In this article, we will explore the definition and procedure of bladeless LASIK, as well as the advantages it offers over traditional LASIK procedures. Additionally, we will delve into the different types of bladeless LASIK available on the market today.

1) Definition and Procedure of Bladeless LASIK:

Bladeless LASIK, also known as femto LASIK or all-laser LASIK, is an advanced refractive surgery procedure used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. Unlike traditional LASIK, which involves the use of a microkeratome blade to create a corneal flap, bladeless LASIK utilizes a femtosecond laser to create a precise and customizable corneal flap.

The procedure begins with the application of numbing eye drops to ensure the patient’s comfort. A suction ring is then placed on the eye to keep it steady during the corneal flap creation.

The femtosecond laser is then used to create microscopic bubbles within the cornea, which create a layer for the corneal flap. Once the flap is created, it is gently lifted and the underlying cornea is reshaped using an excimer laser.

Finally, the flap is carefully repositioned, without the need for stitches, and the healing process begins. 2) Advantages of Bladeless LASIK:

Bladeless LASIK offers several advantages over traditional LASIK procedures, making it an increasingly popular choice among patients and eye care professionals.

Some of these advantages include:

a) Predictable corneal flap thickness: With bladeless LASIK, the femtosecond laser creates a corneal flap of precise thickness, ensuring consistent and predictable outcomes. This accuracy leads to enhanced vision correction and reduces the risk of post-operative complications.

b) Decreased risk of corneal abrasions: The use of a femtosecond laser eliminates the need for a microkeratome blade, significantly reducing the risk of corneal abrasions during the procedure. This decreases discomfort and improves the overall safety of the surgery.

c) Decreased risk of induced astigmatism: Induced astigmatism is a potential side effect of LASIK surgery. However, bladeless LASIK minimizes the risk of induced astigmatism by providing a smoother and more precise corneal flap creation, resulting in improved visual outcomes.

d) Customized LASIK procedure: Bladeless LASIK allows for a fully customizable treatment, tailored to the unique characteristics of each patient’s eyes. This personalized approach maximizes the accuracy and effectiveness of the surgery, leading to superior visual outcomes.

e) Secure flap placement: The femtosecond laser creates a corneal flap that fits securely back into place, reducing the risk of flap dislocation. This gives patients added peace of mind and ensures a stable healing process.

Femtosecond laser technology has revolutionized the field of refractive surgery, particularly in the creation of corneal flaps.

In this section, we will explore the advantages of femtosecond laser flaps as well as potential complications that can arise from this technique. 3.1) Advantages of Femtosecond Laser Flaps:

a) More predictable flap thickness: One of the key advantages of femtosecond laser flaps is the ability to create flaps with consistent and predictable thickness.

In traditional LASIK procedures using a microkeratome, there can be variability in flap thickness due to factors such as suction pressure and surgeon technique. With femtosecond laser technology, the depth and dimensions of the flap are precisely controlled, resulting in a more predictable outcome.

b) Decreased risk of complications: Femtosecond laser flaps have been shown to have a lower risk of certain complications compared to flaps created with a microkeratome. By eliminating the variability associated with the manual blade, femtosecond laser technology minimizes the risk of irregular flaps, uneven edges, and buttonholes.

These factors contribute to improved visual outcomes and a reduced need for enhancement procedures. c) Thinner flap: Femtosecond laser technology allows for the creation of thinner flaps compared to those made with a microkeratome.

Thinner flaps preserve more of the corneal tissue, which can be beneficial for patients with thinner corneas or those who may need additional corneal surgeries in the future. d) Faster healing time: The precision of femtosecond laser flaps promotes faster healing compared to flaps created with a microkeratome.

The clean, smooth edges of femtosecond laser flaps allow for better apposition and adherence, leading to quicker epithelialization and reduced post-operative discomfort. 3.2) Potential Complications of Femtosecond Laser Flaps:

a) Partial flap: Although rare, a potential complication of femtosecond laser flap creation is a partial flap.

This occurs when the flap does not fully separate from the underlying cornea, leaving a portion still attached. Surgeons take precautionary measures to minimize the risk, such as confirming complete flap separation before proceeding with the surgery.

b) Flap dislocation: While uncommon, flap dislocation can occur following femtosecond laser flap creation. This typically happens within the first few days after surgery, and most instances can be resolved by repositioning the flap.

Surgeons ensure secure flap placement during the procedure, and patients are advised to avoid rubbing or touching their eyes during the healing process to minimize the risk of flap dislocation. c) Flap striae: Striae are small wrinkles or folds that can occur in the flap after LASIK surgery.

While they do not typically affect vision, severe striae may require additional intervention. Surgeons take precautions during the procedure to minimize this risk, such as ensuring adequate hydration of the cornea and careful flap repositioning.

d) Diffuse lamellar keratitis (DLK): DLK, also known as “sandpaper” or “inflammatory” syndrome, is an inflammatory reaction that can occur under the corneal flap. It is typically caused by the presence of foreign particles or epithelial cells trapped during flap creation.

Surgeons closely monitor patients for signs of DLK and promptly treat it if detected. e) Epithelial ingrowth: Epithelial cells can sometimes migrate beneath the corneal flap, leading to a condition called epithelial ingrowth.

While usually asymptomatic, this can cause visual disturbances or discomfort. Surgeons take precautions to minimize the risk of epithelial ingrowth, such as thorough irrigation of the corneal bed during the surgery.

f) Transient light sensitivity syndrome (TLSS): TLSS is a temporary sensitivity to light following LASIK surgery. It typically resolves within a few weeks but can cause discomfort during that time.

Surgeons may recommend the use of sunglasses or protective eyewear to minimize discomfort. 4) Cost of Bladeless LASIK:
