Femto LASIK Surgery: Function, Types, Benefits, and Procedure

Femtosecond laser cataract surgery, often known as Femto LASIK, is a cutting-edge advancement in the field of refractive surgery for your eyes. Femtosecond LASIK offers a precise and customized technique. It has changed the lives of innumerable people who have been wearing glasses and contact lenses for too long.

Definition of Femto LASIK

Femto LASIK procedure is often referred to as bladeless, all-laser, or blade-free LASIK. The surgeon uses two different types of lasers, to perform the eyesight correction surgery. The excimer laser is used to restructure the stroma or underlying corneal tissue after the very advanced femtosecond laser has created a thin, precise cornea. The flap is subsequently changed without blades to guarantee unobstructed viewing.

During Femtosecond laser cataract surgery, the Femto-second laser is used to create the corneal flap. With significantly lower chances of complications during the process and much thinner flaps, the Lasik procedure is now even safer. It increases the likelihood that the cornea will become more stable over time.

What are the Types of Laser Cataract Surgeries??

The cornea can be reshaped using one of two primary types of laser surgeries:

Photorefractive keratectomy (PRK): This procedure uses lasers to shape the cornea to treat refractory vision issues precisely. It involves removing the outer layers of the cornea. The 1980s saw the first use of this technique.

Laser in-situ keratomileusis (LASIK): LASIK eye surgery is a useful technique to correct refractive errors. ALK and PRK techniques are essentially combined to reshape the cornea. A little flap is created and lifted during the corneal reshaping process. The flap is replaced after surgery, and it takes time for it to heal.

What are the Advantages of Femto Laser Cataract Surgery?

There are many advantages of Femto laser cataract surgery. Some of them are:

Increased safety: Lasik significantly lowers the risk of issues that could arise from utilizing a corneal flap. Additionally, the chance of infection and inflammation is decreased. Retreatment rates are lowered since there is a more excellent treatable surface for improved stability.

Thinner flap: The corneal flap made possible by the Femto LASIK procedure is so thin and evenly sliced that problems are essentially non-existent. Because more corneal tissue is left behind with these more minor flaps, there is a chance to rectify higher refractive faults as well as promote long-term corneal stability.

Even flap thickness: The surgeon is aware of the form, thickness, dimensions, and capacity of each flap before utilizing the Femto-Lasik. When thinking about treatment for higher refractive errors, this is a crucial concern. A surgeon employing a microkeratome can only see the final appearance of the flap after the incision is completed.

Other advantages: Femto-Lasik laser eye surgery does not require precise measuring of the eyes. Your eyes will develop considerably faster, and you will heal more swiftly. The visual outcomes are superb. The Femto-Lasik laser applies less pressure to the eye during the process. This implies that the patient will feel very minimal pain.

Who is eligible for the Femto LASIK Procedure?

Femto LASIK procedure may be the best option as a vision correction surgery. Depending on the candidate's degree of near-sightedness, the surgeon will decide if they are eligible for surgery.

The following three factors decide if you are an appropriate candidate for Femto LASIK:

• The person has to be at least 18 years old. It suggests that adult patients are the only ones who can get surgery.
• Femto LASIK is not a suitable choice for people whose refractive powers fluctuate. Hence, the individual's vision needs to be steady.
• The person must have strong healing powers.
• Blindness is more likely to result from Femto LASIK surgery in patients with thin corneas. The person has to have suitable corneal thickness.?
• An individual is not eligible for Femto LASIK procedure if they have previously undergone refractive surgery.

How does Femto LASIK Work?

Femtosecond laser cataract surgery employs corneal reshaping and internal lens construction in the following cases:

Myopia:

Laser surgery flattens the corneal curvature by removing tissue from the center cornea. It lowers the focusing ability of your eyes. A more extended look or a steep corneal curve causes images to focus in front of the retina. They are then pushed closer to the retina after Femto LASIK surgery.

Astigmatism:

Femto LASIK surgery can correct astigmatism. The cornea is once more flattened to improve symmetry, but only along the steeper corneal meridian. As a result of this process, images are sharply focused on the retina instead of being warped by light dispersing through an irregularly shaped cornea.

Hyperopia:

Refractive surgery methods aim to create a steeper cornea to improve your eye's ability to focus. After surgery, images that are focused beyond the retina because of a flat cornea or short eye will be brought closer to, or directly onto, the retina.

Step-by-step procedure for Femto LASIK

Pre-Op Preparation:

The ophthalmologist conducts examinations to map the cornea and program the laser systems. Pupils may be dilated.

In the Operating Room on Surgery Day:

1. Anaesthetic drops numb the eye for comfort.
2. The patient lies down under the laser system, and chin/forehead rests are used to steady the head.
3. The doctor uses a speculum to keep the eyelids open, along with a suction ring centering on the eye to enable stable laser engagement.
4. The surgeon appliances the globe of the eye with a lens for adequate corneal exposure to the lasers.
5. The Femtosecond laser system is positioned and activated on the corneal surface.
6. Computer-guided laser pulses create a thin flap on the corneal surface within a few seconds via photo disruption.
7. On completion of flap creation, the surgeon disables suction allowing laser disengagement.
8. The corneal flap is gently lifted and folded aside using micro-instruments to expose the inner stroma.?
9. Now, the patient is precisely aligned under the excimer laser, which ablates the stromal tissue in a pre-programmed pattern.
10. An itchy/burning sensation may occur because of thin corneal layers vaporized by excellent excimer laser beams.
11. Once stromal modification is achieved, the corneal flap is smoothly repositioned back into location. ?
12. The flap seals itself within minutes, allowing rapid visual recovery as the epithelium quickly heals without sutures over the optimized corneal architecture.

The entire procedure takes about 30 minutes of actual laser treatment time per eye.

Post-Op Care:

Eye drops, rest, avoiding eye rubbing, and night eye shields. Healing continues over weeks.

What is the recovery time after Femto LASIK surgery?

You may return home the day after Femto LASIK surgery. You'll often resume your regular activities in a day or two. However, it can take you a bit longer to recover fully. You'll follow a standard post-operative recovery course under your care and proceed without issues.

Day of the Surgery

Your eyes are sensitive because a laser was just pointed at them. You could feel uncomfortable in the early hours following surgery. In addition to painkillers, your doctor might prescribe eye drops to keep your eyes moist and free of infections.

24 Hours After Femto LASIK

Your eyes are starting to heal, although they could still hurt and feel sensitive. During this stage, inflammation is typical. After a Femto LASIK operation, you should take a few days off from work. This will allow any post-operative vision problems to go away for you. This encompasses haloes and glares surrounding lights.

1-2 Weeks After Surgery

Although the flap formed by Femto LASIK is beginning to heal, your eyes still require careful attention to guarantee optimal healing. At this time, make sure you keep your doctor's appointments.

1 Month After Surgery

Your eyes are still recovering. You may have clear, sharp eyesight now that the swelling has subsided. However, the tissue surrounding your flap is still mending and painful.

3-6 Months After Surgery

You probably have a clear vision at this stage. You might not experience any side effects or pain while your eyes are still recovering. Maintain your attendance at all follow-up appointments with your physician and follow the instructions provided by your surgical care team for your recovery.
