Undergoing Surgery for Myopia, it’s not just a matter of “going under the laser.” It all comes down to what happens before, during… and especially after. With the Zeiss VisuMax 800, refractive surgery becomes faster, more precise, and more comfortable—especially for nearsighted patients considering SMILE or LASIK. But let’s be clear: even with such an advanced platform, the outcome never depends on the machine alone. The preoperative evaluation, preparation in the days leading up to the procedure, and adherence to postoperative follow-up play a major role. If you’re looking for a simple, reliable guide free of unnecessary jargon, you’ve come to the right place.

Why the VisuMax 800 Is Changing the Surgical Experience for People with Myopia

The principle of the refractive surgery The goal remains the same: to reshape the cornea so that light focuses correctly on the retina. In cases of nearsightedness, the image forms in front of the retina. The laser therefore corrects this misalignment with great precision.

Where the VisuMax 800 represents a real breakthrough is in how this procedure is performed. Its high frequency significantly reduces treatment time: in SMILE, the lenticule can be cut in less than 10 seconds; in LASIK, creating the corneal flap takes about 5 to 7 seconds, depending on the settings. For the patient, this is not just a technical detail. Less time under the machine means less stress, less sensation of pressure, and less risk associated with small, involuntary eye movements.

Another key feature is the centering of the treatment. The OcuLign and Auliign systems were designed to better align the correction with the actual visual axis. In other words, the laser does not operate “at an approximate center.” It refines the alignment by accounting for cyclotorsion—the slight rotation of the eye that occurs between examinations performed while seated and the procedure performed while lying down.

For someone with nearsightedness—especially if they also have astigmatism—this precision in centering makes a huge difference. The correction becomes more consistent. And, frankly, the overall experience becomes much more comfortable.

SMILE or LASIK with VisuMax 800: What's the difference for a patient with myopia?

The VisuMax 800 does not replace refractive surgery techniques—it enhances them. Above all, it complements two major approaches.

  • The SMILE : The laser creates a flap within the cornea, which is then removed through a micro-incision. No corneal flap.
  • LASIK : The femtosecond laser creates a thin corneal flap, and then an excimer laser performs the vision correction.
  • The Choice It always depends on the cornea, the prescription, the ocular surface, and lifestyle.

SMILE often appeals to active patients, particularly because it better preserves corneal biomechanics and is frequently associated with less severe dry eye in the postoperative period. LASIK, on the other hand, remains a gold-standard technique offering very rapid visual recovery. In practice, there is no “best” technique for everyone. There is simply the one best suited to your eyes.

Before the procedure: Preparation involves more than just showing up on the day of the procedure

This is often where patients underestimate the importance of the preoperative process. However, proper preparation makes a big difference. It ensures accurate measurements, guides the choice of surgical technique, and improves postoperative comfort.

The Preoperative Evaluation: The Step That Really Makes the Difference

The evaluation is not meant to “quickly approve” a procedure. It is used to analyze the eye in detail. Corneal topography, pachymetry to measure corneal thickness, examination of the ocular surface, analysis of myopia stability, and a discussion of your expectations—all of these factors help determine whether SMILE, LASIK, PRK, or sometimes another solution is the most appropriate option.

That is also when we assess actual eligibility. Myopia that appears treatable on paper is not enough. A compatible cornea, stable refractive status, and an adequate tear film are required.

Lens prescription: Just a minor detail? Not at all.

Contact lenses temporarily alter the shape of the cornea. Continuing to wear them until the day before your evaluation carries the risk of obtaining inaccurate measurements. And in refractive surgery, an inaccurate measurement is never a trivial matter.

The period during which you must stop wearing contact lenses depends on the type of lenses you wear. It is determined precisely during your preoperative appointment. It is best to follow these instructions to the letter. For regular contact lens wearers, this is one of the most important steps to take before surgery.

Simple Instructions to Follow Before Surgery

You don't need a complicated ritual. However, certain habits really do make a difference in the days leading up to it:

  • Follow the instructions for removing the contact lenses within the specified time frame,
  • Please come without makeup on the day of the procedure,
  • arrange for someone to accompany the patient home,
  • Avoid alcohol and tobacco in the days leading up to the surgery,
  • Stay well-hydrated and get a good night's sleep the night before.

These are simple things, yes. But they help ensure accurate measurements, a more stable ocular surface, and a more comfortable recovery.

The Day of the Procedure: What Should You Really Expect?

The surgery is performed on an outpatient basis under local anesthesia using eye drops. No injections are required. No hospital stay is necessary. Generally, both eyes are treated one after the other, and the procedure is brief.

During the proceedings

Most patients are most apprehensive about the laser procedure itself. This is understandable. However, with the VisuMax 800, the procedure is very brief. The suction time—the moment when the handpiece is applied to the eye—is reduced, which significantly improves comfort. With LASIK, a temporary decrease in vision may occur for a few seconds during certain steps: this is normal and harmless, but it’s best to know this beforehand.

The procedure is considered painless. What’s actually most daunting is the technical setting and the fact that you have to remain still. Again, the brevity of the laser treatment helps a great deal.

Immediately after the surgery

After the procedure, your vision may be blurry or slightly hazy, and you may experience watery eyes or a sensation of having a speck of sand in your eye. This is to be expected. The first few hours are mainly for allowing your eye to recover at a leisurely pace. Do not drive. Have someone drive you home. And start the prescribed treatment right away.

Postoperative Follow-Up: What to Do and What to Avoid

It’s often after the surgery that the right questions come up. When can I go back to using screens? When can I exercise? When can I go back to work? Can I rub my eyes if they sting? Short answer: No, definitely not.

The First Few Days: Moderation and Discipline

The postoperative period with VisuMax 800 is designed to promote rapid recovery, but this does not mean you can let your guard down. After LASIK, vision often improves as early as the next day. After SMILE, vision generally improves within 2 to 4 days, sometimes even faster. However, this rapid improvement does not mean you can neglect precautions.

  • apply the prescribed eye drops at the indicated times,
  • Avoid rubbing your eyes,
  • limit exposure to dusty or smoky environments,
  • wear sunglasses when the light is bright,
  • Keep your follow-up appointments.

Resumption of activities: yes, but gradually

For office work, many patients return to their jobs within 24 to 72 hours, depending on the procedure and their visual comfort. Light exercise can resume shortly thereafter, followed by swimming and activities with a risk of eye trauma at a later date. Again, there’s no room for improvisation. The timeline depends on how well you heal.

Dry Eyes and Discomfort: What's Common, What Should Raise a Red Flag

Mild dryness, watery eyes, eye strain, or a gritty sensation are fairly common in the first few days. Artificial tears help a great deal. The SMILE procedure, in particular, is often appreciated for its minimally invasive nature and its milder impact on certain symptoms of postoperative dryness.

However, severe pain, a sudden loss of vision, significant redness, or worsening discomfort should never be ignored. In such cases, you should contact your healthcare team immediately.

What You Need to Know Before Getting Started

The Zeiss VisuMax 800 significantly improves the surgical experience for patients with myopia: faster treatment, more precise centering, greater comfort, and often a smooth recovery. But true success begins long before the operating room. A thorough evaluation, strict discontinuation of contact lenses, careful preparation, and meticulous postoperative follow-up—these are what make the difference. Are you wondering if your nearsightedness can be corrected with SMILE or LASIK, and under what conditions? The simplest way is to take stock during a personalized review, with recommendations tailored to your eyes, not to a theoretical profile.
