By doing so, the lens can change its power in the eye, similar to the process of accommodation of the eye’s natural lens.
The remainder did require the additional help of reading glasses in order to see fine newsprint.
In contrast, the Crytstalens incorporates both distance and near capability into a single lens by its ability to change from distance to near power while inside the eye.
The Crystalens accomplishes this by use of two small hinges, which allow the lens to move forward and backward slightly inside the eye.
The main advantage offered by Crystalens over a traditional, monofocal lens implant is the opportunity to become less dependent on reading glasses for near activities.
Activities that were once easily enjoyed without glasses, such as reading or sewing, now require a pair of reading glasses always be available.
Your surgeon can help you decide which lens may be best for you.
Ever since their conception, multifocal intraocular lenses (IOLs) have been measured against their predecessor, monofocal lenses.As the power of the lens becomes stronger, its ability to bend light more sharply is increased.Since the lens is monofocal, the light can only be bent to one focus point at a time.The standard intraocular lens has no focusing capability, whereas an accommodating intraocular lens allows focusing on near and distant objects.C75.1 Insertion of prosthetic replacement for lens NEC Note: A supplementary OPCS-4 code is used to identify the method of concurrent extraction of lens (C71-C74) It is not possible to capture the type of lens using OPCS-4.This guidance represents the view of NICE, arrived at after careful consideration of the evidence available.
