Subconjunctival anesthesia (SCA) in cataract surgery is safe and effective. Most patients experienced no pain during surgery, with good visual acuity achieved shortly after the procedure.

Area of Science:

  • Ophthalmology
  • Surgical Anesthesia

Background:

  • Cataract surgery is a common procedure.
  • Effective anesthesia is crucial for patient comfort and surgical success.
  • Subconjunctival anesthesia (SCA) is an alternative anesthetic technique.

Purpose of the Study:

  • To evaluate the efficacy and safety of subconjunctival anesthesia (SCA) for phacoemulsification cataract surgery.
  • To assess patient-reported pain levels and postoperative outcomes following SCA.

Main Methods:

  • Analysis of patient questionnaires and medical records from 133 consecutive patients undergoing scleral tunnel phacoemulsification cataract surgery with SCA.
  • Preoperative and intraoperative medication use was documented.

Main Results:

  • 90% of patients reported no pain during surgery.
  • 69% of patients achieved uncorrected visual acuity of 20/200 or better within 35 minutes post-surgery.
  • Common postoperative complaints included pain, patching, and headache.

Conclusions:

  • Subconjunctival anesthesia is a safe and effective anesthetic technique for cataract surgery.
  • SCA offers a minimally invasive approach with high patient satisfaction regarding intraoperative pain.
  • Further research may explore optimizing postoperative pain management.
