-2.00 cylindrical eysight at 175 axis What it means ?

[vijaykrishna]

Just now i check up my eyes ..
Dr told me that i have -2.00 Cylindrical eye power at 175 AXIS for My left eye ..?
I am 25 years old . This is the first time i checkup my eyes . I am working as Software engineer.

My Question is What's the problem i had what that cylindrical eye sight means ? i am very new to this terminolgy could you explain me in  brief ?

Hopefully the eye "doctor" you saw was a MD ophthalmologist Eye MD. If not next time see a real physician.

-2.00 cylinder axis 175 indicates that the cornea (the part a contact lens fits on) is not round or spherical but aspheric or "astigmatic" in your case the cornea is curved more from top to bottom than side to side. Its not a disease.

Google "astigmatism" and it will show you a diagram of what it looks like.  That's not a lot. It causes some blurring of the vision. Adjusting to a glasses prescription with an astigmatic correction is sometimes difficult and if you can't wear the glasses comfortablly after 5-6 days go back to the "doctor" and have them check the glasses and re-evaluate the fit. (Our practice does not charge for  this type of service maybe yours won't either.  ASK)

I am not an eye care professional, so what I am about to say is based on what I remember from an optics course I had in college.

A spherical lens is one in which one surface of the lens is in the shape of the surface of a sphere. Imagine a slice taken off a sphere. The lens is thicker in the middle and thinner at the edges, and uniform all around.

A negative spherical lens can be formed by making a spherical impression in the surface of a flat piece of glass. It is thinner in the middle than at the edges. This is the kind of lens a nearsighted person needs.

A cylindrical lens has one surface in the shape of a cylinder. This kind of lens magnifies the image but only in one direction. You can make a cylindrical lens by filling a clear cylindrical glass with water. A glass of water will magnify images horizontally but not vertically. A negative cylindrical lens could be made by forming a hollow cylindrical impression in a flat piece of glass. That's the kind of lens you need to correct your astigmatism.

The axis refers to the angle the cylinder is tilted with respect to vertical, from 0 to 180 degrees. So your lens axis would have to be tilted 5 degrees. I don't know if it would be clockwise or counterclockwise. The number -2 is the measurement in diopters. Do a google search on diopter to see what that means.

my dr told me my right eye is -1 cyl and 10 degree axis and left eye is  -0.75 cyl and 180 degree axis. whats its mean.....???????

[John C Hagan III, MD, FACS, FAAO]

This means the eye is shaped like an American football lying on its side; the cornea is more curved vertically than horizontally.  Not a disease. Corrected with minus cylinder glasses axis horizontal or plus cylinder glasses vertial

wearing eye glasses for above case is mandatory.? if not any chances may increase the eye sight..

Given age 25  is optional but usually makes see better.

Hi John,

My daughter is 4 and half year old. She often rubbing her eyes and used to tell us seeming water is coming from eye but no water at all so took her hospital. Dr. prescribed as follows
Right Eye: SPH : NIL CYL: 2.50 AXIS: 10
Left Eye  : SPH: +0.75 CYL 2.50 AXIS: 175
He told us Cylindrical power only.

How can cure this problem, since she is very less age what can we do further. Is it curable with any food habits or exercise. Please help and suggest us.
Thanks in advance
Jaisankar.

[John C Hagan III, MD, FACS, FAAO]

The shape of the cornea is aspherical (astigmatic). Diet and expercises will not change the shape. Glasses are the preferred treatment till older when contacts may be helpful.

Consider a second opinion with an Eye MD ophthalmologist.

Thanks a lot Dr. for your great and valuable comment. Since she is 4 1/2 year old, she not able tell anything properly what happening. As per above prescriptions Is it big problem? If post-pone till her 6-7 year old, Is it increase / change the power?

Thanks,

It is possible to use instruments to determine if an infant or child needs glasses. it can be done without any response by the child. You should not postpone working through this problem as the eyes reach visual maturity at about 6-10 years of age and after that time reduced vision (refractive amblyopia) may not respond to glasses and patching.

How can cure this problem

[John C Hagan III, MD, FACS, FAAO]

That is a very weak prescription. Some people do fine without this type of RX, some wear just for specific tasks like driving at night or movies. Others chose to wear all the time.

There is no disease to 'cure'.

Dr. My yes test are: Right one is Sph +2 and Cyl -3 and Axic 10, the left one is Sph +0.75 and Cyl -2 and Axic is 165, is it dangers I`m really worried about and my doctor told me there is no need to do lasek but I cant see well without glasses. also dose the computer affects it because I`m working on computer a lot. thanks

[JohnHaganMD]

Your profile says you are age 25. Most people with that much astigmatism do need glasses or contact lens. Astigmatism is not a disease it means your cornea is not spherical like a marble but oval like an American football.  Astigmatism is more difficult to treat with lasik than a spherical cornea.  So if you are happy with glasses or contact lens (toric contact lens) you need not have expensive lasik. If you wish to consider lasik as an alternative to glasses/contacts you would have to see a very experienced refractive surgeon with access to the newest and most sophisticated lasers.

thanks a lot sir .

Hi Doctor,

I have -0.5  cylindrical sight for left eye along with -1.5 sight and -1.5 sight for tight eye when i checked with doctor , when i checked my eyes in showroom he told me -1.5 spherical is enough for me, he given me spects with that power. Will there be any problem if i don't use cylindricl power.

Regards
Lalitha

No way to tell. You could have adjusting if added or you might not see as well if not added.

Hi doctor,

What happen if i use contact lenses that is 180 axis while i have 10 axis on my eye?
Thank you

[satispande]

Hi Doctor,
just i have a question if I wear the lens continusly will my eyes be restored to normal i.e 0 pwer?

I have right eyes lens -0.5 cylindrical with 180 axis and  left eyes has -0.25 cylindrical with 180 axis. My doctor said we will again check it after 6 months?

[harithaM]

Dear doctor,
My daughter is 5.5 years old and is detected with astigmatim in both eyes and also has myopia , amblyopia in left eye.
The prescribed glasses that she started to wear is as below:

Right eye : sph: +0.00, Cyl: -00.75, Axis:170, V/A:6/7.5
Left eye: sph:-02.25, Cyl:-01.5, Axis:160, V/A:6/12

I am panicky, depressed, and do not know if she could ever get a normal vision minus the amblyopia, myopia an astigmatism...
Request your expert opinion on this..
Thanks much

from past two year i am using glasses . my left eye is -2.0 Axis 170
and right 1.0

in my lest eye when i look at far and i see the written words r double thats like a light shadow. what kind of problem is it??

[JohnHaganMD]

HarithaM:

1. Astigmatism is not a disease but amblyopia is. If you are just starting treatment your daughter is relatively old and amblyopia therapy is more difficult and less successful.
2. Therapy will usually start with glasses worn all the time; vision is rechecked if still down in left eye then a patch is often worn in the right eye to make her use the left eye more. Sometimes eye drops called atropine are used in the good eye to avoid the patch but make her use the LE more.
3. The goal of treatment is to improve the vision in the amblyopia eye to as good of a level as possible. The glasses will not make the myopia or astigmatism go away. When she's older contact lens or refractive surgery might help.
4. This problem runs in families so have all your children checked early (about age 3). Any children not have their eyes checked in last year should be examined. You should tell your brothers and sisters of this problem as nieces and nephews will be at higher risk also.

Shohan: That is not a question I can answer because there are too many possible causes. You will need to direct that question to the ophthalmologist or optometrist that checked your eyes
