Many patients who developed cataracts years after they had a cornea refractive procedure (LASIK, PRK, RK) have had successful cataract surgery and intraocular lens (IOL) implantation with good results. However, the required implant power is more challenging to predict because the modified corneal curvature cannot be accurately measured. Further, the optics of the combination (modified cornea with an IOL)  are generally not as optimal as a similar patient who develops a cataract years after ICL implantation. In the latter case, the ICL is easily removed, the original corneal curvature is preserved (never modified) and cataract surgery with an intraocular lens is implanted, yielding superior optical results.
