The National Cataract Surgery Survey: I. Method and descriptive features

Area of Science:

• Ophthalmology
• Public Health
• Health Services Research

Background:

• Age-related cataract is a leading cause of visual impairment globally.
• Understanding patient characteristics and surgical processes is crucial for optimizing cataract surgery services.
• The National Health Service (NHS) in the UK provides a large population base for such studies.

Purpose of the Study:

• To establish a baseline profile of patients undergoing cataract surgery in the UK.
• To describe the characteristics of patients admitted for age-related cataract surgery.
• To detail the surgical procedures performed in 1990, including cataract extraction and intraocular lens implantation.

Main Methods:

• Prospective, cross-sectional survey design.
• Data collection on patient demographics, referral sources, ocular comorbidities, visual impairment, and waiting times.
• Analysis of surgical procedure details: number of operations, admission type, anesthesia, extraction method, intraocular lens use, and surgeon grade.

Main Results:

• Provides a demographic profile of patients seeking cataract surgery.
• Details the extent of visual impairment and waiting times for surgical intervention.
• Characterizes the surgical process in 1990, including common procedures and materials used.

Conclusions:

• Establishes the first national clinical dataset for UK cataract surgery.
• Offers insights into patient populations and surgical practices for age-related cataracts.
• Serves as a foundational study for future research and service improvement in cataract care.
