Summary

General anaesthesia now a days is not the first choice in phakic intra ocular lens surgery (Phakic IOL) , the short duration of the surgery, general anaesthesia complications, decrease the length of hospital stay and decreasing the costs direct the interest to the regional anaesthesia By the time the traditional retro and peribulbar injections recede to a newer techniques that is safer and cheaper, sub tenon's block using a blunt needle took over due to the more safety profile Even though, still serious problems can occur specially in patients with long axial length.

Deep topical fornix nerve block anaesthesia (DTFNB) and topical anaesthesia gradually took over with promising and successful results, decreasing length of hospital stay and increasing patient satisfaction and fewer margins of complications.

In this study the investigators compared topical anaesthesia alone with DTFNBA in patients undergoing posterior chamber phakic IOL surgery (Visian ICL).

Conditions

  • Local Anesthesia
  • Satisfaction

Interventions

DRUG

2% tetracaine local anaesthetic drops

topical anaesthetic drops

DRUG

0.5% bupivacaine

was performed using two sponges (2x3mm) soaked with 0.5% bupivacaine, applied deep in the conjunctival fornices after anaesthetising the conjunctiva with tetracaine local anaesthetic drops. The sponges were removed after 15 minutes. The anaesthetic effect was tested by grasping the limbus with Castroviejo 0.12 tissue forceps.
