What Is Lasik Surgery?

LASIK eye surgery is the best known and most commonly performed laser refractive surgery to correct vision problems. Laser-assisted in situ keratomileusis (LASIK) can be an alternative to glasses or contact lenses. During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eye (cornea) to improve vision. In eyes with normal vision, the cornea bends (refracts) light precisely onto the retina at the back of the eye. But with nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly, resulting in blurred vision. Glasses or contact lenses can correct vision, but reshaping the cornea itself also will provide the necessary refraction .

Why you should do Lasik Surgery?

LASIK surgery may be an option for the correction of one of these vision problems :

If you are planning LASIK surgery, you will probably be wearing glasses or contact lenses beforehand. Your ophthalmologist will talk to you about whether LASIK surgery or other similar refractive procedures work for you .

What conditions get treated with LASIK eye surgery?

LASIK helps with refractive errors. The most common refractive error conditions include :

  • Astigmatism: Astigmatism is a very common eye condition that causes blurred vision.
  • Nearsightedness (myopia): Myopia is a vision disorder where you can see objects clearly that are nearby, but not those that are far away.
  • Farsightedness (hyperopia): Hyperopia is the opposite of myopia. You’re able to see objects far away, but struggle with those up close.

What happens during LASIK eye surgery?

The process of LASIK eye surgery can be divided into five steps :

It’s understandable if the process of LASIK surgery makes you feel uncomfortable. No one likes to think about a laser touching their eye. You might find it reassuring to know that LASIK is proven to be a safe procedure and very few people have any long-term side effects .

What happens after LASIK eye surgery?

After your LASIK eye surgery your eyes might itch or burn, or it might feel like there’s something in them. Don’t worry, this discomfort is normal. It’s also normal to have blurry or hazy vision, see glare, starbursts or haloes around lights and to be sensitive to light. Since dry eyes are a common side effect of LASIK surgery, your ophthalmologist might give you some eye drops to take home. You might also be sent home with antibiotics and steroidal eye drops. Additionally, your ophthalmologist might also have you wear a shield over your eyes to stop you from touching your healing corneas, especially while you’re asleep. You’ll return to your ophthalmologist one day after your surgery to get your vision tested and make sure that your eye is healing .

What is LASIK Femto?

Femtosecond-assisted (Femto) laser in-situ keratomileusis (LASIK) is a type of laser eye surgery. This method, along with other refractory surgeries, is used to reshape the cornea of the eye in an effort to resolve vision problems. Keratomileusis, or the sculpting of the cornea as a way to correct refractive errors, was first developed in 1948Trusted Source using a small surgical tool with an oscillating blade called the microkeratome. This first method, using a mechanical tool, was known as anterior lamellar keratoplasty (ALK). In the late 1980s and early 1990s, technology for this procedure improved. The Femto laser, developed in the early 1990s, allowed surgeons to create the corneal flap used in LASIK with a laser rather than a mechanical cutting tool. After surgery, the flap can be replaced without sutures, allowing for quicker healing .

Frequently Asked Questions About LASIK Eye Surgery

Is LASIK painful?

Fortunately, LASIK eye surgery is not painful. Right before your procedure, your surgeon will place numbing eye drops into both of your eyes. While you may still feel a little bit of pressure during the procedure, you should not feel any pain.

how long to stay in iran for lasik eye surgery?

You should stay in the country for about 7 days to have surgery and prepare to fly home.

Do I need glasses after LASIK?

The majority of people who undergo LASIK surgery do not need glasses following their procedure. LASIK corrects the vision by reshaping the cornea with a specialized laser and these changes are permanent in the vast majority (96 to 99%) of our patients.

What if I sneeze during LASIK?

If you sneeze, move or blink during the treatment, the laser tracks your eye over one thousand times per second and adjusts the laser to make certain the laser is applied to exactly the right place. So, there is no reason to worry if you sneeze during LASIK.
