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.
Spermatocele is a fluid-filled cyst that develops at the top of the testicle of the epididymis. The fluid is usually a clear or milky white color and may contain sperm. Spermatoceles are typically filled with spermatozoa and they can vary in size from several millimeters to many centimeters. Small spermatoceles are relatively common, occurring in an estimated 30 percent of males. They are generally not painful. However, some people may experience discomfort such as a dull pain in the scrotum from larger spermatoceles. They are not cancerous, nor do they cause an increased risk of testicular cancer. Additionally, unlike varicoceles, they do not reduce fertility. History
"Spermatocele" is originally derived from the Greek term spermatos (sperm) and kele (cavity or mass). Oftentimes, "epididymal cyst" has been used interchangeably with "spermatocele." However, it is important to note their differences. Epididymal cysts may appear anywhere along or within the epididymis and do not contain sperm, whereas spermatoceles may contain sperm. Epididymal cysts have been shown to occur more frequently in children before reaching puberty. Epidemiology
Spermatoceles usually affect men who are middle-aged and can, although rarely, affect children during puberty. The incidence rate is around 5-20% for children. It is estimated that approximately 30 percent of men have been diagnosed with small spermatoceles while less have larger spermatoceles. The incidence of spermatoceles increases as men age. Before puberty, children from the male sex may develop a similar benign mass called epididymis cyst.
