Post Reply New Topic

well my eye sight is normal but i have very bad austigatisam eye.

well i heard u can do lence replacement and such.

can someone explain what u can do with bad eyes.

Surgery to replace the lens, no. But re-shape the cornea, yes.

I think you mean astigmatism. That's when the light does not focus to a single point at varying axis of rotation around the eye.

I had Lasik corrective surgery 6 years ago. My eyesight was -6 dioptres (sphere) and -1 cyl (astigmatism), and I needed glasses that looked like the bottom of a glass bottle.

One of the best things I did was to get my eyes sorted.
Took 10 minutes and I was out again. Completely pain free.

Go for it if you can,

<----- Looked into Lasik surgery but the opthamologist said his eyes were too elongatec and his vision was poor so he would still need glasses.

Lasik bothers me because it takes material away from your retina without adding any, in effect weakening one of the structures in my body I'm least interested in weakening. If they could find another way, I'd be more inclined to do it. Of course I'm also the kind of guy who uses hard maple and oak and 3 inch screws for all my woodworking.

Seeing as I work in the field and am hoping to do my dissertation on laser surgery here is some information for you:

You have 4 options available to you:

LASIK:
In this procedure the cornea is reshaped by a laser. In effect the laser cuts the cornea to the correct shape, but on a nanoscopic scale. The recovery for this is fast (can be in and out on the same day) and results instantaneous. However is not accepted should you want to enter the armed forces of civilian services as there is a chance that the cornea can dislodge. Allegedly full healing back to the original corneal strength should take about 3 months, however there will always be some sort of inherent weakness due to the collagen fibres running radially across the anterior surface of the eye being cut during the process. If I remember rightly this is suitable for prescriptions from about -10.00DS to +2.00DS (I may be wrong on the figures)

LASEK:
In this procedure the cornea is softened and remoulded like putty using a laser. The results take longer to come to fruition (up to a month or so) however as you are not slicing the cornea open the cornea maintains its original strength. Recover is approximately 3 months. The prescriptions catered for are similar but I believe there is a larger positive range up to +6.00DS (yet again I could be wrong on the figures).

IOL:
You can opt to have a lens placed in front of your actual lens. This effectively acts like a permanent contact lens inside your eye. These procedures are less common and I am not entirely sure of the recovery time, but the long term prognosis is good. The best thing is that this process is the only reversible one.

Not having laser eye surgery:
Depending on your prescription it may be best to avoid surgery altogether. For example if you are a low myope (shortsighted from 0DS to -2.00DS) with astigmatism of -1.00DC or less I would recommend going without. This way you shall never need reading glasses as you age and shall only need distance glasses for board work or driving etc.

What many people do not realise is that laser surgery does not mean you shall not need reading glasses as you age, in short sighted people it will actually move the onset to an earlier age.

Hope this helps!

Not to derail the thread but, since we have some people here with knowledge of Optometry. I want to ask a question. About a yeah ago I had to get glasses in order to pass my vission test to renew my driver's license but, I just barely past even with the glasses because my vision was split and I couldn't read one side of the test card without closing my other eye and vice versa. It's like my eyes are slightly out of alignment. It doesn't normally bother me when I'm not wearing glasses. I'm nearsighted and I usually only wear the glasses when I drive or need to read stuff far away.

Is this something that can be corrected? I realy can't afford to go back to the Optometrist right now or, buy another pair of glasses. I'd like to know if it's fixable if and when I do.

You can have at most two bad eyes.
