Cataract extraction under topical subconjunctivital local anaesthesia combined with neuroleptanalgesia

Abstract EN

Local anaesthesia for ophthalmic surgical techniques is achieving prevalence now.

Various local procedures were described in the literature including retrobulbar, peribulbar, subconjunctival and topical anaesthesia.

This study endeavor to ascertain the efficacy of lidocaine topical-subconjunctival anesthesia technique combined with neuroleptic sedation-analgesia consisting of fentanyl and droperidol in cataract surgery, and to test patient's and surgeon's satisfaction with this method.

Sixty five patients with mature cataract age range 55-70 years were scheduled for cataract extraction.

Patients were 36 male and 29 female.

Topical and subconjunctival local anaesthesia was supplemented by intravenous sedative and analgesic medication consisting of 50g fentanyl and 2.5 mg droperidol.

A special patient's pain scoring system used in this study with another intraoperative surgeon's satisfaction score to test the reliability of this method.

All patients had successful cataract extraction with an average surgery time of 20-25 minutes.

Patients had minimal or no movement during surgery.

No patient required additional supplement of anaesthesia as there were no intolerable pain.

No postoperative complications.

Cataract surgery can be safely and effectively performed by surgeons converting to topical anesthesia using this method.
