Clear Vision Laser Center  >  Conical cornea

Conical cornea

What is conical cornea?


The cornea is a high-transparent concave lens at the front of the eye. Its main function is to assemble the fallen image onto the retinal vision center so that it can be seen.
The cornea consists of 5 layers of vital tissue, forming protein and sugary substances and regular fibers of collagen matrix in perfect harmony to allow the entire optical wave to pass Between collagen voids without any refraction or reflection

In the case of conical cornea
, the cornea loses the cohesion of its collagen material and transforms its surface from the full shape into a funnel or cone, which
leads to increased weakness in corneal thickness resulting in blurred vision with medical spectacles with high astigmatism usually starting from adolescence


What is the cause of conical corneal disease?


It is not yet known the real cause of this disease
found that genetics have a small role in the incidence of this disease and many cases result from eye drowning over many years as a result of spring ophthalmia

Symptoms of conical cornea

The most prominent symptoms are blurred vision
with a rapid change in the measurements of the glasses and the frequent frequency of the doctor to change the size of the glasses and with the passage of time becomes increasingly sharp and the glasses become limited.


How to diagnose conical cornea?

The conical cornea is diagnosed by examining the patient’s eye, topography of the cornea with the five-camera, and measuring the thickness of the cornea


What is the best and most recent treatment of conical cornea?

Coronary corneal disease by its nature is an increasing disease that gradually deteriorates over time until the patient reaches the age of 40. The treatment of the corneal cornea depends on the stage in which the disease was discovered. The development of conical corneal disease can be divided into three stages:


The first phase (simple): where the medical examination is well ****


At this stage the conical cornea is stabilized until the condition stabilizes so as not to deteriorate further
. The surgeon uses composite drops of riboflavin placed on the surface of the cornea after removal of the epithelial cells lining the front surface.
Then, UV rays are injected with specific doses that increase the bonds. Between the fibers of the collagen and strengthen the corneal tissue, which prevents deterioration for many years after this process

Corneal stabilization is a process that has produced a breakthrough in the treatment of conical cornea. Its success rate in corneal stabilization and prevention of disease deterioration is about 99% if performed correctly.

The ease of operation leads some surgeons to complacency in the steps of that process, especially the step of UV radiation on the cornea and leave these steps to non-specialists of nurses and technicians in the operating room, leading to complications of the process. The most recent failure to shed the optimal dose of radiation on the cornea Conical cornea, which are subject to the integrity of the surgeon and his sense of responsibility towards the patient


The second phase (medium): where the patient is not considered good medical glasses ****


At this stage, we treat the conical cornea by implanting minute rings inside the corneal cortex using the femtocene laser, which modifies the meandering and reduces corneal cornea, which leads to a noticeable improvement in the eyesight in most cases. We then fix the conical cornea with UV rays and riboflavin so as not to deteriorate one more time.

In some cases where corneal thickness is allowed, we treat laser conical cornea in Egypt by performing a surface laser with a corneal sign to modify the corneal cornea. Then we install the conical cornea with UV rays and riboflavin so as not to deteriorate again. This process is very successful if The best patient selection and the best device for its condition.

The third stage (severe): in which spoke Atamat cornea or convex very severe cornea ****


At this stage we are treating the conical cornea developed at this stage we are doing a grafting (grafting) of the cornea which are two types:

– Transplantation of the cornea kidney, in which the cornea of ​​the patient is replaced by human cornea of ​​a deceased donor in all its layers without defects conical cornea.

– Transplantation of the cornea or partial cornea, where the surface layers of the patient are replaced with the preservation of the inner layer of the inner lining of the corneal posterior surface, which reduces the immune rejection of the cultivated cornea.

In the case of corneal transplantation, the patient should pay attention to follow-up and adherence to drugs and drops.
