Cost of corneal cross linking surgery for keratoconus stabilization
Have you had problems with your eyesight before? For example, issues such as blurring or seeing shadows or flashes of light? Keratoconus is a common eye condition that develops slowly and progressively over time , which may cause symptoms similar to those mentioned. In this article we will discuss what keratoconus is and how does the condition develop, what are the symptoms and how to treat them.
Corneal cross linking surgery for keratoconus stabilization
Corneal collagen cross linking is a process of strengthening and increasing the molecular bridges that hold the corneal layers together, therefore decreasing the chances of a bulge. It is done by removing of the outer layer of the cornea ( the epithelium) which self regenerates, te application of Riboflavin eyedrops to penetrate into the corneal tissues, and finally direct accurately and precisely measured doses of ultraviolet radiation onto the eye.

What is the keratoconus?
Keratoconus is a common eye diseases where the cornea, which has a natural smooth spherical shape, is weakened, hence bulges to an irregular or conical shape. this irregular surface affects the way the entering light is refracted in the eye causing it to gather at multiple focus points on the retina. This leads blurring of vision and haloes around light. Keratoconus occurs in one or both eyes and develops slowly and progressively and is common around puberty in people aged 10 to 25 or early 20s, but recent studies have shown that keratoconus can develop at any age.
What are the symptoms of keratoconus?
The shape of the cornea changes to an irregular or conical shape, this significantly affects vision and causes blurring which is the most important symptom..
Here are some of the most important symptoms in a keratoconus patient:
- Seeing dark black shadows
- Intolerance or high sensitivity to light
- Blurred vision
- In advanced cases of keratoconus, contact lenses become uncomfortable and less effective where the shape of the cornea becomes like a cone and is clinically clearly visible.
- Swelling and redness of the eye
- Continuous and frequent change in the glasses prescription
What are the causes of keratoconus?
There is no specific or obvious cause of keratoconus, but scientific research has been conducted to find out the reasons and relations of keratoconus. Some scientists believe that the keratoconus is due to genetic and hereditary conditions such as Down syndrome, and congenital Lebers amaurosis , this highlights the importance of asking about family history.
What are the complications of keratoconus?
Some complications may occur as a result of progression of keratoconus; these include sudden painful clouding of vision, a condition known as hydrops
How is keratoconus diagnosed?
In order to diagnose the keratoconus, many different tests can be performed. We must measure the curvature of the cornea, its steepness, its thickness, and this can be done by taking detailed computerized topographic images of the cornea, analyzing them and correlating them to clinical findings.
Who are the patients that are considered candidates for corneal cross linking?
Corneal cross linking is more effective in the early or moderate cases , especially before the cornea becomes clinically conical, and before marked visual deterioration. The most suitable patients for the procedure are
- Who suffer significantly from corneal ulcers and which antibiotics no longer effective, as some studies have found that the process contributes significantly to the treatment of infections
- People who need to undergo other vision corrections such as surface laser surgery in order to strengthen the surface of the cornea before the other operation
Before the operation, the doctor diagnoses keratoconus disease through some important tests, the most famous of which is “computerized topographical mapping the cornea ” or pentacam. the surface of the cornea is photographed and analyzed using the state of the art technology and provides detailed images of the thickness, curvature, shape and deviations of the cornea
What are the operative steps?
The doctor begins to numb the eye through anesthetic eye drops, waits for a few minutes until the full effect of anesthesia takes place. He begins to apply drops of riboflavin eyedrops (vitamin B2) which converts tryptophan into niacin, an amino acid that maintains healthy eyes, applying these drops every two minutes for about half an hour. This is followed by exposure to precisely controlled doses of ultraviolet light.
When does the vision improve after corneal cross linking?
After the end of the operation the doctor prescribes antibiotic and steroid drops and therapeutic contact lenses are applied for about five days after the operation, it is very important to consult your doctor when any complications or abnormal symptoms appear.
Cost of corneal cross linking
Cross linking is performed at a cost ranging from one place to another, because there are several factors on which the cost depends, including the country in which the procedure is performed, the doctor’s experience and the hospital facilities, the type of technology used and the condition of the patient.
Other treatments for keratoconus
Hard contact lenses
They are an alternative to glasses and soft lenses, because these two methods do not provide the visual sharpness required in the case of keratoconus. Hard contact lenses modify the shape of the cornea and hence improve vision.
Corneal transplantation in Egypt is also known as keratoplasty, which is a surgical procedure to replace part or the entire diseased cornea with other corneal tissue from a donor. This helps restore vision and reduce pain, and works to restore the shape of the damaged cornea.
Corneal transplantation is used for a number of reasons, including:
Keratoconus, corneal ulceration, scarring thinning or swelling of the cornea.
PRK surface laser ablation process
PRK is a type of refractive surgery in which eximer lasers are used to treat vision problems caused by refractive errors and is sometimes used in the treatment of keratoconus, but the cross linking procedure step must be done first in this case.
At Optimistic Clinics there is a leading group of highly trained and experienced ophthalmologists covering all ophthalmological subspecialties. Our main aim is to accurately diagnose the patient’s condition and choose to the appropriate center according to the available facilities and equipment needed for the diagnosis and treatment of his condition aiming to provide the best tailored service without siding with a specific procedure or device.
