[Presbyopia/Cataract] Femtosecond Laser Cataract Surgery: Enhancing Stability and Accuracy

Precise and stable laser cataract surgery!

Hello. This is Gangnam Smile Eye Clinic, dedicated to restoring your happy smile and the joy of clear vision!

Laser cataract surgery is an advanced surgical method that replaces the manual steps performed by a surgeon with a femtosecond laser,

aiding in more precise vision correction and faster recovery.

With the introduction of the femtosecond laser, previously used in vision correction surgeries (all-laser LASIK, SMILE LASIK), into cataract surgery,

cataract surgery has become even more accurate and safer.

Shall we explore what a femtosecond laser is and how laser cataract surgery differs from traditional cataract surgery?

What is a Femtosecond Laser?

A femtosecond laser is a laser that emits extremely short pulses, lasting one quadrillionth of a second (10^-15 seconds).

It can perform micro-processing with very low energy, making it useful in ophthalmology for

vision correction surgeries (all-laser LASIK, SMILE LASIK) and cataract surgery.

1. Precise Corneal Incision

It performs 3D corneal incisions using real-time CT and a laser.

This creates a more three-dimensional and precise incision tunnel, increasing surgical stability.

Furthermore, since no suturing of the incision is required, recovery after surgery is faster.

2. Accurate Capsular Incision

Real-time CT allows for the identification of the boundaries of the lens capsule, which are invisible to the naked eye, enabling a capsular incision of precise size and shape.

This enhances the stability of the intraocular lens, leading to accurate vision correction and reducing side effects such as glare.

3. Lens Fragmentation in Desired Patterns

Previously, ultrasound energy was used to break up hard cataracts.

By using a laser to pre-fragment the lens into desired sizes and shapes,

ultrasound use can be reduced, minimizing tissue damage.

4. Corneal Astigmatism Correction

Corneal astigmatism can be simultaneously corrected through laser corneal incisions.

Compared to using a blade, the position, depth, and angle of the incision can be adjusted more precisely and smoothly.

Femtosecond laser cataract surgery allows for the stable insertion of an intraocular lens in the optimal position,

and promotes faster recovery by reducing tissue damage.

Additionally, it can improve the quality of vision through astigmatism correction that considers each individual's unique corneal shape.

Femtosecond laser cataract surgery is more useful for severe cataracts and severe astigmatism,

and the laser can replace parts that depend on the surgeon's skill, ensuring consistent results.

However, as the number of devices increases, the surgeon's skill in operating them cleanly and proficiently becomes crucial.

Even with advanced equipment, extensive experience from the operating surgeon is necessary to apply it smoothly in all situations.

Frequently Asked Questions

What is femtosecond laser cataract surgery?

Femtosecond laser cataract surgery is an advanced surgical method that replaces the manual steps performed by a surgeon with a femtosecond laser, aiding in more precise vision correction and faster recovery. The femtosecond laser, previously used in vision correction surgeries, has been introduced into cataract surgery, enhancing its accuracy and safety.

How does the femtosecond laser increase the safety and accuracy of surgery?

The femtosecond laser enhances surgical stability by enabling precise corneal incisions, accurate capsular incisions, and lens fragmentation in desired patterns. It utilizes real-time CT to precisely visualize areas invisible to the naked eye, assisting in the stable insertion of the intraocular lens.

Can astigmatism also be corrected with femtosecond laser cataract surgery?

Yes, it can. Femtosecond laser cataract surgery can simultaneously correct corneal astigmatism through laser corneal incisions. Compared to using a blade, the position, depth, and angle of the incision can be adjusted more precisely and smoothly, improving the quality of vision.

In what cases is femtosecond laser cataract surgery useful?

Femtosecond laser cataract surgery is more useful for severe cataracts and severe astigmatism. The laser can replace parts that depend on the surgeon's skill, ensuring consistent results.

Is the surgeon's experience still important when using advanced laser equipment?

Yes, it is important. As the number of advanced devices increases, the surgeon's skill in operating them cleanly and proficiently becomes crucial, and extensive experience is necessary to apply them smoothly in all situations to achieve optimal results.
