Vision-related problems are usually treated with LASIK which is one of the most common types of laser eye surgery performed by medical experts. The biggest reason why it is one of the most preferred options is because patients receive immediate results. 

What is a Femtosecond laser (FL)?

A type of laser that emits optical pulses with a duration well below 1 ps (ultrashort pulse) is known as a femtosecond laser. Usually, It is in the domain of femtoseconds (1 fs = 10^ -15 s) which is one quadrillionth of a second. The femtosecond laser also comes under the category of ultrafast lasers or ultrashort pulse lasers which also include picosecond lasers and other types of lasers. 

FL is extensively used in femtosecond laser cataract and refractive surgery. It is a surgical tool employed to prepare accurate, uniform, and predictable incisions in the cornea during the surgery.  

Where do you use Femtosecond Laser?

Femtosecond laser is typically used for refractive and cataract surgeries.

For the refractive surgery - this laser helps to flatten the cornea to treat nearsightedness, increasing the steepness of the cornea to correct farsightedness, and evening out an irregularly shaped cornea to treat astigmatism.

It is widely used for cataract surgery as well. The laser helps to break the cataract into multiple pieces and thus enables the surgeon for easier removal of the cataract.


According to several studies, the precise incision that a femtosecond laser provides is significantly better than a blade. Additionally, Femto laser treatment for the eye also causes less damage to the surrounding tissue as compared to the cuts made by a blade. So thus it is also called “bladeless” surgery. 

Because of the fewer complications during surgery, it has been observed that the patients are more likely to recover quickly. Apart from that, femtosecond laser cataract surgery technology provides more versatility and consistency during operations. The treatment also causes 106 times less damage in comparison to YAG laser treatment which is another most preferred type of ophthalmic laser. 

The most prominent benefit for eyes is the ability of the technology to provide even more precise astigmatism treatment via arcuate keratotomies, centration of the intraocular lens, and decreased ultrasound energy utilized during removal of the cataract. 

A femtosecond laser is also used for other ophthalmic procedures such as laser in situ keratomileuses (LASIK), penetrating keratoplasty, and other major types of corneal transplants. 


While conducting Femto laser treatment for the eye, the tissue is broken apart at the molecular level with the help of lasers rather than a cut with a sharp blade. The femtosecond laser disrupts stromal tissue through a process known as photoionization. With the help of this process, the targeted tissue is vaporized. The vaporized region creates a split where a cut would normally be made during the femto laser treatment for eyes.
