Astigmatism, or astigmatism, is a mismatch between the surface of the cornea and the inside of the eye. Often the problem occurs at birth and may be associated with short or long eyesight.
Astigmatism is a common defect that can be treated with lenses or surgery, but with the development of medical technologies, it has become easier to treat with Wave light Allegretto ex500.
What is astigmatism?
The human eye is naturally spherical, so the light is refracted evenly on the eye to clearly show the vision. In patients with astigmatism, the eye is shaped in an oval, which reflects light in more than one direction, and allows a certain part of the object to be seen to appear clearly at the expense of the other part, which makes the image blurred.
What are the symptoms of astigmatism?
Symptoms of astigmatism can vary from person to person, some people may not experience any symptoms at all, and the symptoms of astigmatism include:
- Blurry or distorted vision in all directions (near or far).
- Difficulty seeing at night.
- Eye strain or discomfort from vision.
- Squinting (pressing the eyes hard to see).
- Eye irritation.
- Feeling of headache.
What are the methods of treating astigmatism?
Almost all cases can be corrected with eyeglasses or contact lenses, and in some minor cases you may not need this procedure if there are no other vision problems present. While in some other cases astigmatism is associated with some visual problems such as keratoconus, in these cases there are two types of treatment:
1- Corrective Lenses
If you have astigmatism, your doctor will likely prescribe a special type of soft contact lens called toric. It can be made to bend light in one direction more than the other. If your condition is more severe, you may use rigid contact lenses, and your ophthalmologist will determine which is best for you.
2- Refractive processes
Refractive eye surgery refers to any surgical procedure used to repair vision problems. Recent years have witnessed tremendous developments in this field. Laser refractive eye surgery allows many patients to see better than at any other time in their lives.
Most types of vision correction surgery reshape the cornea to allow light to travel through it and focus properly on the back of the eye or the retina.
What is the difference between LASIK and Contoura vision?
LASIK technique is a surgical procedure that uses lasers to correct nearsightedness, farsightedness and astigmatism. In LASIK surgery, a thin incision is made in the cornea using either a microkeratome blade or a femtosecond laser. The surgeon folds the thin wound, then removes some corneal tissue beneath the wound using a laser.
In patients with nearsightedness or farsightedness, the goal of LASIK surgery is to restore the normal shape of the cornea and create light on the retina by making the cornea flat. LASIK can also correct astigmatism by correcting the shape of the cornea that is irregular to the normal shape of the cornea.
While Contoura vision is the latest medical development in the field of refractive surgery. During the annual meeting of the American Academy of Ophthalmology (AAO) in Las Vegas, November 14-17, 2015, Alcon presented new research findings to confirm the technology’s ability to treat glaucoma and cataracts and perform refractive surgeries.
Contoura Vision is a Tapography-guided LASIK technology, designed to provide surgeons with the ability to perform specialized laser procedures on patients with nearsightedness, farsightedness or whichever is associated with astigmatism.
What is wave light allegretto ex500 technology for astigmatism?
It is a new technology characterized by the inclusion of the ALLEGRO analyzer, whose main task is to measure the ability of the eye to see. The device works by sitting the patient in front of him and placing his head on the headrest and focusing on a specific image inside the device. The illuminated target helps the patient to maintain the stability of his eyes while taking the picture.
The device is characterized by high accuracy in reading measurements by means of a regular network of red spots flashing once while taking the picture. With ALLEGRO Analyzer, the patient will be able to get an idea of his own eye defects and understand their causes.
What is the difference between the Wave light allegretto and other technologies?
In just a few minutes, you can start seeing the world in great detail, among the features of the technology:
The doctor helps to correct vision by laser and reshape the cornea, while allowing light to pass through and refract precisely without suffering from astigmatism problems.
Unlike the commonly used techniques, the device takes only seconds of laser treatment on each eye.
You may notice clearer vision immediately after the procedure, and your vision will continue to improve in the following months.
