Do measurments change?????? Really confused!!!

This forum really needs an edit button!!!

Hi Soks, those images that I uploaded are all from Dr Zeiss visit.

Please go with Zeiss 26D in right and 25.5D in left.

Q1- So roughly a difference of 1.5D. What will the actual targeted values be in each eye post OP? Remember Dr Zeiss suggested -0.2 in Right and -1.4 in left.

I assume you are getting your suggestion from the sheet below.

Q2- Is that sheat showing targets based on the IOL used? So No. 2 in blue must be Zeiss tri839mp Lisa Trifocal? No.1 must be ZEISS CT ASPHINA .

No. 3 I don't know and No.4 seems like some unknow IOL from Ophtec that I have never heard of.

so for lisa for right eye 24.5D iol will require her to get glasses for -0.9D, almost -1.0D for distance. for lisa left eye 25D iol will require her to wear glasses for -0.79D, almost -0.75D for distance. i think those are good selections with a monofocal. please note they ate using the haigis method but the best method is barrett 2 for iol calculations.

for ct asphina right 24D iol will give you -0.62D, meaning she will need -0.5D glasses in that eye for distance. they dont make -0.6D glasses. for left ct asphina go with 24.5D diopter iol. this will require her -1.25D glasses for distance. so the difference between 2 eyes will be (-1.25-(-0.62)) = -0.63D. this will be great mini monovision. please note that how much near she will get is difficult to predict. they are using haigis but barrett 2 is latest and greatest. there could be -0.25 error in measurements especially in the cataract eye and post surgery when the iol settles.

"Please go with Zeiss 26D in right and 25.5D in left." - this was for the zeiss onatario lens. rational was that both eyes would need about -0.75 glasses for distance.

Am I reading correct that her current values are

Right

Spherical + 1.25

Cylinderical -0.50

Axis 112

Left

Spherical +1

Cylinderical -1.00

Axis 139

u r reading correctly. those ate autorefractor (machine) values where you see a house or a parachute and it becomes clear. those readings are a bit exaggerated than what the optometrists gets by trial and error. it seems she is far sighted with more astigmatism in left eye than right. do the glasses clear her blurred vision?

do the glasses clear her blurred vision?

She has not worn any glasses ever but 4 days ago she got cheap +1.5 reading glasses and it allows her to work. Text etc looks bigger and slightly sharp but not true sharp.

I think the cataract prevents that maybe?

i think you should ask them about the 6.26mm pupil size. dysphotopsia has been the most irritating aspect of this whole ordeal for me.

I will ask, but what can they do about it anyway? Most respectable IOLs are 6mm and not larger.

What was/is your Pupil size?

i don't know what my pupil size is. it is not on any of my reports. i will check again. janus had mentioned a new 7mm iol. ASPIRA-aXA (by HumanOptics). I would have gotten that. It is a monofocal so would be difficult for those wanting edof/multifocal.

ASPIRA-aXA (by HumanOptics), German company next door to where I live. I don't know much about them plus finding a surgeon to place it!

Then how reliable is this company! I don't know why big names don't make a 7mm IOL as it makes so much sense!!!!

I believe the other manufacturers makes 6mm iols because it is very rare that bigger are needed, but off course it is a big problem for the few where it is a problem.

Here in Denmark many people get clear lens exchange because of presbyopia, many are in their forties getting trifocals as clear lens exchange, all trifocals are 6mm and works great for the large majority.

When my pupils were dilated by the drops I also had dysphotopsia because the pupil were too big.

But after the drops were out of the system I have had no problems at all, so I don´t think you should be worried about the pupil size under influence of eye drops, I don´t think it shows how the pupil reacts in natural state.

that measure of pupil size might be her mesopic or scotopic pupil size in the doctor's office before drops. the dilated size of her pupil should be larger than 6.26 mm

Wife is almost confident that the pupil size measurements were done after the drops. It was done is a pitch black room.

in that case she should not have a problem. you should see her pupil size at night. my 4 year old has huge pupils at night. 8mm+. so i would think they would have iol implants for children.

Actually I just measured my wife's eye with a ruler. Her iris is around 1.2cm so maybe my wife's pupil could hit 8mm too!!!!

Dr Zeiss did mention that my wife has large pupil and that she is young woman (women have a wider pupil diameter than men).

it does say that her iris is 12.11 and 12.06mm on her report. they call it WTW which stands for white to white distance = iris diameter. i have always wondered if the zeiss plate haptic would actually help with the dysphotopsia from large pupil.

WTW, makes sense! In that case I am impressed by my ruler based eye measuring skills 😃

I think it might, atleast on 2 sides based on my non existent science skills 😃

I am assuming the red edges are most problematic for positive dysphotopsia.

So Zeiss plate haptic has less of red area compared to C shaped haptic.

ur eye measuring skills are phenomenal. you should measure the pupil in the evening in low light. also i think my pupil is oval and the zeiss plates should be in a 2 and 8 o clock direction for me.
