Cataract Surgery Real-World Data

Cataract surgery is the most effective treatment for cataracts, with about 3 million procedures performed annually in the United States. Qdata® Cataracts can help reveal insights into this patient population, clinical outcomes, and treatment effectiveness.

Qdata Cataracts is a unique real-world dataset that enables precise analysis of patients undergoing cataract surgery while also tracking their outcomes through unstructured clinical notes of electronic health records (EHRs).

About Qdata Cataracts

Unlocking Insights into Cataract Surgery and Outcomes

Cataracts affect millions of people worldwide, clouding vision and impacting quality of life. The condition occurs when the eye’s natural lens becomes clouded, impairing vision. Cataracts develop gradually, leading to symptoms such as blurred vision, difficulty seeing at night, glare sensitivity, and faded colors. If left untreated, cataracts can cause severe vision loss.

The most effective treatment is cataract surgery in which the cloudy lens is removed and replaced with a synthetic intraocular lens (IOL), restoring clear vision. However, variations in surgical techniques, IOL models, and patient characteristics can impact outcomes, making real-world data essential for understanding long-term effectiveness and optimizing patient care.

Verana Health’s Qdata Cataracts, a research-ready, fit-for-purpose real-world data module,  offers life sciences companies real-world insights into patient demographics, clinical outcomes, and treatment effectiveness on 9M+ cataract surgery patients. Key patient outcomes, including visual acuity (VA), IOP readings, intraocular lens (IOL) brands/models, and femtosecond laser assisted cataract surgery (FLACS)*, are extracted from unstructured and semi-structured fields in EHRs, which Verana Health has access to through an exclusive data partnership with the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight). The IRIS Registry is the world’s largest specialty society clinical data registry in all of medicine and the first comprehensive eye disease clinical registry in the U.S.

Key Variables for Cataract Surgery Research

Qdata Cataracts enables precise analysis of patient characteristics and outcomes, providing valuable insights for life sciences research, including:

Visual Acuity

Measures how sharp your vision is at a distance; usually tested by reading an eye chart, and is an outcome measure from EHR semi-structured fields.

Intraocular Pressure (IOP) Reading

Measures the fluid pressure inside your eye during an eye exam. A high IOP reading could indicate a risk of glaucoma.

Intraocular Lens (IOL) Brand/Model

IOLs are an artificial lens that is implanted in the eye during cataract surgery to replace the natural lens that has become cloudy.

Femtosecond laser assisted cataract surgery (FLACS)*

A minimally invasive eye surgery that uses a laser to perform precise incisions and lens fragmentation. FLACS is a modern alternative to traditional cataract surgery.

Unstructured Data Enables Deeper Understanding

Artificial intelligence-powered techniques, such as machine learning and natural language processing, can extract key terms and phrases from unstructured ophthalmology EHR clinical notes and semi-structured fields to identify key outcomes of cataract surgery patients.
