Intraocular lens power adjustment nomogram after laser in situ keratomileusis

A 2nd-order polynomial relationship was found between LASIK-induced MRSE change and the MRSE error after cataract surgery. From this equation, a simple adjustment nomogram was generated and put into a look-up table format. The formula and nomogram should improve IOL power calculation accuracy in post-LASIK eyes when the MRSE change is known.
