Toric Lenses
Toric lenses are used in the treatment of astigmatism. Astigmatism is known as a refractive error that can be seen in both hymeropia and myopia. In eyes with asyggmatitis, both distance and near vision are impaired, resulting in a blurry image. In addition to this disorder, objects that normally have a round shape appear in an oval shape. At night, the lights reflect more and disturb the eyes.
Intraocular lenses are generally used in hymeropic patients who have difficulty seeing both near and far. However, it can also be used in patients over 40 years of age. The natural lens that has lost its function in the intraocular lens is removed and replaced with an artificial lens. However, there are also lenses produced to correct astigmatic eyes. These are called toric lenses. Toric lenses are a type of intraocular lens and are frequently used today. With the development of new technologies, many lenses and lenses have become available. Nowadays, in addition to distance and near vision, astigmatism can also be treated during surgical interventions. Successful results are obtained with these intraocular lenses for astigmatism disorders up to 6-7 degrees.
HOW IS THE SURGERY PERFORMED?
First of all, the patient is given the necessary examination, measurements and tests. Then, the intraocular lens model that best suits the patient is chosen by the physician. Toric lens applications are performed almost the same as a normal cataract surgery. In this surgery, anesthesia is first administered with drops. Then, the natural lens in the eye whose function is impaired is removed and a toric (astigmatic) lens is placed in its place. After the surgery, the eye is covered with a bandage. This bandage is removed by the doctor during the check-up the day after the surgery. The patient can continue his daily life without any problems with his vision on the same day. The doctor then gives the patient the drops he has determined and asks the patient to use these drops regularly after the surgery. After the surgery, routine checks are performed weekly and monthly. After this surgery, the patient is no longer suffering from astigmatism. Toric lens treatment takes approximately 15 minutes.
WHAT ARE THE ADVANTAGES?
Opportunity to treat refractive problems in almost every degree of eye
Possibility of rapid improvement in vision
Predictable results
Chance of getting rid of high degree astigmatism
No tissue loss or thinning in the cornea
High optical quality
It can be performed together with other eye surgeries if necessary.
be reversible
Opportunity to get rid of glasses and contact lenses
Toric lens treatment is performed in the same way as standard cataract surgery. This method also provides improvement in the same process, just like cataract treatment. The method does not have any risk factors that increase the patient's risk of developing other eye diseases in the future. This method also does not prevent other surgical interventions. Toric lenses are lenses produced with high technology that patients with astigmatism can use safely.
However, if the patient has astigmatism due to the cornea, astigmatism can be corrected with a toric lens during cataract surgery.
