This study introduces a novel phacoemulsification technique for soft and medium-hard cataracts. The method aims to reduce ultrasound time and improve surgical safety during cataract removal.

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Cataract surgery is a common procedure.
  • Phacoemulsification is the standard method for cataract removal.
  • Reducing phacoemulsification time and enhancing safety are key goals in cataract surgery.

Purpose of the Study:

  • To describe a modified phacoemulsification technique.
  • To decrease phacoemulsification time.
  • To enhance the safety of cataract surgery for soft and medium-hard cataracts.

Main Methods:

  • Conventional hydrodissection and hydrodelamination are performed.
  • A 15- or 30-degree phaco tip is used at the peripheral lens, nucleus-epinucleus interface.
  • The technique involves controlled aspiration, limited ultrasound energy (15-25%), linear aspiration power (up to 250 mmHg), and rotational lens manipulation with a modified manipulator.

Main Results:

  • The described technique facilitates efficient emulsification of soft and medium-hard cataracts.
  • It allows for reduced phacoemulsification time.
  • The method enhances surgical safety by minimizing ultrasound energy and improving lens control.

Conclusions:

  • This modified phacoemulsification technique offers a safe and efficient approach for soft and medium-hard cataracts.
  • The technique can lead to decreased operative time and improved patient outcomes.
  • Further studies may explore its efficacy in harder nuclear densities.
