Test, tear break-up time (TBUT), fluorescein staining, and ocular surface disease index (OSDI) scores, as compared to conventional preservative-free artificial tears (PFAT) plus 0.05% COE treatment in patients with severe DES
The objective of this exploratory study is to determine the safety and efficacy of 0.002% Naltrexone Ophthalmic Solution, compared to placebo for the treatment of the signs and symptoms of dry eye in diabetic subjects.
Upper eyelid treatment has not been used with previously described methods of treatment of dry eye disease using intense pulsed light therapy because the upper lids disease was typically not as advanced as lower lid and because direct treatment of the upper lid was not felt to be necessary as each light pulse extended over the entire periorbita even when concentrated on the lower lid.
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).
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).
