Am I really seeing 20/20?

Postby carmen123 » Wed Jun 13, 2007 1:30 pm

Hello!

I'm back again. Hard to believe it's been almost a year since my first LASEK treatment!

Before Treatment Vision: -9/9.5 both eyes

Approximately one month ago, I had my left eye enhanced (LASEK). It had regressed to about a -2.

The results so far have been great! I'm seeing 20/20 from my left eye and the starburts in low lighting have dramatically decreased! At night, I still experience starbursts, but they aren't quite as bad as before.

Now, however, I have concerns over my right eye. My doctor says I am seeing 20/20 in my right eye. While it is true that I can just barely make out the 20/20 line on the charts, indoors there is no clarity. There is a noticeable difference between my left and right eye once again and it is frustrating.

If my right eye was seeing as well as my left, I know that my indoor vision would be great, but as it is, I still see shadows around everything unless I cover my right eye.

So here is my question - is there anything that can be done for a person who is seeing "20/20" but having problems in low lighting? Alphagan may be an option, but like many people have noticed, it isn't really a permanent solution as its effects wear off over time.

Can any sort of treatment be done, or is this too risky? Could a contact help? What are my options??

Thank you so much!!

LASEK - Was that surface abalation vs lifting your flap?
If so, was it because your corneas were to thin for a flap lift/enhancement doing lasik?
I hear you the not crisp/clear 20/20 or 20/30.

The first and second procedure were LASEK which is a surface ablation. It's essentially PRK. So she had no flap to lift when it came to doing an enhancement.

It's a smart move going LASEK instead of Lasik and having the flap. Wish I had gone that route.

The Snellen 20/whatever visual acuity test may be the standard for over a century, but it most assuredly has its limitations. A contrast sensitivity test may be more appropriate.

The root cause of the problem needs to be determined before anyone can recommend a potential treatment. If it is simple refractive error then glasses, contact lenses, or enhancement surgery may all resolve the problem. If it is a rough ablated surface, then specialized laser treatment my help. If it is a problem with the outer edges of the cornea having a different refractive error than the center, then Rigid Gas Permeable (RGP) contact lenses or enhancement surgery may be helpful. If it is due to dry eye, there is a long list of potential treatments for LASEK induced dry eye. There may be many options available, but which option is appropriate will not be known until you have an accurate diagnosis.

If your current surgeon is unable to explain or resolve your problem, it is time for a second opinion. I recommend you consider a corneal specialist at a university affiliated teaching hospital.

Thank you very much for responding.

I've never heard of a contrast sensitivity test. What does this test involve?

How could my doctor determine if I have a rough abalated surface? Is there a test for this also?

I have a feeling that my problem is due to a very slight myopia and a difference between the refractive error in the outer edges of the cornea. If this is the case, could an enhancement be done just to enlarge my treatment zone or is this too risky?

There are a couple of versions, but all relate to being able to decipher parallel black lines on a white background. The closer the lines are to each other, the greater the contrast sensitivity required to be able to see them as individual lines and not a grey blob. You may want to visit VectorVision.

Direct observation of the corneal surface.

This is the most simple and probably most likely cause.

It may be possible, but much depends upon the exact nature of the problem. A second opinon would be highly recommended before additional surgery.
