What does RK mean in UNCLASSIFIED
Retinal Keratotomy (RK) is a surgical procedure that aims to correct nearsightedness (myopia) by reshaping the cornea, the clear outer layer of the eye. It was a popular refractive surgery technique in the 1980s and early 1990s before being largely replaced by more advanced laser-based procedures like LASIK and PRK.

Shorthand: RK,
Full Form: Retinal Keratotomy

Meaning of RK
RK stands for Retinal Keratotomy. The term "retinal" in this context does not refer to the retina, which is the light-sensitive tissue at the back of the eye. Instead, it refers to the "retina" of the cornea, a layer of collagen fibers that lies just beneath the corneal epithelium. The term "keratotomy" means "incision of the cornea."
Procedure
RK surgery involves making a series of radial incisions (cuts) in the cornea using a diamond knife or a laser. These incisions weaken the cornea, allowing it to flatten out and thus reduce the refractive power of the eye. The number and depth of the incisions are determined based on the patient's individual prescription and corneal thickness.
Advantages
- Less invasive than LASIK: RK is performed on the surface of the cornea, avoiding the creation of a corneal flap as in LASIK.
- Fewer potential complications: RK has a lower risk of complications compared to LASIK, such as flap-related problems or dry eye syndrome.
- Potentially reversible: RK incisions can be closed or revised if necessary, making it a potentially reversible procedure.
Disadvantages
- Less predictable outcomes: RK is less predictable than laser-based procedures, and it can be challenging to achieve the desired level of correction.
- Astigmatism: RK can sometimes induce astigmatism, a condition where the cornea has an irregular curvature.
- Limited range of correction: RK is less effective at correcting higher levels of nearsightedness compared to laser-based procedures.
Essential Questions and Answers on Retinal Keratotomy in "MISCELLANEOUS»UNFILED"
What is Retinal Keratotomy (RK)?
RK is a surgical procedure that involves making radial incisions in the cornea, the clear outer layer of the eye, to correct nearsightedness (myopia).
How does RK work?
The incisions made in the cornea flatten it, which reduces the eye's overall focusing power and improves near vision.
Who is a candidate for RK?
RK is typically recommended for individuals with mild to moderate nearsightedness who are not suitable candidates for other refractive surgeries, such as LASIK or PRK.
What are the risks and complications of RK?
As with any surgery, there are risks and complications associated with RK, including:
- Infection
- Corneal scarring
- Loss of vision
- Double vision
- Astigmatism
Is RK a permanent solution for nearsightedness?
No, RK is not a permanent solution. Over time, the cornea may gradually return to its original shape, reducing the effectiveness of the surgery.
What is the recovery process like after RK?
Recovery from RK typically takes several weeks. During this time, patients may experience blurred vision, light sensitivity, and mild discomfort.
Are there alternatives to RK for correcting nearsightedness?
Yes, there are several alternative refractive surgeries for correcting nearsightedness, including:
- LASIK
- SMILE
- PRK
Final Words: Retinal Keratotomy (RK) is an outdated surgical procedure that was once used to correct nearsightedness. While it offered certain advantages, such as being less invasive and potentially reversible, it has been largely replaced by more advanced and predictable laser-based techniques like LASIK and PRK. Nowadays, RK is rarely performed except in specific cases where other procedures may not be suitable.
