Myopia is a big threat to young adults. Some are congenital, and some are acquired after birth. Nowadays, many treatments are put to use to correct their eyesight, such as eyeglasses, contact lenses and laser eye surgery. A plenty of young adults aged 20 to 25 prefer laser eye surgery to other prescriptions. Now that the cost of glasses or contacts is as much as a surgical procedure, the advantage of laser eye surgery is very obvious. The expense is not very much and it can solve the eye problem only by one surgery. Therefore a greater number of young adults choose to laser eye surgery to enhance their eyesight.
But does everyone can be treated by this method? The answer is absolutely no. Ophthalmologist suggest that young adults wait for at least two years after their eyesight is steady, as nearsightedness changes a lot in youth and can be steady at around 30.
After all, criterion above is not very clear and sometimes can be subjective. Whether to operate or not is still determined by the pre-op examinations. Only those who pass the exam have a good prognosis on operation.
If nearsightedness reduces the quality of one’s life, people with age-related eye problems suffer more. More than 200, 00 people in U.K. are blind due to old age. So ophthalmologists rack their brains to develop a technique to cure this disease. A professor at King’s College named John Marshall is doing a research about how to delay age-related macular degeneration (AMD), and acquires primary effect.
Now here I will introduce the principle briefly. Behind the retina, there’s a thin membrane in which stays a lot of waste. John Marshall stimulates enzymes to clear the waste away so that the function of eye can get its breath again. The result of trial in clinical is delightful. But it’s not enough, and more efforts must be made to improve the technique. Marshall has a dream that the treatment will be put to use in clinics in the next two to five years.

Laser eye surgery is one of the most valuable medical developments of our lifetime. It has given ophthalmologists a tool to improve sight and in most cases eliminate the need for glasses for good.
Since the new technique was perfected in the late 1980s it has transformed thousands of lives and continues to grow in popularity. This highly specialised procedure allows surgeons to reshape the eye’s cornea correcting the faults that cause blurring of vision. The treatment can be used to correct both Myopia (nearsightedness) and Hyperopia (farsightedness) so the days when thick glasses or contact lenses were the only option to see clearly are gone.
The idea of laser eye surgery has been around since the 1950s and was the result of several different doctors who all played a part in the advance of the procedure. The technique was initially the innovation of Jose Barraquer, a Spanish ophthalmologist who first came up with the idea of cutting into the eye’s cornea to alter its shape.
Twenty years on, the radial keratotomy procedure was developed by the Russian doctor, Svyatoslav Fyodorov, who stumbled upon the important finding when he was treating a boy who had fallen and cut his eye on his glasses. Fyodorov discovered that by shaving off the front layer of the eye the young boy had recovered with better sight than before.
The development of the Excimer laser by a group of scientists from the University of California turned the eye surgery dream into a reality and, because of the inventiveness and dedication of these doctors, the first pioneering surgery was performed in 1989 in Greece. Since then the operation has become a common procedure performed around the globe.
Further developments to the procedure have resulted in two main types of laser eye surgery. Photorefractive Keratectomy, commonly known as PRK, a procedure carried out on the surface of the eye, and LASIK surgery, which differs because of the incision made to the surface of the eye and the laser treatment that is applied to the corneal tissue beneath.
Because of the delicate nature of an eye the operation needs to be performed with great care and, although the technology sounds complicated, in the hands of a qualified practitioner it is a relatively straightforward one. In general, the operation takes around 30 minutes although the actual laser treatment can take as little as a minute.
The technology and development of laser eye surgery has resulted in a simple painless procedure with a very quick recovery time. Today the surgery boasts a 95% success rate with most patients enjoying full 20/20 vision which is a testament to the brilliance of the doctors who invented the ground breaking operation.

Many of my friends have had Lasik. Why do you sometimes recommend “Lasik without a flap”?
According to a top qualified Los Angeles eye surgeon, there are certain people for whom “Lasik without a flap” is the preferred technique. In the following situations, “Lasik without a flap” is the safer choice: moderate to extreme dry eyes, very thin corneas, thin corneas combined with large corrections, irregular topography (curvature test) that may indicate an inherent weakness in the cornea, or hobbies or professions (such as boxing) where there is a very high likelihood of being hit in the eye. Safety needs to be our most important consideration, and for these certain people, “Lasik without a flap” is safest.
What Are The Disadvantages Of “Los Angeles Lasik Without A Flap”?
There are two disadvantages. The main disadvantage is that “Lasik without a flap” takes longer to heal. The vision is often around 20/40 to 20/50 during the first week. 20/40 vision is required to legally drive a car. You will certainly have adequate “walking around” vision to perform most daily tasks, but it is certainly possible that you will not see well enough to legally drive or see clearly enough to work at a computer or read extensively during the first week. Although most people choose to have both eyes treated on the same day, some people choose to have “Lasik without a flap” one eye at a time, and then they can work during the first week while the eye is healing. With Lasik, most people return to work the very next day. The second disadvantage is on and off discomfort during the first week, which is very well controlled with “comfort” drops as well as anti-inflammatory pills.
Do you perform other forms of laser vision correction in addition to
“Lasik without a flap”?
Among the many services provided by your experience Lasik doctor Los Angeles patients have all the variations of laser vision correction, including Lasik, IntraLasik (Lasik with a laser flap), and “Lasik without a flap” available as possible laser eye correction options.
I want the Custom Wavefront treatment. Can I have that with “Lasik without a flap”?
Yes, we can perform the Custom Wavefront treatment with Lasik, IntraLasik, and “Lasik without a flap”.
How is “Lasik without a flap” performed?
As explained by a top Lasik surgeon Los Angeles without a flap uses the exact same laser as Lasik or IntraLasik. However, instead of creating a flap (which is the thickness of a human hair) and then performing the treatment on the part of the eye under the flap, the treatment is performed near the surface of the eye. This is why this technique is often referred to as Advanced Surface Treatment. The thin layer of material covering the surface, which is very soft, is wiped away, and the laser treatment is then applied to the firmer material underneath.
Which gives better results: Lasik, IntraLasik, or “Lasik without a flap”?
In our hands, the final vision is the same with each of these variations. Lasik provides the most rapid return to excellent vision, followed by IntraLasik, and then “Lasik without a flap”. We want to make the recovery as easy and quick for you as possible, but our main concern is which technique will be the safest technique for your particular situation.
What care is required after “Lasik without a flap”?
A special contact lens, which we put in and later take out, is worn for 5-7 days. You will need to take antibiotic and anti-inflammatory drops, and we will give you anti-inflammatory pills.
Is “Lasik without a flap” very common?
About 10% of the laser treatments in the United States are “Lasik without a flap”. It has been performed since 1995, and very significant improvements have taken place over the years. Advanced Surface Treatment is becoming more popular each year, as doctors understand that for certain groups of people it is the safest choice.
