Evaluation by ophthalmologist ± ENT consultation
CT scan or dacryocystography to assess blockage
Tear flow test before surgery
Local or general anesthesia as required
Pain management with appropriate medications
Wound care and nasal hygiene post-op
Patient education on nasal rinsing and infection prevention
3. Duration of hospitalization
Usually outpatient (same-day discharge(
Overnight stay may be needed in complex cases
