Filter by:The purpose of the study is to compare the efficacy and safety of 5% tavilermide ophthalmic solution to placebo for the treatment of the signs and symptoms of dry eye disease.
The purpose of this interventional study is to assess safety, patient tolerability, plug retention rate, and preliminary efficacy in improving the symptoms of Dry Eye Disease (DED) of EXP-TC tacrolimus releasing punctal plug. The main questions it aims to answer are: 1. The safety of using EXP-TC plug following all study adverse events 2. The number of patients with Adverse Events related to the us of EXP-LP plug 3. The number of patients discontinuing the study due to plug discomfort 4. The total patients with plugs remained during the 3-months study duration from plug insertion 5. Exploratory: change from baseline in the study eye to follow-up visits in various Dryness clinical measurements. The change of measurements from baseline will also be compared between the study and fellow control eye (receiving artificial tears only, 0.15% sodium hyaluronate).
Adenoviral keratitis(caused by adenovirus) is one of the most frequently diagnosed eye diseases. Most of these infections have symptoms like (Ocular itchiness and irritation, chemosis (conjunctival edema),photophobia, epiphora, foreign body sensation, epithelial keratitis etc.Adenoviral subepithelial infiltration is one of the most difficult complication to treat. Our purpose is to evaluate corneal transparency, recurrence, and visual acuity in patients with adenoviral subepithelial infiltration by first removing the infiltrative stroma with a smile and implanting the same volume of fresh lenticule in the prepared stromal pocket.
The specific aims of the the investigators studies are as follows: - To collect the tear samples from patients with different ocular surface disorders, including SLK, conjunctivochalasis, and keratoconjunctivitis sicca (KCS). - To evaluate the differential expression of tear cytokines and pH values between different ocular surface disorders. - To collect the surgical conjunctival specimens from the patients with SLK and conjunctivochalasis. - To evaluate the factors inducing mast cell migration and how mast cell is activated in SLK via surgical specimens and cultivated fibroblast.
Purpose: To develop a screening metric by examining both the characteristics of the preoperative tear film and the intracellular signaling pathways of conjunctival goblet cells in order to determine if there are certain characteristics which might predict those patients who will experience serious dry eye symptoms and complications after refractive surgery. Research Design: This study is a twelve-month prospective non-randomized investigation. Methodology: In conjunction with psychometric questionnaires and various measures of tear film quality (e.g. Schirmer's test, tear break up time, etc), impression cytology will be used to assess the intracellular signaling pathways of conjunctival goblet cells and to determine if alterations in this pathway exist. Alterations in this pathway would result in a reduced response by the mucin secreting conjunctival goblet cells thereby promoting the development of dry eye after refractive surgery.
