Intraocular Lenses (IOLs)
Intraocular lenses (IOLs) are artificial lenses that are implanted inside the eye to replace the natural lens. They are commonly used in cataract surgery to restore clear vision and improve visual acuity. IOLs are made of a variety of materials, including silicone and acrylic, and come in a range of shapes and designs to correct various visual problems such as nearsightedness, farsightedness, and astigmatism. They are designed to be permanent and do not need to be replaced. With advances in technology, IOLs have become a popular and effective option for restoring clear vision after cataract surgery.
During cataract surgical treatment, the Intraocular lens (IOL) replaces the natural lens in your eye to supply the function of focusing light onto the retina. IOLs are generally made from plastic and most of them are monofocal lenses to remedy range vision. With advances in technology, specialized IOLs have been and continue to be developed to improve the ease and success of cataract surgery and to enhance the patient’s vision. Now, from multifocal IOLs to IOLs that obstruct UV and blue light radiation, patients have greater alternatives offered to them.
Presbyopia Correcting IOLs– Multifocal or Accommodating IOLs
Presbyopia is another typical condition associated with aging, in which the eyes begin to have difficulty focusing on near things. This condition makes it difficult for people to read the fine print, which is why lots of people over 40 keep checking out glasses close by.
Comparable to bifocal or multifocal reading glasses, accommodating and multifocal IOLs provide vision correction for far and near (reading) vision to supply the client with clear sight at a series of distances without the need for reading glasses.
Although you may be able to do most activities without glasses, there may be circumstances that require a spectacles prescription to hone your vision.
Multifocal lenses contain numerous lens powers for various viewing distances while accommodating lenses have one lens power but accommodate or move with your eye as it concentrates on objects at a variety of distances.
Other Types of IOLs
IOLs that block out ultraviolet (UV) and blue light radiation, which have actually both been shown to be dangerous to your eyes, are also available.
Other premium IOLs exist such as aspheric IOLs which, similar to your real lens, are aspheric in shape and can enhance vision quality, especially in low light conditions, or toric IOLS which are appropriate for remedying astigmatism, nearsightedness, or farsightedness. Premium lenses such as these are more expensive than basic monofocal IOLs and might not be right for everyone.
Picking the best IOL for your eyes, way of life and vision is a choice that should be made together with a trusted optometrist.
For some people, it may even be a choice to place different IOLs in each eye.
