What is the minimum power for Lasik surgery?
A normal Indian cornea has a central thickness of 530 microns or 0.53 mm. In this thickness, one can safely correct power of -8.0 by SBK (thin flap LASIK) or the Bladeless Femto LASIK. A cornea which is less than 495 microns is considered thin, while a thickness of fewer than 450 microns is a ‘no go’.
Can I do LASIK if my power is?
Unstable glass power: LASIK is best done when eye power has been stable for atleast one year. What one needs to understand is that LASIK removes the eye power as per the current eye power. If eye power is not stable and is bound to increase in future, then even after a previous Lasik, eye power will increase.
Can you get LASIK If you have a high prescription?
Options for People with High Prescriptions Thanks to modern technology, it’s possible to use LASIK to correct virtually any prescription, even those that are extremely high.
How do I know if LASIK will work for me?
The best way to determine if you are a candidate for LASIK is to work with a highly qualified surgeon and have a complete evaluation of your eyes and vision. Then both you and your surgeon will have the information needed to make the best recommendation for you.
What prescription is too bad for LASIK?
To qualify for the newest LASIK technology (topography-guided LASIK), your refractive prescription should fall within the following: Up to -8.0 diopters of nearsightedness, or. Up to -3.0 diopters of astigmatism, or.
Can I get LASIK if I have really bad vision?
Yes, it can. However, you must also meet other requirements outside of prescription limits in order to be a good candidate for LASIK. These include: Having corneal tissue that’s thick enough — approximately 420 microns — for LASIK.
Is there a limit to the power range of LASIK?
There is a limit to the power range for Lasik but it varies from patient to patient and their corneal thickness.
What are the requirements for LASIK surgery?
Having corneal tissue that’s thick enough — approximately 420 microns — for LASIK. Most healthy eyes have corneas that around 550 microns thick. Your eye health, in general, must be in good standing
What is the average corneal thickness for LASIK?
The major aspect of Lasik is the corneal thickness and the average corneal thickness found in the human eye is 520mm- 540mm. The value of spec power which can be corrected depends on Corneal thickness. Your cornea needs Yes, Lasik has a certain correction range for specs power.
What are my LASIK options if I have bad eyesight?
There may be other options available if you are outside the recommended limits for LASIK correction. Common refractive errors like myopia, hyperopia, and astigmatism are measured in diopters (D). A prescription of 0.0 D, also called “plano” would be very good vision; the further from 0, the stronger the error in your vision.
