Lower eyelid retraction improved with dermal regeneration matrix template

SAN FRANCISCO — A bilayer dermal regeneration matrix template improved lower eyelid retraction in patients undergoing repair, Cat Burkat, MD, said in a presentation at the American Society of Ophthalmic Plastic and Reconstructive Surgery meeting.
“Lower eyelid retraction may recur despite appropriate surgical techniques and lead to further fibrosis that limits repair,” Burkat told Healio/OSN. “The bilayer dermal regeneration template can be considered in primary complex or recurrent cases.”
Burkat described the procedure as a transconjunctival approach below the tarsus with the elliptical/crescent bilayer dermal regeneration matrix template sutured between the tarsus and the recessed inferior retractors.
“The meshed dermal layer of collagen and glycosaminoglycans forms a new biointegrated layer inferior to the tarsus to prevent recurrence, while the more rigid silicone layer vertically bolsters the eyelid against gravity until it is removed,” she said.
Of 16 patients who underwent eyelid retraction repair using the bilayer implant for either upper or lower eyelid surgery, preoperative symptoms resolved and retraction improved in 95.2% of those who underwent lower eyelid repair. Superior fornix depth improved in those who underwent upper eyelid retraction repair.
“The spacer is surprisingly well-tolerated despite its rigidity and has demonstrated excellent surgical results in our series,” Burkat said. – by Patricia Nale, ELS
