Summary

Aqualase technology effectively removes softer cataracts (nuclear sclerosis 2+ or less) with a brief learning curve. However, ultrasound phacoemulsification remains superior for firmer cataracts.

Area of Science:

  • Ophthalmology
  • Surgical Technology

Background:

  • Cataract extraction is a common surgical procedure.
  • Phacoemulsification is the current standard for cataract removal.

Purpose of the Study:

  • To evaluate the efficacy and safety of Aqualase technology for cataract extraction.
  • To compare Aqualase with traditional phacoemulsification for different cataract densities.

Main Methods:

  • A total of 33 patients underwent cataract surgery using Aqualase via a 3.2-mm corneal incision.
  • Nuclear sclerosis grade, removal technique, and complications were recorded.
  • Postoperative clinical parameters were collected and analyzed.

Main Results:

  • Aqualase efficiently removed cataracts up to nuclear sclerosis 2+.
  • Conversion to ultrasound phacoemulsification was needed for one case with a 2+ nucleus.
  • Two posterior capsule ruptures occurred, one unrelated to Aqualase.
  • 96% of patients without comorbidities achieved 6/9 or better vision postoperatively.

Conclusions:

  • Aqualase offers theoretical advantages for softer cataracts due to its non-mechanical tip, potentially reducing posterior capsule risk.
  • The technology is not entirely capsule-friendly, as rupture is possible during aspiration.
  • While adjustments are needed, Aqualase has a short learning curve similar to phacoemulsification.
  • Ultrasound phacoemulsification remains the preferred method for firmer cataracts.
