# 4-Minute Phaco™ vs. conventional phaco

[4-Minute Phaco™](https://bluefinvision.com/4-minute-phaco/) and conventional phacoemulsification both use ultrasound energy to break down and remove the cataract. The difference lies in workflow efficiency, chamber stability, and the consistency achieved through high-volume surgical experience.

## Key Differences

Conventional cataract surgery typically takes 10 to 20 minutes, depending on cataract density and surgeon experience. 4-Minute Phaco™ achieves the same clinical result in a shorter timeframe through:

- Standardised surgical steps with minimal variation
- Advanced fluidics maintaining stable anterior chamber pressure
- Reduced instrument exchanges and intraocular manipulation

These factors lower the cumulative stress placed on the eye during surgery.

## Impact on the Cornea

The corneal endothelium does not regenerate. Prolonged ultrasound exposure and fluid turbulence can damage these cells, potentially affecting long-term corneal clarity. 4-Minute Phaco™ reduces both exposure time and energy delivery, supporting better endothelial preservation.

## Outcomes and Recovery

Patients undergoing 4-Minute Phaco™ often experience faster visual recovery and lower rates of post-operative inflammation. The reproducibility of the technique also supports more predictable refractive outcomes, particularly important when premium lenses are used.
