“…Peyman GA et al [ 6 ] divided eye removal surgical techniques into three groups: the removal of the globe's contents while keeping the sclera, extraocular muscles, and optic nerve intact is known as Evisceration. When the muscles and optic nerve are severed, the globe is removed completely, a process known as Enucleation and Exenteration that involves removing all tissues from the orbit and the socket, including the globe, conjunctiva, orbital fat, and all or part of the eyelids [ 7 , 8 ]. An ocular prosthesis is fabricated for the first two surgeries, and an orbital prosthesis is given for the third [ 7 ].…”

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.

“…Numerous authors have extensively used polymethyl methacrylate (PMMA)-based ocular prostheses [ 7 ]. The incorporation of porcelain sclera veneer has also been suggested, which is costly and time-consuming [ 9 ]. Medical-grade silicone has been suggested because of its flexibility and reduced weight compared to acrylic [ 10 ].…”

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.

“…Fabrication of the lifelike appearance of the ocular prosthesis is important for the patient’s esthetics and comfort [ 17 ]. New materials and better fitting ocular prostheses allow patients to wear prostheses with greater comfort and better appearance [ 17 , 18 , 19 , 20 ]. In this study, iris fabrication is done from black paper and attached directly over the ocular prosthesis.…”

The study on the magnification of the clear acrylic resin in prosthetic dentistry is important but lacking. Hence, this research aimed to investigate the magnification of the iris in the ocular prosthesis with various thicknesses of clear heat cure acrylic resin. A total of 60 ocular prostheses were divided into six groups with various thicknesses of clear heat cure acrylic resin over the iris; T0 (control): no acrylic resin, T1: 2, T2: 4, T3: 6, T4: 8, and T5: 10 mm of clear acrylic resin over the iris. Each ocular prosthesis was manufactured from white acrylic, with a 10.250 mm iris. Then, the clear heat cure resin was placed over the iris, cured, then polished. The final diameter of the iris was measured with a vernier caliper. The sizes of the iris were compared among various groups using one-way ANOVA, and a significant level was chosen at p value = 0.01. The mean sizes of iris were T0 = 10.25, T1 = 10.92, T2 = 11.26, T3 = 11.91, T4 = 12.75, and T5 = 13.43 mm. The size of the iris was significantly different among the group (p < 0.0001). The magnification of the iris for different groups was 1.06 for T1, 1.10 for T2, 1.16 for T3, 1.24 for T4, and 1.31 for T5. The magnification of the iris increased as the thickness of clear heat cure acrylic resin over the iris is increased on the ocular prosthesis.
