Overcoming Visual Impairment With Laser
Impaired vision can affect daily life and reduce a person's quality of life. Several types of visual disturbances, such as myopia, hypermetropia, and astigmatism can be overcome by using glasses or contact lenses. However, sometimes the use of glasses or contact lenses is not effective enough to treat more serious vision problems. One way to treat more serious visual impairment is to use laser technology.
Laser stands for Light Amplification by Stimulated Emission of Radiation. This technology has been used in various fields, including medicine. Laser technology has helped treat many types of health problems, including vision problems. There are several types of laser technology that can be used to treat vision problems.
One of the most common laser technologies used to treat vision problems is laser corneal reshaping technology (LASIK). LASIK is a refractive surgery procedure used to change the shape of the cornea of the eye in order to correct poor vision. The LASIK process involves cutting a thin flap on the surface of the cornea with a microblade or a femtosecond laser. Once the flap is removed, an excimer laser is used to shape the cornea and correct eye refraction. After the procedure is complete, the flap is placed back in place.
Another laser technology that can be used to treat visual impairment is photorefractive keratectomy (PRK). PRK involves using an excimer laser to reshape the cornea, but without creating a flap in the cornea. Instead, the outer layer of the cornea is removed before the laser is used. After the procedure is complete, the outer layer of the cornea will grow back within a few days.
Another laser technology is LASEK (Laser Epithelial Keratomileusis), which is similar to PRK, but creates a flap on the outermost layer of the cornea. In LASEK, the outer layer of the cornea is folded back to reveal the cornea. A laser is then used to shape the cornea and the flap is placed back in place.
There is also another laser technology called Implantable Collamer Lens (ICL) which can be used to treat vision problems. ICL involves placing an implanted lens between the iris and the eye's natural lens to improve vision. These lenses are usually used to correct very poor vision or when LASIK or PRK procedures are not suitable.
Laser procedures to treat visual impairment are quite safe and effective. However, as with any surgical procedure, there are risks and complications associated with laser procedures. Some of the possible risks and complications include infection, eye dryness, blurred vision, light sensitivity, and vision fluctuations. However, these risks and complications are generally rare.
Before undergoing a laser procedure to treat vision problems, you should consult with an eye doctor first. The ophthalmologist will perform a complete eye exam and advise on which type of laser procedure is best for you. In addition, the ophthalmologist will explain the risks and benefits of the laser procedure and provide instructions on preparation and post-procedure care.
After undergoing a laser procedure to treat vision problems, you must follow the post-procedure care guidelines provided by your eye doctor. These guidelines may include using eye drops, avoiding strenuous physical activity, and avoiding direct sun exposure.
In conclusion, laser technology has helped treat many types of serious visual impairment. Laser processes such as LASIK, PRK, LASEK, and ICL can help improve vision and improve your quality of life. However, before undergoing a laser procedure, make sure you consult your ophthalmologist first and strictly follow the post-procedure care guidelines. By following these instructions, you can minimize risks and complications and ensure the success of your laser procedure.
