Accommodating lenses for cataracts

Rated 4.74/5 based on 661 customer reviews

Intraocular lenses have been used since 1999 for correcting larger errors in near-sighted, far-sighted, and astigmatic eyes.

This type of IOL is also called phakic intraocular lens (PIOL), and the crystalline lens is not removed.

This procedure usually takes less than 30 minutes in the hands of an experienced ophthalmologist. After surgery, patients should avoid strenuous exercise or anything else that significantly increases blood pressure.

Phakic IOL appear to be less dangerous than excimer laser surgery in those with significant nearsightedness.

More commonly, aphakic IOLs (that is, not PIOLs) are implanted via clear lens extraction and replacement (CLEAR) surgery.

During cataract surgery, your physician will replace your natural lens with an IOL.

Today there are multiple types of IOLs, each delivering a different performance profile based on how the lens is designed.
