Hello, Welcome to Just Answer
Are you available for chat now?
How old is your neice now?
Do you have any idea about her vision in the right eye?
Is there any visible scar on the cornea?
what I know is that her doctor put in her eye something like a glass
it was to helper her to have a better sight
Does she wear glasses or contact lenses now?
I thinks she has a lense in her in the injured eye
she was also prescribe glasses to better her sight
but she did not see any improvement with the glasses. so she's not wearing them
are you there
Fine. In the given circumstances , I think that a needle prick to the cornea would more or less result in a faint scar more like a dot and would not hinder with the vision or be the cause of visual loss as such.
Moreover the needle would be sterile one thus rules out the possibility of any intraocular infection too.
see that happens seven years ago, now my question is why there's not improvement in her sight as her doctor said that would be
What needs to be done is to look out for any increase in her refractive error( short or long sightedness). By the way , when you said there is a lens in the eye, is it an intraocular lens?
furthermore. if she covers the left eye her sight is so blurred
yes it is an intraocular len
Just thought of the possibility that the needle prick could have been deeper damaging the lens. So the doctor would have removed the crystalline lens and inserted an intraocular lens. Since it was done at a very young age , there can be chances of development of an after cataract.
correct the doctor removed the cataract and them he placed the intraocular len
In after cataract there is thickening of the posterior capsule( thin membrane behind the lens) and is very common in children. It can be treated by an office procedure called Nd:YAG laser.
It is a safe laser procedure which removes the posterior capsular thickening.
that means that the lens would be removed to do that procedure
No the lens need not be removed.
so how is that procedure
If the vision has remained less from an after cataract, then following Nd:YAG laser there will be definite improvement.
so what is the probability of her recovering sight with the Yag laser
so what is the probability of recovering her sight
In this procedure the person is made to sit infront of a slit lamp and laser beam is aimed at the posterior capsule. It is a painless procedure and will hardly take a few minutes.
I understand the process, but what is the probability
are you there!
As I said earlier , first the cause of reduced vision needs to be established by a slit lamp exam. Once confirmed that it is due to after cataract then laser can be tried. Usually this procedure has a very high success rate ( only in rare cases the posterior capsule is very thick like a dense membrane which would then need surgical repair). Exact figures cannot be told though.
But overall Nd:YAG laser has very good success rate.
Visual improvement is seen the very next day itself.
The only thing to be noted is to rule out any other possible cause for reduced vision .
what is the other surgical repair?
Does this address your concern? Do you have any more questions ?
would you mind to explain me the surgical repair if the membrane is thinner
In case of thin membranes there is no need of any surgery and only laser will do.
Laser treatment is a non-surgical technique.
if there's a reduced vision, this could be fixed?
I'm to assume that her vision was good immediately after the initial surgery.
not it wasn't
that's why I am concerned
Oh I see. Any particular reason for the reduced vision post -operatively was given by the doctor?
If the vision was poor right after the initial surgery then there can be a number of causes for it and not after cataract.
in addition her dr. says to wait more time but has passed years and I didn't see any improvement in her vision. so I am thinking to see other specialist
what possible causes do you think could be? Like a bad the first surgery?
The list for post-operative complications of cataract surgery can be long and exhaustive. I would not be doing justice by simply naming all of them.
so do you think that has to do with the first cataract surgery? if so there's any solution for that
There could have been more internal injury to the eye by the initial needle prick itself( to the inner layers of the eye such as retina/macula). Also after the surgery there could have been inflammation of the eye( chronic uveitis), post-op astigmatism, macular edema, many if and buts.
I think it would be best to seek the opinion of another eye specialist who can have a look at the actual eye signs and then give further comment on the possible treatment modalities and prognosis.
in your opinion do you think there 's a good change of improving or recovering her vision if the retina.. was damaged
Since her vision never improved after the injury/cataract surgery, the cause of reduced vision has to be at that time itself. 7 years would be long time for any cause for reduced vision to improve. Whatever the cause is it needs to be detected by a thorough eye exam and then decided upon whether it can be treated or not.
If the retina is damaged , especially the central part called macula, then I'm afraid the visual recovery is going to be very poor.

Is there anything I can answer for you in this regard?
