Design outcomes

Primary

Measure	Time frame
Comparison of success rate in modified surgical intervention methods with probing method with turbine fracture and Crawford implantation in the treatment of congenital nasolacrimal duct obstruction. Timepoint: patients will be examined for the success of the intervention as well as the complications of the interventionm, a day after the intervention,. At 3 months and 6 months after the surgery, patients will be re-evaluated for the visual system and fluorocin test will be performed, and the results of follow-up and examination at times 0, 3 and 6 (months) will be evaluated and compared. Method of measurement: At each follow-up, patients will undergo a complete evaluation of the visual system and perform a fluorescein test.	—
