Phacoemulsification surgery using the nondominant hand yields successful outcomes for patients with against-the-rule astigmatism. This technique offers an alternative surgical approach without requiring position adjustments.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Age-related cataracts are a leading cause of visual impairment.
  • Phacoemulsification is the standard surgical procedure for cataract removal.
  • Managing against-the-rule astigmatism during cataract surgery is crucial for visual outcomes.

Purpose of the Study:

  • To evaluate the efficacy of on-axis phacoemulsification using the nondominant hand.
  • To assess surgical outcomes in patients with against-the-rule astigmatism.
  • To determine if surgeon positioning (head end vs. temporal) impacts surgical results.

Main Methods:

  • Eighty eyes with age-related cataracts and against-the-rule astigmatism underwent phacoemulsification.
  • Patients were divided into four groups based on surgeon's hand (dominant/nondominant) and position (head end/temporal).

  • Key parameters including visual acuity, surgically induced astigmatism, and intraocular pressure were evaluated post-surgery.

    • Main Results:

    • Phacoemulsification time and power were comparable across all four surgical groups.
    • No significant differences were observed in surgically induced astigmatism, endothelial cell loss, or intraocular pressure.
    • Both uncorrected and best-corrected visual acuities at 3 months were similar among the groups, indicating good visual outcomes.

    Conclusions:

    • Phacoemulsification can be successfully performed using the nondominant hand, achieving good surgical outcomes.
    • This technique provides a viable alternative, eliminating the need for the surgeon to reposition during on-axis phacoemulsification.
    • The findings support the use of nondominant hand phacoemulsification as a safe and effective surgical option.
