Hypothesis
Torsional ultrasound combined with different parameter settings is more effective and safer for hard nucleus cataract extraction than conventional ultrasound.
Conclusion
Using torsional combined with ultrasound power or high fixed torsional amplitude results in better outcomes for hard nucleus cataract extraction compared to conventional methods.
Supporting Evidence
- The mean ultrasound time was significantly lower in the Fixed Torsional group compared to the Ultrasound group.
- The cumulative dissipated energy was also lower in the Torsional groups than in the Ultrasound group.
- Postoperative best corrected visual acuity was significantly better in the Torsional groups on days 1 and 7.
Takeaway
This study shows that a special type of ultrasound can help doctors remove cataracts more safely and effectively, leading to better vision after surgery.
Methodology
A prospective, randomized clinical study involving 198 patients with hard nucleus cataracts, comparing three surgical techniques.
Potential Biases
Potential bias from the single surgeon performing all surgeries and the masking of outcomes.
Limitations
Short-term follow-up and exclusion of patients with other eye conditions may limit generalizability.
Participant Demographics
198 patients, average age 69.3 years, 102 women and 96 men.
