What Is Excimer Laser?
Excimer laser is a modern eye surgery technology used to address refractive errors such as myopia, hyperopia, and astigmatism.
Excimer laser is a modern eye surgery technology used to address refractive errors such as myopia, hyperopia, and astigmatism.
Excimer laser is one of the modern laser technologies used to correct refractive errors of the eye. This method, which is commonly preferred for the surgical correction of refractive errors such as myopia, hyperopia, and astigmatism, refers to a laser procedure applied to the cornea, the front layer of the eye. The term excimer laser comes from the type of laser used and is derived from the words “excited dimer.”
This technology is frequently researched by individuals looking for an alternative to glasses or contact lenses. However, excimer laser does not promise a cure; it is considered a refractive eye surgery option only for individuals who meet certain conditions.
Excimer laser systems use a special ultraviolet light capable of shaping corneal tissue at a micron level. During the procedure, the laser aims to reshape the curvature of the cornea. In this way, light is intended to focus more accurately on the retina.
During the procedure, the laser operates without generating heat in the surrounding tissues. Thanks to this feature, excimer laser has been among the preferred technologies in eye surgery for many years. The application method and depth are planned according to the individual’s eye structure.
For each of these vision problems, excimer laser application is performed using different parameters. Therefore, personalized evaluation is of great importance.
When referring to excimer laser, it is not accurate to talk about a single method. With advancing technology, different application techniques have emerged. Each method has its own advantages and limitations.
In the LASIK method, a thin flap is created on the upper layer of the cornea. The laser application is performed beneath this flap. After the procedure, the flap is repositioned.
In the PRK method, no corneal flap is created. After the top layer is carefully removed, the laser is applied directly to the surface. This method may be considered an alternative for certain corneal structures.
No Touch laser, as the name suggests, is a type of excimer laser performed without direct contact with the eye. The laser shapes both the upper layer of the cornea and the underlying tissue in a single step.
Excimer laser is not suitable for everyone. Eligibility is determined as a result of a detailed eye examination. Factors such as age, stability of vision prescription, and corneal structure are taken into consideration during this process.
These criteria are provided for general informational purposes. The final decision is made based on an evaluation by a qualified specialist.
Before excimer laser, a comprehensive eye examination is performed. During this examination, measurements such as vision prescription, corneal mapping, and intraocular pressure are evaluated. Daily lifestyle habits of the individual may also be taken into account.
After the procedure, a certain recovery period is expected. This period may vary depending on the applied method. In the first days, symptoms such as blurred vision and light sensitivity may occur. These effects are generally temporary.
Excimer laser offers an option aimed at improving visual quality for suitable candidates. Its potential to reduce dependence on glasses or contact lenses is one of the most researched aspects of this method.
However, as with any surgical procedure, excimer laser also has limitations. It may not produce the same results for everyone and may not be suitable for some individuals. Therefore, having realistic expectations is important.
The laser application itself is usually completed within a few minutes. However, the total time spent at the clinic may be longer due to preparation and follow-up checks.
Excimer laser creates permanent changes in the corneal structure. However, age-related changes in the eyes may continue over time. This is considered a natural aspect of the procedure.
Excimer laser is a technological surgical option developed to address refractive errors of the eye. With its various methods and application techniques, it offers a broad range of evaluation possibilities. However, it is not suitable for everyone and requires a thorough assessment by a qualified specialist. Obtaining accurate and unbiased information about excimer laser is essential for making a well-informed decision.
