Generally, there are two approaches to treating keratoconus: slowing the progression of the disease and improving vision. Treatment for keratoconus depends on the severity of your condition and how quickly the condition is progressing. This type of testing can often detect early signs of keratoconus before the disease is visible by slit-lamp examination. Corneal tomography also can measure the thickness of the cornea. Special photographic tests, such as corneal tomography and corneal topography, record images to create a detailed shape map of the cornea. This determines the basic shape of the cornea. This exam involves focusing a circle of light on the cornea and measures the reflection. The eye doctor evaluates the shape of your cornea and looks for other potential problems in the eye. This test involves directing a vertical beam of light on the surface of the eye and using a low-powered microscope to view the eye. Some doctors may use a hand-held instrument called a retinoscope to evaluate the eyes. This device helps judge which combination gives you the sharpest vision. You may be asked to look through a device that contains wheels of different lenses, called a phoropter. This test uses special equipment that measures your eyes. Other tests also may be done to find out more about the shape of your cornea. Additionally, your age and the thickness of your cornea will also be taken into account when considering your candidacy for CXL.To diagnose keratoconus, your eye doctor will review your medical and family history and conduct an eye exam. Who is a candidate for corneal collagen crosslinking?Īn ideal candidate for CXL will have keratoconus progress for the past 12 -14 months. You may experience blurry vision and sensitivity to light at first, but your vision will return and possibly improve over time. Patients who may experience the most improvement in vision are usually older in their 50s or 60s and have keratoconus. Yes, corneal collagen crosslinking can improve your vision by improving the shape of the cornea. Does corneal collagen crosslinking improve your vision? If necessary, corneal collagen crosslinking can be repeated if the treatment is not effective. This also depends on how old the patient is when they undergo corneal collagen crosslinking. While we don’t know precisely how long corneal collagen crosslinking will last, the results may be permanent in some cases. The effects of your corneal crosslinking will last for many years. How long does corneal collagen crosslinking last? It is the only treatment available to halt progressive keratoconus from getting worse and can help to prevent a corneal transplant. CXL uses eyedrop medication and ultraviolet (UV) lights to strengthen the tissues in your cornea and stop them from bulging out. In most cases, complications of a cornea transplant can include an eye infection, a rise of pressure within the eyeball which can lead to glaucoma, or retinal problems like retinal detachment or swelling.Ĭorneal Collagen Crosslinking, or CXL, is a treatment method for keratoconus. This rejection will require immediate medical attention to either get another cornea transplant or to prescribe medication. There is a possibility for your body’s immune system to reject the donor’s cornea. How serious is a cornea transplant?Ī cornea transplant is a relatively safe procedure, however, like any surgical procedure, there is a risk of complications. You can also expect to use steroid or antibiotic eye drops daily for several months to a year. Following your procedure, it’s important not to rub your eyes, avoid intense exercise or heavy lifting, avoid manual labor work for 3-4 months and avoid contact sports and swimming until your doctor advises you to. Following your cornea transplant, you can expect to treat your eyes very carefully. The recovery process for a corneal transplant can last anywhere from a couple of weeks to a year. How long does it take to recover from a corneal transplant?
