All You Need To Know About LASIK Eye Surgery

LASIK Eye Surgery

LASIK, which stands for laser in-situ keratomileusis, is a popular surgery used to correct vision in people who are nearsighted, farsighted, or have astigmatism.

All laser vision correction surgeries work by reshaping the cornea, the clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. LASIK is one of a number of different surgical techniques used to reshape the cornea.

What Are the Advantages of LASIK Eye Surgery?

LASIK has many benefits, including:

  • It works! It corrects vision. Around 90% of patients will have their desired vision after LASIK. An enhancement can further increase this number.
  • LASIK is associated with very little pain.
  • Vision is corrected nearly immediately or by the day after LASIK.
  • No bandages or stitches are required after LASIK.
  • Adjustments can be made years after LASIK to further correct vision.
  • After having LASIK, most patients have a dramatic reduction in eyeglass or contact lens dependence and many patients no longer need them at all.

What Are the Disadvantages of LASIK Eye Surgery?

Despite the pluses, there are some disadvantages to LASIK eye surgery:

lasik

  • Changes made to the cornea cannot be reversed after LASIK.
  • LASIK is technically complex. Problems may occur when the doctor cuts the flap, which can permanently affect vision.
  • LASIK can rarely cause a loss of “best” vision. Your best vision is the highest degree of vision that you achieved while wearing your contacts or eyeglasses.

 

What Are the Potential Side Effects of LASIK Eye Surgery?

Some patients experience discomfort in the first 24 to 48 hours after LASIK eye surgery. Other side effects, although rare, may include:

  • Glare
  • Seeing halos around images
  • Difficulty driving at night
  • Fluctuating vision
  • Dry eyes

 

How Should I Prepare for LASIK Eye Surgery?

Before LASIK eye surgery, you will meet with a coordinator who will discuss what to expect during and after the procedure. During this session, your medical history will be evaluated and your eyes will be fully examined. Likely initial tests include measuring corneal thickness, refraction, corneal mapping, air pressure, and pupil dilation. Once you have gone through the initial evaluation, you will meet the surgeon, who will answer any questions you may have. Afterwards, you can schedule an appointment for the procedure.

If you wear rigid gas permeable contact lenses, you should not wear them for at least three weeks before your evaluation. Other types of contact lenses shouldn’t be worn for at least three days prior to the evaluation. Be sure to bring your eyeglasses to the surgeon so your prescription can be reviewed.

On the day of your surgery, eat a light meal before going to the doctor and take all of your prescribed medications. Do not wear eye makeup or have any bulky accessories in your hair that will interfere with positioning your head under the laser. If you are not feeling well that morning, call the doctor’s office to determine whether the procedure needs to be postponed.

What Happens During LASIK Eye Surgery?

During LASIK eye surgery, an instrument called a microkeratome or femtosecond laser is used to cut a thin flap in the cornea. The cornea is then peeled back and the underlying corneal tissue is reshaped using another  laser. After the cornea is reshaped so that it can properly focus light onto the retina, the cornea flap is put back in place and the surgery is complete.

LASIK is performed while the patient is under local anesthesia in the form of eyedrops and usually takes about 10 minutes to complete. Patients may also request mild sedation. Plan to have someone drive you home after surgery.

What Should I Expect After LASIK Eye Surgery?

Your eyes will be dry even though they do not feel that way. Your doctor will give you prescription eye drops to prevent infection and inflammation and eyedrops to keep your eyes moist. These drops may cause a momentary slight burn or blurring of your vision when you use them. Do not use any eye drops not approved by your eye doctor.

Healing after LASIK eye surgery usually occurs very rapidly. Vision may be blurry and hazy for the first day, but most patients notice improved vision within a few days of surgery.

Specific follow-up after the surgery varies from one surgeon to another. You will revisit the doctor for an evaluation 24 to 48 hours after LASIK eye surgery, as well as at regular intervals within the first six months.
