Optometrist explains how to keep an eye on your eye health

One of the very first signs of diabetes is a change in your vision. When your blood glucose is elevated, the lens inside your eye can change shape. When this happens the patient will become more nearsighted, or less farsighted. The patient also may notice increased thirst or increased frequency of urination.

How does laser vision correction work?

Suction is applied to your eye to make it hard, then an instrument rolls across your eye to make a flap. Your eye is treated with the laser, and the flap is put back. Your eye will burn or sting for about six to eight hours after the procedure. The laser reshapes the cornea to correct nearsightedness, farsightedness and astigmatism. The laser is unable to correct the aging of the eye, which is decreased focusing. So once you are in your 40s you will need to wear glasses for reading. Laser correction should not be performed unless your glasses prescription has been stable for at least a year.

Are the effects of laser vision correction permanent?

While there is no indication laser vision correction is not a permanent effect, some people will have changes that may require an enhancement, or additional laser, after some period of time. Personally, I had laser vision correction in 1996 and my vision at distance is still great. I do need to wear glasses for reading because I am 53.

Should you decide to have laser vision correction, it is very important to choose an experienced surgeon. Be sure to ask your eye doctor whom they would recommend or, even more importantly, whom they would go to themselves or send their family to.
