All-Laser (Bladeless) LASIK: Understanding Specific Risks, Complications, and Enhanced Safety

All surgery has possible complications and risks.  If you are considering the All-Laser LASIK surgery procedure using the IntraLase™ or another FDA-approved femtosecond laser to make the LASIK corneal flap instead of a blade), you should understand the risks.. 

The Bladeless Advantage: Understanding Risks Minimized and Unique Considerations

Considering All-Laser LASIK, widely known as Bladeless LASIK, means exploring a state-of-the-art approach to vision correction surgery. While sharing the core principle of reshaping the cornea with an excimer laser, the distinctive use of a femtosecond laser to create the corneal flap sets it apart from traditional LASIK. This technological difference influences its specific risk profile. As with any surgery, All-Laser LASIK carries potential risks and complications, but the method of flap creation can alter the probability or nature of certain issues. At Trusted LASIK Surgeons®, we stress that partnering with a highly qualified and experienced LASIK surgeon is the most effective way to navigate and minimize these risks.

An expert surgeon specializing in All-Laser LASIK procedures possesses the nuanced understanding required to determine if Bladeless LASIK is the optimal treatment for your unique eyes. They can discuss its specific safety profile, including risks unique to the femtosecond laser, potential reductions in mechanical flap complications, and compare it thoughtfully to alternatives like traditional LASIK, PRK, ASA, SMILE Eye Surgery, or various lens implants. Their proven experience with advanced laser technology is key to performing the surgery with the highest degree of precision and safety. Making an informed decision about All-Laser LASIK involves a clear understanding of its potential outcomes,

Important Disclaimer: This page focuses specifically on potential risks and complications associated with All-Laser (Bladeless) LASIK eye surgery, highlighting aspects potentially influenced by the use of the femtosecond laser for flap creation. While some risks overlap with traditional LASIK, the details here are tailored to the bladeless technique. Not every patient experiences these issues, and serious complications remain rare. The information here is not exhaustive, and your individual risks may vary. A thorough consultation with a qualified surgeon experienced in All-Laser LASIK is essential to understand these risks as they apply to you.  You should always confirm the specific procedures and technologies they offer and to schedule a consultation to discuss their candidacy and risksdirectly with the office of the LASIK surgeon you choose.

How Bladeless Technology Impacts the Risk Profile

The defining characteristic of All-Laser LASIK is the creation of the corneal flap using a femtosecond laser rather than a mechanical microkeratome blade. This fundamental difference alters the types of flap-related risks and potential outcomes:

• Enhanced Flap Precision: The femtosecond laser allows for highly precise control over the flap's dimensions (thickness, diameter, and hinge architecture). This precision can potentially reduce the incidence of irregular, incomplete, or "buttonhole" flaps sometimes associated with mechanical microkeratomes.
• Unique Laser-Specific Flap Phenomena: While minimizing certain mechanical risks, the femtosecond laser introduces phenomena related to the laser-tissue interaction. These can include the creation of a temporary opaque bubble layer (OBL) within the flap interface or, rarely, transient light sensitivity. Difficulty lifting the flap after laser creation is also a rare possibility.
• Impact on Corneal Nerves: Research continues to explore whether the precise, uniform nature of the femtosecond laser flap might affect corneal nerve severance and regeneration differently than a microkeratome, potentially influencing post-operative dry eye symptoms. While initial dry eye is common to both, nuances in its severity or duration might theoretically differ.

Beyond the flap creation, the excimer laser reshaping and the subsequent healing largely share potential outcomes and risks with traditional LASIK.

Potential Risks and Complications Following All-Laser (Bladeless) LASIK

While All-Laser LASIK is recognized as a safe and highly effective vision correction method, potential risks exist, some common to all LASIK and others with specific considerations related to the femtosecond laser.

Vision-Threatening or Potentially Serious Complications (Rare)

• Specific Laser Flap Complications: While typically safe, femtosecond laser flap creation can rarely result in issues like difficulty lifting the flap (due to an incomplete or inconsistent laser pass), a dense opaque bubble layer that temporarily obstructs vision, or unintended laser-tissue interaction effects.
• General Flap Issues: Despite laser precision, risks like microscopic debris or epithelial ingrowth (cells growing under the flap) can still occur, potentially requiring intervention. Very rare complications during flap creation or repositioning are possible.
• Corneal Ectasia: This rare but serious complication, where the cornea weakens and bulges, is a risk with any LASIK procedure (including All-Laser LASIK) if performed on an eye with insufficient corneal thickness or undetected corneal weakness (like forme fruste keratoconus). Rigorous pre-operative screening is vital regardless of flap method.
• Infection: Though uncommon, infection remains a serious potential complication after any eye surgery, including All-Laser LASIK. Severe infection is rare but can lead to vision loss.
• Keratoconus Progression: If a patient has underlying, undiagnosed keratoconus, All-Laser LASIK can potentially exacerbate the condition. Comprehensive screening is critical.
• Equipment Malfunction: Malfunction of either the femtosecond or excimer laser is a rare possibility.
• Other Rare Serious Issues: Extremely rare events like retinal detachment (especially in highly myopic eyes), significant hemorrhage, or severe, uncorrectable vision loss are possible in rare circumstances following any refractive surgery.

Non-Vision Threatening or Potentially Temporary Side Effects

• Post-LASIK Dry Eye: Experiencing dry eye symptoms is a common temporary side effect after All-Laser LASIK. The precise nerve disruption pattern from the femtosecond laser may influence healing, but noticeable dry eye is still expected. It typically improves with time and treatment, though can be chronic in rare cases.
• Visual Disturbances (Glare, Halos, Starbursts): Seeing glare, halos, or starbursts around lights, particularly at night, is a common potential temporary side effect after All-Laser LASIK. While often resolving, these symptoms can persist in some individuals.
• Temporary Light Sensitivity: Some patients report temporary photophobia (sensitivity to light) in the initial post-operative period, which may be more pronounced with femtosecond laser flap creation.
• Undercorrection, Overcorrection, or Induced Astigmatism: The excimer laser treatment may not result in the exact desired correction, leaving residual refractive error or creating new astigmatism, potentially requiring glasses, contacts, or an enhancement.
• Fluctuating Vision: Vision may fluctuate throughout the day in the initial healing phase.
• Regression: A portion of the vision correction may gradually decrease over time, requiring supplemental correction.
• Pain or Foreign Body Sensation: Some discomfort is typical immediately after surgery, usually resolving within a day or two.
• Need for Glasses/Contacts or Enhancement: Even after a successful procedure, corrective lenses may be needed for certain tasks, or a second laser procedure (enhancement) may be desired to fine-tune the result, provided sufficient corneal tissue remains.

It is crucial to discuss these and any other potential risks with your surgeon during your consultation, specifically addressing those related to the femtosecond laser and your individual eye characteristics.

Factors That May Influence Risk with All-Laser LASIK

Certain pre-existing conditions or ocular characteristics can influence the risk profile or candidacy for All-Laser LASIK. A thorough pre-operative evaluation is essential to identify these factors and determine if Bladeless LASIK is the safest and most effective option.

Factors that may impact risk or candidacy for All-Laser LASIK include those common to all LASIK procedures, as well as considerations specific to the femtosecond laser:

• Corneal Thickness and Shape: Insufficient corneal thickness or abnormal shape (including signs of keratoconus) remains the primary risk factor for post-LASIK ectasia, regardless of flap method.
• Severity of Refractive Error: Very high prescriptions may increase risks or limit predictability.
• Pre-existing Dry Eye Disease.
• Pupil Size: May influence the likelihood of persistent night vision symptoms.
• Systemic Health Conditions or Medications: Can affect healing.
• Certain Corneal Conditions: Beyond thickness/shape, conditions like active infections or severe scarring are contraindications.
• Ability to Lie Flat and Maintain Fixation: Necessary for the laser procedures.

Your surgeon, experienced in both femtosecond and excimer laser technologies, will perform detailed diagnostics to assess these factors and confirm your suitability for All-Laser LASIK.

The Critical Importance of a Thorough Pre-Operative Evaluation

The single most vital step in minimizing the risks associated with All-Laser (Bladeless) LASIK and optimizing your outcome is undergoing a comprehensive pre-operative eye examination by a highly qualified LASIK surgeon with extensive experience using femtosecond laser technology. This evaluation involves sophisticated diagnostic tests to:

• Precisely measure your refractive error and confirm its stability.
• Create detailed maps of your corneal shape and structure (topography and tomography) to rule out subtle corneal weaknesses or irregularities.
• Measure your corneal thickness (pachymetry) to ensure adequate tissue for a safe procedure.
• Evaluate your tear film and assess for dry eye disease.
• Measure your pupil size under different lighting.
• Check your overall eye health and review your medical history.

Based on this thorough assessment, your surgeon will determine if All-Laser LASIK is a safe and appropriate option and discuss the specific risks and benefits for your eyes. If it is not the ideal procedure, they can recommend a safer or potentially more effective alternative from the full range of vision correction options available.

Informed Consent Specific to All-Laser (Bladeless) LASIK

Prior to proceeding with All-Laser LASIK, you will participate in a detailed informed consent discussion with your surgeon. This process is your opportunity to fully understand the procedure, its expected visual results, alternative treatments, and the specific potential risks and complications, including those related to the femtosecond laser flap creation. You will review and sign a consent form acknowledging that you have received and understand this information.

While a general LASIK consent form covers many risks common to flap procedures, a discussion specific to All-Laser LASIK should address the nuances of the femtosecond laser technology used, such as the possibility of an opaque bubble layer or transient light sensitivity, in addition to the general risks of infection, ectasia, and refractive outcomes.

Informed Consent Form for All Laser LASIK Using the Intralase Laser (Sample)

This Informed Consent Form is for patients seeking vision correction of Nearsightedness (Myopia), Farsightedness (Hyperopia), and Astigmatism (Blurred Vision) through LASIK surgery using the IntraLase™ Technology.  

Indications and Procedure 

This information is being provided to you so that you can make an informed decision about K, or “all-laser” LASIK using the Intralase femtosecond laser. 

Traditional LASIK surgery involves two procedures: first, a microkeratome blade is used to create a flap on the cornea to expose the underlying tissue. After the flap is created, an excimer laser is used to reshape the eye by removing ultra-thin layers from the cornea in order to reduce farsightedness, nearsightedness, or astigmatism. Finally, the flap is returned to its original position, without sutures.

The All Laser LASIK surgery also involves two procedures. First, instead of a microkeratome blade, it uses the FDA-approved Intranasal laser to create a flap with laser energy. The IntraLase laser is capable of creating extremely precise flaps by producing tiny bubbles inside the cornea that are 1/10,000 of an inch in diameter. The laser beam cannot penetrate into the eye beyond the cornea. After the flap is created, an excimer laser is used to reshape the eye by removing ultra-thin layers from the cornea in order to reduce farsightedness, nearsightedness, or astigmatism. The flap is returned to its original position, without sutures.

Alternatives

All Laser or Bladeless LASIK is an elective procedure: there is no emergency condition or other reason that requires or demands that you have it performed. There are alternatives to this surgery: you could continue wearing contact lenses or glasses and have adequate visual acuity. There are also other types of refractive surgery, including LASIK with a microkeratome.

Risks and Complications

Bladeless LASIK using the IntraLase laser, like all surgery, presents some risks, many of which are listed below. You should also understand that there might be other risks not known to your doctor, which may become known later. Despite the best of care, complications and side effects may occur; should this happen in your case, the result might be affected even to the extent of making your vision worse. In giving my permission for IntraLASIK, I understand the following: The surgeon will use the FDA-approved IntraLase laser or another femtosecond laser to create a flap, and then an FDA-approved excimer laser to reshape the eye. The long-term risks and effects of All Laser LASIK are unknown. I have received no guarantee as to the success of my particular case. I understand that the following risks are associated with the procedure:

A. Vision-Threatening Complications

1. I understand that the femtosecond laser or the excimer laser could malfunction, requiring the procedure to be stopped before completion. Depending on the type of malfunction, this may or may not be accompanied by visual loss.

2. I understand that irregular healing of the flap could result in a distorted cornea. This would mean that glasses or contact lenses may not correct my vision to the level possible before undergoing bladeless LASIK. If this distortion in vision is severe, a partial or complete corneal transplant might be necessary to repair the cornea.

3. I understand that mild or severe infection is possible. Mild infection can usually be treated with antibiotics and usually does not lead to permanent visual loss. Severe infection, even if successfully treated with antibiotics, could lead to permanent scarring and loss of vision that may require corrective laser surgery or, if very severe, corneal transplantation or even loss of the eye.

4. I understand that I could develop keratoconus. Keratoconus is a degenerative corneal disease affecting vision that occurs in approximately 1/2000 in the general population. While there are several tests that suggest which patients might be at risk, this condition can develop in patients who have normal preoperative topography (a map of the cornea obtained before surgery) and pachymetry (corneal thickness measurement). Since keratoconus may occur on its own, there is no absolute test that will ensure a patient will not develop keratoconus following laser vision correction. Severe keratoconus may need to be treated with a corneal transplant while mild keratoconus can be corrected by glasses or contact lenses.

5. I understand that other very rare complications threatening vision include, but are not limited to, corneal swelling, corneal thinning (ectasia), appearance of “floaters” and retinal detachment, hemorrhage, venous and arterial blockage, cataract formation, total blindness, and even loss of my eye.

B. Non-Vision-Threatening Side Effects

1. I understand that there is a greater chance that the whites of my eyes may temporarily appear pink or red for several days to several weeks after surgery. This redness is more common with laser -created flaps than with microkeratome-created flaps.

2. I understand that my vision after surgery using the all laser LASIK technology may not be clear immediately and that I might not notice improvement for several days to several weeks.

3. I understand that there may be increased sensitivity to light, glare, and fluctuations in the sharpness of vision. I understand these conditions usually occur during the normal stabilization period of from one to three months, but they may also be permanent.

4. I understand that there is an increased risk of eye irritation related to drying of the corneal surface following the LASIK procedure. These symptoms may be temporary or, on rare occasions, permanent, and may require frequent application of artificial tears and/or closure of the tear duct openings in the eyelid.

5. I understand that an overcorrection or undercorrection could occur, causing me to become farsighted or nearsighted or increase my astigmatism and that this could be either permanent or treatable. If permanent, I may need to use glasses or contact lenses. I understand an overcorrection or undercorrection is more likely in people over the age of 40 years and may require the use of glasses for reading or for distance vision some or all of the time.

6. After refractive surgery, a certain number of patients experience glare, a “starbursting” or halo effect around lights, or other low-light vision problems that may interfere with the ability to drive at night or see well in dim light. Although there are several possible causes for these difficulties, the risk may be increased in patients with large pupils or high degrees of correction. For most patients, this is a temporary condition that diminishes with time or is correctable by wearing glasses at night or taking eye drops. For some patients, however, these visual problems are permanent. I understand that my vision may not seem as sharp at night as during the day and that I may need to wear glasses at night or take eye drops. I understand that it is not possible to predict whether I will experience these night vision or low light problems, and that I may permanently lose the ability to drive at night or function in dim light because of them. I understand that I should not drive unless my vision is adequate. These risks in relation to my particular pupil size and amount of correction have been discussed with me.

7. I understand that I may not get a full correction from my LASIK procedure and this may require future retreatment procedures, such as more laser treatment or the use of glasses or contact lenses.

8. I understand that there may be a “balance” problem between my two eyes after LASIK has been performed on one eye, but not the other. This phenomenon is called anisometropia. I understand this would cause eyestrain and make judging distance or depth perception more difficult.

9. I understand that, after LASIK, the eye may be more fragile to trauma from impact. Evidence has shown that, as with any scar, the corneal incision will not be as strong as the cornea originally was at that site. I understand that the treated eye, therefore, is somewhat more vulnerable to all varieties of injuries, at least for the first year following LASIK. I understand it would be advisable for me to wear protective eyewear when engaging in sports or other activities in which the possibility of a ball, projectile, elbow, fist, or other traumatizing object contacting the eye may be high.

10. I understand that there is a natural tendency of the eyelids to droop with age and that eye surgery may hasten this process.

11. I understand that there may be pain, irritation, or a foreign body sensation, particularly during the first 48 hours after surgery. I also understand that pain may be associated with complications such as infection.

12. I understand that temporary glasses either for distance or reading may be necessary while healing occurs and that more than one pair of glasses may be needed.

13. I understand that the long-term effects of LASIK are unknown and that unforeseen complications or side effects could possibly occur.

14. I understand that visual acuity I initially gain from LASIK could regress, and that my  vision may go partially back to a level that may additional surgery, or require glasses or contact lens use to see clearly.

15. I understand that the correction that I can expect to gain from LASIK may not be perfect. I understand that it is not realistic to expect that this procedure will result in perfect vision, at all times, under all circumstances, for the rest of my life. I understand I may need glasses to refine my vision for some purposes requiring fine detailed vision after some point in my life, and that this might occur soon after surgery or years later.

16. I understand that I may be given medication in conjunction with the procedure and that my eye may be patched afterward. I, therefore, understand that I must not drive the day of surgery and should not drive until I am certain that my vision is adequate for driving.

17. I understand that if I currently need reading glasses, I will still likely need reading glasses after this treatment. It is possible that dependence on reading glasses may increase or that reading glasses may be required at an earlier age if I have this surgery.

18. I understand that if I am over 40 years of age and have both eyes corrected for clear distance vision, I will need reading glasses for many close tasks. The strength of readers I will need may vary over the course of my healing. It is possible that my dependence on near correction may increase or decrease after surgery.

19. I understand that even 90% clarity of vision is still slightly blurry. Retreatment surgeries can be performed when vision is stable UNLESS it is unwise or unsafe. Retreatment surgery can be performed no sooner than three months after surgery, and for up to one year. Generally, the original flap can be re-lifted without creating a new flap. Rarely, a new flap may need to be created. A retreatment will only be considered if there is adequate corneal tissue. A retreatment will not be considered an option when it is deemed unwise or unsafe. In order to perform a retreatment surgery, there must be adequate tissue remaining. If there is inadequate tissue, it may not be possible to perform a retreatment. An assessment and consultation will be held with the surgeon at which time the benefits and risks of a retreatment surgery will be discussed.

20. I understand that, as with all types of surgery, there is a possibility of complications due to anesthesia, drug reactions, or other factors that may involve other parts of my body. I understand that, since it is impossible to state every complication that may occur as a result of any surgery, the list of complications in this form may not be complete.
