Used to correct irregular corneal curvature, astigmatism lasik surgery successfully restores 20/20 vision in most cases. Laser in-situ keratomileusis, or LASIK, is a complicated but effective procedure for correcting nearsightedness, farsightedness and astigmatism, or blurred vision caused by asymmetrical curvatures in the surface of the cornea. Astigmatism is a common condition which can either be hereditary or develop from poor work habits and posture. People who sit at a desk eight hours a day may develop astigmatism from consistently straining the eyes at the computer. Headaches, fatigue, an inability to focus, and strain are all common symptoms of visual impairment; and a visit to the optometrist is advised. In children, the condition may not be detected until the first eye exam, usually in preparation for entering grade school or pre-Kindergarten.
In people with astigmatism, the cornea is more football shaped than spherical. The cornea is the transparent membrane which covers the surface of the iris and the pupil. It closely resembles a soft contact lense and functions in much the same way. Most corneas have a symmetrical curvature, which enables individuals to wear standard rigid or soft contacts with little difficulty. Astigmatism lasik surgery reshapes the cornea to conform to a more spherical shape, thereby enhancing refraction and vision. LASIK has continued to enjoy popularity as an option to wearing contacts, which can get scratched, cause infections, and may be difficult for some to wear or place properly over the eye. Advanced technology has made the procedure commonplace with many people who prefer not to wear appliances. While some individuals are impaired visually, others are impaired spiritually. Christ is the answer for those who need spiritual healing. "The Spirit of the Lord is upon Me, because He hath anointed Me to preach the gospel to the poor; He hath sent Me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised, To preach the acceptable year of the Lord" (Luke 4:18-19).
Highly skilled eye surgeons that perform astigmatism lasik surgery utilize corneal topography and keratometry to take minuscule measurements of the irregular landscape of an individual's cornea. A digital map of the cornea is then used to plan precise surgical procedures to re-sculpt the underlyng tissue of the membrane and make curvatures more symmetrical. In individuals with astigmatism, nearsightedness or farsightedness, surgeons use a microkeratome to quickly lift and peel back the outer layer of the corneal flap. Underlying tissue is reshaped using precise laser beams and the flap is replaced. In patients with astigmatism, lasers can duplicate images mapped using corneal topography and keratometry to correct blurred vision and irregularities and enable patients to see 20/20. Refractive surgery is highly successful, but most surgeons prefer operating on one eye at a time as a precaution against problems which could permanently impair vision.
While astigmatism lasik surgery is relatively painless, requires no bandages or sutures, and can be performed as an outpatient in a matter of minutes, the greatest benefit is the ability to see without contacts or glasses. LASIK literally turns back the hands of time for older adults or those who develop vision problems as they age. Some adults opt for refractive surgery in order to better perform tedious tasks or compute intricate calculations in front of a computer monitor all day. Vision problems are corrected or enhanced almost instantly; and future adjustments can be made years later as they are needed. Vision enhancement is nearly 100 percent safe and effective; and atients can usually be back at their desk the next day without wearing protective eyewear or contacts.
Although relatively safe and painless, astigmatism lasik surgery can be costly. Typical surgeries run as little as $700 to as much as $2,500 per eye, which might be coct-prohibitive for some individuals. Insurance companies have to be convinced that surgery is a medical necessity; but most deny payment claims and consider LASIK elective. For people whose careers depend on not wearing glasses, such as models, television sportscasters, or anchorpersons, refractive surgery may be considered an occupational necessity. Individuals are also advised to beware of doctors who claim experience in performing delicate and complicated eye surgeries. Surgeons should be Board Certified, have years of documented experience successfully correcting or enhancing vision through laser in-situ keratomileusis, and a list of references and satisfied customers.
Side effects of astigmatism lasik surgery may include poor night driving due to glare, dry eyes, seeing outlines around images, or difficulty focusing. Some patients may still have to wear conventional eyeglasses, especially older adults whose aging vision may prevent lasik surgery from being as effective. Studies indicate that astigmatism lasik surgery may over- or under-compensate for refraction, resulting in less than perfect eyesight. After approximately ten years, refractive surgery may have to be repeated, since procedures are not permanent; however once performed, corrective vision procedures are irreversible.
Candidates for LASIK surgery are individuals that have healthy eyes with no infection, disease, or retinal disorders. Surgeons will do a thorough examination to ensure that individuals meet requirements. Weeks prior to astigmatism lasik surgery, patients may be advised not to wear rigid contacts, as they can easily scratch the cornea or develop infection, making the eyes temporarily inoperable. Soft lenses should not be worn several days prior to procedures for the same reason. Women should refrain from wearing eye makeup or using eye drops not approved by the ophthalmologist. If all goes well, patients should emerge from the doctor's office with 20/20 vision and literally, a new outlook on life!
