Post Cornea Transplant & Custom Contact Lenses In Huntington Beach, California
A corneal transplant performed on a patient is often a result of an eye disease or eye injury to restore vision. Post a corneal transplant, patients often require specialty contact lenses to correct vision to achieve clear and comfortable vision.
Two Common Forms Of Corneal Transplants
Most corneal transplants that are performed come in two forms: Penetrating keratoplasty (PK) and Endothelial Keratoplasty (EK).
Penetrating Keratoplasty (PK): A Corneal Transplant Of The Full Thickness Of The Cornea.
Endothelial Keratoplasty (EK): A Corneal Transplant Where Only The Back Layer Of The Cornea Is Corrected.
What Leads To A Corneal Transplant?
Surprisingly, corneal transplants or even partial cornea transplants are performed every year for numerous reasons. Eye diseases that are left unmanaged or uncorrected, even cataracts, glaucoma, or age-related macular degeneration, may require a corneal transplant in severe cases. Often, a corneal dystrophy or corneal degeneration may demand a cornea transplant overtime. In general, any diseased cornea can lead to blindness without proper care from an eye doctor.
What Is Keratoconus?
A semi-rare disease called keratoconus often requires some form of cornea surgery to stabilize the condition, such as corneal collagen crosslinking or a cornea transplant. Keratoconus is when the anterior cornea things and protrudes, which distorts the shape of the cornea. Often, patients with advanced keratoconus will see haloes suffer from eye pain, blurry vision, and sensitivity to light and their surrounds. While not fully understood, keratoconus is likely due to both genetic and environmental factors.
Scleral Lenses & Post-Corneal Transplant Surgery
Cornea transplants tend to result in irregular corneas as the transplant can’t adapt fully to the eye. may recommend rigid gas permeable lenses (RGP’s), hybrid contact lenses or scleral lenses to provide you with clear vision & comfort without the need of any further surgery.
Scleral lenses are often the optimal choice as they provide the lens is designed to vault over the cornea entirely. Even after a corneal transplant, the cornea may still be considered irregular & diseased. Scleral lenses allow one’s cornea to remain hydrated, provide clear vision, and avoid any risk of corneal scarring. Other options are possible, yet scleral lenses make for a safe alternative that won’t negatively affect the cornea, and in many cases, can be covered by medical insurance.
