AIM: To evaluatethe efficacy and safety of improved lacrimal excision surgery in patients

METHODS:A retrospective study of 92 chronic dacryocystitis patients(92 eyes)undergoing common lacrimal excision surgery and improved lacrimal excision surgery from September 2006 to March 2012 was carried out. The patients(36 males, 56 females)with the age of 71-90 years(average 77.20±11.08)were randomly divided into control group(46 eyes)and experimental group(46 eyes). The patients in control group performed common lacrimal excision surgery and those in experimental group received improved lacrimal excision surgery. The efficacy and safety of two groups were analyzed.

RESULTS: The duration of improved lacrimal excision surgery(5min)was shorter than that of common lacrimal excision surgery(20min). No serious complications were presented in experimental group.

CONCLUSION:With the advantages of lighter trauma, less bleeding, shorter duration and fewer complications, the improved lacrimal excision surgery is effective and safe, especially suitable for the elderly with chronic dacryocystitis, who's at poor body condition, cannot tolerate longer operative time and has larger trauma.
