title: Prilocaine versus lignocaine for minor lid procedures.
abstract: OBJECTIVE
  To determine whether prilocaine is a more comfortable local infiltration anaesthetic agent than the more widely used lignocaine for minor eyelid procedures.
  
  
  METHODS
  A prospective randomised study was undertaken to compare the discomfort between local infiltration of plain 2% prilocaine versus its equivalent, plain 2% lignocaine. One hundred and twenty-five patients were recruited. Pain was assessed subjectively using a visual analogue pain score, graded from 0 to 10.
  
  
  RESULTS
  The mean pain score for the prilocaine group was 1.82 compared with 3.19 for the lignocaine group. Using the Mann-Whitney U-test for significance, U = 1236.5; p < 0.001.
  
  
  CONCLUSIONS
  Prilocaine is a more comfortable local infiltration anaesthetic agent than lignocaine when used for minor eyelid procedures.
