If you're fed up with wearing contacts or glasses, you may be considering Lasik eye surgery – a process to correct vision problems. Prior to signing up for that surgery, obtain a clear picture of the items you can expect.

Understanding Your vision


-->

To see clearly, the cornea and also the lens must bend or refract light rays so that they focus on the retina – a layer of light-sensing cells that line the rear of the eye. The retina converts the sunshine rays into impulses which are sent to the mind, where they're recognized as images. When the light rays don't concentrate on the retina, the image the thing is is blurry. This is known as a refractive error. Glasses, contacts and refractive surgery attempt to reduce these errors by looking into making light rays concentrate on the retina.

Refractive errors come from an imperfectly shaped eyeball, cornea or lens, and therefore are of three basic types:

  • myopia – nearsightedness – only nearby objects are evident.
  • hyperopia – farsightedness – only objects a long way away are clear.
  • astigmatism – images are blurred, whether or not they are near or a long way away.

There's also presbyopia – “aging eye,” a disorder that usually occurs between ages 40 and 50, which can be corrected with bifocals or reading glasses.

Are you currently a Good Candidate for Lasik?

Lasik isn't for everyone.

  • You ought to be at least 18 years of age (21 for many lasers), because the vision of individuals younger than 18 is still changing.
  • You shouldn't be pregnant or nursing; these conditions might alter the measured refraction from the eye.
  • You shouldn't be taking certain prescription medications, such as Accutane or oral prednisone.
  • Your vision must be healthy as well as your prescription stable. If you're myopic, you need to postpone Lasik until your refraction has stabilized, because myopia will continue to increase in some patients until their mid- to late 20s.
  • You ought to be in good overall health. Lasik might not be recommended for patients with diabetes, rheumatoid arthritis symptoms, lupus, glaucoma, herpes infections from the eye, cataracts, keracotonus (a problem of the cornea), and retinal disease. Discuss your current health status together with your surgeon.
  • For those who have had issues with “dry eye,” either from wearing contacts or another reason, engage with your eye doctor about how exactly this could impact Lasik.
  • Weigh the potential risks and rewards. If you're happy wearing contacts or glasses, you might want to forego the surgery.
  • Understand your expectations in the surgery. Could they be realistic? Generally, having inadequate eyesight cuts down on the chance of Lasik eye surgery success and boosts the chance of retreatment.
  • Ask your physician if you're a candidate for monovision – correcting one eye for distance vision and also the other eye for near vision. Lasik cannot correct presbyopia to ensure that one eye can easily see both near and. However, you can use it to correct one eye for distance and also the other for near. If you're able to adjust to this correction, it might eliminate or lower your need for reading glasses. Sometimes, surgery on just one eye is needed.
  • Discuss workplace requirements and lifestyle activities, like sports and recreation, together with your doctor to ensure Lasik is suitable for you.

Risks and Possible Complications

Prior to the surgery, your surgeon should show you the risks and possible complications, and potential negative effects, including the benefits and drawbacks of having either eyes done on the day that. This is the “informed consent” process.

Complications may include:

  • over- or under-correction. These complaints often could be improved with glasses, contacts and retreatments.
  • corneal infection.
  • home loan business contrast sensitivity, “crispness,” or sharpness. This means that even though you might have 20/20 vision, objects can happen fuzzy or grayish. This really is referred to as “Lasik 20/20 or 20/40.”
  • flap problems, including: irregular or incomplete flaps, ingrowth of cells underneath the flap that may have to be surgically removed, and irregular healing that produces a distorted cornea, which could only be corrected having a corneal transplant.
  • “loss of best corrected visual acuity”- that's, you would not have the ability to see too after surgery, despite glasses or contacts, while you did with glasses or contacts before surgery.

The next side effects are possible, truly disappear with time. In rare situations, they might be permanent.

  • discomfort or pain
  • hazy or blurred eyesight
  • scratchiness
  • dry eye
  • glare
  • haloes or starbursts around lights, and issues with night driving that could require glasses
  • light sensitivity
  • small red or pink patches around the white from the eye.
