Hypothesis
What is the proportion and time-trend of second-eye cataract surgery in Catalonia, and how does it vary by gender, age, and region?
Conclusion
The study predicts greater utilization of second-eye surgery in patients aged 70 to 79 years and in women, with a substantial unmet need for bilateral surgery.
Supporting Evidence
- The proportion of second-eye surgery was 30.0% and showed an increasing trend.
- Women had a 1.9% higher proportion of second-eye surgery compared to men.
- Patients aged 70 to 79 had the highest proportion of second-eye surgeries.
Takeaway
The study looked at how many people got surgery on both eyes for cataracts and found that more women and older people are getting this surgery over time.
Methodology
Data from the Minimum Data Set of Catalonia was analyzed for cataract surgeries performed between 1999 and 2002, focusing on second-eye surgeries.
Potential Biases
Potential bias in identifying first- and second-eye surgeries due to registry errors.
Limitations
The study could not identify patients undergoing surgeries in different hospitals, which may lead to underestimation of second-eye surgeries.
Participant Demographics
Patients included were from the public health system in Catalonia, with a mean age of 74.4 years at first-eye surgery.
