What causes blurry vision and astigmatism after cataract surgery?

default
Posted on Mon, 1 Dec 2014 in Vision and Eye Disorders
Question: I have just completed cataract surgery in my left eye, a couple of weeks ago. My right eye turned out great! I can now legally drive, after suffering from acute myopia my entire life. I am 67years old, by the way.

The problem is my left eye. I can't see at distance, everything is blurry and can't see clear enough to read with reading glasses. Also everything appears smaller and further away with my left eye and when I look at vertical lines, there is a distortion of a bulge to the right of the line. I do have some astigmatism in my left eye and it is also more myopic than my right. But is this normal? If the problem is with the lens that was implanted .... can it be safely replaced?

Brief Answer:
It can be because of astigmatism or macular edema.

Detailed Answer:
Hello Sir,
Welcome to Health care magic.

I am Dr. DADAPEER K, an ophthalmologist and I answer health problems related to eye.

I reviewed your history. It seems from the history that you are having symptoms of objects appearing smaller and distortion of the vertical lines following cataract surgery.
These symptoms can be because of astigmatism either pre existing one or one induced by surgery. This can be found out by simple vision and refraction testing and it can be corrected by spectacles.
If there is no astigmatism it can be caused by cystoid macular edema which is one of the common complication of cataract surgery because of inflammation caused by surgery or by myopic degeneration of the macula which is seen in high myopia as in your case.
This can be found out by fundus examination by indirect ophthalmoscopy.

Hence you need to consult your ophthalmologist for refraction testing and fundoscopy to look for these things and correction if found.

Intraocular lens itself can be a source of astigmatism if it is tilted but this very rare. Hence replacing the intraocular lens is not required.
If required intraocular lens can be replaced by a procedure called as lens exchange. This is done very rarely because of complications associated with it like one more surgery and difficulty in removing the intraocular lens if surgery has been done long time back.

Hence I advice you not to worry, but to consult your ophthalmologist for examination to find out the underlying cause and treatment accordingly.
Do write back to me after the examination so that I can advice you more accurately.

Hope the information is helpful to you.
Thank you
