Filter by:The main aim of this investigation is to evaluate the effect of the preservative-free ophthalmic solution IRIDIUM® A gel on the ocular surface of patients with glaucoma or OHT and concomitant DES under multiple long-term topical hypotensive therapy for at least 6 months. The underlying assumption is that ophthalmic solutions as adjuvants for the management of IOP- or glaucoma-associated dry eye may induce a protection of the eye surface with consequent improvement of the symptoms and of the overall quality of life.
This is a profit, multicentric, prospective, open-label, non-pharmacological clinical investigation aim to evaluate the efficacy and tollerability of two types of eye drops containing Hyaluronic acid (HA) with different concentration as 0.30% (BLUgel A) and 0.15% (BLUyal A). the study will consider patients affected by moderate to severe dry eye syndrome which will be treated with HA 0.30% while patients affected by mild dry eye syndrome will be treated with HA 0.15%.Dry eye syndrome (DES) is defined as a multifactorial disease of the ocular surface that results in symptoms of discomfort, visual disturbance, and tear film instability with potential damage to the ocular surface.Based on the available background on the use of HA in the management of DES, this investigation has been designed to assess the efficacy of HA- and amino acid-based product BLUgel A free and BLUyal A free, in patients with moderate to severe and mild dry eye syndrome, respectively.
This is a prospective cohort study to compare subjective changes in symptoms using the Ocular Surface Disease Index (OSDI) questionnaire, following the recommended dosage of the new nanoemulsion eye drops (Systane Complete)in mild to moderate dry eye patients, and to investigate objective ocular surface changes using modern clinical instruments during the study period.
A Phase 3 Multi-Center, Randomized, Double Masked, Vehicle Controlled Study to Assess the Safety and Efficacy of ST-100 (vezocolmitide) Ophthalmic Solution 60 μg/ml Ophthalmic Solution in Subjects Diagnosed with Dry Eye Disease (DED)
Age-related macular degeneration (AMD) is the 1st cause of visual impairment after the age of 50. Its most aggressive form, wet AMD, requires regular intravitreal injections (IVI) spaced 4 to 8 weeks apart usually depending on the treatment regimen and the patient's response. The IVI procedure requires a double disinfection with periocular and conjunctival cutaneous povidone-iodine. Antiseptic agents such as povidone iodine are a highly likely factor in the development of dry eye syndrome. Clinical data have demonstrated the abrasive and toxic effects of their use on the ocular surface, especially with repeated exposure (Saedon H, Nosek J, Phillips J. Ocular surface effects of repeated application of povisoden-iodine in patients receiving frequent intravitreal injections. Cutaneous and Ocular Toxicology. 2017;36(4):343-6.). The IVIS study coordinated by Prof. Dot reported impaired ocular surface and quality of life immediately after IVI. The authors suggest 3 levels of action to improve immediate tolerance: (i) improve the basal status of the ocular surface, (ii) reduce the contact time with povidone-iodine which could be toxic to the ocular surface and (iii) improve immediate post-IVI treatment. (Verrecchia S et al. A prospective multicentre study of intravitreal injections and ocular surface in 219 patients: IVIS study. Acta Ophthalmol. 2021 Mar 18). This study is part of the extension of the IVIS study. IVIs are effective and do not currently present a therapeutic alternative. However, their role in the development or exacerbation of dry eye is still poorly evaluated although millions of IVIs are performed each year worldwide (1.3 million in France in 2019). In addition, discomfort after injection is one of the factors that limit adherence to long-term IVI treatment, some patients fearing this repeated act. We propose in this bicentric, prospective, randomized, parallel group study, to evaluate in this context the impact of the continuous consideration of the risk of dry eye. The expected results are the objective improvement of dry eye indicators, comfort and quality of life of patients, all aimed at optimizing the adherence of our patients to their AMD treatment.
This study is to verify the efficacy and safety in the treatment of dry eye syndrome in patients prescribed with Diquasol eye drops as a monotherapy, or in combination with Hyaluron eye drops, or in combination with Hyaluronmax eye drops.
Observational and prospective cohort study that seek to evaluate the epidemiological characteristics and changes in the ocular surface of patients diagnosed with dry eye disease who are treated with preservative-free lubricating drops.
The goal of this clinical trial is to determine the effectiveness of preventive therapy with diquafosol sodium 3% compared to sodium hyaluronate 0.1% to prevent dry eye disease in patient who will undergo cataract surgery. The main questions it aims to answer are: - The percentage reduction in subjective symptoms and signs of dry eye disease after cataract surgery. - The differences in the use of diquafosol sodium 3% and sodium hyaluronate 0.1% in improving dry eye disease signs in patients objectively. - The tear osmolarity and matix metalloproteinase-9 (MMP-9) after the treatment. - The difference in visual quality improvement assessed from higher order aberrations (HOA) and contrast sensitivity after administration of diquafosol sodium 3% compared to sodium hyaluronate 0.1%. Participants will receive diquafosol sodium 3% or sodium hyaluronate 0.1% for 4 weeks before the cataract surgery and 21 days after the surgery, and will be: - Interviewed regarding their identity, history of illness, and symptoms of dry eye disease. - Examined by researchers: eye condition, contrast sensitivity using the Pelli-Robson diagram, keratograph, HOA, tear osmolarity, MMP-9, corneal sensitivity, tear break up time (TBUT) , fluorescein break up pattern (FBUP). This examination will be carried out 4 times: on the first day before the research series, four weeks after giving therapy before cataract surgery, 21 days after cataract surgery, and 90 days after cataract surgery.
This study aims to evaluate the efficacy and safety of applying pulse Electrical Stimulation around eye after laser keratoplasty (LASEK) in patients with dry eye syndrome.
