Laser pointer surgery destroys this fragile pigment on the surface of the iris. Promote the body to remove related tissues naturally. Although the operation itself takes only 20 seconds. But laser pointer takes several weeks for the eyes to turn blue, because the body can only gradually release pigments.
Stromal Medicine Company is determined to develop the safest, most affordable, and most convenient eye discoloration surgery on the market, but it still needs to be licensed by US regulators. The company's medical committee claims that previous studies have shown that the operation is safe, but so far only 37 patients have undergone the operation. Seventeen patients were in Mexico and the remaining 20 were in Costa Rica. The company is currently in the financing stage, while looking for investors. The company hopes to complete clinical trials within a few years. The current cost of brown eyes to blue eyes is $ 5,000.
The medical community, especially the ophthalmology community, is not particularly receptive to this procedure. The basis for their questioning is. The eye is one of the most sensitive organs in the human body. And this green laser pointer operation is irreversible.
"The number one concern with any surgery that releases pigment in the eye is that the pigment may block the microcirculation and cause an increase in intraocular pressure," said Sage Khan, an ophthalmologist at the London Eye Hospital. "If the condition is serious and lasts for a long time, You will develop glaucoma. "
Matrix Medicine claims that the particles released by the surgery are small enough to cause no glaucoma. Although Khan admits that this is reasonable, he and other doctors are reluctant to recommend this Laser Engraver operation. Khan said: "It is theoretically reasonable. But no long-term consequences have been seen. Patients undergoing this operation are not reachable. I would not endorse this operation.
Another factor that determines the visibility of the beam is to adjust the focus of the design features available for certain laser models. For lasers that provide options for expanding or widening the beam, you can identify targets at close or long distances, making them more suitable for long-term aiming. The condensing of light beams will help visibility at close and long distances. So, we return to the question: "How far can I see the laser beam?" As mentioned earlier, there will be many factors to consider, but here is a basic rule. A green laser of 200 mW will be visible above 10 miles, and a blue laser of 1000 mW or more will also be visible on a clear line of 10 miles or more. Factors such as cloud cover, fog, and whether you are at a high altitude should be considered, but based on experience, on 200mW + green and 1000mW laser + blue laser, you can expect a visible distance of more than 10 miles.
