All you need to know about Bladeless Femto Laser Surgery

Our eyes are one of the most sensitive parts of our body. Dryness in the eyes, itchiness in the eyes, and other minor eye problems can be solved by visiting an eye doctor. However, unfortunately, eye ailments like glaucoma, retinal tears, cataracts, diabetic retinopathy, etc., can only be treated through eye surgery.

When anyone mentions surgery, the picture of needles and blades immediately flashes in front of our eyes. Right? Well, the good news is that you can now safely erase that picture from your memory since the technology used in eye surgeries has grown leaps & bounds in the last few years.

Bladeless Femto Laser Surgery, a combination of Lensx Femtosecond laser and live OCT-guided imaging, has provided eye surgeons with a high-precision approach to performing eye surgeries. With Femto Laser surgery, patients have the option of getting treated through highly safe and blade-free surgery. Bladeless Femto Laser surgery is a lot different from regular surgery, and this blog provides you with the essentials of the surgery.

What is Bladeless Femto Laser Surgery?

Bladeless Femto Laser Surgery is a form of eye surgery where all the surgery steps are the same as those followed in basic eye surgery, except that a computerized laser is used to perform eye surgery.

As no blades and needles are used in the surgery, the Bladeless FemtoLaser Surgery is much more precise than standard eye surgery. This surgical procedure is widely used to remove cataracts and LASIK (Laser-assisted in-situ Keratomileusis) surgery.

Femto Laser is also used to perform a blade-free laser vision correction procedure with no corneal flap requirement. This procedure is termed SMILE(Small Incision Lenticule Extraction). 

In this blog, we would limit Bladeless Femto Laser Surgery to cataracts and LASIK.

Femto Bladeless Laser Eye Procedure

In the surgical process, two ultramodern and ultra-precise laser systems are used so that the surgery can be executed with high precision.

Bladeless Femto LASIK Eye Surgery

This surgical procedure is carried out in two stages. The initial cut into the cornea is done using the laser, which creates a flap. The second laser makes use of an excimer system for reshaping the exposed corneal tissue (also called stroma).

In SMILE, there is no flap made and a small lenticular is fashioned depending on the eye power to be corrected. This is removed through a small 2mm incision

Shorter healing time, improved precision, and minimal chances of errors are some of the advantages of this Femto Bladeless Laser surgery.

Bladeless Femto Laser Cataract Surgery

Bladeless Femto Laser Surgery has modernized the complicated process of cataract surgery, as surgeons are no longer required to use needles and blades for the surgery.

This surgical procedure is more advanced in comparison to Bladeless LASIK surgery. Here are the series of steps involved in performing Bladeless Femto laser Cataract Surgery:

A camera/ultrasound/scanning device is used for gathering information about the lens by mapping the patient’s eye.

The data comprising live continuous 3D OCT (Optical Coherence Tomography)pictures is streamed to the computer screen, which in turn programs the laser. 

The laser is used for creating a precise opening in the cornea and the lens capsule. It also divides the cataract into smaller fragments 

The opening in the capsule is inserted with a pen-shaped phacoemulsification probe. The generated ultrasound waves break the cloudy center of the lens and emulsify it. The emulsified lens is taken out from the eye and replaced with an artificial lens. This step is the same for standard cataract surgery as well as Femto laser cataract surgery.

Advantages of Femto Laser

Here are some of the major advantages of Femto Laser surgery when compared to the traditional surgical procedure:

More Safety

In a standard LASIK or cataract surgery, needles and blades are used during the procedure. Whereas, in BladelessFemto Laser Surgery, a computer-controlled laser is used for performing the majority of the surgical steps. Hence, the chances of human error while performing the surgery are reduced, making the entire process safer. 

Improved Precision

 Automation is one of the guiding pillars of Bladeless Femto laser surgery. This results in highly precise and better results as compared to the traditional surgeries where everything is manual. 

Faster Results

Bladeless Femto Laser Surgery is performed in a relatively lesser time a majority of the steps are performed using Femto lasers. 

Faster recovery

As less energy is required for emulsifying the cataract and precise cuts are made by the Femto laser, visual recovery is faster than conventional surgery


Surgical automation or robotic surgery is instrumental in getting a more precise vision, which is not the case with standard surgery. Being the pioneer in laser treatment for eyes, CFS is the 1st in India to perform the Intralase blade-free Lasik & SMILE procedure.
