Hydrodissection significantly improves intraoperative performance during cataract surgery. This technique makes nucleus and cortex removal easier and faster, reducing fluid usage and enhancing surgical efficiency.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Phacoemulsification is a common surgical procedure for age-related nuclear cataracts.
  • Intraoperative challenges can arise during nucleus and cortex removal.
  • Hydrodissection is a technique used to separate the cataract nucleus from the surrounding cortex.

Purpose of the Study:

  • To evaluate the impact of multiquadrant hydrodissection on intraoperative performance during phacoemulsification.
  • To assess the effect of hydrodissection on nucleus and cortex removal times, fluid usage, and ease of manipulation.

Main Methods:

  • A prospective study involving 86 eyes with grade 1-3 nuclear cataracts.
  • Random assignment to either multiquadrant hydrodissection (+HD) or no hydrodissection (-HD) groups.

  • Assessment of nucleus/cortex removal time, fluid consumption, and subjective ease of nucleus rotation and cortical cleanup.

    • Main Results:

    • The +HD group showed significantly reduced cortex removal time (79 sec vs. 220 sec) and total fluid usage (312 mL vs. 422 mL).
    • Nucleus rotation was significantly easier in the +HD group (100% easy vs. 31.57% failed rotation).
    • Cortical cleanup was rated as very easy or easy in 100% of +HD eyes compared to 52.63% in the -HD group.

    Conclusions:

    • Multiquadrant cortical-cleaving hydrodissection enhances intraoperative efficiency in phacoemulsification.
    • This technique simplifies nucleus and cortex removal, leading to faster and easier cataract surgery.
    • Hydrodissection is a valuable adjunct for improving surgical outcomes in nuclear cataract cases.
