Keratoconus Disease is a progressive eye disease characterized by the thinning and outward bulging of the cornea into a cone shape. This condition causes the cornea to take on an irregular shape, preventing light from focusing properly on the retina, resulting in symptoms such as blurred vision, light sensitivity, and reduced vision quality. While methods like glasses and contact lenses may be sufficient for vision correction in the early stages of the disease, surgical and laser treatments such as corneal collagen cross-linking (CXL), intracorneal ring implantation, and corneal transplant may be required in advanced stages.
Keratoconus treatment involves various methods aimed at halting the progression of the disease and improving visual quality. Review detailed information about keratoconus surgery, keratoconus laser treatment, and other treatment options.

Keratoconus Surgery
Keratoconus surgery includes surgical procedures aimed at correcting the shape of the cornea or replacing the damaged tissue with a healthy donor cornea. The surgical method to be applied is determined by considering factors such as the patient’s corneal thickness, the stage of the disease, and overall eye health.
Types of Keratoconus Surgery
As Keratoconus disease progresses, traditional methods such as glasses or contact lenses may become insufficient for correcting vision problems. In this case, surgical interventions are applied to strengthen the structure of the cornea, correct the shape irregularity, and improve visual quality. Keratoconus surgeries can be performed using various methods depending on the stage of the disease and the patient’s eye structure.
Surgical treatment options for Keratoconus include various techniques such as corneal transplant (keratoplasty), intracorneal ring implantation (Intacs), and corneal collagen cross-linking (CXL). These surgeries are performed to slow or halt the progression of the disease, improve vision, and make the patients’ daily lives more comfortable. Each method has different advantages, disadvantages, and applicability criteria.
- Corneal Transplant (Keratoplasty): A method preferred in advanced stages of keratoconus. A healthy donor cornea is transplanted to replace the damaged corneal tissue. There are two types: Penetrating Keratoplasty (full-thickness transplant) and lamellar keratoplasty (partial-thickness transplant). The postoperative recovery period is long, but it is a permanent solution.
- Ring (Intacs) Implantation: The curvature of the cornea is reduced by small plastic rings placed inside the cornea. It can slow the progression of the disease by increasing the structural integrity of the cornea. It is a minimally invasive method and offers a fast recovery period.
- Cross-Linking (CXL): UV light and riboflavin are used to stiffen the cornea. A highly effective method for halting the progression of the disease. If applied in the early stage, it can eliminate the need for surgery.
Keratoconus Laser Treatment
Keratoconus laser treatment offers an effective alternative, especially for patients who have difficulty using glasses and contact lenses. These treatment methods aim to improve visual acuity and control the progression of the disease by reshaping the cornea. However, laser treatment is generally not recommended in advanced stages of keratoconus, and its applicability is determined by considering factors such as the patient’s corneal thickness, the level of the disease, and overall eye health. Keratoconus eye laser treatment aims to improve visual quality when applied in early and intermediate stages. Keratoconus laser treatment reduces the irregular curvature of the cornea, enabling light to focus on the retina more correctly. It can be an effective alternative, especially for patients who have difficulty using glasses or lenses.
Types of Keratoconus Laser Treatment
Different laser technologies are used in keratoconus treatment, and each is specially selected according to the patient’s eye structure. Here are the most commonly used types of keratoconus laser treatment and their details:
No-Touch Laser (TransPRK)
An innovative laser treatment method applied without direct contact with the cornea. The laser procedure is performed without any surgical instruments or physical contact with the eye surface. It is advantageous because it reduces the risk of infection and offers a painless, fast recovery process. The irregular curvature of the cornea is corrected with a low-energy laser applied to the eye surface.
Who is No-Touch Laser Suitable For? Patients with early and intermediate-stage keratoconus, those who feel discomfort using contact lenses, and patients who desire a minimally invasive procedure.
Topography-Guided PRK (Topoguided PRK)
The laser procedure is applied by custom mapping the corneal surface. It improves the refraction and focusing of light by correcting the surface curvature of the cornea. It is a highly effective method for keratoconus patients with irregular astigmatism. The detailed map of the cornea is taken with advanced topography devices, and the laser treatment is applied accordingly.
Who is Topography-Guided PRK Suitable For? Keratoconus patients with an irregular corneal surface, patients who want to increase the structural strength of the cornea, and those who have previously had intracorneal ring (Intacs) treatment and require additional correction.
Transepithelial PRK (Transepithelial Laser)
A surface laser treatment method applied by automatically removing the epithelial layer. Instead of manually scraping the corneal epithelial tissue, it is removed in a completely controlled manner with laser technology. It offers a more comfortable and faster recovery process compared to the traditional PRK method. This method, which focuses on the upper layer of the cornea, is particularly applicable in patients with mild and intermediate-stage keratoconus.
Who is Transepithelial PRK Suitable For? Patients with early-stage keratoconus, patients who desire a shorter recovery time, and those who do not want direct manual intervention on the eye surface.
| Keratoconus Treatment Type | Description | Who is it Suitable For? |
|---|---|---|
| No-Touch Laser (TransPRK) | The laser procedure is performed without any surgical instruments or physical contact with the eye surface, without direct contact with the cornea. The irregular curvature of the cornea is corrected with a low-energy laser. Reduces infection risk, offers a painless and fast recovery. | Patients with early and intermediate-stage keratoconus, those who feel discomfort using contact lenses, and patients who desire a minimally invasive procedure. |

| Transepithelial PRK (Transepithelial Laser) | A surface laser treatment method applied by automatically and controllably removing the epithelial layer with laser technology. Offers a more comfortable and faster recovery process compared to traditional PRK. Focuses on the upper layer of the cornea. | Patients with early-stage keratoconus, patients who desire a shorter recovery time, and those who do not want direct manual intervention on the eye surface. |
Recovery Process After Keratoconus Laser Treatment
There are some important points patients should pay attention to after laser treatment: Avoid rubbing the eyes – The corneal surface may become sensitive after the laser procedure. Use the eye drops prescribed by the doctor regularly – To reduce the risk of infection and speed up healing. Sensitivity to light may be experienced in the first few days – In this case, the use of sunglasses is recommended. The full recovery process usually takes 2 to 4 weeks – Slight blurriness or a stinging sensation in the eye is normal in the first few days.
Keratoconus Laser Treatment Prices
The cost of laser treatment may vary depending on the technology applied, the patient’s eye structure, and the selected clinic. The cost of keratoconus treatment varies depending on the method to be applied and the patient’s eye structure. There are price differences between laser treatments, contact lens applications, and surgical procedures. The most accurate step to get a clear price is to have an examination by an ophthalmologist.
Alternative Methods in Keratoconus Treatment
- Contact Lenses: Special rigid or hybrid lenses can be used to improve visual clarity in the early stages of the disease.
- Photorefractive Keratectomy (PRK): A laser treatment used in the mild and moderate stages of Keratoconus, which acts on the front surface of the eye.
- Eye Exercises and Vitamin Supplements: These do not directly halt the progression of the disease but may be beneficial for supporting overall eye health.
Post-Treatment Care for Keratoconus
Attention should be paid to certain points for the success of the post-treatment process:
- Maintain Eye Hygiene: Eye drops prescribed by the doctor should be used regularly to prevent the risk of infection.
- Limit Screen Time: Prolonged screen use can tire the eyes, so frequent breaks should be taken.
- Avoid Rubbing the Eyes: Eye rubbing can cause further damage to corneal tissue in keratoconus patients.
- Undergo Regular Eye Examinations: Contact with an ophthalmologist should be made at least once a year to monitor the treatment process and determine the need for additional interventions if necessary.
Keratoconus is a disease that can be controlled with early diagnosis and correct treatment methods. If you are experiencing symptoms such as blurred vision, light sensitivity, or corneal irregularity, it is recommended to get an eye examination for early intervention. Remember: the risk of the disease progressing increases the longer keratoconus treatment is delayed. You can achieve healthy vision with early diagnosis and appropriate treatment.
