Where is the intelligence of femtosecond laser cataract?

-Isn't the femtosecond laser for myopia surgery?

-I heard that femtosecond laser is very smart for cataract surgery.

-Is Feibai a more high-end technique?

With the popularization of cataract surgery, more and more people have heard of professional terms such as "femtosecond" and "femtosecond laser-assisted cataract", and its personalized and precise characteristics have also won the love of many patients.

But many people are not very clear: what is a femtosecond? Where is the "intelligence" of femtosecond laser cataract surgery?

What are the cataract surgery methods?

Once you have cataracts, the lens inside the eye changes from clear to cloudy, which cannot be reversed and can only be treated with surgery. At present, the current mainstream method of cataract surgery is cataract phacoemulsification and intraocular lens implantation. With the development of technology, there is now a more advanced surgical method - femtosecond laser-assisted cataract surgery (referred to as "flying white"), which has attracted the attention of more cataract patients due to its "eye-catching".

Cataract phacoemulsification is performed by doctors using a scalpel and forceps to make surgical incisions and split cataracts, and then use a phacoemulsifier to emulsify the clouded lens, then aspirate it, and then implant the intraocular lens.

The principle of "flying white" is revealed

Femtosecond laser is a cold laser that operates in the form of pulses (1 femtosecond = tritrillionth of a second), which can accurately complete difficult steps such as incision making and lens segmentation without damaging surrounding tissues, and the error is controlled at the micron level.

Where is the "flying white" intelligence?

Femtosecond laser-assisted cataract surgery, also known as "knife-free" surgery, cataract surgery uses femtosecond laser, which is not only an auxiliary method, but also can replace the manual operation of our conventional surgical technology, change the traditional way of cataract surgery for a long time, and achieve a qualitative leap in accuracy and comfort.

Director Tan Yongchang, a cataract specialist, said

The entire femtosecond laser process is digitally controlled by the computer system, replacing the key steps such as transparent keratin incision, capsule removal, and nucleus splitting of traditional cataract surgery, and then the remaining surgical steps are completed through phacoemulsification.

The femtosecond laser is more "intelligent", which can accurately control the size and neutrality of the capsule tear, ensure the stability of the position of the intraocular lens, make a well-sealed corneal incision, and reduce the chance of intraocular infection; scanning the posterior capsule can predict the posterior capsule in time before cataract surgery, locate the depth of cleavage, and protect the posterior capsule.

The femtosecond laser accurately "blasts" the cataract nucleus, which can reduce the difficulty of surgery, reduce ultrasound energy, and increase safety for patients with dense old nuclei, white nucleus, and hard core for cataracts. Its application makes the surgical process smoother, which is less fearful and more comfortable for cataract patients during surgery, faster postoperative recovery, and better and faster vision recovery in the early postoperative period.

Everyone is suitable for "flying white"?

"Feibai" is so "intelligent" and loved by so many patients, is it suitable for everyone? In fact, the vast majority of cataract patients can choose, especially some complex and difficult cataract cases, and femtosecond laser has more advantages in treatment.

For patients who want to implant astigmatism-correcting intraocular lenses and multifocal intraocular lenses, femtosecond laser capsule removal can make the function of the intraocular lens more high-quality, and postoperative vision will be more comfortable and clear.
