Area of Science:

  • Ophthalmology
  • Surgical Anesthesia

Background:

  • Phacoemulsification is a common cataract surgery technique.
  • Effective anesthesia is crucial for patient comfort and surgical success.
  • Existing anesthesia methods may involve complex procedures or longer administration times.

Purpose of the Study:

  • To describe a simplified anesthesia technique for sutureless, small-incision, one-port phacoemulsification.
  • To evaluate the efficacy and applicability of this rapid anesthesia method.

Main Methods:

  • Intravenous sedation with midazolam and propofol.
  • Application of a tetracaine- or preservative-free lidocaine-soaked sponge for localized anesthesia.
  • Intracamerally injection of preservative-free lidocaine for intraocular anesthesia.

Main Results:

  • The described technique is rapid, taking approximately 10 seconds to complete.
  • It is effective for all cataract types.
  • The technique is compatible with all phacoemulsification approaches.

Conclusions:

  • This simplified anesthesia technique offers an efficient and effective option for cataract surgery.
  • It can be readily integrated into various phacoemulsification procedures.
  • Further studies reported results in a study population.
