Nature has created the most beautiful world for us to live in and we can see this proof of beauty in every little thing that we come across. The vivid colors are a treat for every eye and help in understanding our world better. However, when this god gifted vision of ours gets blurred due to weak eyesight, our perception of things around us can also change. Although we have spectacles and contact lenses to help us in our handicap, but even these devices is a necessary burden, nevertheless. The glasses are perched on the nose all day long and without them we feel helpless and same are the case with the contact lenses. Inserting an artificial device in your eyes cannot be all that comfortable, even through the new age soft lenses promise comfort and convenience to the user. Hence, considering all these facts, it would be safe to say that nothing can take the place of natural, perfect vision. So then, why not opt for something that can restore your natural vision conveniently? A lasik eye surgery is one such perfect method to achieve this purpose of vision restoration.
A is the procedure of using a laser device to change the shape of the cornea surgically, in order to rectify the vision of the patient. However, the result of the surgery differs from doctor to doctor and patient to patient and hence, one must be very careful about selecting the right eye surgeon to conduct this surgery and also be careful about the tests conducted to check the eligibility of patient to undergo this surgery. A good surgeon for lasik eye surgery can be located with the help of internet or even the yellow pages. A reference of a patient of a particular doctor should also be a good ground for selecting a particular eye surgeon. Once you are comfortable and sure about the choice of surgeon, you can proceed to find out all that you need to know about this surgery.
A basic evaluation of your eye is crucial, before you decide to opt for the lasik eye surgery. In case you are a contact lens user, then you need to stop wearing the lenses and switch to glasses for a particular time period before you undergo the initial check up. It is crucial to stop wearing contact lenses for a significant amount of time as prescribed by the doctor, as the lenses may change the shape of the cornea and cause miscalculations in the required measurements of the natural cornea. Also, your doctor should be fully informed about your eye condition, any medication, which you may be taking and any existing allergies. All this information helps to determine whether you would be a suitable candidate for the surgery or not.
Even once you have been deemed fit to be operated upon for the lasik eye surgery, it is advisable to find out all the facts about the surgery, the procedure, the precautions, after effects and any side effects, if applicable. Once you are sure about these facts, as well as aware about the cost associated with such a surgical procedure, you can go ahead with confidence and hope to see the world with new vision, after the successful completion of the surgery.
Understand Your Options
For the individual looking to reduce their dependency on glasses or contacts, surgical procedures which improve the focusing power of the eye, are a tremendously effective option. The procedure commonly referred to as LASIK is the most technologically advanced way to correct vision, and has helped millions of people worldwide reduce their dependency on glasses and contact lenses.
LASIK surgery uses a cool beam, also known as an excimer, to reshape the surface of the eye, the cornea. By altering the shape of the cornea it is able to change the angle in which light enters the eye. Glasses and contact lenses employ this same theory with an impermanent change. In the past LASIK has had some limitations but now is able to successfully correct nearsightedness, farsightedness, and astigmatism.
LASIK is the most common term used to refer to laser vision correction procedures. All forms of LASIK use an excimer laser to reshape the cornea, but there are variations to the procedure which provide different advantages. A series of vision tests called Advanced Diagnostic Testing allows your doctor to determine which approach is best for you.
LASIK
LASIK (Laser-Assisted in-Situ Keratomileusis) gently reshapes the cornea with the use of an excimer laser. In traditional LASIK, an extraordinarily thin flap is created in the top layer of the cornea and then gently folded back. The underlying layer is then re-shaped with the laser in a matter of seconds, correcting the refractive errors that cause the vision impairment. The flap is then repositioned across the cornea, which naturally adheres and begins to heal within minutes. Of all the laser vision correction procedures, LASIK provides the most comfortable and rapid healing process.
Advanced Surface Ablation
ASA refers to the laser vision correction procedures that treat the surface of the cornea without the creation of a flap. PRK (Photorefractive Keratectomy) and Epi-LASIK are the two most common forms of ASA and refer to the methods of preparing the corneal surface just prior to using the laser. ASA is the safest form of laser vision correction. It allows a wider range of patients to be treated who may not be able to undergo a traditional LASIK procedure due to thin corneas, job restrictions, or other visual issues. ASA is also considered by many to provide the chance for the sharpest and clearest vision, since there are no induced refractive errors associated with a corneal flap. ASA does have a disadvantage because it usually involves a few days of discomfort (treated with Ibuprofen), and a slower visual recovery time, ranging from a few days to a few weeks. Generally, only the most experienced surgeons practice the Advanced Surface Ablation techniques.
Blended Vision
Blended Vision is a LASIK technique you might want to consider if you wear reading glasses or are nearing the age when reading glasses may become necessary. As we get older, we frequently have trouble reading, particularly small or very fine print. This is a natural part of the aging process associated with the lens inside the eye. When this happens, most people need reading glasses. If you use glasses to read prior to LASIK surgery or you remove your glasses to read, you may need to use glasses for reading after LASIK, because LASIK does not treat the lens inside the eye. However, a Blended Vision procedure may provide you with suitable near and distance vision. Blended Vision, also called monovision, is a technique in which one eye (usually the dominant eye) is corrected for clear distance vision, and the other for comfortable near vision. Blended Vision allows a person to see both close and distant objects clearly, though perhaps not quite as crisply as when both eyes are corrected for just one distance or the other. Many people who wear contacts use blended vision today and are very satisfied. Your doctor will demonstrate how this method works prior to your procedure, and thereby help determine if Blended Vision will work well for you.
CustomCornea ®
Wavefront technology is now being incorporated to identify subtle visual distortions, which up to now have been unable to be measured, let alone be treated. Wavefront treatments such as CustomCornea® provide the best opportunity for superior vision compared to that previously available through older, conventional methods of LASIK.
When it comes to LASIK, there are many options to consider. LASIK candidates are all different in their needs and desires for choosing surgery over glasses or contacts. A successful outcome for refractive surgery is dependent upon choosing the best procedure for their needs and a surgeon who specializes in LASIK.
