The aim of an accurate intraocular lens power calculation is to provide an intraocular lens (IOL) that fits the specific needs and desires of the individual patient. The development of better instrumentation for measuring the eye's axial length (AL) and the use of more precise mathematical formulas to perform the appropriate calculations have significantly improved the accuracy with which the ...
A phakic IOL. An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness; a form of refractive surgery.

The intraocular lens power calculations for clear lens extraction is similar to calculations used for conventional cataract surgery. [ 8 ] Under topical anesthesia, through a 2.2 mm corneal incision, the lens nucleus and cortex are removed by irrigation and aspiration technique using a phaco machine. [ 9 ]
