Comparison of Tear Evaporation Rate With DAILIES TOTAL1 and Biotrue ONEday
Evaporative Dry EyeThe purpose of this pilot study is to compare the effect of DAILIES TOTAL1, a low water content silicone hydrogel lens, and Biotrue ONEday, a high water content hydrogel lens, on the rate of tear evaporation. The study will also serve to validate the novel, in-house developed evaporimeter.
Short and Long-term Results of Skin Versus Skin Plus Orbicularis Resection Blepharoplasty
Dermatochalasis of EyelidOcular Surface Disease3 moreThis study aims to evaluate the short and long-term effects of skin-only and skin+muscle excision blepharoplasty on corneal nerves, dry eye parameters, meibomian glands, and eyebrow position.
Effect of ADDE on Tear Interferometry
TearDry Eye SyndromesImportance: Lipid layer thickness (LLT) reflects the lipid components of tear film, but is affected by the mucocutaneous components. This study investigated the therapeutic effect of the treatments for aqueous-deficient dry eye (ADDE) on LLT. Objective: To investigate the effect of ADDE and its treatments on LLT measurements by tear interferometry. Design, Setting, and Participants: This prospective comparative interventional study included 152 eyes from 152 patients with ADDE. Interventions: Participants were classified into four groups: control group (Group 1), 3% diquafosol group (Group 2), punctal plug insertion group (Group 3), and combined treatment group (Group 4). Main Outcomes and Measures: Average LLT (LLTave) was measured using a LipiView® II tear interferometer at baseline and one month after treatments.
Concentration of Ofloxacin Into the Aqueous Humour of Patients With Dry Eye Disease
Dry Eye DiseaseAfter topical installation of one drop of 0.3% commercially available ofloxacin (Oxatrex®) four times at intervals of 15min in catarract patients with Dry Eye Disease, aqueous humour samples will be collected intraoperatively, one hour after the last installation. Concentration of ofloxacin in aqueous humour will be measured by HPLC-MS/MS.
Clinical Efficacy of Amniotic Membrane Extract Eye Drops in Dry Eye Treatment
Dry Eyes ChronicThis prospective longitudinal study aims at evaluating the clinical efficacy of human amniotic fluid extract eye drops in the treatment of dry eye disease. 25 patients who are diagnosed with dry eye disease as defined by our criteria will be recruited from the cornea and dry eye clinic at Stein Eye Institute, UCLA. Pre-treatment baseline evaluations, 6 weeks, 12 weeks, and 24 weeks post treatment assessments will be performed by the principle investigator and co-investigator. All tests are considered non-invasive and are within the standard of practice in the evaluation for dry eye disease: (1) Ocular Surface Disease Index Questionnaire (OSDI); (2) Non-contact Tear Break-up Time (NITBUT); (3) Shirmer's test without anesthesia; (4) Ocular Surface Staining with Fluorescein and Lissamine green. Result of each test will be compared and analyzed to provide evidence of treatment efficacy. Treatment will be initiated for 12 weeks at a self-administered dose of one drop in both eyes two times per day. A follow-up of the study will be observed at the 24th week from the first day of treatment. All side effects and adverse events will be carefully observed and documented. Patients will be able to discontinue using the medication if they are not tolerating any side effects.
Reproducibility of Tearfilm Osmolarity Measurements Using TearLab® in Patients With Dry Eye Syndrome...
Dry Eye SyndromeDry Eye Syndrome (DES) is a common condition that affects approximately 20% of adults aged 45 and older. Although several clinical tests for the diagnosis and monitoring of DES are available, currently no gold standard for the assessment of DES exists. It has, however, been hypothesized that the assessment of tear film osmolarity may be a new and promising approach of an objective and non-invasive method for diagnosis and monitoring of treatment success. Recently, a new commercially available instrument (TearLab®, OcuSens Inc, San Diego, USA) for the assessment of tear film osmolarity has been introduced. This instrument allows for the easy and non-invasive determination of tear film osmolarity. Unfortunately, no data about reproducibility are yet available. Consequently, the current study sets out to investigate the short time reproducibility of tear film osmolarity measurements using the TearLab® instrument.
Treatment of Ocular Graft-versus-Host Disease (GVHD) With Topical Loteprednol Etabonate 0.5%
Dry EyesThe purpose of this research is to: Evaluate the safety and efficacy of a steroid eye drop (Lotemax) in patients who have been diagnosed with graft-versus-host disease (GVHD), which is a complication that may occur after bone marrow transplant where the newly transplanted material attacks the patient's body and may cause eye dryness. Assess the safety and efficacy of Lotemax in decreasing the eye's reaction to the process in GVHD before the patient undergoes bone marrow transplant. Compare how well Lotemax works in decreasing the process in GVHD with an immunosuppressive eye drop (Restasis), which has been commonly used in the treatment of this condition.
Efficacy of Pulsed Light Therapy for Meibomian Gland Dysfunction and Dry Eye Syndrome
Meibomian Gland DysfunctionDry Eye SyndromeOur primary aim is to determine whether pulsed light therapy (PLT) is effective in reducing symptoms and improving clinical stigmata of dry eye syndrome (DES) associated with meibomian gland dysfunction (MGD) in patients with facial rosacea (which includes ocular rosacea). The uses of PLT are for treatment of rosacea, hair removal, pigmented lesions, and skin telangiectasias. The risks include the potential for transient sunburn-like sensations (i.e. redness, burning sensation) and particularly if not used properly, the potential to cause burns, blistering, scarring, and pigmentary changes.
The Effect of Cyclosporin Before Cataract Surgery
Dry Eye SyndromesTo evaluate the effect of cyclosporine eye drop before cataract surgery for the prevention of post cataract surgery dry eye syndrome.
Virgin Coconut Oil Contact Lens as Ocular Rewetting Agent
Dry EyesThis is a clinical trial where 44 subjects dry eyes were instilled with Virgin Coconut Oil (VCO CL) using contact lenses as its vehicle. All subjects are healthy subjects with no other ocular diseases except for having some dry eye symptoms (included with McMonnies questionnaires). Parameters measured at baseline and after 15 minutes of insertion and were compared. The control eyes were inserted with contact lenses soaked in saline (CCL). The eye that wears the VCO CL or the CCL were chosen randomly by masked operator. At the end of this study, the parameters measured will indicate if the VCO CL was able to retain tears in the eye and remove the dry eyes symptoms.
