Dry eye syndrome (DES) is a relatively common condition with signs and symptoms varying from light irritation to functional blindness as a result of corneal opacification. The disorder generally occurs in subjects over 40 years of age. DES management is related to the severity of the symptoms. In most cases treatment focuses on tear substitution.
However, permanent punctal occlusion may be indicated for patients in which these conventional therapies fail. The procedure is simple and can be performed in the office. To cauterize and close the punctum, a high-frequency low-temperature surgical device and a specifically designed electrode [Chedly Punctal Occluder (CPO)] are employed. The very same CPO electrode, may be utilized to achieve dilation of the punctum and sealing of the the lumen of the lacrimal duct.
