For me, the most exciting aspect of refractive surgery is improving the quality of like for my patients.  I take pride in giving my patients the miracle of sight without the dependence of glasses or contacts.  I look forward to seeing my patient post-operatively and sharing in their excitement over their newfound vision.  This is the most rewarding benefit of my profession.
