Q:My 13-year-old son was just recently diagnosed with keratoconus in both eyes. We have had him fitted for soft contact lenses. Will that control it or will he need to try other options? One eye is not so bad, but the other eye is very bad. — A. A:Contacts improve vision, but...
On this basis, 73 patients were designated as having evidence of keratoconus in both eyes. In order to quantify the degree of asymmetry between fellow eyes in these bilateral patients, intraclass correlation was calculated for best spectacle corrected visual acuity (BSCVA) and for 13 different ...
Q:I have severe keratoconus in both eyes and have been using GP lenses for the past 20 years. Recently my son, who is 9, was advised to wear eyeglasses with a spherical power of -1.25 D for both eyes and .5 D of cylinder for the right eye. Could this be keratoconus or the start...
protruding from the center or just below the center. The resulting shape is often characterized as the shape of a cone. This irregular surface causes blurry vision. The blurry vision is not correctable by normal glasses or contact lenses. Keratoconus usually involves both eyes, however one eye ...

Usually, keratoconus occurs in both eyes, and involves the central cornea with the apex of the cone just below the visual axis. Approximately 50200 of every 100,000 people are afflicted with KC. In the US, a study found a prevalence of 54.5 per 100,000 people....
meaning it occurs in both eyes at the same time. Progressive worsening of vision in both eyes at the same time can also be a sign of keratoconus. Other signs include higher levels of astigmatism or visual distortions that are difficult to correct with glasses. There are a number of direct ...
Asymmetric visual complaints: Although keratoconus typically affects both eyes, it may present with asymmetric symptoms, with an eye more severely affected. About 41% of patients report unilateral disease at the time of diagnosis. Münson sign: Advanced keratoconus may result in the Münson sign, cha...
Keratoconus usually affects both eyes but can be asymmetric. It often appears in the late teens or early twenties and is a progressive condition. As the cornea becomes steeper and more irregular in shape, nearsightedness and irregular astigmatism develop. ...
However, newer biometers, like the IOLMaster 700, can quickly capture images even in difficult patients. In fact, one study showed the average time to complete biometry measurements in both eyes was significantly shorter for the IOLMaster 700 compared with the Lenstar LS900 (Haag-Streit) (44...
