Comparison of Ocular Lubricants in People With Symptoms of Dry Eye

Ocular dryness and discomfort are symptoms commonly associated with dry eye. Lubricating eye drops, also called artificial tears, are often used to moisten the eye and provide relief from these symptoms. There are currently several types of lubricating eye drops available, differing in their ingredients, consistency, and recommended frequency of application. The aim of this study is to compare the effectiveness of two lubricating eye drops that differ in their ingredients and recommended frequency of application. The goal is to see whether they perform the same or if one of them provides better relief for people with dry eye symptoms. One of the eye drops is commercially available in Canada, the other one is not commercially available in Canada and therefore considered an investigational eye drop. This eye drop is available in the United States of America. In this study, participants will use one drop twice per day and the other drop four times per day. Each product will be used for 4 weeks and all participants will use both products (one after the other). There will be a 2-week period of no drops between the two study products. Before starting each drop and after 4 weeks of drop use, we will assess the eyes of the participants and ask them how their eyes feel. Participants will also be asked to answer a series of questions regarding the drops. Participants will encounter procedures that they normally experience in an eye care setting. The results will help the funding company to better understand the performance of the products used in this study. It may also help eyecare practitioners in managing their patients with dry eye symptoms. The hypothesis is that the drop used twice a day will be non-inferior to the drop used 4 times per day for the change in dry eye symptoms (assessed with the Ocular Surface Disease Index questionnaire) after 4 weeks of use.

Safety and Efficacy of Kelulut Honey Eyedrops in Dry Eye Disease

The goal of this clinical trial is to learn whether Kelulut honey eyedrops are safe and helpful in treating dry eye disease in adults. It will also learn about any side effects that may occur with the use of Kelulut honey eyedrops. This Kelulut honey eyedrops are sterile ophthalmic solutions formulated with honey derived from stingless bees (Trigona spp.) at concentrations of 12.5% 25% and 50%. The eyedrop formulations are prepared according to a standardized laboratory protocol to ensure sterility, stability, and suitability for ocular use. Full formulation details are proprietary but can be provided to the ethics committee or regulatory authorities upon request. The main questions this clinical trial aims to answer are: 1. Does Kelulut honey improve tear film stability and dry eye symptoms? 2. Are Kelulut honey eyedrops safe and well tolerated on the ocular surface? Researchers will compare different concentrations of Kelulut honey eyedrops to determine which concentration provides the best balance of safety and clinical benefit. Participants will: 1. Use Kelulut honey eyedrops (12.5%, 25%, or 50%) three times daily for 1 month, in addition to continuing their usual dry eye treatments. 2. Attend scheduled follow-up visits (on week 2 and week 4) for eye examinations and dry eye assessments (e.g., TBUT, ocular surface staining, Schirmer test, and OSDI). 3. Report any changes in symptoms or any discomfort, including stinging, redness, irritation, or other adverse effects experienced during the study.

Kelulut Honey for Allergic Conjunctivitis and Dry Eye Symptoms

The goal of this clinical trial is to learn if oral Kelulut honey works to improve eye symptoms in adults with allergic conjunctivitis. It will also look at how safe Kelulut honey is when taken as a daily supplement. The main questions it aims to answer are: 1. Does oral Kelulut honey reduce itchy, red, watery eyes and dry eye symptoms in people with allergic conjunctivitis? 2. Does oral Kelulut honey improve tear film stability and the health of conjunctival goblet cells (special cells on the eye surface that help keep the eye moist)? 3. What side effects or medical problems do participants have when taking Kelulut honey? Researchers will compare oral Kelulut honey to a honey-flavoured placebo syrup (a look-alike drink that does not contain Kelulut honey) to see if Kelulut honey is more effective than placebo for treating eye symptoms in allergic conjunctivitis. Participants will: 1. Take either oral Kelulut honey or a honey-flavoured placebo syrup every day for 1 month 2. Continue their usual treatment for allergic conjunctivitis and dry eye disease as prescribed by their eye doctor 3. Attend clinic visits for eye check-ups, including tests of tear film stability, dry eye symptoms, and eye surface health 4. Answer questionnaires about their eye symptoms and how these affect their daily activities and vision-related quality of life Participation is voluntary, and participants may stop taking part in the study at any time. Data collected up to the time they withdraw may still be used for research, but their routine medical care will not be affected
