Cataract surgery. Outcome assessments and epidemiologic aspects

Area of Science:

• Ophthalmology and Vision Science
• Public Health and Healthcare Management

Background:

• Limited knowledge exists regarding cataract surgery outcomes, pre-operative prediction, and epidemiological aspects.
• Accurate data is crucial for improving cataract treatment and allocating healthcare resources effectively.

Purpose of the Study:

• To assess the effectiveness of cataract surgery through outcome studies.
• To evaluate a new visual functioning index as a tool for rehabilitation assessment.
• To analyze predictors of outcomes and patient satisfaction.

Main Methods:

• Review of 12 studies focusing on cataract surgery effectiveness, pre-operative prediction, and epidemiology.
• Development and evaluation of a visual functioning index.
• Assessment of visual acuity, rehabilitation problems, and patient satisfaction in various patient groups (spectacle-corrected, intraocular lens, contact lens).

Main Results:

• 82% of patients achieved visual acuity of 0.5 or better; 74% had near-normal basic visual functioning post-surgery (without intraocular lenses).
• Significant challenges in adapting to aphakic spectacles were noted, leading to dissatisfaction in 26% of patients.
• Intraocular lenses and contact lenses resulted in better visual functioning and higher patient satisfaction compared to spectacle correction, especially for monaphakic patients.

Conclusions:

• While cataract surgery improves basic vision, challenges with aphakic spectacles impact overall patient satisfaction.
• Second eye surgery appears to enhance delicate visual functioning and subjective visual comfort.
• Advanced correction methods like intraocular lenses and contact lenses offer superior outcomes and satisfaction over traditional spectacles.
