Advantages and Disadvantages of FEMTO Second LASER i.e. Bladeless LASIK Surgery

The procedure known as bladeless surgery, all-laser LASIK, or Femto Laser Surgery has been gaining popularity due to its innovative approach to LASIK surgery. The term 'FEMTO second' refers to the extremely short pulse used in the fabrication of the corneal flap. In this article, we will explore the advantages and disadvantages of this advanced technique based on interactions with ophthalmologists and observations of operating rooms.

Understanding Femtosecond Laser Surgery

Femtosecond laser technology is now widely accepted as revolutionizing the LASIK process by introducing bladeless methods. Unlike the older methods where a microkeratome (a blade) is used to create a flap, the Femto second LASIK employs an extremely short pulse—femtoseconds—to nucleate a bubble inside the cornea. This process creates a circular flap that can be precisely peeled off, ensuring uniform thickness and minimizing the risk of complications.

Advantages of Femtosecond Laser Surgery

1. More Predictable Corneal Flap Thickness

The accuracy of the Femtosecond laser in creating a perfect flap results in a higher predictability of flap thickness. This is crucial for ensuring consistent and reliable outcomes, which is a significant advantage over blade-based methods that can introduce variability.

2. Decreased Risk of Corneal Abrasions

The risk of corneal abrasions during surgery is significantly reduced with Femtosecond laser surgery. The bladeless process eliminates the potential for injuries that can occur during the flap creation process, making the procedure safer for patients.

3. Decreased Risk of Induced Astigmatism

Induced astigmatism is a common complication in LASIK surgeries. The precision of the Femtosecond laser in creating the flap ensures that the risk of developing this condition is minimized. This is a crucial advantage, as astigmatism can severely impact vision quality.

Disadvantages of Femtosecond Laser Surgery

1. Higher Cost

A significant challenge with Femtosecond laser surgery is its associated cost. The Femto LDV typically costs upwards of $400,000, and additional costs for consumables add to the overall expense. On average, a pack used in the procedure can cost around $250. Although blade flap procedures also require a similar kit, the additional cost of the equipment and time saved in both the surgeon and operating room (OR) time contribute to an increased overall cost per procedure. This is an important consideration, especially since LASIK is often an elective surgery not fully covered by health insurance.

2. Longer Surgery Time

The Femtosecond laser process is more time-consuming than the traditional blade-based LASIK. The precise creation of the corneal flap through the Femtosecond laser takes additional time, even though modern technology has streamlined this process. This increased time can be a drawback for some patients, particularly those sensitive to extended durations in the operating room.

Conclusion

In summary, while Femtosecond laser surgery offers numerous advantages in terms of precision, safety, and predictability, it also comes with higher costs and longer surgery times. Patients considering this procedure should carefully weigh these factors against their individual needs and circumstances. It is also crucial to consult with an experienced ophthalmologist to ensure that the procedure is the best option for their specific vision issues and overall health.
