Despite their wide availability on the European market, there is a lack of established classifications based on their physicochemical properties. The aim of our study was therefore (i) to develop an analytical method that measures the concentration and the molecular weight (MW) of the hyaluronic acid (HA) in commercialized products, and (ii) to propose an overview based on their various physicochemical parameters.</p><p><strong>Methods: </strong>The intrinsic viscosity and MW of the HA, as well as osmolarity, pH, rheological profile, and viscosity, were measured or determined. A specific method was developed to measure the average intrinsic viscosity and HA content using a liquid size-exclusion chromatography system. The MW was determined using the Mark-Houwink equation.</p><p><strong>Results: </strong>Thirty-seven products commercialized in Europe were analyzed, with 21 of them containing HA. The HA MW was lowest (300 kDa) for Thealose^®, Thealoz Duo^® Gel, and Hyabak^®, and highest (1300 kDa) for Vismed^® Multi, Vismed^® Gel, and Neovis^® Gel. The pH values varied between 5.94 for Treovis^® and 8.06 for Systane^® Ultra. Osmolarity ranged between 148 mOsm/L and 325 mOsm/L for Neovis^® and Treovis^®, respectively. Viscosity was highly variable, ranging from 0.38 mPas·s for Hylolipid^® to 337.47 mPas·s for Thealoz^® Duo Gel. Finally, rheological profile analysis revealed different shear-thinning behaviors.</p><p><strong>Conclusion: </strong>While the perfect eye drop does not exist, a multitude of options are available to choose from.

Among them, 53.2% were married, while 43.1% lived alone.</p><h3 data-test=\"abstract-sub-heading\">Conclusions</h3><p>Data from the I-OPTA (Identification of Patient-Reported Barriers in Treatment for nAMD) questionnaire allows future exploration of patients who are no longer receiving treatment, patients’ knowledge about preventive measures, and the impact of nAMD on visual function and quality of life. Future research, including studies that integrate data from corresponding retinal images and Danish national registers, has the potential to generate invaluable knowledge, providing benefits to both patients and healthcare professionals.</p>","PeriodicalId":19623,"journal":{"name":"Ophthalmology and Therapy","volume":"215 1","pages":""},"PeriodicalIF":3.3,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142260032","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
