ABSTRACT
Objective: to compare the lachrymal duct probing technique after canalicular dilation canalicular with viscoelastic gel or with direct probing.Methods: prospective, analytical and non-concurrent cohort study carried out in 136 eyes from patients with congenital nasolachrymal duct obstruction, who were seen at the ophthalmological pediatric service in "Pepe Portilla" teaching pediatric hospital located in Pinar del Rio and who underwent lachrymal duct probing in the period of January, 2008 through July, 2013. Two study groups were formed with 68 eyes each, one treated with direct probing, and the other with previous dilation of the excretory duct with viscoelastic gel.
Results: the first group showed some complications in 45,59 % of patients; 54,41 % recovered and 32,35 % were reoperated. In the second group, 97,92 % managed to recover without complications, including 6 eyes from patients older than 3 years. It was necessary to re-operate a patient.
Conclusions: nasolachrymal duct probing after dilation with Healon minimizes complications and need for reoperation, thus facilitating its use in patients aged over 3 years.
