Dear cda,

Subject: The power of the lens of the eye.

The power of the eye's lens is about 10 diopters.

If that is removed, the total refractive power of the eye
is changed by that amount.

If the person had a refractive STATE of -5 diopters before
the removal of the lens (say for caterack), then the
eye's power would change to +5 diopters (by
simple optics.

The IOL is normally determined by calculation so
that when the lens is replaced, the eye's refractive
STATE is made approximately zero.

It is a great idea and it WORKS!

Best,

Otis

If a person were very nearsighted and then had his natural lens
removed, what sort of vision might he have? Could his eye structure
and cornea provide near "normal" distance correction? If not, why not?

So if I were +1.5 then I would be +11.5 and if I were -13.5 then I
would be -3.5 without any lens or IOL?
