A prosthetic eye, or ocular prosthesis, replaces the natural eye when it is absent from the socket. Usually it fits over an implant and underneath the eyelids to make it look as convincing as possible. People often refer to this type of prosthesis as glass eye, however these eyes can be constructed from a variety of different materials. There is also a variant which is actually a decorative shell and can be worn over a damaged eye to make it appear as if the eye is normal. It is important to understand that ocular prosthesis are not able to provide the individual with actual vision. However, there are visual prosthesis which are now able to assist individuals with this feat.
One factor that has bothered people for some time is that many of these types of prosthesis are not able to look realistic. For some people, it can be embarrassing to wear an ocular prosthesis when it looks too obviously unreal. As a result, there have been efforts for several decades to create an artificial eye which would look more realistic. The biggest issue has been the fact that the pupil in these styles have ultimately been immobile. More recently, there has been a breakthrough which may help to eventually remedy the issue. The artificial eye device is now able to simulate the pupil size by the use of ambient light. It was inspired by the general design of LCD screens.
In order for these types of prosthesis to be the most convincing, it usually requires the use of an implant within the eye area. The implants can be designated during a surgical procedure. Although the procedure is fairly complicated, there are many experienced doctors which have skill to handle the tasks without any concern. The individual who has received the surgery will have to wait for around 4 to 8 weeks before they will have their personalized prosthesis available for use. Sometimes, there is also an optional secondary surgery which allows individuals to place a peg or post within the implant area to ensure that the artificial eye is properly inserted and affixed during usage.
Ultimately, the use of the artificial eye has presented many benefits for individuals. It has allowed them to become more comfortable with interacting with society again and reduced the need to wear items like eye patches in the event that the eye has been injured or has required removal.
