In previous years, patients only had one basic option of IOL (intraocular lens) to be used during cataract surgery, called a standard IOL.  A standard IOL only allows for vision at one distance, meaning the patient would have to rely on glasses for reading following the removal of the cataract.  A standard IOL also does not correct any astigmatism (irregularities in the shape of the cornea) so while cataract surgery helps with blurriness that the cataract causes, it does not help with the astigmatic blurriness.  Advancements in the field of intraocular lenses have now given patients the choice of the type of IOL they want, giving them the power to decide how they want to see.  The subject of IOL selection is complex.  Here is brief list of what areas of vision specific intraocular lenses can help with:

 

Corrects

Does not Correct

Multifocal IOL NEAR, INTERMEDIATE,
DISTANCE VISION
ASTIGMATISM 
Toric IOL DISTANCE VISION, ASTIGMATISM NEAR, INTERMEDIATE VISION
Monofocal IOL
(standard IOL)
SINGLE FOCUSING AREA
(USUALLY JUST CHOSEN
FOR DISTANCE VISION)
NEAR, INTERMEDIATE VISION
ASTIGMATISM

Insurances do not cover these premium intraocular lenses as of yet, so patients choosing premium intraocular lenses will self-pay for these lenses.  In addition, not all patients are good candidates for premium intraocular lenses.  Patients needing cataract surgery will be given information on options and the pricing of premium intraocular lenses during their pre-op appointment.
