Understanding Corneal Disorders and the Need for Penetrating Keratoplasty
The cornea, a transparent dome-shaped structure at the front of the eye, is crucial for clear vision. When afflicted by various disorders, the cornea can undergo changes that impair its ability to refract light properly onto the retina, leading to visual impairment. Penetrating Keratoplasty (PKP) emerges as a critical intervention for individuals grappling with a spectrum of corneal disorders, each presenting its unique challenges. Keratoconus: A Common Indication for PKP: One of the primary corneal disorders prompting the need for Penetrating Keratoplasty is keratoconus. This progressive condition involves the thinning and conical bulging of the cornea, resulting in distorted vision. As the cornea loses its regular shape, conventional corrective measures such as eyeglasses or contact lenses become less effective. PKP, with its ability to replace the distorted cornea with a healthy donor cornea, stands as a definitive treatment option for advanced stages of keratoconus. Corneal Scarri
