Conclusion
The economic evaluation alongside RCT demonstrated that outpatient-balloon IOL was more likely to be cost-effective compared to inpatient-PG IOL and could be cost-saving. For nulliparous women (outpatient-balloon IOL) and for parous women (inpatient-PG IOL), the uncertainty surrounding cost-effectiveness is reduced. These findings were reported from a health services perspective and will aid decision-makers to allocate scarce resources efficiently.
