Intraocular implants may be appropriate for some patients with cataracts or presbyopia. When you visit an optical center in Chicago to discuss having this type of eye surgery , the ophthalmologist will explain the different types of intraocular lenses (IOLs) that are available. One popular option is the monofocal lens, which is designed to provide optimal vision at near, intermediate, or far distances. If your monofocal lens is set for near distance, then you would need eye glasses to see at far distances. Another option is to set one lens for near and another for far distances. This is known as monovision and it provides vision at intermediate distances.
Alternatively, your ophthalmologist might recommend that you have multifocal or accommodative lenses. This is a newer type of IOLs that may reduce your dependence on glasses and contact lenses. A multifocal lens features a series of different focal zones, which can allow for both near and far distance vision.
