Age 56, male in good health with moderate nearsightedness (-2.75) and astigmatism (+1.25 to +1.75). Reading is getting more challenging especially in poor lighting conditions. LASIK procedure will address nearsightedness but most likely require reading glasses post-op. Alternative procedure to remove optical lens and replace with a multifocal lens implant used to treat cataracts. How common is this procedure for non-cataract patients? How safe and effective is it? Any drawbacks or advantages?
