The cornea is is the outer surface of the eyeball in front of the iris and pupil. It is the clear part of the front of your eye.
The corneal surface is the most superficial part.
A scratch on the surface of the eyeball.
Corneal astigmatism can be calculated using keratometry, which measures the curvature of the cornea in different meridians. By determining the steepest and flattest corneal radii, the difference between these measurements (in diopters) can indicate the degree of astigmatism. Additionally, corneal topography can provide a detailed map of the corneal surface, allowing for a more comprehensive analysis of astigmatism. These methods help in diagnosing and guiding corrective measures, such as glasses or contact lenses.
The corneal endothelium governs fluid and solute transport across the posterior surface of the cornea and actively maintains the cornea in the slightly dehydrated state that is required for optical transparency.

Germiniao Ocampo is the one who introduced the corneal transplantation in the Philippines - Also he designed a corneal dissector.
A corneal abrasion refers to a scratch or injury on the surface of the cornea, which can cause pain, redness, and sensitivity to light. "Hisplenia," likely a typographical error for "asplenia," refers to the absence of the spleen, which can increase susceptibility to infections. In individuals with asplenia, a corneal abrasion may pose additional risks, including a heightened chance of infection due to compromised immune responses. Therefore, careful management and monitoring of corneal injuries in such patients are crucial.

Corneal abrasions are usually detected using a slit-lamp with sodium-fluoroscein dye and blue light, which utilizes the concept of fluorescence to pinpoint corneal staining from a corneal abrasion.
Bailey Corneal goes by Bails, Bail, and Bea.
If you stained the eye of a patient with two marginal corneal ulcers using fluorescein, you would see bright green staining in the areas of the ulcers. This is because fluorescein adheres to damaged epithelial cells, highlighting the defects in the corneal surface. The surrounding healthy corneal tissue would appear normal and not fluoresce, making the ulcers more pronounced. Additionally, you might observe a potential underlying conjunctival or limbal involvement depending on the severity of the ulcers.
