What is white or plain water:
It is the opacity of the lens of the eye. The natural lens of the eye is characterized by its high purity, but due to several factors, the most important of which is aging, the lens begins to lose this property, which leads to blurry and blurry vision, which is what is known as cataracts, where the vision is blurred, such as looking through a frozen or distorted window. Which prevents light from completely passing through the opaque lens of the eye, and then vision becomes blurred, and it may affect people at any age.
Causes of cataracts:
To advance in age.
Exposure to ultraviolet radiation.
Trauma or injury to the eye.
Use of cortisone and similar medications for long periods.
diabetes.
Severe myopia
Radiotherapy.
Previous eye surgeries.
Smoking.
Cataract symptoms:
Symptoms vary from one person to another, the most important of which are:
Visual impairment gradually and painlessly.
Blurred and blurred vision.
Sensitivity to bright light, especially when driving at night.
Seeing halos around lights.
Difficulty seeing at night.
Frequent change of glasses or contact lenses.
These symptoms may also be a sign of other eye problems, so you should consult a doctor to check the symptoms.
Cataract treatment:
1- Laser cataract surgery (femtocataract):
This method is considered the latest among the methods of treating cataracts, and it relies on the femtosecond laser to create a small opening in the cornea through which the opaque inner lens is also broken up by the laser.
2- Phaco cataract surgery:
Phaco is a technology that relies on ultrasound waves to break up the cloudy lens of the eye and is the latest method of treating cataracts.
3- Cataract surgery:
It is the removal of cataracts through larger incisions than previous operations and the implantation of a scleral lens inside the eye. This method is resorted to in the case of weakness in the internal cells of the eye that cannot tolerate the use of ultrasound or laser waves, or in neglected cases of cataracts, which has led to an increase in the hardness of the cataracts. To the point that it may lead to damage if an ultrasound device is used.
After breaking up the lens and getting rid of the cataract, the doctor implants the appropriate lens for the patient, which is chosen according to several factors that will be discussed in the next article.
