However, in patients with severe astigmatism or with irregular corneas inducing astigmatism, it is not recommended these patient undergo surgery.

Was radial keratotomy the original lasik procedure?

Was radial keratotomy the original lasik procedure?

No: Radial keratotomy (rk) was a precursor refractive surgery to lasik. In lasik, a circular flap is created and then lifted up to expose the corneal stroma. Then laser is applied and the flap replaced. In rk, radial cuts are made to create relaxing incisions to try and flatten the cornea. Late onset regression and scarring were the side effects. Current technology with lasers is better. ...Read more

Does radial keratotomy vision deteriorate?

Does radial keratotomy vision deteriorate?

Possible yes: Rk is almost never performed now because of the side effects which included regression, scarring, and irregular astigmatism. This was due to the fact that the human hand cannot make 8 or 16 perfectly symmetrical and identical incisions in the eye and that each incision would not heal exactly the same. Many patients with rk now have worse vision and many use contact lenses to treat astigmatism. ...Read more

What is prk vision correction surgery like?

What is prk vision correction surgery like?

Usually good: Prk alters the power of the eye by using the laser to sculpt a new lens into the cornea, the window at the front of the eye. Once healed, the vision is usually excellent and so the vision is as if you never needed glasses because in fact you would not need them. ...Read more

Is lasik eye surgery safe?

Amost always: Nothing is 100% safe. Not even driving a car or crossing a street. Lasik is one of the safest procedures around but it's unrealistic to think in absolute terms of "safe" vs "unsafe". The patient has to be willing to sign the consent form that discloses everything that can go wrong (very rarely) and be comfortable taking a small chance for a big reward. ...Read more

Is polycarbonate eyeglass lens expensive?

Is polycarbonate eyeglass lens expensive?

A little more: Polycarbonate lenses have a higher index of refraction and can be made a little thinner which lightens the eyeglasses and makes them more comfortable. So they charge a little more for them. I consider eyeglass costs way too high for the technology and manufacturing costs, but it is an industry charging what the public will put up with. ...Read more

Tell me the difference between photorefractive keratectomy vs radial keratotomy?

Tell me the difference between photorefractive keratectomy vs radial keratotomy?

Laser vs scalpel: Prk uses a laser to resurface and reshape the front of the eye to improve vision. Rk involves creating multiple radial incisions on the cornea in a symmetrical pattern to flatten the cornea. Prk is much newer and more reliable technology. Rk has many side effects such as regression, irregular astigmatism, and scarring. ...Read more
