A lot of patients ask us about the differences between LASIK surgery and Multifocal Implants.  LASIK uses a laser to gently reshape the front of the eye to correct a patient’s refractive error.  If the patient is properly screened, LASIK will likely fully correct a distance vision problem.  However, the over-forty crowd in bifocals will still need reading glasses the rest of their life – unless they have it set up in monovision (one eye distance, one reading).  Multifocal implants (Crystallens, ReSTOR, etc.) came along with the idea of correcting both distance and near vision, so that patients rarely if ever need correction for any visual task, close or far away.  The procedure itself is basically cataract surgery, which has been proven safe and effective over many years.  It’s the implant design that’s new.

This will give you a good idea of the main differences:
LASIK – Pros     

  • Proven procedure
  • Less expensive
  • Fast recovery   
  • Very accurate

LASIK – Cons

  • If over forty, will still need readers
  • Thin corneas not a candidate
  • Dry eye sufferer’s symptoms may worsen
  • Very high corrections may not be candidates


  • 90% chance free of glasses                         
  • Thin corneas no problem                             
  • Dry eye problems less of an issue            
  • Even high corrections are candidates     
  • Patient will never have cataracts


  • Less proven than LASIK (newer technology)
  • More expensive (double or more)
  • Activity more restricted for 2 weeks post-surgery
  • May occasionally still need readers for fine print
  • Many users experience halos at night
  • More invasive thus greater risk complications
