Selective hydrodissection precisely separates cataract lens layers. This technique enables smaller incisions and facilitates advanced cataract surgery techniques like phacoemulsification.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Cataract Surgery

Background:

  • Cataract surgery involves removing the clouded lens.
  • Traditional methods may require larger incisions and complex maneuvers.
  • Hydrodissection is a known technique for lens separation.

Purpose of the Study:

  • To describe selective hydrodissection for precise cataract lens lamella separation.
  • To highlight the benefits of selective hydrodissection in cataract surgery.
  • To present selective hydrodissection as a preparatory step for phacoemulsification.

Main Methods:

  • Balanced salt solution is injected via cannula into specific lens layers.
  • Selective hydrodissection targets desired anatomical planes for lamellar separation.

  • Enables separate removal of the hard-core nucleus and epinucleus.

    • Main Results:

    • Allows hydroexpression of the hard-core nucleus as a distinct unit.
    • Facilitates aspiration or hydroexpression of the epinucleus as a whole.
    • Enables smaller capsulorhexis and limbal incisions.

    Conclusions:

    • Selective hydrodissection offers enhanced control in cataract extraction.
    • The technique supports stitchless surgery in planned extracapsular cataract extraction.
    • It serves as a valuable intermediate step for learning phacoemulsification.
