Vision change after C3R
Permalink   
 


Hello everyone,

I have keratoconus in both eyes. i underwent C3R in my right eye on 21st december 2007.

Here are my pre-op readings on 15th Dec 2007-
Power 46.2D(7.30mm)
SimK Values 48.62D@154, 42.00D@64

Here are my post-op readings on 7th Feb 2008(7 weeks past operation) -
Power 47D(7.19mm)
SimK Values 49.37D@164, 42.25D@74
Power Diff : 0.8D
Curv Diff : -0.11mm

Pre-op glasses : -5.5/-1.0X70 degrees
Post-op glasses : - 5.5/-2.0X70 degrees

Prior to operation i used to get perfect vision with glasses. Now its 7 weeks past operation, i am not getting proper vision with my original glasses. They tried to test using various numbers, none of which were giving me a clear vision. There is haziness while reading the letters even with the new glasses.

It seems that my vision has deteriorated after the operation. Is this normal? Will this haziness go with time. If yes, how long it will take to get a clear vision.

Ruchika,

The Haze means that the treatment is working, it is entirely normal and well documented. Gradually it will go away, it can take mostly up to the last small amounts to go by 3 months or rarely longer. Full revovery is said to be around six months for the cornea to settle, Every other patient doing CXL gets some flatterning of there cornea, this can continue to happen even months after the recovery for some lucky people.

Welcome and thanks for joining in and posting

Dear Kane, Thanks for your reply. I read in the posts that usually the viison improves and SIMK values improve. In my case they have increased. Now i am a bit concerned regarding the treatment for my left eye. Should i wait for my right eye to stabalize or should i go ahead with the operation for left eye. Regards, Ruchika

Ruchika,

The K reading rise for around three months before they settle, it is part of the healing process, this was documented at the first Crosslinking congress, so don't worry about that. It is always prudent to do on eye at a time (unless its another treatment you have with crosslinking like two of our members had where specialised refractive vision correction was given at the same time which would correct the refractive errors more so as well - I am talking about the topics posted about limited Topo PRK done by a Dr who has the most experiance with this for KC), because you must be able to get around with fuctional vision in one eye at least until the treated eye recovers. So if there is no progression in the eye your thinking of treating, then there is no loss in waiting, in fact you will be gaining as you can go about your business more as usual by doing on eye at a time after useful vision has retured after the healing has taken place in the eye you have just treated.

Best wishes to you

Hello,

I wanted to add to Kane's words that the topographies you are making wright now are not accurate.The cornea because it has crosslinked has become more stiffen and this fools the topography machine at least at the first months.After a reasonable period you will see that your cornea will become more regular and moreover you will have better quality in your vision if the cones has flatten.

Collagen crosslinking takes it time my friend but you have done the best investment to your life by performing it because kc has freezed.Keep us posted and dont you worry coz with the days goes by you will notice the big difference and the vision to clear.

All the best,

Dear Kane & Zeus,

 

Thank you very much for your comments and encouraging words.

 

Can you tell me how to figure out whether my KC is progressing or not?

 

Secondly I could not make anything from the scans. How do we discover from scans that cone has flattened?

 

Regards, Ruchika

Progression can be checked with a corneal topography and checking thickness, the orbscan and pentacam can do both.

Check your K readings to see if things are flatter, but it will take much more time for that to happen ...and indeed if it happens but small amounts is a possibly.

hello to all the members:)

Its been 40 days since my left eye's crosslinking. Its my best eye. In frew days will have

the other one too. My dr is very good and he is there for all my questions. He performed an

epi-on crosslinkin. My vision was 8/10 before with just my glasses. Quite happy with that. At

this point my vision is worst. i see a doulbe image especially when driving at night..traffic lighs etc.

I read members stories and veteran members have always something good to say, thats a

big support.But left eye is the one that does all the job. My right is about 2/10.

This is the reason that am a bit worried. Dr sais it ll be ok, it takes some time, but i m not

quite sure about that...just a feeling..

Double vision is makining me so tired.. although for just few minutes now and then i can see

less of a double image but at night time its always there.
