What Is the Difference Between LASIK and LASEK?

When considering laser vision correction procedures, LASIK and LASEK are two of the most popular options. Both eye surgeries aim to correct common vision problems like nearsightedness, farsightedness, and astigmatism. While they share the goal of enhancing vision clarity, they differ in their approaches and suitability for different eye conditions.

Understanding these differences can help you determine which procedure aligns best with your vision correction needs. This guide delves into the essential distinctions between LASIK and LASEK, exploring their respective benefits and limitations, to help you make an informed decision about your eye care journey.

Detailed Comparison

This comprehensive comparison between LASIK and LASEK provides insights into each laser eye surgery specifics:

	LASIK	LASEK
Procedure	Involves creating, folding back, and then repositioning a corneal flap to reshape the cornea with a laser	The cornea’s epithelial (surface) layer is loosened using alcohol, moved aside, reshaped with a laser, and then repositioned
Recovery Time	Typically quicker, with most patients seeing vision improvement within a day	Generally takes longer than LASIK, with up to a week or more for full eye healing and vision stabilization
Pain During Recovery	Usually minimal discomfort	More discomfort due to the healing of the corneal surface layer
Risk of Complications	Potential for flap complications, though rare	No risk of flap complications but may have a slightly higher risk of corneal haze that is usually transient
Best Candidates	Less ideal for individuals with thin, irregular-shaped corneas, or those in combat sports	More appropriate for people with thin corneas, dry eye history, or active in combat sports, as it does not involve creating a flap
Side Effects (Usually Temporary)	Some patients experience dry which is usually transient, rare corneal flap dislocation, light sensitivity, bruising, scratchy sensation, and eye pain	Involves discomfort, blurry vision (stromal haze), eye pain during recovery, slower healing than LASIK
Cost	Approximately $3,000 to $6,000 for both eyes
Effectiveness for Vision Correction	Recognized as safe and effective methods for vision correction
Treated Conditions	Effective for nearsightedness, farsightedness, and astigmatism
Number of Treatments	Typically a single session is sufficient

#1. LASEK vs. LASIK Surgeries

LASIK Procedure:

LASIK (Laser-Assisted In Situ Keratomileusis) utilizes a femtosecond laser to create a thin corneal flap.
The flap is lifted to allow the excimer laser to reshape the underlying corneal tissue.
Post-laser treatment, the flap is repositioned, sealing naturally without stitches.

LASEK Procedure:

Considered among surface laser treatments, LASEK doesn’t involve creating a corneal flap.
The outer corneal layer is loosened using an alcohol solution and gently moved aside.
The excimer laser then reshapes the stroma, similar to the LASIK eye surgery process.
The epithelial layer is repositioned and secured with a temporary contact lens bandage.

#2. LASIK vs. LASEK: Recovery Time

LASIK vs. LASEK: Recovery Time

LASIK:

Known for its quick recovery as the corneal flap heals within 24 hours.
Patients often experience clear vision within a day and can quickly resume most activities.

LASEK:

Involves a slightly longer recovery period due to the regeneration of the outer corneal layer.
Typically takes several days for initial healing and a few weeks for complete visual stabilization.
A protective contact lens is worn during the initial healing phase.

#3. LASEK vs. LASIK Surgery: Pain and Discomfort

Patients undergoing LASIK generally experience less discomfort compared to those having LASEK surgery. LASEK, due to the removal and reattachment of the corneal layer, often leads to more discomfort and a longer healing process.

#4. LASIK and LASEK: Risk of Complications

Both surgeries are considered safe, but they have different risks. LASIK may involve complications related to the corneal flap, such as dislocation ( rare ) or inflammation ( uncommon and short-lived ). LASEK, being a surface treatment, eliminates the risks associated with a flap but may have a higher likelihood of postoperative haze.

#5. LASIK vs. LASEK Eye Surgery: Suitability

LASIK is often preferred for individuals with thicker corneas, as it requires creating a flap. LASEK, on the other hand, is more suitable for those with thin corneas or lifestyles involving combat sports, as it does not involve flap creation. However, an ophthalmologist can help determine the suitability for either procedure based on a thorough examination of the patient’s eyes.

LASEK vs. LASIK Pros and Cons

Here, we outline the advantages and disadvantages of each procedure to assist in your decision-making process.

Advantages of LASIK Treatment:

Typically features a rapid healing period of about 24 hours, with vision clarity often improving within hours post-surgery.
Commonly results in 20/40 vision or better.
Classified as a minimally invasive approach.
Generally causes only mild discomfort, which subsides swiftly.
Lower incidence of complications such as hazy vision due to preserved corneal integrity.

Disadvantages of LASIK Surgery:

Dry eyes are a not uncommon early side effect that usually resolves by 3 months.
Potential for complications related to the corneal flap.
Risk of flap displacement due to direct trauma to the eye.

Advantages of LASEK Eye Treatment:

Suitable for individuals with thin corneas.
Lower occurrence of dry eyes compared to LASIK.
Eliminates risks associated with flap complications and excessive removal of the cornea’s outer layer.
Vision improvement to 20/40 or better is common.
Involves placing a bandage contact lens for protection during the healing process.

Disadvantages of LASEK Eye Surgery:

Longer recovery time, usually taking three to five days, with a gradual improvement in vision.
Pain and discomfort may persist for a few days post-surgery.
Potential for compromised corneal structure leading to haze.

Understanding LASIK vs. LASEK Costs

Prospective patients will find that the prices for both procedures often fall within a similar range, typically between $3,000 and $6,000 for both eyes. However, it’s common to see LASIK surgery priced slightly higher than LASEK. This difference in cost is mainly due to LASIK requiring two lasers – one for creating the flap and another for the reshaping of the cornea – whereas LASEK involves a single laser for the reshaping process.

Factors influencing the cost of both LASIK and LASEK include:

Geographic Location: Costs can vary based on the local market, with higher prices often seen in larger cities.
Surgeon’s Expertise: The skill level and experience of the surgeon can impact the price.
Technology Used: The choice of technology, such as all-laser LASIK or the use of a microkeratome blade, can affect the cost.
Degree of Vision Correction Needed: More complex vision problems might require more extensive treatment, potentially raising the cost.

It’s important to note that both LASIK and LASEK are typically considered elective procedures and aren’t usually covered by standard health insurance plans. However, they’re eligible for medical expenses for flexible spending arrangements (FSAs) and health savings accounts (HSAs), providing an avenue for patients to manage their costs.
