Custom Lasik Eye Surgery

The most commonly used refractive surgery procedure is the lasik eye surgery procedure and this is a very popular form of surgery that has the advantage of being less painful and resulting in a 20/20 vision in most cases, usually on the very next day.

The basic lasik eye surgery procedure involves an instrument which is known as a microkeratome which is used in the surgery to create a thin and round flap in the cornea. The surgeon will take the flap and fold it back so that it is not in the way and then takes away some corneal tissue that is underneath with the help of an excimer laser which uses cool ultraviolet light beams to exactly remove very small bits of tissue from the cornea in order to reform it.

Once the cornea is reformed into the correct shape it will work in an improved manner and focuses light into the eye as also onto the retina thereby getting the person to see clearly which will be better than what it was before the lasik eye surgery procedure. Afterwards, the flap is replaced back in place and covers the area where the corneal tissue had been removed.

Corrects Nearsightedness, Farsightedness as well as Astigmatism
Lasik eye surgery procedure is helpful for nearsighted as well as farsighted people. In the case of nearsightedness the aim is to flatten the extra-steep cornea and with farsightedness, a steeper cornea is required. Excimer lasers are also used to rectify astigmatism through smoothening of the irregular cornea and getting it into a more normal shape and the lasik eye surgery procedure will help to achieve this.

There are certain steps to follow before getting your lasik eye surgery procedure performed and these include choosing a good surgeon, finding out whether you are the right person for this type of surgery as well as finding out whether you have any dry eye diseases which need to be treated and cleared prior to the lasik eye surgery procedure.

There are different types of lasik eye surgery procedures such as blade versus bladeless and also custom lasik or wavefront lasik procedures. The wavefront-guided lasik eye surgery procedure makes use of 3-dimensional measurements that figures out how the eye processes images and this is helpful for guiding the laser in reshaping the front portion of the eye that is called the cornea. The wavefront measurement of the lasik eye surgery procedure is extremely useful in extreme and precise individualized vision correction.

Should I Get LASEK or PRK laser eye surgery with astigmatism?

Hello All:

I have been to two board-certified doctors in order to be evaluated for lasik/lasek/prk. My current prescription is:
R SP -4.5 CYL -3.5
L SP -3.0 CYL -3.25

cornea thickness and pupil diameter allow me to be eligible for either prk or lasek.

My questions are:
Can the VISX CustomVue Laser using Custom Wavefront Technology be used to treat my prescription?

What amount of nearsightedness and astigmatism can this laser correct?

Can any other custom wavefront procedures work for me based on my astigmatism? I believe my astigmatism is myopic.

Based on my prescription, what procedure (Lasek or PRK) will likely produce the best result?

If, because of my astigmatism, a custom wavef

If your cornea thickness allows both, then I don't think there is any issue with either. PRK can be used on thinner corneas and if there needs to be a further correction, having PRK makes it more likely to be correctable if you have thinner corneas. But these don't sound like issues to you, since your corneas are fine.

I would suggest PRK. The reasons to do lasik over PRK is that it heals faster, is less painful, and you get instant results. PRK takes a few weeks to get full results (though it will continue to improve for up to a year). And it can be painful for the next couple of days. Also, you will not be able to see well enough to drive or even work for a several days. But, PRK has fewer risks (they can't over cut the flap) and in the long run there are fewer risks since there is no flap to cause problems. (LASIK flaps can come un-seated years afterward if you get hit in the eye, since it never really heals.) Also, PRK tends to improve over the long run, to give you better results. I had PRK and the pain was not significant and I had could take a week off from work. I would say the pain and the time off was totally worth the reduced risk. In my mind, LASIK is for people who are afraid of the pain and want instant results. But PRK is a better procedure with less risk and better results. If it were me, I would go for better results and less risk. And that's what I did. I am happy with my decision.
