Intracameral lidocaine effectively dilates pupils for eye surgery without traditional drops. This method offers faster recovery and eliminates cardiac risks associated with other mydriatic agents.

Area of Science:

  • Ophthalmology
  • Surgical Techniques
  • Pharmacology

Background:

  • Preoperative mydriatic eyedrops are standard for pupil dilation in cataract surgery.
  • Traditional mydriatics can carry risks, including cardiac side effects and delayed pupil recovery.

Purpose of the Study:

  • To present a novel technique using intracameral lidocaine for pupil dilation during ophthalmic surgery.
  • To evaluate the efficacy and safety of intracameral lidocaine as a mydriatic agent.

Main Methods:

  • Topical lidocaine hydrochloride 1% applied to the ocular surface.
  • Intracameral injection of lidocaine via a side-port incision.
  • Addition of epinephrine to balanced salt solution irrigation during phacoemulsification.

Related Experiment Videos

Main Results:

  • Adequate pupil dilation (mydriasis) achieved within 90 seconds.
  • Pupil dilation maintained or increased throughout the phacoemulsification procedure.
  • Faster return of pupil to normal size and reactivity postoperatively.

Conclusions:

  • Intracameral lidocaine provides effective and rapid pupil dilation for ophthalmic surgery.
  • This technique eliminates cardiac risks of topical mydriatics and reduces patient waiting times.
  • Intracameral lidocaine promotes faster recovery of normal pupil function and reduces keratopathy risk.
