Keratoconus is a specially designed rigid gas permeable contact lens that is generally used to correct low to moderate myopia. People with high myopia, eye diseases, inflammation and trauma, systemic diseases that lower resistance, and allergy to eyeglass care solution should not wear Keratoplasty lenses.
1. High myopia: As high myopia requires a large amount of shaping power, the risk of wearing keratoplasty lenses is also high. If the degree of myopia is more than 600 degrees or the degree of astigmatism is more than 200 degrees, the effect of wearing keratoplasty lenses is not big, so highly myopic patients should not wear keratoplasty lenses.
2. Eye diseases, inflammation and trauma: Keratoplasty lenses are worn on the cornea, and when there are eye diseases, inflammation and trauma, wearing keratoplasty lenses may aggravate the condition, so patients suffering from eye diseases, inflammation and trauma should not wear keratoplasty lenses.
3. Systemic diseases with low resistance: If you suffer from infectious conjunctivitis, nephritis, renal failure, tuberculosis and other systemic diseases that will lead to low resistance, you are not suitable to wear keratoplasty lenses. Because when the immunity is low, it may lead to the breeding of viruses, affecting the air permeability of the lens, thus affecting the health of the cornea.
4. Allergic to eyeglasses care solution: Since keratoplasty lenses are usually stored in eyeglasses care solution and rinsed before use, but it is inevitable that there is residue of the care solution, so those who are allergic to the eyeglasses care solution should not wear keratoplasty lenses.
Keratoplasty should be worn under the guidance of a medical professional to avoid adverse consequences.
