When patients receive corrective laser eye surgery, their vision can be greatly improved, enhancing the quality of life. In some cases, patients that receive LASIK procedures have regained a near perfect twenty-twenty vision, allowing them to see the world without the aid of glasses or contact lenses and allowing a freedom from these encumbering tools. Evolving and improving as they become more and more popular, these in office surgical procedures are drastically changing the way many people see. Those who want to consider corrective eye surgery should first, however, obtain in-depth information about the process, learning what to expect before and during the procedure. Also, not every person is a good candidate for LASIK, so individual evaluations will be necessary. There are risks involved with this high tech process so patients should be well advised before undergoing this very popular, yet major surgery.
Laser Assisted Situ Keratomileusis, or LASIK, is a surgical process that uses an intense laser beam as a means for cutting areas in the eye to permanently alter the shape of the cornea. Doctors utilize laser beams in corrective laser eye surgery to open two different flaps over the cornea, gaining access to the small area that reflects light. When the flaps are opened, the middle section of the cornea, or the Stoma, is accessible, and a monochromatic beam is used to evaporate a portion of it, altering its shape. When the cornea has been reshaped, refraction is perfected and near sighted and far sighted vision problems are greatly improved.
The shape of the cornea determines how well a person can see, in the context of astigmatism problems. Eye diseases are another matter entirely. The cornea is the part of the eye that focuses light and helps create an image on the retina. When the cornea is slightly misshapen, light patterns cause distortions on the image being sent to the retina. Often, corneas that do not reflect light properly are inherited. Those who have parents that wear glasses are likely to have the same sight problems. But, once the stoma is reshaped to near perfection with corrective eye surgery, light refraction greatly improves, giving the patient better site. There are different lasers and techniques used in surgeries to alter the cornea.
Usually performed in a doctors office, corrective laser eye surgery generally takes less than thirty minutes. The entire process begins when numbing medications are placed in the eye and surrounding areas. This area is then thoroughly cleaned to protect against infection. A device is placed over the eye to keep the eyelid open and from blinking. Then, another devise is used to apply pressure pulling the cornea forward. Laser beams are then used to open the flaps and reshape the cornea. After corrective eye surgery, there will be a protective covering placed over the area and this covering is worn to protect the eye during the healing process.
Patients should know what to expect during the post-op period. Some have experienced diverse side effects immediately following corrective laser eye surgery. Dry eyes or excessive watering may result. Patients may also experience short-term problems with night glare and blurred vision. These post-operative conditions are considered to be normal, but should always be reported to the attending physician. There are also cases where patients have experienced long-term side effects that led to another corrective laser eye surgery procedure. It is vital that patients understand the risks involved with the surgery and the potential for less than perfect results. This operation has become so popular, so wide spread, and so competitive, some are rushing to have LASIK procedures without the information needed to make wise choices.
Seeking counsel before determining if this procedure is right for any individual will be vital. As mentioned earlier, not every sight problem can be corrected with LASIK, and it is important to discover who is a candidate and who is not. Those hoping to have vision corrected with this procedure should seek out medical doctors that will carefully explain the procedure and all risks to patients. Then, prayer should be initiated, seeking the counsel of God, who knows and sees all. "Ask and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: for every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened." (Matthew 7:7-8)
Anyone suffering from the most common optical conditions, hyperopia, myopia, astigmatism, or a combination of, are the most likely candidates for this surgery. Refractive instability is a condition that causes the eye's ability to focus light to change often, making this diagnosis impractical for corrective eye surgery. Also, patients who are pregnant, who have fluctuating hormones, diabetes, or other diseases that prevent proper healing should not consider this process. Cataracts are addressed by slightly different procedures and should also be thoroughly investigated when considering this surgical procedure.
