Area of Science:

  • Ophthalmology
  • Anesthesia

Background:

  • Cataract surgery traditionally uses local or general anesthesia.
  • Retrobulbar injections, while effective, carry risks like hemorrhage and globe perforation.

Purpose of the Study:

  • To evaluate the feasibility of a novel local anesthesia (NR method) for extracapsular cataract extraction.
  • To mitigate risks associated with retrobulbar injections, such as hemorrhage.

Main Methods:

  • Extracapsular cataract extraction with lens implant performed on 175 eyes.
  • Local anesthesia administered via amethocaine drops and subconjunctival injection, excluding retrobulbar block.

Main Results:

  • The NR method proved satisfactory for cataract surgery.
  • No significant procedural difficulties were encountered.
  • Visual outcomes were favorable and comparable to general anesthesia.

Conclusions:

  • The NR method is a safe and effective alternative anesthesia for cataract surgery.
  • This technique avoids the complications of retrobulbar injections.
  • Patient acceptance was high, suggesting preference over conventional methods.
