They should also visit their ophthalmologists regularly for several months so as to monitor the implants.

IOL implantation carries several risks associated with eye surgeries, such as infection, loosening of the lens, lens rotation, inflammation and night time halos, but a systematic review of studies has determined that the procedure is safer than conventional laser eye treatment.

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.CLEAR has a 90% success rate (risks include wound leakage, infection, inflammation, and astigmatism).CLEAR can only be performed on patients ages 40 and older.Again, these lenses can rotate inside the eye postoperatively, or be placed incorrectly by the operating surgeon.

Either way, the patient's preexisting astigmatism may not be corrected completely or may even increase.

First, they are an alternative to LASIK, a form of eye surgery that does not work for people with serious vision problems.

Effective IOL implants also entirely eliminate the need for glasses or contact lenses post-surgery for most patients.

Intraocular lens (IOL) is a lens implanted in the eye used to treat cataracts or myopia.

The most common type of IOL is the pseudophakic IOL.

This is to ensure that eye growth, which disrupts IOL lenses, will not occur post-surgery.
