In developed countries, cataract is a condition affecting mainly the elderly. When not operated, this opacification of the lens causes a reduction in vision that can lead to blindness.A Rhinoplasty in Las Vegas is something that a surgeon will be able to do easily. A lot of people get a nose surgery done in Henderson and celebrities often get nose jobs as well.
Contrary to an accepted idea, cataract is not a “skin that grows in front of the eye”.
It is a progressive opacification of the normally clear and transparent crystalline lens. The lens is a lens placed behind the iris which converges the light rays on the retina.
Loss of transparency of the lens prevents light from penetrating to the back of the eye, resulting in decreased vision and sharpness of the contours. In the great majority of cases, the cause is aging.
Diagram of the eye
It is a sort of blue, green or brown diaphragm, giving the color of the look.
This transparent lens can be likened to a part of the lens of a camera.
It indicates a thin layer that lines the inside of the eye. It fixes the image as the film of a camera, and then analyzes it in the brain.
Contrary to another idea received, the operation is not carried out by laser.
It is achieved by an improved apparatus which sprays and aspires the opacified lens by means of an ultrasonic probe (phaco-emulsification with ultrasound).
Aims of the intervention
The operation consists of removing the opacified lens and replacing it with a translucent artificial lens.
It is carried out in three stages:
1) small incision in the eye
2) introduction of the ultrasound probe through it
3) positioning of the lens by a mere 6 mm in the envelope of the crystalline lens, called capsule.
Removal of the painful sensation is obtained, in the vast majority of cases, by local anesthesia with:
1) the instillation of anesthetic drops
2) Injection under the eyeball (retrobulbar anesthesia) which causes, for a few seconds, a burning sensation or “throws” that can radiate to the head.
General anesthesia is indicated in exceptional cases (children).
In order to complete your file, the preoperative assessment includes:
An interview with the nurses
An interview with the ophthalmologist
An interview with the anesthesiologist
A blood test: it is not necessary for you to fast
An electrocardiogram: recording of the electrical signals emitted by the heart
A biometry: measurement of the eye by ultrasound allowing the choice of the implant (the lens).
It is important that the day before surgery, you stay fasting from midnight – do not drink, eat or smoke – and this until the operation.
The operation is carried out using a microscope.
After applying a drip and pressure control, a sterile green cloth completely covers your head. An oxygen supply placed in front of your nose helps you to breathe freely.
The procedure lasts approximately 30 minutes. A dressing is applied to the operated eye and removed the same evening.
It is essential that you bring the list of medicines you take to the ophthalmologist.
If you have an infectious condition (flu, colds, coughs, bronchitis, sinusitis, conjunctivitis, etc.) in the days before surgery, it is recommended that the ophthalmology department be Be postponed until your healing.
