As A Life Health Group, we aim to provide the highest quality healthcare services to patients of all ages. Photorefractive keratectomy (PRK) is a safe and effective laser surgery method used to correct vision disorders such as myopia, hyperopia, or astigmatism.
Photorefractive keratectomy (PRK) is a laser surgery method used to reshape the cornea (the transparent outer layer of the eye). During the surgery, the top layer of the cornea (epithelium) is removed, and a laser beam is applied to the cornea to change its curvature. This procedure allows light to focus correctly inside the eye, correcting vision disorders and reducing or eliminating the need for glasses or contact lenses.
Photorefractive keratectomy (PRK) may be recommended in the following cases:
Myopia is a refractive error that occurs when light entering the eye does not focus correctly on the retina. This condition can result from factors such as an eyeball that is longer than normal or excessive curvature of the cornea. People with myopia can usually see nearby objects clearly, while distant objects appear blurry.
Myopia can be caused by genetic factors, environmental influences, and excessive eye strain. It may begin at an early age and can progress over time.
Myopia surgery is a surgical procedure performed to correct the myopia problem in the eye. During the surgery, the shape of the cornea is altered, allowing light to focus correctly on the retina. This surgical intervention treats myopia and can eliminate patients' dependence on glasses or contact lenses.
As A Life Health Group, we guide the myopia surgery process in the most suitable way for you and use the most advanced technology to achieve successful results.
There are several surgical methods for myopia surgery. As A Life Health Group, we offer personalized treatment options for each patient. Here are the most common types of myopia surgery:
1.LASIK (Laser-Assisted In Situ Keratomileusis)
LASIK is one of the most commonly used methods for myopia treatment. In this method, the shape of the cornea is changed using a laser. A thin flap is created from the upper layer of the cornea, and the underlying tissue is reshaped with a laser. This allows light to focus more accurately on the retina.
2.PRK (Photorefractive Keratectomy)
Unlike LASIK, in PRK the upper layer of the cornea is completely removed before the cornea is reshaped with a laser. This is generally suitable for patients with thinner corneas.
3.SMILE (Small Incision Lenticule Extraction)
SMILE is a procedure performed without making a corneal flap. In this method, corneal tissue is removed using laser beams. Since no flap is created in the eye, this procedure is generally less invasive.
Myopia laser surgery is a modern surgical procedure used to correct myopia in the eye. The shape of the cornea is altered using laser beams, allowing light to focus accurately on the retina. Laser myopia treatment eliminates the need for glasses or contact lenses, providing clearer vision.
As A Life Health Group, we ensure safe and effective results with the latest technology laser devices and our expert team used in these types of surgeries.
The recovery process after myopia surgery may vary depending on the surgical method used. However, some general recovery steps observed after myopia surgery are as follows:
Benefits:
Risks:
Myopia surgery is generally suitable for healthy individuals aged 18 and above. However, factors such as whether the eye structure is appropriate, individual health status, and the degree of dependence on glasses or lenses are also evaluated. A Life Health Group determines the most suitable treatment method for each patient through a personalized examination.
Astigmatism is defined as the condition in which light does not focus correctly on the retina. The main cause of this is irregularities in the shape of the cornea or lens. Generally, in astigmatism, the cornea is not round but has an irregular shape, similar to a basketball. This irregularity prevents the eye from focusing light properly.
Normally, light enters the eye through the cornea at the front and, after passing through the lens, focuses on a single point on the retina. In astigmatism, however, light focuses on multiple points due to the shape irregularity of the eye, leading to blurred or distorted vision.
Astigmatism is usually congenital, but it can sometimes develop after eye injuries or surgical procedures.
Astigmatism can cause a range of symptoms due to the irregular shape of the eye. These usually start mildly and gradually but may become more noticeable over time. A Life Sağlık Grubu has listed the common symptoms of astigmatism:
Astigmatism can be classified into different types depending on the type of shape irregularity:
Astigmatism is generally caused by irregularities in the shape of the cornea or lens, which prevent light from focusing correctly on the retina. The main causes of astigmatism are:
The visual experience of astigmatism patients can generally include the following:
Blurry Vision:
In astigmatism, objects, especially at a distance, appear blurry. This occurs because light does not focus correctly on the retina. Astigmatism patients may not achieve clear vision when looking at distant objects, reading, or observing faraway items. Blurriness can also occur at close range.
Distorted Vision:
Astigmatism patients may see distortions and curves even in straight lines. This is especially noticeable on screens and printed materials. For example, a letter or number that should appear straight may look slanted or warped.
Light Halos:
Patients with astigmatism may see halos or glare around lights, especially at night. This occurs due to the scattering of light on the retina.
Poor Contrast Sensitivity:
Astigmatism can make it difficult to distinguish objects in low-light conditions (e.g., in the evening or in dark rooms). Vision may be reduced due to loss of contrast.
Astigmatism can vary in type, and the level of visual impairment differs for each type. At A Life Sağlık Grubu, we summarize the differences in visual experience according to astigmatism types as follows:
Uncorrected Astigmatism:
If astigmatism is not treated, it causes a blurry, distorted, and straining visual experience. People may not see objects at a distance clearly, and reading or observing close objects can also be more difficult.
Mild Astigmatism:
In mild astigmatism, patients may experience slight blurriness in their vision. However, this type of astigmatism is usually easily corrected with glasses or contact lenses, improving visual quality.
Moderate Astigmatism:
In moderate astigmatism, patients experience more noticeable vision problems. Blurry and distorted vision can occur at both near and far distances. In this case, the use of glasses or contact lenses is necessary to correct vision.
Severe Astigmatism:
In severe astigmatism, light focuses at multiple points, causing significant blurriness and vision loss. Severe astigmatism requires correction through laser treatment (e.g., LASIK) or glasses.
At A Life Health Group, we provide a few examples to help you better understand the visual experience of people with astigmatism:
Astigmatism treatment may vary depending on the type and severity of the eye disorder. At A Life Health Group, the main methods we apply in astigmatism treatment are as follows:
Glasses and Contact Lenses
The most commonly used method in astigmatism treatment is glasses or contact lenses. These optical devices are specially designed to ensure that light focuses correctly on the retina. Cylindrical lenses specifically for astigmatism correct the shape irregularities in the eye, providing clear vision.
Laser Treatment (LASIK or PRK)
For those seeking a permanent solution to astigmatism, laser treatment (LASIK or PRK) is a popular option. Laser treatment reshapes the cornea, allowing light to focus correctly on the retina. LASIK is the most commonly used laser treatment method, but other procedures like PRK can also be effective in treating astigmatism.
Astigmatism Surgery (Corneal Implants)
In some cases, surgical interventions such as corneal transplants or implants may be required for astigmatism treatment. These procedures can help permanently correct the shape irregularities in the eye.
Astigmatism can be treated, and visual clarity can be restored. At A Life Health Group, we offer different options for astigmatism treatment:
Glasses and Lenses:
The most common method for treating astigmatism is glasses or contact lenses. Cylindrical lenses specifically designed for astigmatism correct the vision disorder by focusing light properly.
Laser Treatment (LASIK, PRK):
Astigmatism in the eye can be permanently corrected with laser treatment (LASIK or PRK). Laser treatment reshapes the cornea and improves visual quality.
Surgical Intervention:
In some advanced cases of astigmatism, corneal transplant or astigmatism surgery may be required. These surgeries are used to address more severe astigmatism issues.
Myopic astigmatism is a condition in which two different refractive errors, myopia and astigmatism, occur together.
In patients with myopic astigmatism, both refractive errors are present simultaneously, meaning the patient cannot see nearby objects clearly and experiences blurry and distorted vision at all distances due to improper light focus.
People with myopic astigmatism commonly experience the following symptoms:
These symptoms can negatively impact daily life and may worsen if left untreated.
The primary cause of myopic astigmatism is the coexistence of both refractive errors in the eye. Factors contributing to its development include:
Myopic astigmatism treatment aims to correct both refractive errors in the eye. At A Life Health Group, the main methods we use for treating myopic astigmatism are:
1.Glasses and Contact Lenses
Glasses and contact lenses are the most commonly used solutions for myopic astigmatism treatment. These optical devices use specially designed cylindrical lenses to correct both refractive errors simultaneously. The lenses correct both myopia and astigmatism at the same time, providing clear vision.
2.Laser Treatment (LASIK and PRK)
Laser treatment methods such as LASIK and PRK permanently correct myopic and astigmatic errors in the eye. The laser reshapes the cornea, ensuring that light focuses correctly on the retina. This method can be a highly effective solution for patients with myopic astigmatism.
3.Surgical Intervention
In severe myopic astigmatism, laser treatment may not be sufficient, and surgical intervention may be required. Corneal transplantation or astigmatism surgery can be applied to treat advanced myopic astigmatism. These surgeries are performed to correct structural abnormalities in the eye.
In myopic astigmatism treatment, vision is usually corrected with glasses or contact lenses, while recovery can take longer after laser treatment or surgical intervention. After LASIK or PRK, patients can return to daily activities within a few days, but full recovery and optimal vision quality may take several weeks. In surgical interventions, the recovery period can be longer, and patients should follow their doctor's recommendations.
Hyperopia is one of the refractive errors of the eye and usually occurs when light does not focus properly on the retina. This condition causes nearby objects to appear blurry while distant objects are seen more clearly. Hyperopia is commonly known as “farsightedness.” So, what is hyperopia, what are its symptoms, and how is it treated? At A Life Health Group, we have prepared a comprehensive guide to help you understand hyperopia and learn about treatment options.
Hyperopia occurs when the eye is shorter than normal or the cornea or lens of the eye is not properly shaped. Normally, light passes through the cornea and lens and focuses at a single point on the retina. However, in hyperopic eyes, light focuses behind the retina, causing blurry vision.
Hyperopia usually develops due to the following conditions:
People with hyperopia generally experience the following symptoms:
Hyperopia is usually diagnosed by an eye doctor during an eye examination. The eye doctor determines the refractive error through several tests:
Hyperopia is generally treated with glasses, contact lenses, or laser therapy. A Life Health Group lists the main methods used for hyperopia treatment as follows:
1.Glasses and Contact Lenses
The most commonly used methods for hyperopia treatment are glasses and contact lenses. These optical devices help focus light correctly onto the retina. Lenses specially designed for hyperopia improve near vision clarity. Glasses are an effective treatment option, especially for children and older adults.
2.Laser Treatment (LASIK and PRK)
Laser treatment is used to permanently correct refractive errors in the eye. LASIK (Laser-Assisted in Situ Keratomileusis) and PRK (Photorefractive Keratectomy) are widely used laser methods for hyperopia treatment. These laser procedures reshape the cornea to ensure that light focuses correctly on the retina.
3.Refractive Surgery (Lens Implants)
In severe hyperopia cases, especially in individuals over 40, refractive surgery may be used. This method involves implanting artificial lenses into the eye to ensure correct light focusing.
PRK surgery is performed under local anesthesia without the need for general anesthesia. The surgical process involves the following steps:
The recovery process after PRK surgery is longer compared to LASIK surgery. Postoperative symptoms may include mild eye pain, blurred vision, light sensitivity, or redness. These complaints usually resolve within 1–2 weeks.
Like any surgical procedure, PRK surgery carries some risks, including:
