Are you one of the Modesto residents struggling with nearsightedness, farsightedness, and astigmatism? If so, LASIK and Contoura Vision are the most renowned laser eye surgeries that solve vision problems. If you’re considering getting laser surgery in Modesto, you might wonder what the difference is between these popular eye surgery procedures, Contoura Vision and LASIK!
Being the most streamlined version of Lasik surgery in Modesto, Contoura Vision provides extraordinary results in improved visions. Contrarily, LASIK has been renowned for over 20 years for individuals having refractive errors, and it’s also a well-known eye surgery to lead a glass-free life.
Fundamental Differences Between LASIK and Contoura Vision
Below are the differences shown:
LASIK is the older type of laser surgery that has been around the corner for two decades, while Contoura Vision is an advanced form of LASIK.
- LASIK cures the pupillary axis to modify your vision, while Contoura Vision cures your visual axis, making the treatment effective.
- LASIK maps approximately 2000 points on the cornea to fix refractive errors. Contrarily, Contoura Vision maps 20,000 points, offering the sharpest and most crisp vision.
- LASIK provides a maximum of 6/6 vision, while Contoura Vision provides over 6/6 or 20/20 vision.
- The eye surgeon and the patient must pay extra attention during LASIK treatment, but Contoura Vision treatment remains unaffected by these problems.
- LASIK involves more corneal tissue loss, whereas Contoura loses a minor portion of the tissue.
- LASIK procedure involves blade usage, whereas the Contoura Vision process is bladeless, implying it’s painless.
How Does Conventional LASIK Eye Surgery Work?
In LASIK, ophthalmologists use precise measurements to proceed. Here, the eye surgeon will evaluate the following:
Vision Prescription
- Corneal Thickness
- Eye Health
Your eye doctor performs a tiny incision in your cornea and folds it back to reach deeper tissues. Now, the excimer lasers restructure the cornea based on the precise measurements done by your doctor. In conventional LASIK surgery, the surgeon decides the number of tissues to be pulled out and the angle at which the laser works. If performed by experienced eye doctors, LASIK is the most effective and safe process.
How Does Contoura Vision Surgery Work?
Every cornea possesses hills and valleys, and your corneas are as distinctive as your fingerprints. A Topolyzer is a measurement tool used by surgeons who use Contoura® to gauge that topographical region. That device can measure 22,000 points on the cornea. Your doctor’s guidance during laser surgery is derived from an algorithm that analyzes the data. The accurate measurements ensure the surgeon removes adequate tissue to modify your vision.
Comparing Eligibilities for Vision Surgery
One of the crucial differences between LASIK and Contoura is that while LASIK is FDA-approved to cure nearsightedness, astigmatism, and farsightedness, Contoura isn’t FDA-permitted for farsightedness. To be eligible for both surgeries, you should meet the below requirements:
- Age – 18 or higher.
- Eye health – Your eyes should be adequately healthy to get cured after surgery. Symptoms such as cataracts or glucoma might disqualify you from undergoing this surgery. Other conditions that make you ineligible are dilated pupils, thin corneas, and dehydrated eyes.
- Optimum health – You must not have an autoimmune disease, unrestricted diabetes, or any underlying health issue that might deter you from healing.
To be eligible for Contoura, your myopia prescription should be stable and measured at -8.0 diopters, and astigmatism should be measured at -3.0 diopters or less. On the other hand, LASIK’s prescription criteria include a stable myopia prescription that measures up to -12 diopters and, finally, a stable hyperopia and astigmatism prescription that measures up to 6 diopters.
