“…Migration was classified as decentration and displacement based on our previous work. [ 9 ] All six patients had an inferotemporal displacement of the implant with the implant palpable anterior to the inferior orbital rim and consequent shallowing of the inferior fornix. They had inability to retain a custom ocular prosthesis (COP) or achieve a satisfactory centration of the prosthesis after maximal prosthesis modification by an expert ocularist.…”

Purpose:To describe the outcomes of a patient-specific implant (PSI), fabricated using a three-dimensional (3D) printed orbital template and placed in the basin of the inferior orbital fissure to correct inferotemporally migrated spherical orbital implant.Methods:This is a single-center, prospective, consecutive, interventional, case series of six patients, with non-porous, spherical, orbital implant migration that underwent implant recentration surgically with a novel technique. Migration was subclassified either as decentration that did not affect the prosthetic retention or as displacement that affected the prosthetic retention in the eye socket. Only implant displacements were treated. The primary outcome measure was centration of the implant clinically and radiologically, with ability to retain the prosthesis.Results:At a mean follow-up of 21 months, all six orbital spherical implants remained centered. There were no cases of extrusion, exposure, or migration of either implants. There were no cases of PSI displacement. Additional procedures to optimize the aesthetic outcome of the customized ocular prosthesis (COP) required were simultaneous fornix formation suture in three patients, subsequent fornix formation with mucus membrane graft in two patients, and levator resection and sulcus hyaluronic acid gel injection in one patient each. The mean PSI implant weight was 2.66 ± 0.53 g. The mean COP weight was 2.2 ± 0.88 g postoperatively. The median patient satisfaction with the procedure was 9 on 10.Conclusion:A 3D printing-assisted PSI placed in the basin of the inferior orbital fissure allows recentration of the migrated implant over a follow-up of 21 months without complications.

“…This technique allows for the placement of larger orbital implants and helps in reducing the weight of the prosthesis; migration tends to be lower with porous implants, although nonporous implants can be a reasonable alternative for lower cost. 46 According to a recent study, a 3D printing-assisted custom made implant, positioned in the basin of the inferior orbital fissure, allows recentration of the implant and better prosthetic rehabilitation. 47…”

Anophthalmic socket syndrome determines functional deficits and facial deformities, and may lead to poor psychological outcomes. This review aims to comprehensively evaluate the features of the syndrome, based on literature review and authors’ clinical and surgical experience. An electronic database (PubMed,MEDLINE and Google Scholar) search of all articles written in English and non-English language with abstract translated to English on anophthalmic socket syndrome was performed. Data reviewed included demographics, presentations, investigations, management, complications and outcomes. Different types of orbital implants were evaluated; the management of implant exposure was examined; different orbital volume enhancement procedures such as secondary implantation, subperiosteal implants and the use of fillers in anophthalmic patients were described; the problems related to socket contraction were outlined; the treatment options for chronic anophthalmic socket pain and phantom eye syndrome were assessed; the most recent advances in the management of congenital anophthalmia were described. Current clinical evidence does not support a specific orbital implant; late exposure of porous implants may be due to pegging, which currently is seldom used; filler absorption in the orbit appears to be faster than in the dermis, and repeated treatments could be a potential source of inflammation; socket contraction results in significant functional and psychological disability, and management is challenging. Patients affected by anophthalmic socket pain and phantom eye syndrome need specific counseling. It is auspicable to use a standardized protocol to treat children affected by clinical congenital anophthalmia; dermis fat graft is a suitable option in these patients as it helps continued socket expansion. Dermis fat graft can also address the volume deficit in case of explantation of exposed implants and in contracted sockets in both children and adults. Appropriate clinical care is essential, as adequate prosthesis wearing improves the quality of life of anophthalmic patients.

“…[ 2 ] This makes it important for us to understand the concept of making scleral flaps during evisceration and ideal sizing of implants to achieve a symmetric fullness of the superior sulcus and avoid anophthalmic ptosis. [ 3 ] Along with this, one of the most important factors that is sub-optimally addressed is the cosmetic outcome of the prosthesis itself. [ 4 ] This puts an emphasis on the development of a metric to assess the aesthetic outcome of an anophthalmic socket incorporating all of these factors.…”

Effect of Optic Nerve Disinsertion During Evisceration on Nonporous Implant Migration: A Comparative Case Series and a Review of Literature

Abstract: The rate of nonporous implant migration due to optic nerve disinsertion is not statistically or clinically significant in evisceration with optic nerve disinsertion, allowing placement of a larger implant and fabrication of a custom ocular prosthesis with an ideal weight.
