Laser Eye Surgery


Ophthalmologists perform laser surgery to correct eye-related problems. 

Types range from LASIK and even include surgical procedures like photorefractive keratectomy (PRK) or radial keratotomy (RK). 

Types of laser eye surgery are performed to correct vision problems, such as nearsightedness, farsightedness, astigmatism, and presbyopia. 

This article will tell you everything you need to know about laser eye surgery.


Let us begin.


Laser procedures

Laser eye surgery is a type of refractive surgery that corrects nearsightedness, farsightedness, and astigmatism. 

It works by using an excimer laser to reshape the cornea, helping to more precisely focus the retina. 

There are three types of laser eye surgery, namely LASIK, ReLEx SMILE, and surface laser treatments.


How does laser eye surgery work?

Laser eye surgery is an effective treatment in which a laser beam precisely molds the corneal tissue to its corrected shape during the procedure. 

Your surgeon then places tiny air bubble dots at specific locations on top of the cornea to preserve the particular curvature long-term while healing underneath occurs.


This process generally varies depending on whether you have laser-assisted in situ keratomileuses (LASIK) or photorefractive keratectomy (PRK).


What to expect from laser surgery

Everyone has a different and unique experience when it comes to laser eye surgeries. 

Also, the types of laser eye surgery used will significantly affect this process. 

Some people recover too quickly, while others take longer than expected or experience pain after the procedure. 

You must be fully aware of what may happen, so be sure to ask your doctor all questions before undergoing any laser treatment.


Before laser surgery

Your ophthalmologist will perform a complete eye exam before surgery. 

Diagnosis includes vision control, symptoms of infection, eye irritation, inflammation, high eye pressure, and dilated pupils. 

Also, because pre-existing problems like dry eyes can occasionally be exacerbated by laser, your ophthalmologist is well aware of how laser treatment can affect your vision.


The extent of your refractive error and whether surgery can repair your vision are also determined during this session.


During operation

Although there are different types of eye laser surgeries. This is the procedure for laser eye surgery:


  • You receive a few eye drops under local anesthesia.
  • Your eyelids will be locked in place to prevent you from blinking.
  • The suction will be placed over your eye to keep it from drifting.
  • The ring will put gentle pressure on your finger.
  • Your vision will start to fade at this point.
  • Your surgeon then creates a very thin flap in the corneal cells, either with a microkeratome or even a laser.
  • You must keep your eyes focused on a target light while a surgical laser performs your surgery.
  • The laser is a specialized device that has been configured with the readings from your eye.
  • The doctor then uses the laser to reshape your cornea.
  • You will hear a clicking sound when your ophthalmologist uses the laser.
  • After repairing the retina, your eye surgeon smoothes the edges and puts the flap back in place.
  • The flap adheres to the skin in 2-3 minutes and heals in place.

After surgery

Your eyelids may itch or blister for a few hours after the procedure. However, many patients are given specific eye drops to help with dryness and healing. For the most noticeable effects, be sure to use the eye drops correctly.

Your eyes should feel strong after several days and your vision should have improved.

Tips to Prepare for Laser Surgery

  1. Provide transportation to and from the health center.
  2. Leave your eye makeup at home.
  3. Remove the lenses from your face.

The bottom line


There are several types of laser eye surgeries available and they are a quick and easy treatment for those with vision problems. 

With the help of your doctor, you can finally stop wearing glasses or contact lenses to see better.
