Question:
I just had a cataract remed on Dec 11. An intraoccular lens was installed.
It was sized to give me an overall +2 diopter eye before correction to be
fitted in January.
While riding as passenger in a car, I noticed multiple images of traffic
lights. By placing a stop, usually a finger, to block light at the periphery
of my pupil, some of these images could be made to disappear.
The effect is as if the lens had vertical striations or a grating in it so
that the images looked strung out horizontally. In some way, the effect is
similar to the fly's eye effect that was present with the cataract. While I
understand the optics of the situation, the medical aspects are not that
obvious to me.
My main question is: Will these aspheric characteristics improve by the time
I get fitted for corrective lenses? What is happening? To what extent can I
expect a cylindrical lens to correct the multiple images? How often does
such asphericity show up? What is the likelihood that the multiple images
actually are caused by defects in the intraocular lens? Is there a problem
with the corneal refraction?
Answer:
I take it you have these effects without glasses on. It is entirely
possible that the effect is due to the uncorrected +2.00 refractive error.
Also, you are only 3 days post op and it is normal for there to be some
corneal edema and mild eye inflammation this early, which could also cause
those effects. You will need to wait until you have finished your post op
healing and get proper glasses to know whether these effects will still be
present.
