Frequently Asked ReZoom™ Questions


What eye conditions can be improved with ReZoom™ lenses?
Cataracts and presbyopia, both of which can appear as we get a bit older.

  • Cataracts are a clouding up of the natural lens, which make vision become increasingly dim and colorless. The natural lens is made up mostly of water and proteins. When the protein molecules start clumping together, they form tiny opaque areas in the otherwise clear lens, which diminish vision. There is no cure for cataracts, and the way to overcome this visual impairment is to replace the natural lens with an implantable lens such as ReZoom. Read more about cataracts
  • Presbyopia is that blurriness of near vision which sends us out to buy reading glasses after we hit the age of 40 or so. We can see OK in the distance, but the lens becomes increasingly unable to accommodate itself to near vision. It becomes stiffer as we age, and the muscles which control its curvature become weaker. But instead of wearing reading glasses, we can have a ReZoom intraocular lens implanted to replace the natural lens.


“Initially I was a little skeptical and scared but now I am extremely pleased with the improvement in vision. Thank you Dr. Khanna and Staff.”

Would I be able to throw my glasses away if I have ReZoom lenses?
Perhaps. Many people do, and some still use them occasionally. However, each of us is different in our exact eye conditions, and you would have to consult with an experienced eye surgeon like Dr. Khanna. If you are noticing blurriness with your near vision, your eyes would have to be very thoroughly examined and tested, your general health assessed, and an accurate diagnosis made as to your vision. Then Dr. Khanna would be able to recommend the best options. ReZoom lenses are very effective when appropriately used.

How does a ReZoom lens work?
It has five areas in it, optical zones, which distribute light differently. Clear vision depends on correct bending (refraction) of the light rays which enter our eyes, to make them focus on the retina, the “camera film” at the back of the eye. A ReZoom lens is able to bend light rays in five different ways, to give us a full spectrum of vision distances. It does not move with the eye, as some other implantable lenses do, but instead works with those five optical zones.

Can I go to any eye doctor to get ReZoom lenses?
No, you need to find an ophthalmologist who is trained in how to implant them. Before you choose one, ask lots of questions and make sure you get understandable answers. Ask how many times the doctor has implanted ReZoom lenses before. You should have only a very experienced eye surgeon, and one who will take time to make sure you understand the procedure and its risks, and have realistic expectations. The FDA approved ReZoom lenses only in 2005, so not all eye doctors are familiar with them.

What do ReZoom lenses cost?
That will depend on several factors. If you need them to treat cataracts, they are covered by Medicaid and Medicare and most health insurance plans. You might be asked to pay a certain portion of the total cost. If you need them to treat presbyopia, this will not be considered a medical necessity, as you could use glasses instead, and therefore they will not be covered by Medicaid or medicare, and probably not by most health insurance plans.

At Dr. Khanna’s office we can explain financial issues and work with you to find an affordable way for you to have ReZoom lenses.
