Most Accurate Cataract Surgery (MACS)

Precision Surgery

What distinguishes Most Accurate Cataract Surgery (MACS) from basic cataract surgery is precision. A MACS surgeon uses your many eye measurements to carefully plan exactly where to make the incision for removing your original lens and where your replacement lens will be placed inside your eye.

For example, if you have an astigmatism that requires correction, the incision for your lens may be moved from the standard location to reduce your astigmatism with the replacement lens. Although time in surgery with the MACS procedure is not much longer, your pre-operative work in the clinic for eye measurements and testing will take a little longer than for basic cataract surgery. There also may be some additional time after the surgery to assess your vision rehabilitation and do some vision checks.

Otherwise, it is similar to a basic cataract operation, in that:
  • Each eye surgery is performed on a different day.
  • MACS is an outpatient procedure, so you will be able to go home the same day.
  • You will have a protective shield over your eyes after surgery, so you should plan to have someone else drive you home.
  • You will need to administer eye drops, prescribed by your surgeon.

This is a general overview of MACS surgery. Your MACS surgeon will discuss your specific surgical plan in detail prior to surgery, as well as any specific instructions for before and after surgery.
