Laser eye procedures have gained popularity due to its effectiveness, speed of healing, and lack of post-operative problems. Since these technologies were first developed, additional advancements have occurred, such as the use of the femtosecond laser.
Femto LASIK is an acronym for femtosecond laser assisted in situ keratomileusis
LASIK is a type of laser eye surgery that utilizes femtosecond-assisted (Femto) laser in-situ keratomileusis (LASIK). This technique, in conjunction with others known as refractory surgery, is used to reshape the cornea of the eye in order to correct vision problems.
Keratomileusis, or the sculpting of the cornea to repair refractive defects, was invented in 1948Trusted Source using a tiny surgical instrument called the microkeratome.
This first technique, which included a mechanical instrument, was dubbed anterior lamellar keratoplasty (ALK). In the late 1980s and early 1990s, this procedure’s technology advanced.
In the early 1990s, the Femto laser enabled surgeons to construct the corneal flap needed in LASIK using a laser rather than a mechanical cutting instrument. The flap may be restored without sutures after surgery, allowing for faster recovery.
Laser surgery procedures
There are two primary forms of laser surgery utilized to remodel the cornea today:
- Photorefractive keratectomy (PRK): In this procedure, the cornea’s surface layers are removed, and the cornea is precisely shaped using lasers to correct refractive vision disorders. This procedure was pioneered in the 1980s.
- LASIK (laser in situ keratomileusis): This procedure is essentially a combination of the ALK and PRK methods of corneal reshaping. It entails the formation of a tiny flap that is raised during the reshaping of the cornea. At the conclusion of surgery, the flap is replaced and heals properly.
Who is the most qualified candidate?
To be considered a candidate for Femto LASIK from a Trusted Source, you must satisfy the following criteria:
- 18 years of age and older: Any sort of LASIK surgery is only authorized for use in adults.
- Consistent vision: You cannot undergo LASIK surgery if your glasses or contact lens prescription has changed in the last year, if you are using drugs that may impact your vision, or if you are experiencing hormonal changes that may influence your eyesight, such as nursing or diabetes.
- Good wound healing: You must be free of any diseases or drugs that may obstruct proper wound healing.
- Extremely thin cornea: Individuals with extremely thin corneas may face an increased risk of blindness following a LASIK procedure.
- Previous refractory surgeries: If you have had previous refractory surgeries or procedures, you may be ineligible for Femto or other types of LASIK surgery.
Conditions that might exclude you from undergoing surgery
Certain disorders or problems may need further conversation with your doctor or may exclude you from being a candidate for LASIK entirely. These include the following:
- dry eyes
- herpes simplex
- herpes zoster
What is the cost of Femto LASIK?
One disadvantage of refractive surgery is that it is considered elective and so not covered by most vision insurance policies.
However, you may be able to utilize a health savings account (HSA) or a flexible spending account (FSA) to cover the whole cost of the treatment or a part of it. Depending on your job or insurance provider, some insurance plans and LASIK facilities may also give savings.
LASIK surgery typically costs between $1,000 and $3,000 per eye. Femto LASIK is often more expensive than regular LASIK because to the advanced technologies employed. Additional considerations that may affect your cost include the following:
- your location
- the amount of vision correction required
- the surgeon’s ability.
Be cautious of “cheap” arrangements, which often include hidden expenses, use untrained surgeons, or depend on obsolete technology. Ensure that you inquire about the charges associated with your first meeting with your surgeon. Typical packages may cover the following:
- initial evaluation and testing
- all procedure-related charges
- post-procedure visits and drugs
- any necessary follow-up treatments.
How is Femto LASIK performed?
To comprehend Femto LASIK, it is necessary to comprehend how vision issues originate and how refractive surgery might assist. When the eye has difficulty bending and focusing light, refractive errors occur. There are many types of refractive errors.
- Myopia: Difficulty seeing objects in the distance, often known as nearsightedness. This issue develops when the cornea has a steeper curve, and refractive surgery corrects it by reducing the curvature of the cornea.
- Hyperopia: Difficulty seeing objects up close, often known as farsightedness. The cornea is too flat in this condition, and refractive surgery is done to enhance the cornea’s curvature.
- Astigmatism: Defects in the cornea’s shape. This problem is caused by the abnormal curvature of the cornea, and the irregular portions may be reshaped surgically.
- Presbyopia: Decreased flexibility of the eye as a result of aging. This is a condition that arises when the lens within the eye grows more rigid and loses its flexibility with age. While refractive surgery may be able to assist rectify this issue in certain situations, it may also exclude you from being a candidate.
Not all of these complications can be resolved by refractive surgery. Refractive surgery is only effective for correcting disorders that can be corrected by corneal reshaping.
When refractive surgery is done to treat these issues, an incision on the surface of the eye is created and the cornea is reshaped using a laser.
Femto LASIK procedure
The following stages will occur on the day of surgery:
- You will be escorted to a procedure room where you will be seated on a reclining chair.
- You’ll lay on your back in front of a laser system and a computer monitor.
- Your eyes will be numbed using numbing drops.
- During the process, an eye speculum will be utilized to keep your eyelids open.
- Suction is then applied using a suction ring centered over the pupil.
- A glass lens to stabilize the globe of the eye and flatten the cornea. • Once the laser has focused on the surgical region, your surgeon begins the procedure.
- The laser pulses to form a flap on the cornea’s surface, allowing suction to be released.
- After peeling back the flap, a precision excimer laser utilizes ultraviolet light to remodel the cornea to correct your issue.
- During this stage of the process, you may hear a ticking sound or smell something burning.
- In Femto LASIK, the flap is replaced after reshaping.
- Without sutures, the flap will heal in situ.
Each eye should take no more than 30 minutes to complete the treatment. Assure that you have someone to drive you home after the surgery.
