“…In the field of ophthalmology, AM applications are, conceptually speaking, not very different from the ones used in other fields of medicine. In scientific literature, there have been described works related with the printing of the first artificial cornea [49], fetal face modeling [50], intraocular lenses [51][52][53][54] or rigid permeable gas contact lenses [55], ocular prosthesis [56][57][58][59], intraocular tumor visualization [60], medical staff education [61,62], tissue bio-printing [63][64][65], printing of surgical instruments [66] or medical devices [67] or goggles for patients with deformations of unusual facial features [68]. However, we have not found proof of the use of the AM as a tool for improving doctor-patient communication strategies in KC disease.…”

Additive manufacturing is a vanguard technology that is currently being used in several fields in medicine. This study aims to evaluate the viability in clinical practice of a patient-specific 3D model that helps to improve the strategies of the doctor-patient assistance. Data obtained from a corneal topographer were used to make a virtual 3D model by using CAD software, to later print this model by FDM and get an exact replica of each patient’s cornea in consultation. Used CAD and printing software were open-source, and the printing material was biodegradable and its cost was low. Clinic users gave their feedback by means of a survey about their feelings when perceiving with their senses their own printed cornea. There was 82 surveyed, 73.8% (9.74; SD: 0.45) of them considered that the model had helped them a lot to understand their disease, expressing 100% of them their intention of taking home the printed model. The majority highlighted that this new concept improves both quality and clinical service in consultation. Custom-made individualized printed models allow a new patient-oriented perspective that may improve the communication strategy from the ophthalmologist to the patient, easing patient’s understanding of their asymmetric disease and its later treatment.

“…[287] Reconstruction of the eye socket and surrounding tissue involves similar processes as with facial prostheses. In many cases, magnetic resonance imaging and computed tomography are used to capture patient morphology, [290,291] although the use of a 3D facial scanner combined with an intraoral scanner has also been employed. [220] Following prosthesis production, aesthetic can be hand painted and coated using a clear acrylic.…”

past 30 years, [12,13] it is only the last decade that has seen its rapid development as part of the fourth industrial revolution. [14] This change in practice is evidenced by the significant fraction of recent literature describing advances in 3D printed prostheses, including technological advances [4,15-18] and clinical reports. [19,20] Further innovations involving collaborations between clinicians, academics, and industry, promise even greater capabilities. The future will see 3D printers that can mix materials as desired during fabrication [21] and those that can 3D print organic semiconductors and piezoelectric polymers for sensing and bionics [22-24] (Figure 1). This report is focused on polymers for soft tissue, external, personalized, prosthetics with clinical applications for the ear, [25] nose, [26] eye, [27] face, [28] breast, [29] and hand. [30] The characteristics of both traditional and 3D printable polymeric materials, as well as current advanced manufacturing technologies and those in development, are also reviewed. The earliest evidence of prosthetics dates back to ≈2300 BC, where Egyptian mummies have been discovered with eye, nose, and genital reconstructions fashioned from plaster packed with mud, sand, linen, butter, or soda (Figure 1). [31] Wood, cloth, natural waxes, resins, and metals were later used as the material of choice for rudimentary prostheses. [32] Prostheses remained relatively unchanged for thousands of years until the 16th century, where prosthetic noses and eyes were made from parchment, wax, wood, hard rubber, gold, silver, and copper. [33] Metals continued as a fundamental material throughout the 19th century, largely due to their ability to be shaped and molded as needed. [34,35] One of the first polymers to be used in prosthetics, poly(methyl methacrylate) (PMMA), was developed in response to the glass shortages in the World Wars of the 20th Century. [36] This polymer went on to become the most common prosthetic material of the time, and still finds use today in artificial eyes [33] and prosthetic substructures. [37] Further innovations in the 20th century produced many new polymers, such as vinyls, copolymers, plastisols, and one of the most significant materials in prosthetics, silicone. [38] Discovered in the early 1900s by Fredrick Kipping, silicone was first used in prosthetics by George W Barnhart in 1960. [39] This versatile polymer remains a primary prosthetic material today due to its soft tissue-like properties, ease of manipulation, chemical inertness, durability, and excellent biocompatibility. [40,41] The search for alternative materials Millions of people worldwide experience disfigurement due to cancers, congenital defects, or trauma, leading to significant psychological, social, and economic disadvantage. Prosthetics aim to reduce their suffering by restoring aesthetics and function using synthetic materials that mimic the characteristics of native tissue. In the 1900s, natural materials used for thousands of years in prosthetics were replaced by syntheti...

“…The eye would appear shrunken, deep seated with very low in terms of cosmetic value. 5 Long term leaving the eye anophthalmic without implant will result in surface loss and volume loss within the socket and become contracted 6 This makes it tough to fit prosthesis. Contraction of the socket can be classified, according to Gopal Krishna Classification: 7 Grade 0: Socket is lined with healthy conjunctiva and has deep and well-formed fornices.…”

Aim of this study is to access the improvement in psychosocial awareness and self-image of surgical anophthalmic patient after cosmetic rehabilitation with secondary implant followed by ocular prosthesis. Materials and Methods: It was conducted with 15 surgical anophthalmic patients who maintained a special and unnatural hair style to hide the facial deformity from others. These hair styles included growing long hair on a particular side of the head, covering part of the forehead and eyes. This makes other people curious and it does not look normal.Result: After reconstruction of the a anophthalmic socket by secondary ball implant along with scleral graft and followed by fitting of a well matching custom designed ocular prosthesis, the psychological condition, self-confidence of the patients were improved significantly. The follow up photographs of the same patient revealed that they no longer maintained the earlier special type of hair style. They looked confident in normal hair pattern. Conclusion:The study suggest that the psychological well being of those living with facial deformity due to eye loss is related to having a pessimistic outlook and the beliefs a patients has about their appearance and how accepted they feel by the society.
