LASIK Eye Surgery

October 23, 2013

LASIK (laser in-situ keratomileusis) is a very popular laser eye surgery technique. It is just one of many different techniques used to correct the vision of nearsighted and farsighted patients or those who have astigmatism.

All types of laser surgeries work by reshaping the cornea (clear front portion of the eye). This enables light to travel through it and focus properly on the retina located at the back of the eye.

Advantages of LASIK Eye Surgery

There are many benefits to LASIK surgery including:

  • A high success rate.
  • No pain – LASIK eye surgery patients experience very little pain postoperatively.
  • Vision correction – This is accomplished almost immediately or by the following day.
  • No stitches – LASIK surgery does not require the use of any stitches and/or bandages.
  • No adjustments – Any adjustments needed to further correct vision can be performed many years after LASIK surgery.
  • No glasses or contact lenses – Following LASIK eye surgery, the majority of patients experience a significant decrease in dependence on glasses and/or contact lens, and most do not wear them at all.

Possible Side Effects of LASIK Eye Surgery

Some LASIK patients suffer a minor degree of discomfort within the initial 24 to 48 hours following surgery. Side effects are rare but they can include:

  • Glare (difficulty seeing in bright light situations)
  • Appearance of halos around objects
  • Difficulty with nighttime driving
  • Fluctuations in vision
  • Dry eyes

LASIK Surgical Procedure

LASIK surgery is performed under a local anesthesia, administered in the form of eye drops. Typically, this procedure takes approximately ten minutes to complete. Patients may request a mild sedative if they are particularly nervous or anxious.  Patients must plan to have someone else drive them home following surgery.

At Kremer, a specialized bladeless instrument called an iFS femtosecond laser is used to create a thin flap in the cornea (although some practices may still use a microkeratome blade). The flap is peeled back and underlying tissue is reshaped using another laser. In this step, the surgeon utilizes custom wavefront 3D mapping (taken pre-operatively) to guide the laser, resulting in a treatment that is specific and unique to your eyes. The flap is then put back into place. The surgical procedure is now complete. Once the cornea is reshaped, it will focus light onto the retina correctly.

What to Expect Following LASIK Eye Surgery

After LASIK surgery, drops are prescribed to keep the eyes moist as well as to prevent the unlikely occurrence of infection and/or inflammation. These eye drops can cause a momentary burning sensation and/or blurring of vision. It is important not to use any other drops not specifically approved by the eye surgeon.

Postoperative healing is generally very quick. While a patient’s vision might be blurred for the first day or so, typically most notice a vast improvement in their vision within a few short days. A vision evaluation is done by the eye specialist within the initial 24 to 48 hours and at regularly scheduled appointments during the first year after LASIK surgery.
