The term phakic means lens. Phakic IOL means that you still have your natural lens (nothing has been removed) and a very thin phakic IOL has been added to correct the power. This differs from cataract surgery where your natural lens is removed before an intraocular implant is placed.
Posterior chamber phakic IOL and its manufacturing process
The present invention relates to a posterior chamber phakic IOL (1) having an inherent arch height (89A) independent of its external diameter (81), and a method for manufacturing such an IOL (1).

Methods for customizing intraocular lens using an optical aberrometer
Method steps for correcting vision in an eye that uses a customized phakic IOL composing: (1) measuring one or more wavefront aberrations of the eye: (2) designing a wavefront-customized correction profile for an Intraocular Lens (IOL); (3) creating a customized IOL with the customized correction profile; and (4) implanting the customized IOL in the eye. Alternatively, an uncorrected IOL is first implanted and aligned in the eye, followed by in-situ scanning a femtosecond laser spot across the implanted IOL to locally change the Index of Refraction of the IOL material and create an in-situ customized IOL.
