Summary
Delayed sequential bilateral cataract surgery (DSBCS) in Sweden decreased over a decade. Most DSBCS occurred within 3 months, influenced by factors like IOL type and patient age.
Area of Science:
- Ophthalmology
- Public Health
- Health Services Research
Background:
- Delayed sequential bilateral cataract surgery (DSBCS) involves operating on both eyes on different days.
- Understanding trends in DSBCS is crucial for optimizing patient care and resource allocation.
Purpose of the Study:
- To analyze the trends and influencing factors of DSBCS in Sweden from 2010 to 2019.
Main Methods:
- A register-based cohort study using the Swedish National Cataract Register (NCR) from 2010-2019.
- Linked patient data for 368,106 DSBCS cases, analyzing associations with various clinical and demographic factors using logistic regression.
Main Results:
- 62.6% of DSBCS cases were performed within 3 months, with a decreasing interval over time.
- Factors like recent surgery year, private clinics, older age, and multifocal IOLs were linked to shorter intervals.
- Longer intervals were associated with better fellow eye visual acuity, ocular comorbidities, and perioperative complications.
Conclusions:
- The interval between sequential bilateral cataract surgeries is decreasing in Sweden.
- Clinical practice should consider the patient's overall visual function to determine optimal timing for the second eye surgery.
