Journal Title: MedPulse -International Medical Journal - Year 2014, Vol 1, Issue 10
Abstract
Aim: To test the long term efficacy and safety of transcanalicular laser DCR. Material and Methods: A prospective, interventional, non randomized, non comparative clinical study was conducted in ophthalmology department of tertiary care hospital of Nagpur from August 2009 to July 2012 on 74 cases of nasolacrimal duct obstruction [NLDO]. After complete ophthalmic and rhinologic examination, all patients underwent transcanalicular lasar DCR using 980nm diode laser with power 6W and pulse length 90ms to create ostotomy of minimum 5 to 6 mm in size followed by application of diluted mitomicine C [0.4 mg / ml] at the ostium site for 5 minutes. Results: 74 sucsessive transcanalicular laser DCR were performed in 72 patients; 46 females and 26 males; mean age 54 years [range 13 to 68 years], mean procedure time of 13 minutes [ range 8 to 35 minutes], average total amount of delivered laser energy 245 J [ range 195 to 685 J] and the mean follow up time was 6 months [ 3 to 12 months]. We observed absence of epiphora and patent nasolacrimal passage in 46 out of 74 cases i.e. success rate of 62.16 %. Conclusion: Though Transcanalicular laser DCR using diode laser is relatively simple, elegant and effective outpatient procedure, continued advances in the technology and techniques are needed to bring this simple procedure on the forefront of lacrimal surgery.
