The cornea is the clear, dome-shaped covering that protects the front of the eye and plays a crucial role in focusing light onto the retina. It is one of the most important parts of the eye for clear vision. Sometimes, the cornea can develop lines or wrinkles due to a condition called corneal folds or epithelial basement membrane dystrophy. These lines can cause vision disturbances such as blurriness, glare, or double vision.

Treatment for corneal lines typically involves addressing the underlying cause and improving corneal health. This may include lubricating eye drops or ointments to improve corneal hydration, as well as ensuring proper eyelid function to prevent further damage to the cornea.

In some cases, more advanced treatments may be needed, such as a procedure called phototherapeutic keratectomy (PTK). PTK involves using laser technology to remove the abnormal layers of the cornea and promote healing. Another treatment option is the use of special contact lenses.

Keratoconus is a progressive eye disorder that affects the cornea, which is the transparent front covering of the eye. In individuals with keratoconus, the cornea gradually thins and bulges into a cone-like shape, leading to distorted vision. The exact cause of keratoconus is not fully understood, but it is believed to involve a combination of genetic and environmental factors. It typically begins during the teenage years or early adulthood and can worsen over time.

Fortunately, there are several treatment options available for keratoconus. In mild cases, glasses or contact lenses may be sufficient to correct vision. However, as the condition progresses, other interventions may be necessary.

One common treatment is the use of rigid gas permeable (RGP) contact lenses, which help to reshape the cornea and provide clearer vision. Another option is corneal collagen cross-linking, a procedure that strengthens the cornea by applying a special ultraviolet light and riboflavin.

Severe cases may lead to corneal scarring and treated with corneal transplant.
