Treatment covers Common Vision problems like:
Lasik is a widely performed laser eye surgery, in which, a thin flap in the cornea is created using either a microkeratome blade or a femtosecond laser. The surgeon folds back the flap, and then remove some corneal tissue underneath using an excimer laser For most people. Laser eye surgery requires only topical anesthetic drops, and no bandages or stitches are required. LASIK provides a long-lasting alternative to eyeglasses or contact lenses. Success rate of LASIK procedures range between 92 and 98 percent.
Farsightedness (Hyperopia): A commonly prevalent vision abnormality, hyperopia refers to the difficulty in focusing on objects that are close. This condition is triggered by an abnormally flat cornea that does not allow light to sharply focus on the retina. Glasses, contact lenses, or surgery are used to treat hyperopia.
Nearsightedness (Myopia): An eye sight abnormality where a patient Is unable to see distant objects clearly, though they can see nearby objects clearly. The principal cause is that of the cornea having too much curvature, resulting in problems with focusing on the retina. Myopia is extremely common and readily corrected with eyeglasses, contact lenses, or surgery.
Astigmatism : A common cause of faulty vision or impaired eye sight condition is astigmatism. Here images are blurred due to an irregularly-shaped cornea. Prevalence of Astigmatism is also proportionate to age and also common in nearsighted people.. It is generally treated with glasses, contact lenses, or refractive laser eye surgery.
Generally, laser eye surgery is pain less and should not take more than 15 minutes for both eyes. A patient gains improved vision without the aid of any eyeglasses or contact lenses . Within 24 hours a patient can begin seeing post the surgery.
If you're not a good LASIK candidate, a number of other vision correction surgeries are available, such as PRK and LASEK laser eye surgery and phakic IOL surgery. It is only your ophthalmologist, who will decide on one of these procedures suitable for your condition; besides which particular technique is best specific to your case.
Laser eye surgery offers numerous benefits and can dramatically improve your quality of life. Most people achieve 20/20 vision or better after the surgery although the results vary depending on individual cases & the expertise of the surgeon. You may still need to wear glasses or contact lenses following laser vision correction, though your prescription level typically will be much lower than before.
Largely the LASIK procedure has an excellent safety profile,. However complications can occur and may include infection or night glare. A few patients may well l need a LASIK enhancement, or "touch up" procedure, a few months after the primary LASIK surgery to achieve acceptable visual acuity.
Before considering LASIK Eye Surgery, you should review the variety of different non-surgical ways refractive disorders can be corrected. All have benefits and drawbacks.
Glasses : Glasses are time proven and have been in existence for a thousand years. They are affordable (unless you buy multiple pairs of designer frames), easy to maintain, and versatile. They may, however, restrict peripheral vision, be difficult to wear in certain weather conditions, cause magnification of images, cause a number of visual aberrations (including halos around lights), and have a limited usage life. They may interfere with certain occupations and recreational activities, and some people don't like the impact glasses have on their appearance.
Contact Lenses : Contact lenses are another common solution for the correction of refractive visual problems. Advantages include more natural vision, no change in cosmetic appearance, improved visibility, more freedom in recreational activities, and better peripheral vision. On the other hand, contacts are high maintenance, may get lost, are less comfortable for patients with dry eyes, may cause visual aberrations (including halos and fluctuating vision), and always carry an increased risk of infection and possible corneal scarring. In higher altitudes many adults become intolerant of contact lenses over time because of dry climate and decreased oxygen in the air.
There are so many types of contact lenses available today - soft, rigid, gas permeable, toric for astigmatism, etc. – to suit people with nearsightedness, farsightedness, or astigmatism, For people who are presbyopic and over thirty-five, contact lenses can be fit asymmetrically to obtain monovison for reading. Ophthalmologist and optometrists recommend not sleeping with any contact lens in because this increases the chance of corneal infection.
Refractive surgical procedure intended to reduce a person's dependency on glasses or contact lenses. The most common refractive surgical procedures performed today are:
LASIK (Laser In-Situ Keratomileusis) : It is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses. In this procedure a thin hinged flap of cornea (the cornea is the transparent, dome-shaped window covering the front of the eye) is created and lifted to one side in order to allow laser treatment to the deeper part of the cornea. The flap is then repositioned in its original position.
EpiLASIK (Epithelial Laser-Assisted In-Situ Keratomileusis: EPI LASIK) – it is a procedure, which combines the advantages of PRK and LASIK, Epi lasik involves the use of a microkeratome, similar to LASIK, however only the superficial epithelial layer of cornea is separated as in PRK and this flap is replaced following the reshaping of the cornea using the Excimer Laser.
PRK ( Photorefractive Keratectomy ), which was the original kind and is still sometimes used. It involves gently scraping some surface cells off the cornea and then using a laser beam to re-shape it.
Your treatment will begin with a basic Lasik consultation followed by a 'Corneal Topography' test, a pre-Lasik safety test which would help your Lasik Consultant determine the most suitable 'Lasik Process' for you. If any further tests are found to be needed besides Corneal Topography to ascertain the same. The findings of these tests are relevant and valid for a period of 3 months, if however you wish to have the process performed after the specified period you may have to repeat all the tests to ascertain the current status of your eyes.
