Keratoconus is an eye disease in which the cornea of your eye changes in shape. Rather than being the regular rounded shape, it takes on a cone shape, which gives the appearance of a bulging eye. This condition results in vision problems that may start out as nearsightedness and not be diagnosed at first. The cause is not known, but it generally shows itself during adolescence. There are a few situations in which you should look into keratoconic exams.
The first indication is a blurring of vision that doesn’t seem to be able to be corrected with glasses. Another situation is when your nearsightedness worsens or you notice halos, glare and other night vision difficulties.
Another time when you should look into keratoconic exams is if you are considering LASIK surgery. It is important to test for keratoconus prior to having LASIK because the surgery cannot be performed even if you have only borderline keratoconus.
Lastly, if you have this eye disease, your children should have keratoconic exams starting when they reach ten years of age and continuing through their adolescent years.
Not all optometrists are familiar with doing keratoconic exams. There is nothing wrong with having this exam done even if you are not an at-risk youth or experiencing problems. It can be part of your routine eye exam if you desire.
