These include intraocular lens prostheses, hemodialysis (linked to hepatitis, bacteremia, and shunt site infections), cerebrospinal fluid shunts (linked to ventriculitis, bacteremia, and local subcutaneous infection), orthopedic prostheses (linked to joint or bone infections), artificial heart valves (linked to endocarditis), vascular prostheses (linked to graft infection and bacteremia), and prosthetic heart valves (associated with endophthalmitis).

Because hospital-to-hospital variation in utilization makes it impossible to extrapolate expected nationwide usage patterns from data recorded from a few institutions, it is unclear how many illnesses are linked to these devices. A significant cause of morbidity and mortality in hospitalized patients is device-related infections. More descriptive research should be done in order concisely identify the incidence and prevalence of these infections. Despite the currently advised control methods, device-related infections have persisted, which suggests that each prospective preventative approach needs to be thoroughly evaluated to determine its genuine usefulness. These research projects must follow a case-control design. Multicenter trials may be preferable in some circumstances to gather a sufficient number of infected individuals. It is important to conduct more research on the pathogenesis of these illnesses to determine whether present preventive strategies are being applied correctly. Finally, different methods for applying control measures should be researched, as well as the degree of compliance with advised preventive measures in busy hospitals.
While some investigations reported on persistent issues with an ocular prosthesis, they could not determine what caused them. Literature, for instance,differed on how long a prosthetic eye should be worn before being cleaned and how this relates to any later infection or excessive discharge from the eye's socket. In addition, there is no widespread consensus on the specific cleaning, handling, and maintenance requirements for prosthetic eyes. On a different but related note, there is insufficient evidence that patients are involved in their treatment outcomes; as a result, important decisions about the most appropriate treatments and the care of specific patients are frequently based on clinicians' intuitive assessments of patient preference. Since the traditional plastic prosthesis has always had a solid mass, it has provided a weight issue that could prevent full orbital volume replacement. Currently being produced is a hollow plastic prosthesis that enables the technician to replace volume without worrying about damaging the cavity, which was previously technically impossible.
A cosmetic lens is applied to the patient with a blind eye or phthisical globe. Usually, a local anesthetic is applied to the native eye that will be covered in order to do this. In the palpebral fissure that surrounds the entire globe, an imprint tray is inserted. The casting shell is punctured with a syringe to insert a suitable alginate or impression cream. A stone cast is created once the impression cream has been withdrawn from the globe and gelled. A clear lens is created from this cast, which is a replica of the eyeball. The necessary modifications are made to the posterior surface of the lens and it is fitted to the patient's eye. The patient has an adjustment phase during which he develops a tolerance for the lens in this form of fitting. The cosmetic lens is finished with iris coloring and scleral tone once the patient can tolerate his trial lens for about eight hours each day. This method regularly produces the best all-around cosmetics.
