Influence To The Lacrimal Duct Obstruction Patient’s Ocular Surface Before And After Transcanalicular Laser And Silicone Lacrimal Drainage Tube Implant

Objective To study the influences to the ocular surface of patients withlacrimal duct obstruction before and after tanscanalicular laser and siliconelacrimal drainage tube implant.Methods Thirty patients who diagnosed of lacrimal duct obstructionunderwent tanscanalicular laser and silicone lacrimal drainage tubeimplantation.The status of their ocular surface was evaluated in anobservational case series,with the help of dry eye questionnaire（DEQ）,breakup time （BUT）, Schirmer I test(SIt),fluoresceinstaining(FL),tear ferning test(TFT),lissamine green staining(LG), impressioncytology of conjunctiva(IC)，in pre-operative、one mongth after surgery andextubation.Results Epiphora was relieved apparently after the surgery in patients.SIt wasincreased one month after the surgery,but it was decreased after extubationcomparede to pre-operative.There’s no apparent changes in BUT，scores ofFL and LG,grade of TFT and conjunctival goblet cells.Gender,patients age didnot affect changes to the ocular surface before and after the surgery.Conclusion There’s no apparent influence to the ocular surface of patientswith lacrimal duct obstruction before and after tanscanalicular laser andsilicone lacrimal drainage tube implantation.The surgery can improve the symptoms in patients with epiphora and improve the quality of their life.
