HealthWACH: What's your vision IQ?



If you or someone you know has ever worn a pair of prescription eyeglasses, then chances are that they have a pair of contact lenses as well. Contacts are a common form of treatment to those who struggle with vision loss and they provide sight to individuals who are unable to see at 20/20 vision. Most lenses correct astigmatism, nearsightedness, farsightedness, and presbyopia and are also used for patients who have undergone cataract surgery.

Laser in-situ keratomileusis (LASIK) is a laser vision correction surgery that reshapes the cornea to provide the patient with corrected vision without the use of contact lenses or glasses. This procedure has a 90% success rate and is said to correct vision immediately or by the next day. With little to zero recovery time needed, it is evident why most people who are in need of contacts and glasses turn to LASIK eye surgery.

This new advancement in eye correction offers a different route than LASIK eye surgery. Implantable contact lenses use to be a procedure that primarily targeted patients with cataracts, but now, it is available to those in need of vision correction. Similar to LASIK surgery, this operation surgically opens the cornea to adjust the focus of the eye. There are two different makes of implantable contact lenses to suit the individual; verisyse phakic intraocular lens (IOL) and visian implantable collamer lens (ICL). The IOL lens is made of plastic and is performed on patients ages 21 and older who have a change in refraction of less than 0.5 diopters in six months. The ICL lens is targeted for patients aged 21 to 45 with a change in refraction of less than 0.5 diopters in one year.
