| | Cornea - Wikipedia, the free encyclopedia |
 | | The cornea contributes more to the total refraction than the lens does, but, whereas the curvature of the lens can be adjusted to "tune" the focus, the curvature of the cornea is fixed. | | | Various refractive eye surgery techniques change the shape of the cornea in order to reduce the need for glasses or otherwise improve the refractive state of the eye. | | | In the techniques used today, parts of the cornea are removed with lasers. |

| | Astigmatism is a condition in which the uneven curvature of the cornea blurs and distorts both distant and near objects. | | | However, some studies suggest that the long-term survival of the new cornea can be a problem. | | | These erosions: (1) Alter the cornea's normal curvature, resulting in temporary vision problems; and (2) Expose the nerves that line the cornea, causing severe pain. |

| | I Know Why Refractive Surgeons Wear Glasses - EyeKnowWhy |
| | The resultant change in the cornea's shape often produces a significant change in its refractive power (and thus the eye's visual perception) that may be perceived as desirable by many patients. | | | The concept of performing invasive surgery inside the aqueous humor (the chamber between the cornea and eye) or between the iris and natural lens in a healthy eye are extremely controversial. | | | Although corneas that are damaged or scarred by refractive surgery can perform, and even perform well, all prospective patients should be aware that vision threatening complications may occur after surgery (immediately or delayed for months or years). |

| | The Cornea |
| | The cornea is the primary (most powerful) structure focusing light entering the eye (along with the secondary focusing structure, the crystalline lens). | | | The nerve fibers enter on the margins of the cornea and radiate toward the center. | | | In advanced stages, there can be a precipitous drop in vision due to sudden clouding of the cornea, referred to as “acute hydrops,” due to a sudden infusion of fluid into the stretched cornea. |

It is a refractive surgery procedure for the correction vision in which a thin layer of the front of the cornea is lifted surgically and the underlying cornea is reshaped using an excimer laser. | | | However, those who know what to expect before, during and after surgery are better prepared and feel more in control of their health care. | | | Once the decision has been made, you will be less anxious and feel more in control if you know what to expect — what the “normal” routine is for this type of surgery. |

| | Keratoconus |
| | When the cornea becomes "opaque" or gray/white (see right photo) from disease or injury or painful from swelling or blisters, it no longer functions as the "clear window" of the eye. | | | Corneal transplant surgery is indicated when a patient cannot wear contact lenses for an acceptable period of time or when the vision, even with contacts, is unsatisfactory. | | | A corneal transplant may be needed when vision cannot be corrected satisfactorily using other procedures such as contact lenses and glasses, or if painful swelling cannot be relieved by medications. |
