Which is best, Femto LASIK or Contoura Vision?
Laser vision correction has revolutionized the field of ophthalmology by providing a safe and effective means to correct refractive errors. With advancements in technology, there are now various types of laser vision correction procedures available, each with its own set of benefits and drawbacks.
Two popular options for laser vision correction are Femto Lasik and Contoura Vision. Both these procedures use advanced laser technology to reshape the cornea and correct vision. In this article, we will compare Femto Lasik and Contoura Vision to help readers understand the differences between these two procedures and make an informed decision about which one is best for them.
Femto Lasik, also known as Bladeless LASIK or All-Laser LASIK, is a type of laser vision correction surgery that uses femtosecond lasers to create a thin flap in the cornea. This flap is then lifted to allow for reshaping of the underlying corneal tissue using an excimer laser. Once the desired shape is achieved, the flap is placed back into its original position.
Femto Lasik is a quick and painless procedure, with most patients experiencing improved vision within 24 hours. It is a popular choice for correcting myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.
Femto Lasik is a two-step process that involves the creation of a corneal flap and the reshaping of the underlying tissue.
The first step of Femto Lasik involves creating a thin flap in the outermost layer of the cornea, called the epithelium. This flap is created using a femtosecond laser, which emits ultra-fast pulses of light that are one quadrillionth (10^-15) of a second in duration.
The laser creates tiny bubbles within the corneal tissue, separating the flap from the underlying tissue. This process is highly precise and does not cause any damage to the surrounding tissue.
Once the flap is created, it is lifted and folded back, exposing the underlying corneal tissue for reshaping.
The second step of Femto Lasik involves reshaping the corneal tissue using an excimer laser. This laser uses cool ultraviolet light to remove microscopic amounts of tissue from the cornea, according to a pre-determined treatment plan.
The amount of tissue removed is determined by the patient's prescription for nearsightedness, farsightedness or astigmatism. The goal is to create a more symmetrical and rounded cornea, improving the way light is focused onto the retina.
Once the tissue has been reshaped, the flap is carefully placed back into its original position, where it adheres naturally without the need for stitches.
Contoura Vision, also known as topography-guided LASIK, is a newer and more advanced version of traditional LASIK surgery. It uses topographic mapping technology to create a detailed map of the cornea, which is then used to guide the laser in reshaping the corneal tissue.
The main difference between Contoura Vision and Femto Lasik is that Contoura Vision takes into account individual variations in the shape and curvature of the cornea, whereas Femto Lasik follows a more standardized approach. This personalized treatment allows for better customization and correction of even minor irregularities in the cornea.
In addition, Contoura Vision has been shown to provide better visual outcomes and a higher level of patient satisfaction compared to traditional LASIK. It can also improve night vision and reduce glare and halos, which are common side effects of LASIK surgery.
Furthermore, Contoura Vision can be used for a wider range of refractive errors, including higher levels of myopia, hyperopia, and astigmatism.
However, not everyone is a suitable candidate for Contoura Vision. Patients with thin corneas or pre-existing conditions that may affect the healing process may not be eligible for this procedure. It is important to consult with a qualified ophthalmologist to determine if Contoura Vision is the right choice for you.
Femto Lasik uses femtosecond lasers to create the corneal flap and an excimer laser to reshape the corneal tissue. On the other hand, Contoura Vision uses topography-guided technology to map and guide the laser in reshaping the cornea.
As mentioned earlier, Contoura Vision offers a more personalized approach compared to Femto Lasik. This can result in better outcomes for patients with minor irregularities in their cornea.
Contoura Vision is also suitable for treating higher-order aberrations, which are tiny imperfections in the cornea that can affect vision. Femto Lasik may not be as effective in correcting these types of aberrations.
Both procedures have a quick recovery time, with most patients experiencing improved vision within 24 hours. However, Contoura Vision may have a slightly longer recovery time due to its more personalized approach.
The cost of Femto Lasik and Contoura Vision can vary depending on the individual patient's needs and the location where the procedure is performed. Generally, Contoura Vision tends to be slightly more expensive due to its advanced technology.
Both Femto Lasik and Contoura Vision are suitable for individuals with myopia, hyperopia, and astigmatism. However, Contoura Vision is also suitable for patients with minor irregularities in their corneas or higher-order aberrations that may not be effectively treated by Femto Lasik.
The decision between Femto Lasik and Contoura Vision ultimately depends on the individual's specific needs and preferences. Factors such as the severity of their refractive error, the presence of any corneal irregularities, and budget may all play a role in determining which procedure is best for them.
It is essential to consult with an experienced ophthalmologist who can evaluate your eyes and help you make an informed decision about which procedure is most suitable for your eyes.
