Ther Adv Ophthalmol 2022; 14:25158414221106682. [PMID: 35782482 PMCID: PMC9247992 DOI: 10.1177/25158414221106682] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2021] [Accepted: 05/24/2022] [Indexed: 11/16/2022] Open
Abstract
Three-dimensional (3D) printing uses a process of adding material in a layer-by-layer fashion to form the end product. This technology is advancing rapidly and is being increasingly utilized in the medical field as it becomes more accessible and cost-effective. It has an increasingly important role in ophthalmology and eyecare as its current and potential applications are extensive and slowly evolving. Three-dimensional printing represents an important method of manufacturing customized products such as orbital implants, ocular prostheses, ophthalmic models, surgical instruments, spectacles and other gadgets. Surgical planning, simulation, training and teaching have all benefitted from this technology. Advances in bioprinting seem to be the future direction of 3D printing with possibilities of printing out viable ocular tissues such as corneas and retinas in the future. It is expected that more ophthalmologists and other clinicians will use this technology in the near future.

Abstract
Three-dimensional printing enables precise modeling of anatomical structures and has been employed in a broad range of applications across medicine. Its earliest use in eye care included orbital models for training and surgical planning, which have subsequently enabled the design of custom-fit prostheses in oculoplastic surgery. It has evolved to include the production of surgical instruments, diagnostic tools, spectacles, and devices for delivery of drug and radiation therapy. During the COVID-19 pandemic, increased demand for personal protective equipment and supply chain shortages inspired many institutions to 3D-print their own eye protection. Cataract surgery, the most common procedure performed worldwide, may someday make use of custom-printed intraocular lenses. Perhaps its most alluring potential resides in the possibility of printing tissues at a cellular level to address unmet needs in the world of corneal and retinal diseases. Early models toward this end have shown promise for engineering tissues which, while not quite ready for transplantation, can serve as a useful model for in vitro disease and therapeutic research. As more institutions incorporate in-house or outsourced 3D printing for research models and clinical care, ethical and regulatory concerns will become a greater consideration. This report highlights the uses of 3D printing in eye care by subspecialty and clinical modality, with an aim to provide a useful entry point for anyone seeking to engage with the technology in their area of interest.

Abstract
Additive Manufacturing (AM) capabilities in terms of product customization, manufacture of complex shape, minimal time, and low volume production those are very well suited for medical implants and biological models. AM technology permits the fabrication of physical object based on the 3D CAD model through layer by layer manufacturing method. AM use Magnetic Resonance Image (MRI), Computed Tomography (CT), and 3D scanning images and these data are converted into surface tessellation language (STL) file for fabrication. The applications of AM in ophthalmology includes diagnosis and treatment planning, customized prosthesis, implants, surgical practice/simulation, pre-operative surgical planning, fabrication of assistive tools, surgical tools, and instruments. In this article, development of AM technology in ophthalmology and its potential applications is reviewed. The aim of this study is nurturing an awareness of the engineers and ophthalmologists to enhance the ophthalmic devices and instruments. Here some of the 3D printed case examples of functional prototype and concept prototypes are carried out to understand the capabilities of this technology. This research paper explores the possibility of AM technology that can be successfully executed in the ophthalmology field for developing innovative products. This novel technique is used toward improving the quality of treatment and surgical skills by customization and pre-operative treatment planning which are more promising factors.

Abstract
Since its conception in the 1980's, several advances in the field of additive manufacturing have led to exploration of alternate as well as combination biomaterials. These progresses have directed the use of 3D printing in wider applications such as printing of dermal layers, cartilage, bone defects, and surgical implants. Furthermore, the incorporation of live and functional cells with or atop biomaterials has laid the foundation for its use in tissue engineering. The purpose of this review is to summarize the advances in 3D printing and bioprinting of several types of tissues such as skin, cartilage, bones, and cardiac valves. This review will address the current 3D technologies used in tissue construction and study the biomaterials being investigated. There are several requirements that need to be addressed, in order to reconstruct functional tissue such as mechanical strength, porosity of the replicate and cellular incorporation. Researchers have focused their studies to answer questions regarding these requirements.

Low-cost three-dimensional printed orbital template-assisted patient-specific implants for the correction of spherical orbital implant migration. Indian J Ophthalmol 2018; 66:1600-1607. [PMID: 30355870 PMCID: PMC6213664 DOI: 10.4103/ijo.ijo_472_18] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2018] [Accepted: 07/13/2018] [Indexed: 11/24/2022] Open
Abstract
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.
