ABSTRACT
This chapter is inspired by US Patent 7,625,404, Surgical Correction of Ptosis by Polymeric Artificial Muscles. It is also inspired by publication US000007625404B220091201 (https://www.pat2pdf.org" xmlns:xlink="https://www.w3.org/1999/xlink">pat2pdf.org).
A surgical procedure is described for the restoration of eyelid function in individuals suffering from ptosis or upper eyelid droop syndrome, which makes a patient unable to fully raise an eyelid. The surgical procedure includes implantation and suturing of eye drop (pH) activated and actuated fibrous contractile and expansive artificial muscles. Thus, pH-active hydrogels of polyacrylonitrile (PAN) artificial muscles, which are surgically implanted and sutured under the superior palpebral conjunctiva. This happens in a serpentine parallel configuration with respect to the tarsal (meibomian) glands of the upper eyelid and anchored to the tissues of superior fornix.
The present chapter is generally related to the restoration of eyelid function and correction of ptosis.
