Analyzing ocular surface biomarkers for cataract surgery

Metabo-lipidomic Analysis of the Ocular Surface and Aqueous Humor for the Search of Predictive Biomarkers of Ocular Surface Disease After Cataract Surgery: a Prospective Cohort Study

Not applicable Interventional University Hospital, Tours · NCT05802550

This study is testing if certain eye surface markers can help predict the risk of problems after cataract surgery to improve recovery and quality of life for patients.

What this trial studies

This study investigates the ocular surface of patients undergoing cataract surgery to identify biomarkers that may predict the risk of postoperative ocular surface disease. By utilizing conjunctival impression cytology and collecting aqueous humor, researchers aim to develop a better understanding of how these factors influence visual recovery and quality of life after surgery. The goal is to personalize perioperative care based on the identified biomarkers, potentially improving outcomes for patients. This approach combines advanced metabolomic techniques with clinical assessments to enhance patient care.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 50 and older with cortico-nuclear and/or subcapsular age-related cataracts.

Not a fit: Patients with a history of recent ocular surgery, other types of cataracts, or conditions affecting the ocular surface may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved personalized care for cataract surgery patients, reducing the risk of postoperative ocular surface disease.

How similar studies have performed: While the specific approach of this study may be novel, similar studies have shown promise in identifying ocular surface biomarkers in other contexts.
