What will be the corneal thickness after LASIK?
The ultrasound waves measure the thickness of your cornea. Surgeons like a patient to have 250 microns of corneal tissue remaining after LASIK. This means that after the flap has been made and the prescription is applied, you should have that much left. Most surgeons make a flap that’s about 160 microns.
How much tissue does LASIK remove?
On average, we remove 12 to 14 microns of tissue for each diopter of prescription power. After this corneal tissue is removed, patients should have at least 250 microns of corneal tissue remaining. Any less than this would lead to an increased risk of surgical complications.
What is a good corneal thickness?
about 540 microns
Normal corneal thickness is about 540 microns (half of a millimeter). Thickness is checked with a handheld ultrasound device called a pachymeter.
Is flap created in Contoura vision?
Flap Free Approach: Contoura surgery requires a flap. It also does not offer a minimally invasive flap free approach like SMILE.
How does Contoura LASIK work?
With Contoura Vision, the contours of the cornea generated by the computer analysis are programmed into a specially designed laser used for this procedure. At least 22,000 points of the cornea are mapped. An individualized treatment plan is made, and the laser applies this treatment to the cornea.
What is EPI Contoura?
Epi Contoura / Streamlight Laser is special advanced technique of laser specs removal used in patients not eligible for Contoura Vision specially in those having thin corneas. Epi Contoura procedure is 100\% blade-free, 100\% cut free, 100\% flap free, 100\% touch less.
What is the minimum corneal thickness for LASIK?
Average thickness of cornea in Indian is 450 micron to 500 micron& after LASIK there should be around 300 micron thickness of cornea for safety of eye in future.
Does LASIK affect corneal thickness?
Studies have found no increased risk for patients with a corneal thickness of 485 µm who had LASIK or Sub Bowman Keratomilieusis, SBK.
How is Contoura LASIK done?
How long does Contoura LASIK take?
Contoura LASIK can last fifteen to twenty minutes and is generally said to be free of any discomfort. Most patients see a noticeable difference in their visual acuity directly after the procedure and it continues to improve as the eyes heal.
How much does Contoura cost?
How Much Does LASIK Surgery Cost? – Updated 2021
| Type of LASIK | Avg. Cost for 1 Eye | Avg. Cost for 2 Eyes |
|---|---|---|
| Conventional LASIK / Microkeratome | $1,500 | $3,000 |
| Contoura Guided All-laser LASIK | $2,300 | $4,600 |
Which is best LASIK or Contoura?
Following are some of the difference between Contoura vision surgery and LASIK: Better results: The results of Contoura surgery are better as compared to LASIK in terms of visual clarity and correction in refractive error. Some of the patients experience corrections better than 6/6.
Will Contoura increase the cost of LASIK surgery?
Most LASIK surgeons are trying to hold the line on the cost of LASIK surgery, even though their costs are rising, so you should not expect to see much of a price increase for the use of Contoura technology to correct your vision.
What is the best flap thickness for corneal transplant?
For flat corneas, ( K’s <45D ) a 9.5mm ring is recommended to avoid a free cap. With the development of femtosecond lasers, flap creation is more precise, and most surgeons use a flap thickness near 100 microns. With the microkeratome, the most commonly used thickenss is 120 microns.
How is topography-guided LASIK different from traditional LASIK?
Whereas traditional LASIK addresses refractive error by correcting the overall shape of the cornea, topography-guided LASIK also addresses abnormalities affecting the surface texture of the cornea. The advanced, personalized nature of Contoura Vision results in vision that most patients agree is better than anything they’ve…
What are the features of Contoura Vision?
Usually, Contoura Vision technology offers the following features. The technology can treat one number in as low as 1.6 seconds. It offers three kinds of customized treatments. The technology enables the surgeons to save about 40\% of tissue of cornea. It consists the techniques to enhance contrast and improve night vision.
