Laser eye surgery is an increasingly popular surgical procedure to improve vision and get rid of glasses or contact lenses.

However, before making an important decision like this, it is essential to be well informed. In this article we will see what are the 10 things you absolutely need to know about laser eye surgery, from understanding the different surgical techniques to evaluating the risks and benefits.

What does laser eye surgery consist of?

Laser eye surgery, an advanced laser eye surgery procedure, uses laser technique to correct visual defects such as myopia, astigmatism, hyperopia and presbyopia. This vision correction process uses cutting-edge laser technology to precisely reshape the cornea, significantly improving the patient's vision. To learn more, here is a study on the effectiveness of lasers .

Types of laser eye surgery: PRK, FEMTOLASIK AND RELEX SMILE

In refractive surgery , several advanced techniques are available, each with its specific characteristics and benefits. Here is a list that provides an overview of the main techniques:

  • PRK (Photorefractive Keratectomy)

PRK is a traditional method of refractive surgery that uses excimer laser technology . This technique is effective in correcting visual defects such as myopia, astigmatism and hyperopia. The procedure involves the removal of the superficial layer of the cornea, followed by correction using the laser. Recovery may take longer than other techniques, but long-term results are generally always positive.


The technique with FEMTOLASIK combines the femtosecond laser with excimer technology , offering precision and speed. This technique is known for its minimal invasiveness, recovery is rapid, it is suitable for correcting a wide range of visual defects and has a high success rate.


RELEX SMILE is the latest evolution in refractive surgery. This is a minimally invasive approach that uses exclusively the femtosecond laser . It offers faster healing and less post-operative discomfort than other techniques and is particularly effective in correcting myopia.

Each technique has its advantages and can be recommended based on the patient's specific needs. The Vista Vision eye clinic offers the possibility of evaluating, through renowned ophthalmologists who carry out a careful examination, which technique is most suitable for each patient.

The benefits of Laser Surgery

Laser surgery for the correction of visual defects presents a series of significant benefits :

  • Improved vision : The main goal of laser surgery is to improve vision. Often, this surgery allows you to obtain sharper and clearer vision.
  • Eliminating Glass Dependence : Many patients can say goodbye to glasses after laser surgery. This freedom from the need to wear corrective devices is one of the most appreciated benefits.
  • Elimination of contact lenses : For those who use contact lenses, laser surgery offers the possibility of completely eliminating the use of lenses, making daily life more comfortable.
  • Rapid recovery : Recovery after laser surgery is usually rapid, allowing patients to return to normal activities within a few days in most cases.
  • Minimal post-operative discomfort : Advanced techniques like RELEX SMILE offer an even smoother recovery with minimal post-operative discomfort.

The ideal candidates for laser eye surgery

Individuals who meet the eligibility criteria for laser treatment are people with stabilized visual defects , such as myopia, astigmatism and hyperopia. Typically, the minimum age requirement is approximately 18 years old and candidates must be free of serious eye conditions , ensuring adequate overall ocular health for treatment.

How to prepare for surgery

In the preparation phase for laser surgery, patients must undergo a comprehensive eye examination at specialized eye clinics to determine their suitability for the operation. It is essential to scrupulously adhere to medical indications, in particular regarding the temporary suspension of the use of contact lenses and the taking of specific medications.

What happens on the day of surgery

On the day of the operation, the entire process relating to the operation usually occurs quite quickly , through the use of local anaesthetics. This procedure is completed in a few minutes for each eye. Generally, patients can expect relatively short recovery times in most cases.

Recovery and post-surgery

Post-operative recovery depends on the specific technique used in the surgery. In general, patients can expect to return to their daily activities in a short period , usually a few days, by strictly adhering to post-operative care prescriptions. This is essential to ensure proper healing and to obtain the best results from the surgery.

What to expect in the long term

In terms of long-term effectiveness, many patients enjoy a substantial improvement in the quality of their vision, a result that often proves permanent . Despite the high effectiveness, some individuals may require additional adjustments to further optimize the vision correction performed. In certain cases, the use of glasses may remain necessary for specific activities, despite the generally positive long-term results of laser treatment.

The risks of laser eye surgery

Laser eye surgery, like any surgical procedure, carries a certain degree of risk regarding complications. Such complications can include infections, difficulty seeing at night, and dry eyes. It is important to note that these complications are generally rare and the safety of the surgery is a priority.

Costs of the intervention

Laser eye surgery costs can vary greatly depending on the technique used and the clinic selected . It is important to note that these costs may not be covered by health insurance, so it is essential to consider all financial factors before making a decision. Refractive surgery specialists can provide detailed information on costs and available payment options.


Laser eye surgery presents itself as an effective solution for improving vision. However, it is vitally important to conduct thorough research and consult highly qualified specialists before making a decision. Eye health is a precious commodity, and the choice to undergo this procedure should be carefully considered with the support of experienced professionals in the field.
