The cornea is the transparent, dome-shaped front layer of the eye that covers the iris, pupil, and anterior chamber. It plays a crucial role in focusing light onto the retina, contributing to most of the eye’s optical power. Being avascular (without blood vessels), the cornea gets its nutrients from tears and the aqueous humor. Damage, infection, or disease affecting the cornea—such as keratitis, corneal dystrophies, or keratoconus—can cause pain, blurred vision, and even vision loss. Treatment depends on the condition and may include medications, laser therapy, or corneal transplantation in severe cases.

• Definition: Transparent, outermost layer of the eye.
• Function: Protects the eye and focuses incoming light onto the retina.
• Structure: Five layers – epithelium, Bowman’s layer, stroma, Descemet’s membrane, endothelium.
• No blood supply: Gets nutrients from tears and aqueous humor.
• Common disorders: Keratitis, keratoconus, corneal ulcers, dystrophies.
• Symptoms of corneal problems: Redness, pain, blurred vision, sensitivity to light, excessive tearing.
