[Cataract surgery after refractive surgery: Part II: the problem of implant calculation]

Refractive surgery is a growing technique in a selected population of young patients who no longer want to wear corrective lenses. As this population becomes older and reaches an age where cataracts may develop, we decided to examine the problems encountered in calculating the IOL. Certain techniques may perturb keratometry oe measurement of axis length, two elements essential for calculating the implant. In certain cases where no solution is currently available for making these measurements, we propose archiving keratometry and axial length measurements for candidates for refractive surgery.
