In the in vivo stability test using dummy devices, fundus and
ocular observation along with OCT imaging were performed
for a year after the implantation. The microscopic image in
Fig. 12(d) shows the device during the surgery after the attachment
of the device using two episcleral suturing holes before
recovering the conjunctiva, whereas Fig. 12(e) shows the same
device after a year of implantation. The recovered conjunctiva
was well preserved without observation of any adverse effects
such as inflammation and protrusion of the device. A fundus
image of Fig. 12(f) showed that the implanted array had not
migrated or induced vitreous inflammation. A representative
OCT image in Fig. 12(g) shows that the retinal structure containing
the LCP-based electrode array was well preserved for
the postoperative one-year period without any choroidal retinal
inflammation or structural deformations.
