New Laser Eye Surgery
New laser eye surgery is very popular form of vision correction and is a viable option for more and more of the population. Glasses and contact lenses are still commonly used and probably always will be. Advances in surgical procedures and products have taken significant strides the past decade. However, new laser eye surgery procedures are not the cure-all for vision problems. God sends help in so many ways. And the Bible makes reference to the human eye and sight numerous times. Proper vision not only helps people clearly see their physical spiritual world more clearly. God reveals through sight and vision. "It is not expedient for me doubtless to glory. I will come to visions and revelations of the Lord. I knew a man in Christ above fourteen years ago, (whether in the body, I cannot tell; or whether out of the body, I cannot tell: God knoweth;) such an one caught up to the third heaven. And I knew such a man, (whether in the body, or out of the body, I cannot tell: God knoweth;) How that he was caught up into paradise, and heard unspeakable words, which it is not lawful for a man to utter. Of such an one will I glory: yet of myself I will not glory, but in mine infirmities. For though I would desire to glory, I shall not be a fool; for I will say the truth: but now I forbear, lest any man should think of me above that which he seeth me to be, or that he heareth of me. And lest I should be exalted above measure through the abundance of the revelations, there was given to me a thorn in the flesh, the messenger of Satan to buffet me, lest I should be exalted above measure." (2 Corinthians 12: 1-7)
Although new laser eye surgery procedures have grown in popularity since about 1995, there are several risks involved and some people are exclude from using them for a variety of reasons. Today, there are about a dozen possible surgical procedures used to correct vision problems, but two are more commonly used than the others: Photorefractive Keratotomy (RK) and Laser-Assisted in situ Keratomileusis (LASIK). Of the two procedures, LASIK is the more commonly performed procedure. According to online sources, the two new laser eye surgery techniques basically produce the same results. However, because of the differences in how the outcome is produced LASIK has more possible risks of complications. Both of the procedures involve reshaping the surface of eye to produce clearer vision. Back in the 1980s, a technique called Radial Keratotomy was developed and commonly used. Radial Keratotomy involved a surgeon making an incision to flatten the surface of the eye. RK was mainly used to correct nearsightedness. However, the procedure often produced negative side effects such as fluctuating vision, glare, and night vision problems. Now, the procedure is rarely used. That's because new eye surgery techniques have been developed and approved for use.
According to a surgery website, Photorefractive Keratectomy (PRK) was being used in other countries at about the same time RK was being performed in the United States. Photorefractive Keratectomy uses laser light energy to remove tissue directly from the surface of the eye. This procedure alters the curvature of the cornea. In 1995 the Food and Drug Administration approved the use of PRK in the United States. PRK has been upstaged by LASIK for several reasons. But PRK has some advantages over the new laser eye surgery. Since nerves appear to regenerate faster with PRK, there is less risk of some complications developing. The main differences between the two procedures are that Keratectomy is a surface procedure and LASIK involves creating a small thin surgical flap. During the LASIK procedure, the surgeon lifts the surface flap and then uses a laser to reshape the eye. Once this is done, the flap is replaced. Unfortunately, there are two possible risks with creating a flap. First, the flap could be damaged or detach completely. Second, improper healing of the flap could distort the cornea. However, there are other complications that could arise during and after eye surgery.
Research all the new laser eye surgery procedures and consult a surgeon for more specific details. Apparently, LASIK's main advantage is that there is little discomfort following the procedure. Also, unlike PRK, the patient's vision clears within hours instead of days. During the past decade, several forms of LASIK have been developed: LASEK, EPI-LASIK, Blade-free LASIK and Wavefront LASIK. Generally, the main difference is how the flap is created. And there are several other types of corrective procedures being used. For example, Conductive Keratoplasty uses a probe and heat radio waves to steepen the cornea. This procedure is useful for people who are farsighted. Implantable Lenses are similar to contact lenses but are surgically implanted to correct nearsightedness. Refractive Lens Exchange is similar to cataract surgery and helps eliminate farsightedness. Cataract surgery is useful for correcting both nearsightedness and farsightedness. All the procedures have a common goal: allow people to see better and live more productive lives.
Although new laser eye surgery procedures have grown in popularity, they are not right for everybody. Consult with a surgeon to find out which procedure, if any, is the best one. In most circumstances, people under the age of 18 are rarely considered for laser vision surgery procedures because their eyes are still changing. Certain health conditions and diseases could preclude a person from some types of vision correction procedures, too. Most laser procedures are performed quickly and without pain. During the laser vision procedure, the eye is anesthetized using drops and there is often no discomfort during the surgery, which normally takes 15 to 45 seconds to perform. Apparently, few side effects are experienced following laser surgery. Sources indicate that the most common are a halo effect and glare around lights. However, most people usually return to normal activities within a few days of undergoing a new laser eye surgery procedure.
Lasik Laser Eye SurgeryThe demand for lasik laser eye surgery has increased in recent years, perhaps due in part to the fact that this procedure is seen as a relatively simple way to regain accurate vision. Typical problems that impact the quality of vision may include myopia, astigmatism, and hyperopia. Glasses or contact lenses are the most common methods of correcting vision problems. But for some patients, laser surgery is seen as a way to regain correct vision and eliminate the need for glasses or contact lenses. Myopia, also known as nearsightedness, exists when a patient has a hard time seeing objects that are at a distance. Hyperopia, also known as farsightedness describes the condition of having accurate vision at a distance, but experiencing difficulty seeing objects at close range. An astigmatism involves retina distortion and corneal irregularities. Correcting these problems through lasik laser eye surgery involves the removal of corneal material through the use of lasers. A surgeon who is skilled in this area of medicine will be needed to handle such a delicate procedure. Just the right amount of corneal tissue is removed so that the eye is once again able to focus correctly at all distances. This surgical reshaping of the cornea has corrected the vision of multiple thousands of patients, but only a qualified doctor can advise an individual on whether or not they are good candidates for the procedure.
Anyone who is considering lasik laser eye surgery should take the time to talk to their doctor beforehand and decide whether or not this option is a good choice. If a potential patient suffers from additional eye diseases, such conditions should be taken care of before surgery is scheduled. To determine what needs to be accomplished during surgery, a photographic device called a corneal topographer will be used. Information that is obtained by this device will tell the doctor how to proceed during the procedure. Additionally, there are certain medical conditions unrelated to the eye that can make impact the suitability of laser surgery. For this reason, it is very important that a patient fills the doctor in on all health concerns.
Amazingly enough, lasik laser eye surgery will usually only take about five minutes in total. These surgeries are usually out patient procedures and the patient will generally be conscious for the entire time. A sedative will usually be administered beforehand, albeit a mild one. While the patient will be able to walk in before the procedure and walk out afterward, they will need someone to drive them home since vision will be temporarily impaired. The patient can also opt to have both eyes operated on the same day or may choose to have one eye done at one time and the other one operated on the following week. As with all surgical procedures adequate rest and recuperation are called for.
After lasik laser eye surgery, patients can expect a number of common symptoms. For some patients, a itchy, burning sensation may be present as well as a false sense of having a foreign object in the eyes. A pain reliever may be recommended by the physician to provide relief. The eyes may water and tear up, but such reactions are perfectly normal. Vision will temporarily be somewhat blurry. Perhaps one of the hardest aspects of recovery after lasik laser eye surgery is a desperate need to rub the eyes. Patients should do whatever they can to resist this temptation. Damage to the eyes could be caused by this rubbing. It will take the eyes a few days to recover from this procedure. Patients should expect a certain amount of sensitivity to light and the whites of the eyes will likely appear to be red or bloodshot. When opting to undergo lasik surgery, the patient should make sure to schedule a few days off of work. In most cases, the surgeon will wish to see the patient within twenty four to forty eight hours after the procedure. The Bible describes the believer's dependence upon God and the hope that is available in Him. "My soul fainteth for thy salvation: but I hope in thy word." (Psalm 119:81)
Follow up care for lasik laser eye surgery may include the use of prescribed eye drops that will work to ward off the possibility of inflammation and infection. Because vision will be blurred at first, many patients are tempted to put in their contact lenses. But these lenses should not be worn on eyes that are recovering from this procedure. Sports and other activities should not be resumed until the doctor advises that this is all right. Since the eyes are susceptible to infection following lasik laser eye surgery, make up and lotion that is applied near the eyes should not be used for at least two weeks. Hot tubs, whirlpools, and swimming should be avoided for a month or two, depending on the surgeon's recommendations. Certain visual issues may also be present for up to six months post surgery. This is due to the fact that the patient's vision will need time to stabilize and is not generally a cause for concern. Such visual disturbances might include halos, glare and impaired night vision. Unusual symptoms or a worsening of symptoms that are already present will require immediate medical care. Left untreated, a patient could experience extreme impairment or even total loss of vision. But with adequate care and attention, patients are able to enjoy corrected vision for years to come.
