With today's technology, advancements in medicine allow many health issues to be treated more effectively and comfortably. Eye diseases have been greatly impacted by these developments, and laser eye treatments have taken a prominent place. This method offers a great alternative for those who do not want to use glasses or contact lenses, with the potential to permanently correct vision problems. In this article, a detailed review of laser eye treatments will be provided, along with insights from the expertise of Op. Dr. Diclehan.
History of Laser Eye Treatments
Laser eye treatments first began in the 1980s and have since become safer, more effective, and patient-friendly. The first applications started with PRK (Photorefractive Keratectomy) and later diversified with techniques such as LASIK (Laser-Assisted In Situ Keratomileusis) and LASEK. Each method has different advantages and applications, but all aim to improve patients' quality of life.
In Turkey, laser eye treatments began to become widespread, especially in the early 2000s. Investments in this technology increased in eye hospitals and private clinics, allowing more patients to benefit. Specialists were trained, and services started being provided according to international standards.
Laser eye treatments involve reshaping the transparent front layer of the eye, called the cornea, to correct refractive errors (myopia, hyperopia, astigmatism). Excimer lasers are usually used in these procedures. The laser allows the corneal tissue to be shaped with micron-level precision.
Op. Dr. Diclehan emphasizes that these three primary vision problems can largely be corrected with laser eye treatments.
PRK is one of the oldest types of laser eye treatments. The epithelial layer of the cornea is removed, and the underlying tissue is reshaped with a laser. Recovery is slightly longer compared to other methods, but it is suitable for patients with thin corneas.
This is one of the most commonly used methods today. A flap is created on the cornea, the underlying tissue is reshaped with a laser, and the flap is replaced. This method stands out for its fast recovery and minimal pain. Op. Dr. Diclehan states that LASIK is the most frequently preferred method.
This method lies between PRK and LASIK. The epithelial layer is loosened with alcohol and lifted. After the laser treatment, the epithelium is placed back. Recovery is slightly faster than PRK.
This next-generation laser eye treatment involves removing a small lenticule through a tiny incision in the cornea. Performed without stitches or creating a flap, it is less invasive.
A detailed eye examination is essential before laser eye treatments. Corneal thickness, eye pressure, retina condition, and tear production are evaluated. Op. Dr. Diclehan emphasizes that each patient must be assessed individually, and laser should not be applied to unsuitable patients.
Eligibility criteria for laser treatment:
Patients are fully informed before surgery. Contact lens users are asked to stop wearing lenses a few weeks before the procedure. Eyes are sterilized and numbed with local anesthetic drops.
The operation usually lasts 10–15 minutes. Both eyes can be treated during the same session. Patients do not feel pain during the procedure. Eye movement is controlled with stabilizing devices.
Patients are discharged within a few hours. Mild stinging, tearing, and blurry vision may occur during the first days. Recovery time varies depending on the method used. Op. Dr. Diclehan notes that with LASIK, patients can usually return to normal life within 1–2 days.
Laser eye treatments are generally safe but carry some risks:
Op. Dr. Diclehan states that when performed by an experienced doctor, these risks are very low.
Most eyes treated with laser continue to see healthily for many years. In rare cases, prescriptions may progress again. Age-related issues like presbyopia may require different treatments.
No, patients do not feel pain during the procedure due to local anesthesia.
The total time for both eyes is 15–20 minutes.
It is generally permanent, but some patients may develop new vision problems with age.
Pregnant women, individuals with certain systemic diseases, or those with insufficient corneal thickness are not suitable candidates.
Usually not. In rare cases, glasses with very low prescription may be needed.
Laser eye treatments have revolutionized modern ophthalmology, providing an effective and reliable solution for individuals wishing to be free from glasses or lenses. Every patient should be assessed for suitability, and procedures must be performed by experienced doctors. Op. Dr. Diclehan, with years of expertise, delivers successful results in this field.
