Chances of developing Keratoconus?

Question

Below is the reading of my eye vision problem.
BC 8.5, SPH -1.25, CYL -2.25, AX 170 for right eye
BC 8.5, SPH -5.25, CYL -2.25, AX 180 for left eye

These are not the up-to-date reading. I have just realised that my astigmatism has increased again in both eyes as i know it is a dot of light but i see it as a "star", when i squint my eye i can see the light is not 'star' but a dot. My eyes are pain sometimes and i am very sensitive to light, even watching the tv sometimes make me feel that my eyes are exposed to very bright light. I can sometimes see small floaters mostly below my eyes.

I am wearing bausch& lomb soft contact lenses with the prescription above. I am facing the computer everyday. I am worried that my eyesight will get worsen in future. Is there anyway to prevent further increase/worsening of the problem?

I used to cry a lot during my teenage because of my depression. I wonder if that had impaired my eyesight too?

Answer 1

Keratoconus is purely a genetic condition.

It's not just a high degree of myopia with high levels of astigmatism, and your Rx isn't at all extreme.

Neither pain nor photophobia are indicators of keratoconus, which is usually a very slow pain-free condition in the early stages.

It comes in a variety of inherited forms. If dominant, it is likely to be present in some of your older relatives.
If recessive, it may not be known in the family, but just grop up when two "carriers" both pass the relevant gene to an offspring. This is why it historically has been more common in certain areas of the world where more close kin marriages occured.

So overall:
you either will have keratoconus ( very unlikely) or you will not, but nothing you do will affect that one way or the other.

On your Rx, beyond regular check-ups, there is nothing particular to do or worry about.
Good nutrition, posture, and reading habits are advisable, but that should be said to *everyone*!
