BVI's Extend™ Absorbable Synthetic Punctal Implants are short-term implants (max. 3 months) designed to be inserted through the punctal opening into the canaliculus in order to block tear drainage through the lacrimal drainage system. The implants are made from an absorbable copolymer of glycolic acid and trimethylene carbonate. The implants are dyed with D&C Green Number 6. Extend™ Absorbable Synthetic Punctal Implants are available in three diameters: 0.3mm, 0.4mm and 0.5mm.
Extend™ Absorbable Synthetic Punctal Implants are intended for temporary use in patients experiencing dry eye symptoms such as redness, burning, reflex tearing, itching or foreign body sensations which can be relieved by blockage of the canaliculus. They may be used in the treatment of dry eye syndrome and the dry eye components of various ocular surface diseases. When indicated, Extend™ Absorbable Synthetic Punctal Implants may also be used after surgery on the eye to prevent complications due to dry eye and to enhance the retention of ocular medication on the eye.
