Clear Vision In Any Light
Traditional monofocal IOLs provide good vision (correcting nearsightedness or farsightedness), but do not correct for other optical imperfections including astigmatism, presbyopia, or spherical aberration. This is a type of optical imperfection that can cause increased glare, and reduced overall quality of vision in low light and darkness. Lenses that correct for spherical aberration are called aspheric lenses. If you notice any reduction in night vision clarity before IOL care, this may be only partially corrected by standard monofocal IOLs. That's why most IOLs these days incorporate aspheric optics.
Aspheric IOLs are monofocal lenses that correct for spherical aberration. The result is a lens that will provide better overall vision than traditional IOLs, especially at night.
Patients who choose an aspheric IOL can expect:
- Improved contrast sensitivity
- Enhanced functional vision
- Superior night driving ability
There are several acceptable options for the preferred vision target after IOL care. Some people will be happier having both eyes corrected for optimum distance vision. This affords the best balance between the two eyes, and the best depth perception. Others will prefer having one eye adjusted for optimum distance viewing and the other eye adjusted for intermediate or near range viewing. This is referred to as monovision.
With full binocular distance vision, you can expect to have dramatically enhanced distance vision with spectacular clarity and improved visibility in low light. This option will not correct for presbyopia so you will still need to wear readers to view things at close range.
