Active clinical trials for "Dry Eye Syndromes"

Rationale: Serum eye drops (SEDs) are used to treat patients with severe signs and symptoms of dry eyes and other corneal defects. Serum is used in severe ophthalmic cases where conventional treatment and/or eye drops (artificial tears) have insufficient effect. The use of SEDs in dry eye patients usually has a rapid effect. Most patients claim the effect to be instantaneous, and most symptoms improve within 48-72 hours. There is evidence suggesting that substances in serum may help in the healing of epithelial defects, such as epidermal growth factor, fibroblast growth factor, fibronectin, and/or vitamin A. However, the precise serum factor responsible for alleviating the patient's complaints is currently not known. SEDs are considered as a blood product under EU blood legislation (Directive 2002/98/EC), as well as in New Zealand and Australia. Commonly, autologous SEDs are used, but they are replaced more and more by allogeneic SEDs prepared from donor serum. Allogeneic SEDs are derived from healthy voluntary, non-remunerated male donors with blood group AB, and have the benefit of blood bank controlled quality. They can be delivered from stock and are therefore quickly available for each patient. For application of eye drops, generally administration systems with a drop size of 40 to 50 µl are used, further on referred to as conventional sized eye drops. From previous studies done with medicinal eye drops, it has been shown that smaller eye drops, so called micro drops, can be just as effective and sometimes even superior to conventional drops for treatment of eye disease. If micro drops are just as effective or maybe even superior to conventional sized eye drops is currently unknown for the use of SEDs. This study will compare the feasibility and effectiveness of allogeneic serum micro eye drops using the mu-Drop applicator to the conventional sized allogeneic eye drops using the Meise applicator. Both systems have a closed manufacturing system. Objective: The main objective is to determine whether the administration of allogeneic serum micro eye drops is non-inferior in terms of effectiveness and safety as compared to the conventional sized drops. Main study parameters/endpoints: The primary endpoint is the improvement in OSDI score by using SEDs (OSDI score after treatment minus OSDI score before treatment), independent of the drop size, showing non-inferiority for the use of micro drops as compared to conventional sized drops.

This study is being conducted to evaluate the short-term (1 month) safety and effectiveness of a single TearCare procedure to treat adult patients with dry eye disease. NOTE: All sites have been selected for this study.

The purpose of this study is to evaluate the clinical utility, safety, and effectiveness of the TearCare™ System compared to standardized warm compress therapy for the application of controlled, localized heat therapy in adult patients with dry eye syndrome.

The proposed 3-month study is a prospective, open-label, multicentre, phase IV, proof of concept study. The study is designed to assess the effect on the quality of vision of IKERVIS® (1mg/mL ciclosporin) eye drops administered once daily in dry eye disease (DED) patients with severe keratitis, as well as its safety and efficacy.

The purpose of this study is to compare the effects of autologous serum 20% and autologous serum 50% for the treatment of Severe Dry Eye Syndrome

A multicenter randomized controlled trial on prevention and treatment of ocular surface injury and meibomian gland dysfunction in patients using anti-glaucoma eye drops.

In this study, the TearCare System will be compared with the LipiFlow Thermal Pulsation System in patients with dry eye disease. The objective is to demonstrate that the TearCare System is safe and effective in relieving the signs and symptoms of dry eye disease. NOTE: All sites have been selected for this study. We are not seeking additional sites at this time.

The purpose of this study is to compare the efficacy and safety of CKD-350 in patients with dry eye syndrome

A clinical trial to evaluate the efficacy and safety of Cyclosporine 0.1% (Ikervis®) for moderate to severe dry eye patients who changed to Cyclosporine 0.1% eye drop(Ikervis®) due to lack of treatment effects of the previous Cyclosporine 0.05% eye drop.

To study the efficacy of an ocular bandage contact lens for the treatment of dry eye after complicated and combined cataract surgery
