The second type of IOL, more commonly known as a phakic intraocular lens (PIOL), is a lens which is placed over the existing natural lens, and is used in refractive surgery to change the eye's optical power as a treatment for myopia, or nearsightedness.Most IOLs fitted today are fixed monofocal lenses matched to distance vision.With the latest advances, having clear vision at only one distance is no longer the only option.Presbyopic IOL technology can not only correct impaired distance vision, but also maintain the eye’s focusing power for reading and computer work.
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.
These are implanted during cataract surgery, after the cloudy eye's natural lens (colloquially called a cataract) has been removed.
The pseudophakic IOL provides the same light focusing function as the natural crystalline lens.
Several new intraocular lenses (IOLs), called multifocal and/or accommodating IOLs, have been introduced in recent years that utilize advanced technology to achieve good distance, intermediate and near vision without glasses.
One such lens is the Acry Sof® IQ Re STOR® lens, a breakthrough lens that uses apodized diffractive technology (similar to technology used in telescopes and microscopes) to give patients a full range of vision – near through distance – and to reduce dependency on reading glasses or bifocals following cataract surgery.
