What Are the Symptoms of Corneal Diseases?

Because the cornea plays a key role in visual clarity, its diseases often cause noticeable changes in vision.

• Sudden or progressive vision loss: Vision may become blurred or less sharp when the cornea loses its transparency or its shape becomes distorted.

• Severe eye pain: Corneal infections or injuries can cause intense pain, stinging, burning, and discomfort.

• Redness and excessive tearing: The eye may become significantly red and watery as a response to infection or irritation affecting the cornea.

• Light sensitivity (photophobia): Increased discomfort or pain when looking at bright lights is a common symptom of corneal disorders.

• Halos and double vision: Especially in patients with keratoconus, seeing halos around lights or experiencing distorted or double vision, even in one eye, is a common symptom.
