عمل جراحی لیزیک چیست و برای چه افرادی مناسب میباشد؟
لیزیک یکی از دقیق ترین روشهای جراحی عیوب انکساری چشم محسوب میشود که پرتوهای دریافتی نور را به درستی روی قرنیه چشم متمرکز میکند. The purpose of performing LASIK is to achieve a clear and transparent vision.
Usages of LASIK surgery
- Myopia: When a person has a large eyeball or the curvature of the cornea is such that the light is concentrated in front of the retina, it is difficult for him to see distant objects.
- Camera: On the other hand, when a person has an average eyeball or the curvature of the cornea is such that the light is focused behind the retina, it becomes difficult for him to see close objects and in some cases far away objects. It happens that the vision of near and far objects becomes difficult.
Lasik surgery side effects
Like any other surgery, LASIK also has complications, which are:
- In nearsighted people, the use of LASIK is often associated with very little removal of corneal tissue; As a result, the patient will not have a clear vision and need to undergo surgery again.
- On the other hand, there is a possibility that too much tissue will be lost during the LASIK procedure. In such conditions, it becomes more difficult to correct the cornea.
- After the LASIK operation, there is a possibility that the vision condition will return to the condition before the operation. Effective causes in this field include incomplete healing of wounds, hormonal imbalance, or pregnancy.
- In very few cases, a person may lose his vision or not have a clear or transparent vision.
- Astigmatism: if tissue removal is done irregularly, the person may have a problem. It becomes astigmatism. In such cases, re-operation, use of glasses or contact lenses is required.
- After LASIK surgery, a person may have difficulty seeing objects at night. In such cases, the person experiences blurriness, double vision, or seeing light halos around light sources.
- Dry eyes: LASIK reduces the production of tears in the eyes, which may last for 6 months. Dry eyes reduce the quality of construction. Using eye drops can be very beneficial. In very severe conditions, the person may be re-operated to check the tear ducts completely.
- Complications due to peeling: LASIK operation involves removing layers from the front surface of the cornea. This layer is connected to the surface of the cornea with a hinge, and after lifting it from the surface of the cornea, the laser is used to restore and change its curvature. At the end, the said layer is returned to the surface of the cornea and the dressing lens is placed. In this condition, the patient may suffer from infection, inflammation and increased tear secretion. If the exfoliation of the cornea is not done correctly, the outer layer (epithelium tissue) may not adhere well to the underlying part and grow abnormally. It is recommended that doctors refrain from performing this surgery:
- Autoimmune diseases such as rheumatoid arthritis
- Immune deficiency conditions caused by diseases such as HIV or the use of immunosuppressive drugs.
- Hough Continuous Eye
- Unstable vision due to certain medication, hormonal changes, pregnancy, breastfeeding or aging
