A multifocal intraocular lens (IOL) focuses both distance and near images onto the retina at the same time. Amazingly, our retinas and brains are generally able to “see” both images clearly. This results in a greater range of clear vision with a reduced need for spectacles after cataract surgery. There are, however, some downsides to the multifocal IOL:
In theory the Crystalens® should provide a greater range of vision without the need for glasses compared to the Staar nanoFLEX®. However, I have not been impressed with the results of the Crystalens IOL.
The range of vision possible with cataract surgery using the Staar nanoFLEX® IOL is impressive, but not complete. It is often still necessary to wear readers to clearly see objects closer than arm’s length.
The Staar nanoFLEX® Intraocular Lens – my preferred IOL, is made from Collamer® which is “a pure collagen containing material that is “bio-compatible” with your body’s natural chemistry
During cataract surgery the natural lens of the eye is replaced with a clear synthetic lens. These “intraocular lenses” (or “IOLs”) come in a dizzying array of powers, shapes, and materials.
