title: Carbon dioxide (CO2) laser third eyelid excision: surgical description and report of 7 cases.
abstract: OBJECTIVE
  To describe a novel technique for third eyelid (TEL) excision using a carbon dioxide (CO2) laser.
  
  
  METHODS
  Prospective.
  
  
  METHODS
  The procedure was performed on six canine patients and one feline patient.
  
  
  METHODS
  The laser was set to 6 Watts (W) of power and a linear continuous setting. Forceps were used to elevate the TEL and, with a protective shield covering the cornea, the base was cut and cauterized simultaneously. Minimal to no hemorrhage was observed, and the conjunctiva was left to heal by second intention.
  
  
  RESULTS
  Seven patients underwent unilateral surgical TEL excision. All patients had suspected neoplasms affecting either the glandular tissues or conjunctival surfaces of the TEL. Clean surgical margins were achieved in all but one patient. All surgical sites were considered healed by 14 days showing mild-to-moderate conjunctival hyperemia and accumulation of mucoid discharge at the ventronasal fornix. One patient experienced postoperative keratoconjunctivitis sicca. Prolapse of orbital fat was not observed in any patient.
  
  
  CONCLUSIONS
  Use of CO2 laser appears to be an efficient and effective means for surgical third eyelid removal with excellent postoperative comfort and minimal complications.
