The most common eye disease among both the young and adults, the most widespread and easiest to treat, is keratoconus, in which the cornea degenerates to appear in a new shape different from its previous one, adversely affecting the quality of vision and life. Therefore, today we will explain the treatment mechanism for keratoconus at Moatassem European eye center, the best center for ophthalmology in the heart of Dubai and the United Arab Emirates. A definition of this condition, its causes, symptoms, and much valuable information await you. We will also conclude this article by answering the most frequently asked questions about this medical condition.
What is keratoconus?
Before discussing keratoconus, we need to understand the cornea of the eye,
which is a distinctive part of the eye characterized by an astonishing anatomical structure.
The cornea is located in front of the iris and is a curved dome made up of five layers, including two membranes. These layers consist of proteins, regular collagen fibers, and glycose.
They have high transparency across all their layers, do not contain any blood vessels,
and obtain the oxygen they need from the external air that touches them.
Therefore, it is positioned outside the eye and covers the front of the eye.
Its primary biological function is to gather incoming light rays into the eye and accurately project them through the regular collagen fibers onto the retina,
where they are converted into neural signals and sent to the brain.
Keratoconus, on the other hand, is a pathological condition characterized by the weakening of the collagen fibers that make up the layers of the cornea, leading to a change in its shape to a cone-like form. This results in a decrease in corneal thickness and a decline in visual quality due to the disruption in the transmission of light rays to the retina, following the change in the shape of the regular collagen scaffolding.
In some cases, keratoconus may be mild and treatable with corrective glasses,
or it may require a treatment procedure using the technique of corneal ring implantation,
which corrects its cone shape and restores its natural curvature.
However, in more advanced cases where no medical or surgical treatment can succeed, corneal transplantation becomes the definitive solution.
Symptoms of keratoconus
It should be noted that the symptoms of keratoconus in most cases become pronounced in the late stages of the condition,
where the state of keratoconus deteriorates and treatment with corrective glasses and simple procedures becomes unfeasible.
However, Dr. Ahmed El-Moatassem’s selection of the latest diagnostic devices and equipment in his center in Dubai
has alleviated these difficulties and made it possible to diagnose this condition at an early stage.
Of course, the initial diagnosis is significantly related to the experience of the ophthalmologist.
The common symptoms and signs include:
- Blurred vision.
- The need to constantly change the prescription of corrective eyewear if worn.
- A rapid decline in visual acuity.
- Difficulty in scrutinizing and reading.
- Headaches resulting from concentrating on objects.
- Scarring and scratches on the cornea in advanced stages.
Causes of keratoconus
Unfortunately, the causes of keratoconus remain unknown and mysterious to this day,
despite the well-known treatments for the condition.
There are no clear cases or factors that lead to the development of this eye disease.
However, based on the experiences of ophthalmologists and research statistics conducted over many years,
the likelihood of developing keratoconus increases among certain patients:
- Patients with a family history of keratoconus, especially among first-degree relatives.
- Cases where the patient frequently rubs their eyes, particularly in instances of seasonal allergies known as ‘Vernal ophthalmia,’ which can lead to itching and a burning sensation.
Treatment of keratoconus
The treatment of keratoconus in the UAE or any other Arab country is divided into several types,
depending on the treatment method and the patient’s condition.
The diagnosis of keratoconus is confirmed after following a series of diagnostic steps,
which include a comprehensive eye examination, measuring corneal thickness, and corneal topography.
Once the condition is confirmed, we proceed to the most appropriate treatment method.
We will provide a brief overview of each of these treatments in the following lines:
• Corrective Medical Lenses
Therapeutic lenses are the first solution in cases of primary keratoconus,
as they are utilized for early diagnosis of this condition. These lenses include several types, such as:
– Rigid Gas Permeable Contact Lenses
They are long-lasting contact lenses that consist of a porous structure and are therefore permeable to gases and vapors.
They are characterized by the fact that they do not take the shape of keratoconus, which is characterized by convexity,
but rather maintain a precise and therapeutic shape, unlike soft cosmetic or medical lenses.
The shape and structure of gas permeable lenses allow vision correction and allow Oxygen reaches the cornea of the eye,
which depends on the oxygen of the outside air, so it is safe for everyone.
– Piggyback Lenses
These consist of a pair of lenses, with the first being made of a soft material that provides a comfortable base for the second lens, which is hard and rigid.
Piggyback lenses are a good and ideal alternative for patients who experience discomfort when using rigid gas permeable lenses, as they offer greater comfort.
– Hybrid Lenses
These are a unique combination of the previous two types.
Hybrid lenses were developed to combine the advantages of both rigid gas permeable lenses and soft dual lenses.
Hybrid lenses feature a hard center designed to correct vision and enhance visual quality while allowing oxygen to pass through,
with soft, comfortable edges that do not cause any irritation or heaviness on the eye.
– Scleral Lenses
Scleral lenses are contact lenses characterized by their large circular diameter that rests on the sclera of the eye,
partially covering both the cornea and the sclera (the white part of the eye).
They are among the best treatments for severe keratoconus cases where previous types of lenses cannot be used due to significant corneal distortion.
These lenses are known for their comfort and significantly improve visual quality,
as they do not exert any direct pressure on the cornea and do not come into direct contact with it;
instead, they rest on the white part of the eye.
• Keratoconus Stabilization
As suggested by the name of this procedure, keratoconus stabilization aims to maintain the condition at a certain level to prevent future deterioration.
This is accomplished through the use of a surgical ophthalmologist special eye drops with the active ingredient “riboflavin” onto the surface of the cornea,
after scraping away the epithelial cells present on it. Subsequently,
a source of ultraviolet light is directed onto the cornea to enhance the strength and bonding of the collagen fibers within its structure and to prevent regression.
This procedure requires advanced medical skills to avoid complications,
which are available at the highest quality at the Moatassem European eye center.
• Corneal Ring Implantation
Corneal ring implantation is utilized for moderate cases of keratoconus that do not respond to keratoconus stabilization or corrective eyewear.
In this procedure, special rings are implanted between the layers of the cornea using femtosecond laser technology.
This, in turn, helps to modify the corneal surface and reduce its steepness. After the corneal rings are implanted,
the steps outlined in the keratoconus stabilization technique are followed to enhance the stability of the keratoconus treatment results and prevent relapse after treatment. It is important to note exceptions, such as in cases of corneal thinning, where ring implantation is not suitable and is instead replaced with surface laser treatment based on corneal topography, followed by keratoconus stabilization.
• Corneal Transplantation
The definitive solution for keratoconus is the complete replacement of the cornea with a defect-free cornea from a donor.
This is performed in cases where the disease is extremely advanced.
However, there are situations where not all layers of the cornea are replaced, which leads to various forms of this procedure as follows:
– Full Corneal Transplantation
In this case, the entire cornea, including all its layers,
is replaced with a completely healthy human cornea obtained from a deceased donor.
– Partial Corneal Transplantation
This involves replacing the superficial layers of the cornea that have experienced excessive steepening and deterioration of collagen connections with new corneal layers,
while preserving the endothelial cells on the surface of the posterior cornea. In this scenario, the risk of immune rejection is minimized.
