Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Conventional cataract surgery utilizes cortical-cleaving hydrodissection.
  • Hydrodissection can lead to complications like posterior capsule rupture and hemorrhage.

Purpose of the Study:

  • To describe a new hydrodissection-free phacoemulsification technique.
  • To reduce hydrodissection-related complications in cataract surgery.

Main Methods:

  • Developed a mechanical cortical-cleaving dissection technique during phacoemulsification.
  • Eliminated the need for conventional hydrodissection.

Main Results:

  • The hydrodissection-free technique was effective in 547 of 550 cataract eyes.
  • Prevented high endocapsular pressure and associated complications.
