The duration of a refractive surgery laser is a crucial aspect to understand for anyone considering this type of treatment. At Clinique Néovision, we are committed to providing clear and detailed information to our patients. In this article, we explain the various factors that influence the time a laser refractive surgery procedure.
Types of laser refractive surgery
There are several laser refractive surgery techniques, each with its specific duration and procedural details.
Lasik
LASIK (Laser-Assisted in Situ Keratomileusis) is one of the most popular methods. This technique involves creating a corneal flap followed by reshaping the cornea with an excimer laser.
- Flap creation: The initial step is to create a small flap in the outer layer of the cornea, usually done with a femtosecond laser. This step generally takes a few minutes.
- Corneal reshaping: Next, an excimer laser is used to reshape the cornea. This step lasts between 5 to 10 minutes per eye, depending on the complexity of the case.
Overall, the complete LASIK procedure can take about 15 to 30 minutes, including preoperative and postoperative preparations.
PRK
PRK (Photorefractive Keratectomy) is another technique where the outer layer of the cornea is removed before using the excimer laser to reshape the cornea.
- Removal of the corneal epithelium: This phase takes a few minutes.
- Corneal reshaping: Similar to LASIK, this involves using an excimer laser for about 5 to 10 minutes.
The overall PRK operation can be completed within 20 to 40 minutes.
Preoperative steps
It's not just the surgical procedure itself that should be considered. The preoperative steps are also essential for the success of the intervention.
Initial consultation
Before the surgery, a thorough consultation is necessary to assess the patient's eligibility for laser refractive surgery. This consultation includes:
- Comprehensive eye medical exam
- Measurement of corneal thickness
- Vision quality analysis
This phase can take between 45 to 90 minutes.
Preparation on the day of the procedure
On the day of the surgery, certain preparations need to be done, such as applying anesthetic drops and other specific assessments of the patient's general health. This can add 30 to 60 minutes extra to the process.
Procedure progress
Clinique Néovision ensures a smooth and efficient flow for every laser refractive surgery procedure.
Setup
Upon arrival at the clinic, the patient will be comfortably settled in the surgery room. This setup usually takes 10 to 15 minutes.
Laser application
Depending on the chosen technique (LASIK or PRK), the laser usage time varies but remains relatively short, typically around 5 to 15 minutes per eye.
Immediate postoperative phase
After the surgical procedure, immediate care is necessary to ensure proper healing and to minimize the risk of complications.
Post-operation evaluation
Then, a brief assessment by the surgeon is done to ensure the procedure went smoothly. This quick diagnosis can add 15 to 30 minutes to the total time spent at the clinic.
Rest and monitoring
Patients are advised to stay under observation for about 30 to 60 minutes to monitor for any immediate adverse reactions.
Factors affecting the duration of the procedure
Several elements can influence the total time of thelaser refractive surgery procedure.
Case complexity
The complexity of the required eye correction plays a key role in determining the exact duration. For example:
- High myopia correction: The more severe the myopia, the longer the time needed to reshape the cornea.
- Presence of astigmatism: The combination of multiple vision disorders can slightly increase the procedure time.
Experience of the medical team
At Clinique Néovision, our experienced team not only ensures the safety of the procedure but also its timeliness. A well-trained team familiar with advanced technologies will significantly reduce the overall operation time.
Technologies involved
The technologies used during the operation vary depending on the available equipment and the protocols followed by the clinic.
Femtosecond laser
The femtosecond laser, primarily used to create the corneal flap in Lasik, is known for its precision and for reducing operation time compared to traditional mechanical methods.
Excimer laser
For corneal reshaping, excimer laser it is employed. Its speed and effectiveness allow each eye to be treated in just a few minutes.
Post-operative care and follow-up
Although this care is not directly included in the operation time, it is essential to mention it to provide a complete perspective on the process.
Follow-up visits
Regular appointments after surgery will help monitor healing progress and promptly address any potential issues.
- First visit: Usually scheduled the day after the procedure.
- Additional visits: Planned one week after, then one month later.
Adherence to post-operative instructions
Strictly following the instructions given by your surgeon is essential to ensure a fast and effective recovery.
