LASIK and IOLs
AUG 17, 2015
I had LASIK surgery about 20 years ago and now need cataract surgery. Because of the LASIK procedure my surgeon recommends only monofocal lenses. Why is that?
Determining precise corneal shape helps your surgeon arrive at an accurate intraocular lens power (IOL) calculation. The shape of the cornea is permanently changed by LASIK. These changes make the accurate IOL calculations less dependable. Multifocal IOLs require very accurate measurements and calculations that cannot be reliably done after LASIK. Some ophthalmologists might try to comply with your request for a multifocal IOL post LASIK, but the risk is that your vision might be permanently blurry or require an additional surgery, which may or may not be covered by your insurance plan. Please see your ophthalmologist to discuss these options more fully.
