Ocular prosthesis incorporating IPS e-max press scleral veneer and a literature review on non-integrated ocular prosthesis

Advancements in the Ocular Prosthesis Technology: The Insightful Innovations

In patients who have lost their eye due to one or many of the following events, such as surgery, trauma, tumors, or birth eye defects, ocular prostheses play a very vital role in the recovery of their eye appearance and social appearance. This case report highlights the successful fitting and fabrication of a custom-made ocular prosthesis in a patient with an eye defect. The manufacturing process of the prostheses involved careful evaluation and fabrication involving a series of steps to achieve a successful prosthesis. A customized prosthesis guarantees excellent esthetic matching, more comfort, and increased patient confidence, thereby a better quality of life.

A Case Report on Iris Disk Positioning on a Custom-Made Ocular Prosthesis Using an Adjustable Trial Frame

Trauma, cancer, and congenital defects may all result in the loss of an eye. This leads to significant emotional and physical challenges in an individual's life. In such cases, cautious preoperative, surgical, and prosthetic planning employing a multidisciplinary approach is essential for effective rehabilitation. Iris positioning is one of the crucial steps in the fabrication of a customized ocular prosthesis. Iris positioning is a technique-sensitive process, hence visual evaluation by itself could not provide reliable results. This case report illustrates a method of iris disk positioning on a custom-made ocular prosthesis using an adjustable trial frame. The advantage of the adjustable mechanism of the adjustable trial frame was utilized here to position the iris on the scleral blank. Since the iris disk on the ocular prosthesis was positioned in symmetry with that of the natural eye, the patient's aesthetics were restored.

Automatic data-driven design and 3D printing of custom ocular prostheses

Millions of people require custom ocular prostheses due to eye loss or congenital defects. The current fully manual manufacturing processes used by highly skilled ocularists are time-consuming with varying quality. Additive manufacturing technology has the potential to simplify the manufacture of ocular prosthetics, but existing approaches just replace to various degrees craftsmanship by manual digital design and still require substantial expertise and time. Here we present an automatic digital end-to-end process for producing custom ocular prostheses that uses image data from an anterior segment optical coherence tomography device and considers both shape and appearance. Our approach uses a statistical shape model to predict, based on incomplete surface information of the eye socket, a best fitting prosthesis shape. We use a colour characterized image of the healthy fellow eye to determine and procedurally generate the prosthesis's appearance that matches the fellow eye. The prosthesis is manufactured using a multi-material full-colour 3D printer and postprocessed to satisfy regulatory compliance. We demonstrate the effectiveness of our approach by presenting results for 10 clinic patients who received a 3D printed prosthesis. Compared to a current manual process, our approach requires five times less labour of the ocularist and produces reproducible output.

Custom Ocular Prosthesis: A Case Report

Ocular prostheses play a vital role in restoring the appearance and functionality of the eye for individuals who have suffered from eye loss due to trauma, surgery, tumors, or congenital eye defects. This case report presents the successful fabrication and fitting of a custom-made ocular prosthesis for a patient with an eye defect. The process involved careful examination and digital imaging for the fabrication of prostheses. The custom prosthesis provided an excellent aesthetic match, improved comfort, and enhanced the patient's self-confidence, ultimately leading to an improved quality of life.

Osseointegrated Implants and Prosthetic Reconstruction Following Skull Base Surgery

Rehabilitation following ablative skull base surgery remains a challenging task, given the complexity of the anatomical region, despite the recent advances in reconstructive surgery. Remnant defects following resection of skull base tumors are often not amenable to primary closure. As such, numerous techniques have been described for reconstruction, including local rotational muscle flaps, pedicled flaps with skin paddle, or even free tissue transfer. However, not all patients are appropriate surgical candidates and therefore may instead benefit from nonsurgical options for functional and aesthetic restoration. Osseointegrated implants and biocompatible prostheses provide a viable alternative for such a patient population. The purpose of this review serves to highlight current options for prosthetic rehabilitation of skull base defects and describe their indications, advantages, and disadvantages.
