The diode laser effectively treats tearing caused by nasolacrimal duct obstruction, with a 74.3% success rate after 12 months. This minimally invasive procedure offers a promising solution for patients experiencing chronic tearing.
Area of Science:
- Ophthalmology
- Laser Surgery
- Tear Duct Disorders
Background:
- Nasolacrimal duct obstruction (NLDO) causes significant tearing and reduced quality of life.
- Endocanalicular dacryocystorhinostomy (DCR) aims to restore tear drainage.
- Minimally invasive techniques are sought to improve DCR outcomes.
Purpose of the Study:
- To assess the efficacy of the diode laser in performing endocanalicular dacryocystorhinostomy.
- To evaluate the diode laser's effectiveness in resolving symptoms of tearing due to NLDO.
Main Methods:
- A prospective case series of patients with tearing and NLDO.
- Diode laser endocanalicular dacryocystorhinostomy was performed.
- Outcomes measured included subjective tearing improvement and objective nasolacrimal system patency over 12 months.
Main Results:
- Eighty-eight percent of patients showed initial improvement in tearing after one week.
- At 12 months, 74.3% of cases achieved complete resolution of tearing and maintained nasolacrimal system patency.
- No significant complications were reported, with success defined by symptom improvement and patency.
Conclusions:
- Diode laser endocanalicular dacryocystorhinostomy demonstrates a favorable success rate for treating NLDO.
- Subjective tearing improvement correlates with objective nasolacrimal system patency.
- The diode laser is an effective option for endocanalicular dacryocystorhinostomy.
