Summary

Bimanual microphacoemulsification used significantly less balanced salt solution (BSS) and reduced total surgical time compared to coaxial miniphacoemulsification in cataract surgery. Both methods proved safe and effective for patients.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Phacoemulsification is a standard cataract surgery technique.
  • Comparing different phacoemulsification methods is crucial for optimizing surgical outcomes.
  • Bimanual and coaxial techniques represent distinct approaches to emulsifying the cataractous lens.

Purpose of the Study:

  • To compare the clinical outcomes of bimanual microphacoemulsification versus coaxial miniphacoemulsification.
  • To evaluate the advantages of bimanual microphacoemulsification over the coaxial technique.

Main Methods:

  • A prospective clinical trial involving 100 eyes of 50 patients with grade 2-4 nuclear or corticonuclear cataracts.
  • Randomized assignment of 50 eyes to bimanual and 50 eyes to coaxial phacoemulsification.

Rotating the Intraocular Lens to Prevent Posterior Capsular Opacification in Cataract Surgeries

Published on: July 7, 2023

  • Standardized surgical procedure, machine, incision type, and intraocular lens implantation; comprehensive intraoperative and postoperative parameter assessment.

    • Main Results:

    • No statistically significant differences were observed in visual acuity, astigmatism, corneal thickness, or endothelial cell count between the groups.
    • Bimanual microphacoemulsification demonstrated a statistically significant reduction in the total volume of balanced salt solution (BSS) used (P = .004).
    • Total surgical time was significantly shorter with the bimanual technique compared to the coaxial method (P = .045).

    Conclusions:

    • Both bimanual microphacoemulsification and coaxial miniphacoemulsification are safe and effective cataract surgery techniques.
    • Bimanual microphacoemulsification offers advantages by requiring less BSS and reducing overall surgical time.
    • These findings suggest bimanual microphacoemulsification may be a more efficient approach in specific cataract cases.
