Summary

Whitestar technology demonstrated superior performance for hard cataracts during bimanual microincision phacoemulsification. Multiburst mode proved less suitable, showing higher ultrasonic energy use and complications.

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Cataract Surgery

Background:

  • Hard cataracts present surgical challenges in phacoemulsification.
  • Bimanual microincision phacoemulsification aims to minimize ocular trauma.
  • Different ultrasonic modes may impact surgical outcomes and safety.

Purpose of the Study:

  • To compare the efficacy and safety of Multiburst mode, Shortpulse mode, and Whitestar technology on the Sovereign platform.
  • To evaluate these modes in treating hard cataracts using bimanual microincision phacoemulsification.

Main Methods:

  • 101 eyes with Grade 3-4+ hard cataracts were randomized into three treatment groups.
  • Phacoemulsification was performed using Multiburst, Shortpulse, or Whitestar modes.
  • Outcomes measured included average power, ultrasonic time (US Time), effective phaco time, complications, visual acuity, and endothelial cell loss.

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

Published on: July 7, 2023

Main Results:

  • Whitestar technology used the highest average ultrasonic power, followed by Shortpulse.
  • Multiburst mode exhibited the longest US Time, effective phaco time, and highest corneal endothelial cell loss.
  • Whitestar group showed the lowest US Time and endothelial cell loss; Multiburst group had wound burn and anterior chamber fluctuations.

Conclusions:

  • Whitestar technology demonstrated the best performance for hard cataracts in this study.
  • Multiburst mode was found to be relatively unsuitable for treating hard cataracts with this technique.
