Detection and Optimization of Treatment of Severe Cases of Dry Eye Disease

The bulk of dry eye patients are found in the community. The lack of satisfactory protocols and confidence is a significant deterrent for practitioners to manage such patients, which may result in inaccurate referrals, and unhappy patients. Problems are compounded by comorbidities of dry eye, even if these are not diagnosed formally. Aligning with the healthcare strategy to move beyond healthcare to health, and beyond hospital care to community care, investigators propose that the confidence of primary carers be increased by using an image-based screening system. This study aim to determine the efficacy of this screening AI algorithm, a prototype, in addition to or instead of screening of dry eye using a simple DEQ-5 symptom questionnaire.

Study of Blinking as a Function of Tear Film Quality

The goal of this study is to better understand how eye blinking behavior is linked to the stability of the tear film, in adults aged 18 to 65 years, with or without symptoms of dry eye. The main questions are: * Do the results of a New Blink Task reflect tear film stability ? * How are the blink related metrics in relation with each other? Researchers will compare two groups of participants-those without dry eye symptoms and those with dry eye symptoms-to see if blinking measures differ between them and whether these measures relate differently to tear film quality. Participants will: * Answer a questionnaire about dry eye symptoms * Have their visual correction measured (if they wear glasses) * Undergo non-invasive assessments of tear film quality using an imaging device * Complete three types of blink tasks, each repeated three times, including measurements of blinking and of tear film stability

Telemedicine for Evaluating Dry Eye Disease (DED) Using a Mobile Phone-Attached Portable Automatic Ocular Surface Imaging Device (PAOSID): A Patient-Operated Diagnostic and Continuous Ocular Surface Monitoring (COSM) System

Dry eye disease (DED) is a common eye condition that is becoming more widespread. Detecting it early, keeping track of its progression, and following up regularly can help protect vision and prevent serious complications. However, due to a shortage of ophthalmologists, limited access to eye care services, and disparities in care quality, many patients receive infrequent or insufficient clinical consultations. To address these needs, a portable automatic ocular surface imaging device (PAOSID) that attaches to a mobile phone has been developed. This device uses three types of light including white, infrared, and cobalt blue light to capture clear images and videos of the eye's surface. It also has a smart system that automatically takes high-quality images, allowing patients to use it at home independently. This device may help detect early signs of DED and monitor eye health more easily.

Comparing Tear Proteomics Profile in Dry Eye Disease pre-and Post-treatment With Low Level Light Therapy

The purpose of this research study is to understand the mechanism of action of low level light therapy and also potentially yield markers associated with good treatment response. Low-level light therapy is light-based treatment delivered through advance eye-light device. This therapy uses light energy to provide energy to the meibomian gland cells to slow down age-ing, improve tear stability and reduce inflammation.

SAS 1: Develop Ocular Disease (OSD) Diagnostic, Algorithms, and Management Protocols for Cataract Surgery

Patient: Tear film issues resulting in poor visual outcomes are a major cause of dissatisfaction after cataract surgery. There is no universal best preoperative algorithm for managing the ocular surface prior to surgery. Industry: Recent advances in tear/cornea imaging and refractive cataract surgery such as multifocal intraocular lenses will be advantageous to patients only if tear film issues can be addressed. Society: Cataract surgery is the most common ophthalmic surgery done in Singapore and worldwide. Improving vision by attending to tear film problems improves quality of life.

Eyelid Closure in Keratometry

Cataract surgery is one of the most common performed surgeries in the world. While in the early beginnings of cataract surgery, visual rehabilitation was the main goal of the procedure, refractive outcome and subsequent relative spectacles independency is gaining increasing importance in patients' demands. Due to the improvements in measurement techniques and prediction formulas, the prediction of postoperative refraction is possible with high accuracy. However, there are still some sources of error that lead to deviations of predicted postoperative refraction. For instance, it was shown that tear film osmolarity, an established biomarker for dry eye disease (DED), plays an important role in preoperative precision of keratometry measurements. Keratometry, the measurement of corneal curvature, is an important part of preoperative biometry. Errors in preoperative keratometry measurements lead to nearly one-to-one deviations from the predicted refraction. Therefore, proper keratometry measurements are a key element in intraocular lens (IOL) power calculations. To counteract the issue of DED in preoperative biometry, the principle of using lubricating eye drops before ocular biometry has been investigated and it was shown that the use of ocular lubricants may lead to increased variability of keratometry measurements. From our clinical observations, another possible mechanism to improve keratometry is eyelid closure for some minutes. In contrast to the long-term use of ocular lubricants to stabilize the tear film, eyelid closure is an easy and fast intervention to possibly improve the precision of keratometry measurements. Additionally, a clinical trial investigating the usage of lubricating eye drops for two weeks found no improvement of variability of keratometry in DED patients. Therefore, this study aims to investigate the effect of eyelid closure on the quality index of keratometric measurements in patients with a warning for the quality of keratometric measurements. For this purpose, a single study day including 4 repeated measurements (2 without and 2 with lid closure for 3 minutes) using an ocular biometer (IOLMaster700) will be performed.
