Cataract Lens Replacement
Discover some interesting information and learn some helpful knowledge regarding what happens after cataract lens implants, as well. Keep reading to learn more about this fascinating surgery. This form of eye surgery is also referred to as cataract lens replacement surgery. Learn more about the actual cataract implant lens as well as more information about this corrective eye surgery by reading the following article.
Cataract surgery consists of removal of the cataract-affected intraocular (inner) lens and replacing the opaque, natural lens with a clear implant.
One of the most important decisions involved in this procedure is the type of replacement lens that will be used. These types include Premium Intraocular Lenses (or Premium IOL), Toric IOLs, Blue light-filtering IOLs, Aspheric IOLs, “Piggyback” IOLs, and Light Adjusting IOLs. In the following information, we will explain each of these options in further detail.
The traditional replacement lenses are monofocal, which means vision at one distance (either near, far, or intermediate). This type of lens is an improvement as opposed to the cataract-infected lens, however, reading glasses or contact lenses must be worn when performing activities that are not suited for the specific type of lens that has been chosen such as, reading, operating a computer, or viewing objects at arm’s length. However, the newest premium lens and accommodating lens implants are actually multifocal and allow exceptional clarity and focus regardless of the distance or the activity you are performing. Many times, Medicare or health insurance companies will not cover the cost of this type of lens because it is not deemed medically necessary.
Another option is the Toric IOLs, which help to correct astigmatism. This is considered a premium lens and will therefore cost more than traditional lenses. However, this type of lens is required if you have astigmatism. Some forms of the aspheric lenses are also available in options that filter out harmful UV rays or blue light. The risk for displacement of the lens resulting in poor vision is more likely with this type of lens.
If you will be replacing the lenses in both eyes, one of the best options available is Monovision. Monovision consists of near-sighted vision in one eye and distance vision in the other. This type of lens promotes better vision by adjusting to the needs of the patient. The depth of perception may be affected with this type of lens, as well. Those who have used monovision contact lenses might respond best to this type of lens.
The Piggyback approach refers to an additional implant on top of the original implant as a means of correcting vision, even further. This method is generally safer than removing the original lens implant. Blue Light-Filtering options have the ability to filter out the UV light and high-energy blue light, both of which may damage the eyes. Light-Adjustable options are available in some countries and can be changed after cataract lens surgery to make better vision correction after surgery.
