Is it possible to determine a deceased person's eye prescription?
Would an autorefractor work in this case?

Why??
At least you've garunteed that they won't be back for a remake :bbg:
holy death fetish, batman.
Are we talking about a zombie? If so I would be more concerned about them eating my brain.
From a forensics point of view, I would believe an autorefractor could determine a refraction, depending on the clarity of the aqueous and vitreous fluids. The result certainly would record an accurate astigmatic correction required, and axis position, which could determine an eyewear match to the deceased. I think an autorefractor requires the eye to be focussed at infinity, and any ciliary process disturbance would skew the accuracy of the amount of myopia, hyperopia. Presbyopic measurement would theoretically be impossible.
Interesting question!
I think there's an app for that.
Kind of related to this thread....
I always wondered how long a retinal scan (for indentification purposes) is good after death. Law and Order SVU had a body fished out of the Hudson identified by the retinal scan, and the beginning of the book "angels and demons" had an eye excised from a murder victim and used in a security scanner.

Thats an interesting consideration. At least immediately following death I'd expect the ciliary muscles to relax, à la bladder and bowels. :drop:Originally Posted by uncut
I still want to know 'why' someone wants to know this. Is there a medical or forensic reason??
Ok, I will give you this one. If you are deceased, you can buy your glasses online.
Here's one example of a reason "Why?"

I would suggest waiting until after the rigor mortis has passed.
Just wondering because my doctor is a huge CSI fan, and this could make an interesting episode.
My doctor she doesn't know the answer.
Sounds like it is not possible?
Just get the last RX..................that will do
One thing is certain...the need for an accommodative add power is not required.

Ah, but Chris, would the process of passing away have major effects on vision?
An autorefractor works like retinascopy by measuring the reflex when light is shinned across the eye and then trying to neutralize the reflex with lenses. Unless I am mistaken It has been a while since I read up on it. If a person is dead I doubt you would get a reflex reaction.
Well, if you were to make a 3d model of a person's eye (most likely CGI), could you (roughly) determine refracive error from the shape? I wouldn't want to try for an exact Rx, but I would think that you should at least know if the person would need plus/minus correction, and at least a range (i.e., -3.00 to -5.00, etc.) For add in a presbyope, I would think that, if done quickly enough after death, examination of the elastisity remaining in the crystaline lens (provided they still had it) would be a guide.
There are rules. Knowing those are easy. There are exceptions to the rules. Knowing those are easy. Knowing when to use them is slightly less easy. There are exceptions to the exceptions. Knowing those is a little more tricky, and know when to use those is even more so. Our industry is FULL of all of the above.

I thought irises were scanned, not retinas. That's what they scanned when I worked at a CC call center.
Yes you can (do you even need a license?). My doc says he used to practice static refractions on excised cows eyes.
