Can radial keratotomy vision deteriorate throughout life?

Maybe. One of the long term problems with rk surgery is the lack of long term stability in some patients. Sometimes, their prescription keeps changing over time, usually making them become more far-sighted. There are some therapies available that may help. Consult a corneal specialist.

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.

40 years old guy, one of my eye is as doctors say lazy eye, radial keratotomy done 15 years back, the vision of this eye is 8.5 cyl. Suggest treatmnt?

Second opinion. A lazy eye is one which while apparently normal, does not see well usually from childhood issues. If not the case, then there is some other problem. Radial k. Have a high rate of regression which might be part of the cause. I suggest you make an appointment with a corneal surgeon to have this evaluated and get a second opinion there.

Can I perform my own radial keratotomy?

Yikes. You could numb your eye with medication so you could do this painlessly. But you have no ability to control the cutting instrument on yourself. The likelihood is that you would slice open your eye and need emergency surgery. Do not do this at home. Anyway, lasik has totally replaced radial keratotomy as a more predictable and safer therapy.

How long does the radial keratotomy take?

Quick. The actual surgery is very fast, often taking less than 5 minutes. However the measurements of the cornea to accurately perform radial keratotomy (rk) should take some time, up to 20-30 minutes to check corneal shape and thickness at various points on the eye surface. Rk has fallen out of favor and has been replaced in most cases with prk using the laser, or lasik.

Is radial keratotomy a very common procedure?

Not any more. Rk or radial keratotomy was once very popular as a refractive surgery about 25-30 years ago, but there have been safety concerns due to the very deep incisions needed in the cornea. Laser procedures such as lasik, lasek and prk or photorefractive keratectomy have mainly replaced rk.
No. Rk was performed before laser refractive surgery was available. Although it was effective in a lot of people, the results were quite variable and over time many patients noted major changes in their prescriptions. Laser procedures are far more accurate, and treat the upper 10% of the cornea, rather than the nearly full thickness of it.

Is there any pain involved in a radial keratotomy?

Mild discomfort. Radial keratotomy is an older form of vision correction surgery that is rarely performed today. It involves making tiny incisions into the cornea in order to change its shape. While the procedure itself is painless, it is not uncommon for people to feel a "scratchy" sensation for a day or so after the procedure. Artificial tears can decrease the discomfort. Speak to a doctor about lasik/prk.

Can overcorrection by radial keratotomy be treated?

Yes. The common way is to use glasses or contact lenses. Laser vision correction can also work. See your ophthalmologist to discuss the various options with you.

Did anything bad happen to the people who got radial keratotomy over the years, since it was long ago?

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.

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.
No. No. Although rk preceded lasik is was a surgery performed by a blade and not by a laser. It was not as precise and long term stability of prescription was poor.
