Routine preoperative medical testing for cataract surgery
Key result
Routine preoperative medical testing prior to cataract surgery did not reduce the risk of intraoperative (OR 1.02; 95% CI 0.85-1.22) or postoperative medical adverse events compared to no testing.

Main Result
Effect estimate: OR 1.02 (95% CI 0.85-1.22)
Routine preoperative medical testing does not increase the safety of cataract surgery and is associated with higher costs.
Limitations
- In developing country settings, medical history questionnaires would be useless to screen for risk since few people have ever been to a physician or diagnosed with chronic disease.

Keay et al. (2012) conducted a systematic review in Age-related cataract (n=21,531). Routine preoperative medical testing vs. Selective or no preoperative testing was evaluated on Intraoperative medical adverse events (OR 1.02, 95% CI 0.85-1.22). Routine preoperative medical testing prior to cataract surgery did not reduce the risk of intraoperative (OR 1.02; 95% CI 0.85-1.22) or postoperative medical adverse events compared to no testing.
