Keratoconus symptoms may begin mildly and may not seem worrying at first, such as blurred vision or difficulty driving at night. However, over time, the patient may notice continuous changes in vision and that eyesight does not improve even after changing eyeglasses. At this point, questions begin to arise about the causes of keratoconus and why the cornea undergoes this gradual change that affects its natural ability to focus light inside the eye.
Although keratoconus is associated with several factors, such as genetics and continuous eye rubbing, early diagnosis and choosing the right treatment can make a major difference in preserving vision quality and reducing disease progression.
In this article, we will explore the most important information about this medical condition, starting with the causes of keratoconus, the people most at risk of developing it, its symptoms, how to detect it early, how it is diagnosed, the latest available treatment options, the possibility of treating keratoconus with laser, and other important details. Finally, we will explain why Dr. Fouad El-Sayyad is considered one of the leading doctors specialized in managing these cases with precision and professionalism. Keep reading until the end.
What Is Keratoconus?
Before learning about the causes of keratoconus, it is important first to understand the nature of this condition, which directly affects vision quality. Keratoconus is a disorder of the cornea in which its tissues gradually become thinner, causing it to lose its natural shape and bulge outward in a cone-like form instead of its usual round shape.
As the condition progresses, the shape of the cornea affects how light enters the eye, preventing it from focusing properly on the retina. This leads to blurred vision and a gradual decline in visual clarity. The patient may also notice that eyeglasses no longer provide the same level of visual improvement as before.
Keratoconus usually affects both eyes, although it may be more severe in one eye than the other. It commonly begins during adolescence or early adulthood and then progresses gradually over the years. The condition may continue to change until approximately the mid-thirties.
At Dr. Fouad El-Sayyad Center, led by Dr. Fouad El-Sayyad, Consultant Ophthalmologist and Eye Surgeon, American Board Certified, we focus on managing keratoconus cases with high precision using the latest diagnostic methods to accurately identify the causes of keratoconus and create a suitable treatment plan for each patient based on their condition. Continuous follow-up is also provided to preserve visual efficiency and reduce disease progression with the best possible results.
What Are the Causes of Keratoconus?
Until now, the causes of keratoconus have not been definitively identified. However, the condition occurs as a result of a combination of genetic and environmental factors that affect the strength and structure of the cornea, which in turn affects visual clarity.
The most common factors and causes of keratoconus include:
Genetic Factors and Family History
Genetic factors play an important role in increasing the likelihood of developing keratoconus. The risk is higher in people who have a family history of the disease, suggesting the presence of a genetic predisposition that may affect corneal strength over time.
Continuous and Aggressive Eye Rubbing “Due to Allergies or Vernal Conjunctivitis”
Frequent and forceful eye rubbing is one of the factors that may weaken corneal tissues, especially in people who suffer from allergies or vernal conjunctivitis. This may contribute to accelerating the change in corneal shape and weakening its natural stability.
Weak Collagen and Connective Tissue Disorders
The strength of the cornea depends on fine collagen fibers that help maintain its structure and round shape. When these fibers become weak or disrupted, the cornea begins to lose its stability and gradually bulges forward, resulting in the cone-like shape characteristic of keratoconus.
Excessive Exposure to Ultraviolet Rays
Continuous exposure to ultraviolet sunlight without adequate protection may weaken eye tissues over time and increase the cornea’s vulnerability to other factors that lead to changes in its natural shape.
With the multiple possible causes of keratoconus, early diagnosis and continuous follow-up become essential to reduce disease progression and preserve visual efficiency. To receive an accurate evaluation and a suitable treatment plan, you can book your consultation with Dr. Fouad El-Sayyad Center to monitor your condition using the latest technologies and create a personalized treatment plan that ensures the best possible results for maintaining eye health and vision quality.
Who Is Most at Risk of Developing Keratoconus?
Keratoconus usually begins to appear during adolescence or the early twenties and may progress gradually over several years. The shape of keratoconus often appears in both eyes but to varying degrees. Some groups are more likely to develop this condition due to genetic, behavioral, or health-related factors.
The people most at risk of developing keratoconus include:
- Teenagers and young adults, as the condition often begins at this age.
- People with a family history of keratoconus.
- People who suffer from eye allergies or frequently rub their eyes.
- Patients with certain disorders such as Down syndrome or connective tissue disorders.
- People who have general weakness in corneal tissues or collagen-related problems.
Therefore, identifying high-risk groups and understanding the causes of keratoconus early is an important step toward detecting the condition in its early stages, reducing its chances of progression, and limiting its effect on vision quality through timely medical intervention. This helps preserve stable vision in the long term.
Are Vision Correction Procedures “LASIK” One of the Causes of Keratoconus?
LASIK vision correction procedures are not a direct cause of keratoconus. However, they are not suitable for people who already have the condition, even in mild cases. This is because LASIK procedures depend on removing part of the corneal tissue to reshape it, which reduces corneal thickness and weakens its structure.
Since keratoconus occurs due to weakness and thinning of the corneal tissues, performing LASIK in these cases may further weaken the cornea and worsen the problem instead of treating it. Therefore, these procedures are avoided in keratoconus patients, and safer alternative treatment options are chosen according to the patient’s evaluation.
What Keratoconus Symptoms Should You Pay Attention To?
After learning about the causes of keratoconus, it is also important to recognize the symptoms caused by this condition. These symptoms often begin gradually and may not be noticed by the patient at first, but they become clearer over time due to the changing shape of the cornea and its effect on vision.
The most common symptoms of keratoconus include:
- Persistent blurred and unclear vision.
- Frequent need to change eyeglass prescription.
- Difficulty seeing distant objects clearly.
- Halos or glare around lights, especially at night.
- Increased sensitivity to bright light.
- Poor vision while driving at night.
- Frequent urge to rub the eyes due to discomfort.
- Recurrent headaches caused by eye strain.
If you experience any of these symptoms, it is recommended not to ignore them and to book a consultation with Dr. Fouad El-Sayyad Center to receive a comprehensive evaluation and a suitable treatment plan that helps preserve vision as much as possible.
When Should You Visit an Eye Doctor Immediately?
You should visit an eye doctor immediately if you notice any of the following symptoms:
- Rapid or noticeable decline in vision without a clear reason.
- Vision does not improve despite changing eyeglasses.
- Frequent need to change eyeglass prescription within a short period.
- Persistent blurred or double vision.
- Suspicion of keratoconus shape or irregular corneal surface.
- Presence of keratoconus risk factors and causes, such as frequent eye rubbing or a family history of the disease, along with worsening vision.
In these cases, any change in vision should not be ignored. Early evaluation by an eye doctor is the most important step to protect the eye from keratoconus complications and preserve clear, stable vision in the long term.
How Is Keratoconus Accurately Diagnosed?
Keratoconus is diagnosed through a set of precise examinations that aim to evaluate the shape of the cornea using advanced devices. These tests help the doctor detect the condition in its early stages and accurately determine its severity.
The most important methods and technologies used to diagnose keratoconus include:
- Eye Refraction Test: To determine the degree of vision weakness and the type of correction needed.
- Slit-Lamp Examination: To evaluate the shape of the cornea and detect any changes in its structure.
- Keratometry: To measure the curvature of the cornea and identify its basic shape.
- Corneal Imaging Using OCT or Tomography: To create an accurate map of the corneal surface and thickness and detect early changes.
At Dr. Fouad El-Sayyad Center, led by Dr. Fouad El-Sayyad, Consultant Ophthalmologist and Eye Surgeon, American Board Certified, we use the latest diagnostic technologies to accurately evaluate corneal conditions and connect the results with the possible causes and risk factors of keratoconus. This helps us create an appropriate follow-up and treatment plan that provides the best protection for vision and reduces disease progression.
What Are the Latest Keratoconus Treatment Methods?
Keratoconus treatment depends on the degree of disease progression. In the early stages, the doctor usually begins with corrective lenses or rigid contact lenses to improve vision quality before moving to more advanced treatment procedures that aim to stop disease progression or restore vision in advanced cases.
The latest available treatment methods include:
Corneal Cross-Linking
Corneal cross-linking is one of the latest non-surgical procedures. It strengthens collagen fibers inside the cornea using special drops and ultraviolet light exposure, helping increase corneal rigidity and stop the deterioration of its shape.
Intracorneal Ring Implantation
This procedure involves inserting tiny rings inside the corneal tissue to reshape the cornea and improve the regularity of its surface. This reduces abnormal bulging, significantly improves vision quality, and may reduce dependence on eyeglasses or contact lenses.
Corneal Transplantation “Lamellar or Full-Thickness” for Advanced Cases
In advanced cases that do not respond to other treatments, corneal transplantation may be needed, either partially or fully. The damaged tissue is replaced with healthy donor corneal tissue to restore visual clarity as much as possible.
To receive a personalized consultation and determine the most suitable treatment for your condition, contact Dr. Fouad El-Sayyad Center to accurately diagnose the causes of keratoconus and benefit from the latest advanced treatment technologies, with continuous follow-up to achieve the best results and preserve stable vision in the long term.
Complications of Neglecting Keratoconus
After learning about the causes of keratoconus and how it is treated, it is important to clarify that neglecting treatment may cause the condition to gradually worsen. This can lead to clear deterioration in vision quality and difficulty correcting vision through traditional methods such as eyeglasses or contact lenses.
Over time, more serious complications may appear and affect visual safety, such as:
- Increased nearsightedness and continuous changes in eyeglass prescription.
- Severe blurred vision that does not improve with medical lenses.
- Formation of corneal scars that affect visual clarity.
- In very advanced cases, severe vision deterioration may occur and may reach significant visual impairment or blindness.
As these complications progress, early medical intervention becomes the most important factor in preserving visual efficiency and reducing the chances of deterioration or the need for more complex procedures such as corneal transplantation.
Can Keratoconus Be Treated with Laser?
Laser is not used as a direct treatment for keratoconus itself because the main problem lies in corneal weakness, thinning, and shape distortion. This makes traditional laser procedures, such as vision correction, unsuitable in most cases. Therefore, laser is not considered a primary treatment for the disease.
However, in some cases, laser may be used as part of precise therapeutic procedures, such as intracorneal ring implantation. In this case, femtosecond laser is used to create highly accurate channels inside the cornea, allowing the rings to be placed safely. This helps improve corneal shape and reduce visual distortions, which has a positive effect on vision quality.
Can the Causes of Keratoconus Be Prevented?
There is no guaranteed way to completely prevent keratoconus, but the likelihood of developing it or slowing its progression can be reduced by limiting the factors and causes that affect corneal strength over time.
The most important preventive measures include:
- Avoid rubbing the eyes frequently or aggressively, especially in cases of allergy or itching.
- Treat eye inflammations and allergies that may increase the urge to rub the eyes.
- Wear sunglasses when exposed to sunlight to protect the cornea from ultraviolet rays.
Following these simple guidelines helps maintain corneal health and reduce the chances of disease progression. It is also necessary to consult a specialist such as Dr. Fouad El-Sayyad if you notice any change in vision level or symptoms that may indicate the beginning of the problem, to ensure early diagnosis and a proper treatment plan at the right time.
