LASEK

The classic LASEK treatment is a safe, completely superficial laser procedure. At Visus Eye Clinic, we only offer this method in exceptional cases.

LASEK corrects vision defects without a flap or instruments on the eye. The laser first removes the superficial epithelium and then reshapes the cornea.

The treatment is performed exclusively at our main location in Rotterdam.

On the day of treatment, several patients have appointments at the same time. Upon arrival, we will review your information and perform additional measurements if necessary. Afterwards, you will receive a clear explanation of the treatment. This information is provided in a group setting.

On this page, you will find all the information about preparing for the treatment, the instructions you must follow, and the medications you will take afterward.

Before treatment

Preparation

Good preparation is essential for a safe and successful laser eye procedure. We have compiled an overview of all the important instructions you should follow leading up to your treatment. Please read these carefully:

Contact lenses

  • Soft lenses: do not wear for 14 days before treatment
  • Hard lenses: do not wear for 4 weeks before treatment
  • Night lenses: do not wear for 6 weeks before treatment

Pre-treatment care

  • Use omega 3-6-9 (fish) oil for better tear film stability (250mg, once a day, 2 weeks before treatment and up to 6 months after treatment)
  • No eye makeup on the day of treatment
  • Remove makeup the day before treatment and thoroughly clean your eyelids
  • Tinting eyelashes or applying false eyelashes? Plan this at least 1-2 weeks before the treatment.

On the day of the treatment

  • Arrive well-rested.
  • Do not use perfume, aftershave, or day cream
  • Wear comfortable clothing (no wool or loose-fiber clothing)
  • Keep in mind the operating room temperature is 18°C

What to bring

  • A companion (you cannot go home independently)
Your LASEK treatment What you can expect step by step

Important information in advance

  • Sedatives are not provided as standard, but are available upon request.
  • The total time spent in the clinic is 1,5-2 hours.
  • The treatment itself takes approximately 15 minutes.

Step 1 - Preparation
You will be given protective clothing (jacket, hat, and overshoes) and will receive an explanation of the procedure.

Step 2 - Anesthesia and Disinfection
The eye will be anesthetized with eye drops and then disinfected. An eyelid retractor will be used to keep the eye open. A sterile drape will be placed over your face, which you should not touch.

Step 3 - Preparing for the Laser Procedure
The laser will be set up, and you will be instructed to look at a fixation light. An eye tracker will accurately track your eye movements. If your eye moves too much, the laser will automatically stop.

Step 4 - Laser Treatment
The computer-controlled laser first removes the epithelial layer and then reshapes the cornea into the desired shape. If you have opted for wavefront treatment, additional optimization will take place that will take a few seconds longer. During the treatment, you may smell a burning odor.

Step 5 - Completion of the treatment
After the laser treatment, the ophthalmologist will rinse the cornea and apply a protective bandage lens (a soft, non-prescription contact lens). The underlying epithelium will need 3 to 4 days to heal.

Step 6 - Immediately after the treatment
You will go to a recovery room where you will receive the necessary medication. The staff will explain how to use this medication.

Step 7 - Aftercare
Three to four days after the treatment, you will return for your first check-up. During this appointment, the ophthalmologist or optometrist will remove the bandage lens and check the recovery of your eyes.

Please note:
A final suitability check will take place on the day of the treatment. Therefore, the treatment can still be canceled, modified, or rescheduled if it proves unsuitable for your situation or if the equipment does not meet the quality requirements. Visus Eye Clinic strives to keep such situations to a minimum.

After the treatment

Post-Treatment Instructions

After your LASEK treatment, it is important that you follow a number of lifestyle rules to ensure optimal recovery. Below you will find an overview of all instructions for the period after your treatment:

Immediately after the treatment

  • You may keep your eyes open or closed
  • Expect the following during the first few hours:
    • Watery eyes
    • Possible burning sensation or headache
    • Possible difficulty keeping your eyes open
    • Feeling as if something is in your eye
  • These symptoms usually disappear after 4-6 hours
  • You can use paracetamol if necessary

Hygiene and care

  • First 24 hours: Do not shower or wash your hair
  • Days 2-4: Showering is permitted, but do not get water in your eyes
  • Do not rub your eyes for at least 3 weeks
  • After 1 week: Regular makeup is permitted
  • After 3 weeks: Waterproof makeup is permitted
  • Wear protective goggles at night for the first week

Eye protection

  • Wear sunglasses for the first 2 weeks

    • smoky and dusty areas for 2 weeks
    • Sauna
    • Gardening
    • Activities Where dust/sand can get into the eyes
  • First month: no tanning beds

Important to know

  • What you see in the first few days is not indicative of the final result.
  • Blurred vision is normal and can last for several weeks.
  • People over 40 may need reading glasses.

If you have any questions or concerns, please contact the clinic at 0800 0088.

Recovery after treatment When can you expect the final result of your treatment?

Recovery after LASEK treatment is different for everyone. What you see in the first few days doesn't necessarily indicate the final result. Because the corneal surface needs to heal first, vision recovery with LASEK takes slightly longer than with other laser treatments. Most people can return to work after about 7 to 10 days. The final result is usually achieved after 4 to 6 months.

Immediately after treatment, slight swelling of the cornea almost always occurs. This can temporarily affect your vision:

  • With a previous minus prescription, you may see slightly more vision initially, which can make reading more difficult.
  • With a previous plus prescription, you may temporarily experience a slight decrease in vision, which means your distance vision is not yet optimal.

During the first few months, it is normal to experience:

  • Scattered light (glare or halo), especially in dim or dark conditions
  • A dry or tingling sensation
  • Variable visual acuity, especially with intensive viewing, such as driving or using a screen
  • Increased light sensitivity

These symptoms are part of the cornea's healing process and usually subside on their own. Additional artificial tears can temporarily stabilize and improve vision.

For a small percentage of patients, the final prescription does not fully meet expectations. If the prescription is demonstrably stable, we will discuss the possibility of additional correction. In practice, this rarely occurs within the first year.

Discharge letter for your GP
On the day of treatment, you will receive a discharge letter for your GP prior to the treatment. Please submit this letter at your next appointment so that your GP is aware of the treatment performed.

Aftercare

Medication

After laser eye surgery, you will use eye drops to support corneal healing. We will provide you with the necessary medications prescribed by your ophthalmologist. The clinic's pharmacy will then bill your health insurer for these.

If you need a repeat prescription later, you can easily request one via Repeat Prescription.

Please note! If your doctor advises medication that differs from what is described here, your doctor’s instructions are always leading.

Tips for using eye drops Read here how to use your eye drops correctly
  1. Wash your hands with soap and dry them thoroughly with a clean towel or paper.
  2. Sit down and hold the bottle of eye drops in your writing hand.
  3. With the fingers of your other hand, gently pull the lower eyelid downward to create a small pocket.
  4. Tilt your head back and look upward. If this is difficult, lie down instead.
  5. Rest the hand holding the bottle on the hand creating the pocket for extra stability.
  6. Hold the bottle above the eye, without touching the eye, eyelids, or eyelashes.
  7. Gently squeeze the bottle and allow one drop to fall into the pocket.
  8. Close your eye (without squeezing) and sit upright again.
  9. Gently press the tear duct at the inner corner of the eye for 1 minute. This prevents the drop from draining away too quickly through the nose or throat.
  10. Wash your hands again and dry them.
