Eye Laser Refraction center offers refractive laser surgery
Eye Laser Operation in Bangkok Thailand in one of the leading private eye clinic in Bangkok. The newest technology from Zeiss Germany. Nearsightedness or myopia Nearsighted people can see things that are close, but they cannot see clearly in the distance. Nearsightedness usually results from an eye that is too long in relation to its focusing parts. Because of this extra length, the lenses cannot focus the light rays from distant objects on the retina. Instead, the images focus in the center cavity of the eye and then diverge into a blur by the time they reach the retina.

Farsightedness or hyperopia
Farsighted people may see things in the distance, with extra focusing effort, but they cannot see clearly up close, unless they are young and use additional effort. Farsightedness is a focusing problem usually resulting from an eye that is too short. Because of the reduced length, the muscles adjusting the lens may fatigue, or the lens may not be able to respond enough to focus the light rays. The retina thus receives a blurred image of light. The noticeable effects of farsightedness increase with age as the inner lens loses its ability to vary its focus to compensate for the problem.
Astigmatism is a general inability of the eye to clearly focus images from any distance because of unequal curvatures of the cornea. Instead of being spherical, an astigmatic cornea has more curvature in one direction than another. It has two curvatures, similar to a football rather than a well-rounded basketball. Nobody has a perfectly shaped cornea, but the distortion of most eyes is so slight that it does not significantly affect vision. However, more than a small degree of astigmatism can noticeably blur vision. Astigmatism can occur alone of along with nearsightedness or farsightedness.
Presbyopia is a universal focusing problem developing in most people around 45 years of age. When eyes are young, the gel inside the internal natural lens is soft so it can change shape to allow people to focus on things at various distances. But as the eye ages, the gel hardens and the lens enlarges and loses its ability to change shape to focus on near objects. People with natural 20/20 distance vision will likely need reading glasses when presbyopia develops.
A procedure called LASIK may be the way to achieve clear, natural vision. This procedure had its origins back in the 1960’s and has evolved over the years into a safe and effective operation. The current technique involves both the use of conventional and laser surgery to correct nearsightedness, farsightedness and astigmatism.
In performing LASIK, the surgeon first uses a special oscillation blade to make a partial cut through about the 1/3 of the front surface of the cornea, creating a flap of clear tissue on the central part of the eye. The Patient is then positioned under the excimer laser which has been programmed to vaporize away some of the internal corneal tissue under the flap. Central tissue is removed to reduce curvature and correct nearsightedness. Peripheral tissue is removed to increase curvature and correct farsightedness. Astigmatism can be corrected by removing selected tissue to even out the curvature of the cornea.
After the laser has removed the selected tissue, the flap is closed over the eye. The corneal tissue has extraordinary natural bonding qualities that allow effective healing without the use of stitches.
Qualifying for refractive surgery
- Be at least 18 years of age (21 for some procedures)
- Have stable vision for one year-minor fluctuations may not disqualify you.
- Have a correctable vision problem
- Have eyes free of complication in juries and diseases (assessed individually)
- Must not be pregnant or nursing
Note: Since the contact lens distorts the cornea, please remove soft lenses 3 days (7 days for hard or gas permeable lenses) before the assessment and the operation.
Will the LASIK procedure be painful?
You should not feel any sharp pain. Only the slight pressure from the surgeon’s hands and instruments.
When can I go back to work?
This will vary depending on the type of work performed, and how fast you heal. Some patients return to work the next day, while for others it may be several days before they are ready.
Is there pain after LASIK surgery?
Once the numbing medication wears off (approx. 1 hour after surgery), you may notice tearing, irritation, and sensitivity to light. Make sure you take the pain medication provided and try to take a nap. After a few hours most patients are noticeably more comfortable.
