Radial Keratotomy as a Treatment for Near Sightedness

Radial Keratotomy as a Treatment for Near Sightedness. Radial keratotomy (RK) is a refractive surgical procedure used to correct nearsightedness or myopia. Radial Keratotomy was discovered by chance rather than through extensive research. Dr. Svyatoslav Fyodorov discovered the procedure while operating on one of his patients who had been in a bicycle accident. The boy was wearing eyeglasses, which broke on impact and lodged in his eyes. To extract the glass, the doctor had to make several radial incisions in the corneal tissue. When the boy's cornea healed, the doctor discovered that his vision had significantly improved.

Radial keratotomy (RK) involves making a series of micro-fine incisions in the outer portion of the cornea with a high-precision calibrated diamond knife. Because the incisions are superficial and the procedure is relatively painless, the surgeon uses a local anesthetic. Prior to surgery, the corneal thickness of the patient's eye is measured. The diamond-edged cutting instrument is precisely set under the operating microscope before making the incisions. RK can easily correct myopia or nearsightedness by flattening the curvature of the cornea in this manner.

Radial keratotomy was first used in the 1980s in the United States. Initially, it was primarily an experimental procedure, with doctors operating on only one eye at a time and waiting at least three months to observe the results before operating on the other eye. However, as the surgeons gained experience, they were able to operate on both eyes at the same time. Radial keratotomy is now a minor procedure that takes about 15 to 20 minutes per eye.

Radial keratotomy is constantly improving, thanks in large part to rapid technological advances and the fact that a number of such procedures have already been performed successfully. RK, on the other hand, is not as precise as LASIK and PRK. Because RK is less predictable, only a few surgeons now perform it.

Radial Keratotomy (RK) is a surgical procedure that was once commonly used to treat nearsightedness (myopia). During RK, a surgeon made small, radial incisions in the cornea of the eye to reshape it and improve the focus of light on the retina.

RK was popular in the 1980s and 1990s, but has since fallen out of favor for several reasons. First, the introduction of other surgical procedures, such as LASIK, provided patients with safer and more effective options for correcting nearsightedness. Second, advances in contact lenses and eyeglasses have made these methods a more convenient alternative to surgery.

It's important to note that RK can cause some long-term side effects, including corneal instability, decreased visual acuity, and an increased risk of corneal haze and other complications. For these reasons, RK is now rarely performed and is considered an outdated treatment for nearsightedness.

If you are considering a surgical option for correcting nearsightedness, it is best to consult with an eye care professional and discuss the latest, most effective treatments available.

Additionally, it's important to keep in mind that all surgical procedures come with some degree of risk and it is crucial to fully understand the potential benefits and drawbacks before making a decision.

There are newer, advanced surgical procedures available today, such as LASIK, PRK, and SMILE, that have been shown to be effective in correcting nearsightedness with fewer side effects and complications. These procedures use advanced technology to reshape the cornea and improve visual acuity.

It's also important to remember that surgical correction is not the right choice for everyone. In some cases, a combination of eyeglasses, contacts, or other non-surgical treatments may provide the best outcomes.

In conclusion, while RK was once a commonly used treatment for nearsightedness, it is now considered an outdated method and should only be considered as a last resort. Before making a decision about a surgical treatment, it is important to fully understand the potential risks and benefits and consult with a qualified eye care professional.

It's also important to have realistic expectations when considering a surgical procedure for nearsightedness. While the surgery may result in improved vision, it is not a guarantee that vision will be perfect, and you may still need to use glasses or contact lenses for certain activities, such as reading or driving at night.

Furthermore, while RK and other surgical procedures can correct nearsightedness, they do not prevent the progression of other common vision problems, such as presbyopia (the inability to focus on objects up close), or the development of age-related conditions, such as cataracts.

It's essential to take the time to weigh the potential benefits and risks of any surgical procedure and to choose a qualified and experienced surgeon. You should also have a thorough pre-operative evaluation, including a comprehensive eye exam and discussion of your goals and expectations, to ensure that the procedure is the right choice for you.

In conclusion, while RK was once a popular surgical option for correcting nearsightedness, it is now considered an outdated method. If you are considering a surgical treatment, it's important to fully understand the potential benefits and risks, consult with a qualified eye care professional, and have realistic expectations.

A Brief Ovierview Of Lasik Eye Surgery

LASIK, which stands for Laser-assisted In Situ Keratomileusis, is a type of refractive laser eye surgery performed by ophthalmologists to correct vision. The procedure is usually preferred over photorefractive keratectomy, or PRK, because it takes less time to recover and the patient feels less pain overall.

Dr. Jose Barraquer invented the first microkeratome, which was used to cut thin flaps in the cornea and alter its shape in 1960. Dr. Lucio Buratto and Dr. Ioannis Pallikaris invented LASIK surgery in 1990 as a fusion of two previous techniques. Drs.

Stephen Brint and Stephen Slade performed the first LASIK procedure in the US in 1991. Patients who wear soft contact lenses are usually instructed to remove them 7 to 10 days before surgery. The surfaces of the patient's corneas are examined with a computer-controlled scanning device prior to surgery to determine their exact shape. The surgeon uses this information to calculate the amount and location of corneal tissue to be removed during the operation. Lasik surgery is done in two stages: the first is to form a flap of corneal tissue and the second is to remodel the corneal stroma using an excimer laser (193 nm).

When the flap is lifted in the second step, the patient's vision will become blurry and they will only see white light surrounding the laser's orange light. The surgeon repositions the Lasik flap over the treatment area after the laser has reshaped the cornea and natural adhesion holds the flap in place until healing is complete.

Dr. Jose Barraquer (Colombia) invented the first microkeratome, which was used to cut thin flaps in the cornea and alter its shape in a procedure known as keratomileusis around 1960. The world-renowned Barraquer Clinic in Bogota, Colombia, developed and pioneered this procedure.

Dr. Lucio Buratto (Italy) and Dr. Ioannis Pallikaris (Greece) invented LASIK surgery in 1990 as a fusion of two previous techniques, keratomileusis and photorefractive keratectomy. It quickly gained popularity due to its higher precision and lower frequency of complications when compared to the previous two techniques.

Drs. Stephen Brint and Stephen Slade performed the first LASIK procedure in the United States in 1991. The same year, Drs. Thomas and Tobias Neuhann used an automated microkeratome to successfully treat the first German LASIK patients.

Patients who wear soft contact lenses are usually instructed to remove them 7 to 10 days before surgery. According to one industry body, patients who wear hard contact lenses should stop wearing them for at least six weeks, plus another six weeks for every three years.

The surfaces of the patient's corneas are examined with a computer-controlled scanning device prior to surgery to determine their exact shape. It creates a topographic map of the cornea using low-power lasers.

This procedure also detects astigmatism and other irregularities in the cornea's shape. The surgeon uses this information to calculate the amount and location of corneal tissue to be removed during the operation. To reduce the risk of infection after the procedure, the patient is usually prescribed an antibiotic to begin taking before the procedure.

The patient is awake and mobile during the procedure; however, a mild sedative (such as Valium or diazepam) and anesthetic eye drops are usually administered.

Lasik surgery is done in two stages. The first step is to form a flap of corneal tissue. A mechanical microkeratome with a metal blade or a femtosecond laser microkeratome that creates a series of tiny closely arranged bubbles within the cornea are used for this procedure. One end of this flap has a hinge. The flap is retracted, exposing the stroma, or middle section of the cornea. Lifting and folding back the flap can be a painful process.

The corneal stroma is remodelled using an excimer laser (193 nm) in the second step of the procedure. By releasing the molecular bonds that hold cells together, the laser vaporizes tissue in a finely controlled manner without damaging adjacent stroma. To ablate the tissue, no heat or actual cutting is required. The tissue layers removed are tens of micrometers thick.

When the flap is lifted in the second step, the patient's vision will become very blurry. He or she will only see white light surrounding the laser's orange light. This can be perplexing.

Excimer lasers currently on the market employ a computer system that tracks the patient's eye position up to 4,000 times per second, redirecting laser pulses for precise placement. The surgeon repositions the Lasik flap over the treatment area after the laser has reshaped the cornea. Natural adhesion holds the flap in place until healing is complete.

Laser ablation in the deeper corneal stroma usually results in faster visual recovery and less pain.
