Toric
A toric IOL is a type of toric lens used to correct preexisting corneal astigmatism at the time of cataract surgery. Astigmatism can also be treated with limbal relaxing incisions or an excimer laser procedure. About 40% of Americans have significant astigmatism and thus may be candidates for a toric IOL. Cataract surgery with implantation of a toric IOL is essentially the same as cataract surgery with a conventional IOL. Like toric contact lenses, toric IOLs have different powers in different meridians of the lens, and they must be positioned on the correct meridian to reverse the preexisting astigmatism. If the toric IOL is not on the correct meridian, it may need to be repositioned in a second procedure. Multifocal toric
Standard toric IOLs are monofocal, permanently focused on distant objects. Multifocal toric IOLs are also available. These lenses provide the patient not only with correction of preexisting astigmatism, but also with multiple-focused vision at far and reading distance

Phakic IOLs
Phakic IOLs (PIOLs) are intraocular lenses which are placed in an eye that still contains a natural human crystalline lens. PIOLs are sometimes referred to as an implantable contact lenses (ICLs). As with other IOLs, PIOLs can be either spheric or toric. Toric PIOLs have to be aligned with the meridian of astigmatism; toric IOL misalignment or rotation can lead to residual or even greater astigmatism postoperatively.Depending on their attachment site to the eye, PIOLs can be divided into three categories:
Angle-supported PIOLs, placed in the anterior chamber.
Some of the risks that FDA have been found so far during a three-year study of the Artisan are:

a yearly loss of 1.8% of the endothelial cells,
0.6% risk of retinal detachment,
0.6% risk of cataract (other studies have shown a risk of 0.5–1.0%), and
0.4% risk of corneal swelling.Other risks include:

0.03–0.05% eye infection risk, which in worst case can lead to blindness. (This risk exists in all eye surgery procedures and is not unique to IOLs.) glaucoma,
astigmatism,
remaining near or far sightedness,
rotation of the lens inside the eye one or two days after surgery.One of the causes of the risks above is that the lens can rotate inside the eye if the PIOL is too short, if the eye was incorrectly measured, or because the sulcus has a slightly oval shape (the height is slightly smaller than the width). Toric IOLs must be powered and aligned inside the eye on a meridian that corrects the patients preexisting astigmatism. Again, these lenses can rotate inside the eye postoperatively or be placed incorrectly by the operating surgeon. Either way, the patients preexisting astigmatism may not be corrected completely or may even increase. When standard IOLs are implanted with a CLEAR procedure, in substitution of the patients crystalline, astigmatism is typically not corrected, as astigmatism is mainly attributable to a deformation of the cornea. Toric IOLs may be used during the CLEAR procedure to correct astigmatism. The surgeon can ascertain the astigmatic, or steepest, meridian in a number of ways, including manifest refraction or corneal topography.
