That Depends On The Option You Choose
Should you pay extra for cataract surgery? Many surgeons refer to these options as “Premium,” “Advanced,” “Custom” or “Refractive” cataract surgery.
First let me describe the three basic choices that are available today.
Option 1 - Basic cataract surgery
Basic surgery is what we have been doing for the last 30 years. The cataract is removed through a small incision in the eye, in almost all cases with the assistance of an instrument called a phacoemulsifier. This is an ultrasound-driven instrument that breaks the cataract into small pieces before it is then sucked out of the eye.
Once that is completed an intraocular lens is placed in the eye. This lens is called a fixed-focus lens, which means the lens allows you to see well in one place in space. Most of the time the lens is chosen for good distance vision (but it can be chosen for good near vision instead).
With this lens you see well at the distance chosen but can’t see...
When soft contact lenses first came on the scene, the ocular community went wild.
People no longer had to put up with the initial discomfort of hard lenses, and a more frequent replacement schedule surely meant better overall health for the eye, right?
In many cases this was so. The first soft lenses were made of a material called HEMA, a plastic-like polymer that made the lenses very soft and comfortable. The downside to this material was that it didn’t allow very much oxygen to the cornea (significantly less than the hard lenses), which bred a different line of health risks to the eye.
As contact lens companies tried to deal with these new issues, they started to create lenses that you not only replaced more frequently, but also the materials themselves changed from HEMA to SiHy, or silicone hydrogel. The oxygen transmission problem was solved, but an interesting new phenomenon occurred.
Because these were supposed to be the “healthiest” lenses ever created, many...
