It does not directly refer to a type of surgery. However, there are eye operations that may be associated with contact lens use. These treatments are usually surgical interventions to correct vision defects. contact lens surgery Its purpose is to ensure that the person no longer needs to wear glasses or contact lenses in their daily life.
Who Can Have Contact Lens Surgery?
contact lens surgeryaims to eliminate the use of contact lenses. It generally covers procedures known as refractive surgery. It includes techniques such as LASIK, PRK, LASEK, and SMILE and aims to correct various vision disorders.
Surgery candidates must have had no significant changes in their vision prescriptions for at least a year. This indicates that vision is stable and increases the predictability of post-surgical outcomes.
The minimum age limit for most refractive surgery is usually 18 because young people's eye structures may not be fully mature yet. However, ideal candidates are generally 21 years or older.
Candidates should not suffer from major eye problems such as cataracts and glaucoma. LASIK and similar procedures involve reshaping the cornea. Therefore, it is important that the cornea is sufficiently thick and healthy.
Refractive surgery can correct vision disorders such as myopia, hyperopia and astigmatism. However, there are cases where these surgeries may not be suitable for every visual impairment.
It is important for candidates to have realistic expectations about what they can expect from surgery. Changes in hormone levels during pregnancy and breastfeeding temporarily affect visual impairment. Refractive surgery is not recommended during these periods.
It is important for individuals considering these surgeries to first undergo a comprehensive eye examination. Each individual's situation is unique. Potential benefits and risks are evaluated based on individual health status and needs.
In Which Situations Is Contact Lens Surgery Performed?
contact lens surgeryIt includes procedures called refractive and correcting vision defects. These surgeries aim to eliminate the need for people to use glasses or contact lenses in their daily lives. These procedures, which are performed using various techniques such as LASIK, PRK, LASEK and SMILE, are performed under certain conditions.
- Myopia is one of the most common vision defects and causes objects to appear blurry when they are far away. Refractive surgery changes the shape of the cornea, allowing light to focus towards the back of the eye, towards the retina. In this way, it corrects myopia.
- Hyperopia is a condition in which close objects appear blurry. This has to do with the focusing of light behind the retina. Refractive surgery can correct hyperopia by focusing light directly on the retina.
- Astigmatism causes both near and distant objects to appear blurry. Refractive surgery corrects the cornea by making it have a more symmetrical shape.
- Presbyopia occurs with aging and makes it difficult to see close objects clearly. Some refractive surgery methods may help relieve presbyopia symptoms. However, the most appropriate treatment option for this condition may vary from person to person.
- To determine whether you are a candidate for refractive surgery, an eye exam is necessary. General criteria for candidates include a stable eye prescription, adequate corneal thickness, and healthy eyes. Additionally, factors such as the patient's lifestyle, occupation and sports activities are important.
Refractive surgery is not an effective method to correct vision defects. It may not be suitable for everyone. It is important to learn about potential risks, side effects, and consequences.
How is Contact Lens Surgery Performed?
contact lens surgeryIt covers surgical procedures that correct visual defects. These surgeries are performed using modern laser technologies. The most common methods are LASIK, PRK, LASEK and SMILE. The procedure is usually quick, painless and performed on an outpatient basis.
In Lask, local anesthesia is applied with eye drops. A device is placed to keep the eyelid open to prevent the blink reflex. A thin layer of the cornea is created using a microkeratome or femtosecond laser. The flap is removed. Excimer laser reshapes the tissue beneath the cornea. This corrects the vision defect by changing the way light is focused on the eye. The flap is placed over the reshaped cornea and left to heal on its own.
In PRK, local anesthesia and a device that keeps the eyelid open are used. The top layer of the cornea (epithelium) is gently removed with alcohol solution or an instrument. Excimer laser shapes the cornea by applying it directly to the surface of the cornea. The surface layer of the cornea naturally renews itself after the procedure.
LASEK is similar to PRK. However, instead of completely removing the surface layer of the cornea, it is lifted as a flap. After the laser treatment, it is returned to its original place. SMILE, local anesthesia is applied. The femtosecond laser creates a small lens-shaped tissue (lenticule) within the cornea, and this tissue is removed through a small incision made in the cornea. The cornea heals naturally after the incision; this method does not require the creation of a flap.
contact lens surgerycan successfully correct vision defects, but may not be suitable for everyone. It is important to obtain detailed information about potential risks, side effects and expected results. Each method is chosen based on the person's specific needs, corneal thickness, and general health condition.
