Our bodies become more susceptible to wear and tear as we get older – our joints become frailer, memory isn’t as sharp, and vision becomes blurry. For these issues, there are various solutions to focus on them. One of the more pioneering procedures to ever appear in the last few decades is laser eye surgery.
What is a Laser Eye Procedure?
Many people ask about laser eye surgery costs because it is a very sought-after procedure since it is quick, safe, and painless. During a LASIK procedure, the LASIK surgeon creates a flap of tissue over the cornea and peels it back to have access to the cornea. Afterward, the laser will beam right into the eye to reshape the cornea, which is how the vision improves.
The whole procedure doesn’t take more than a minute. Once it is completed, the patient is given eye drops to ensure that their eyes don’t go dry.
Typically, LASIK surgery patients recover within 24 to 48 hours. This all depends on a person’s healing capabilities, but you can have peace of mind that you won’t have to wait a long time until you can see the world clearly again.
Who Should Get LASIK Surgery?
People who are sick and tired of wearing eyeglasses or contact lenses may want to go through LASIK surgery. This is a type of refractive eye surgery.
For the most part, many people who get laser-assisted in situ keratomileusis (LASIK) eye surgery attain 20/20 vision or better, which is sufficient for most activities. However, most people will still require glasses for driving at night or reading as they age.
LASIK has an excellent performance record. If there are ever complications that result in a loss of vision, they are rare, and many people are happy with their results. Specific side effects, especially dry eyes and temporary visual disturbances (such as glare), are fairly common. However, these usually clear up after a couple of weeks or months, and a minority of people think of them as long-term issues.
A person’s results rely on their refractive error and other factors. Those with mild nearsightedness usually have the most success with refractive surgery. Individuals with a high level of nearsightedness, farsightedness, and astigmatism have less predictable results.

What Happens During LASIK?
There are quite a few variations of laser refractive surgery. LASIK is the most sought-after and most commonly performed eye surgery. Most of the time, the term “LASIK” is used to indicate all types of laser eye surgery.
Normally, images are focused on the retina that’s in the back of the eye. When it comes to nearsightedness, farsightedness, or astigmatism, they finish up being focused either in front of or behind the retina, ending in blurred vision.
- Nearsightedness (myopia) is a condition that lets you see objects nearby clearly, but objects that are far away appear blurry. When your eyeball is a little bit longer than normal or when the cornea curves too sharply, light rays focus in front of the retina and blur distant vision. A person can see objects that are close more clearly, but not those that are far away.
- Farsightedness (hyperopia) is a condition that lets you see objects far away clearly, but nearby objects are blurry. When you have a shorter than average eyeball or a cornea that is too flat, light focuses behind the retina rather than on it. This blurs near vision and occasionally distant vision.
- Astigmatism results in overall blurry vision. When the cornea curves or flattens unevenly, the outcome is astigmatism, which interrupts the focus of near and distant vision.
Normally, blurry vision is corrected by bending (refracting) light rays with glasses or contact lenses. Nevertheless, reshaping the cornea (the dome-shaped transparent tissue at the front of your eye) itself can provide the necessary refraction and vision correction
Prior to a LASIK procedure, your LASIK eye surgeon will determine the detailed measurements of your eye and assess the eye’s overall health. Your eye surgeon may ask you to take a mild sedative medication just before the procedure.
Eye-numbing drops will be administered once you are lying comfortably on an operating table. Then he or she will use a unique type of cutting laser to alter the curvature of your cornea accurately.
Whenever the laser beam sends a pulse, a very small amount of corneal tissue is taken off, allowing your eye surgeon to flatten the curve of your cornea or make it steeper.
Typically, an eye surgeon creates a flap in the cornea and then lifts it before reshaping it. Also, there are variations that involve a thin flap to be raised or no flap is used at all. Nonetheless, each technique has its pros and cons.
What are the Kinds of Laser Eye Procedures?
Every LASIK eye surgeon may specialize in specific types of laser eye procedures. Their differences are usually small, and none are clearly better than any others. Depending on your individual situation and preferences, you may consider:
- 1. Laser-Assisted in Situ Keratomileusis (LASIK): It’s the most commonly performed eye laser surgery, LASIK involves making a partial-thickness corneal flap and utilizing an excimer laser to ablate the bed of the cornea. The flap is then put back into its original position. Discomfort after surgery is very little, and vision recovery usually takes place in 1 to 2 days.
- 2. Photorefractive Keratectomy (PRK): With PRK, instead of creating a flap, the top surface (epithelium) is scraped away. This corneal abrasion takes three or four days to heal, and the outcome is moderate pain and blurred vision in the short term.
It was considered that these disadvantages were canceled out by the theoretical advantage that PRK was safer for those who are more likely to be stuck in the eye — for instance, those involved in law enforcement, military, or contact sports. However, even with standard LASIK, the risk of eyeball rupture is still very low, so there is probably no significant advantage with PRK. Additionally, LASIK is a better option than PRK for correcting more severe nearsightedness (myopia).
3. Laser-Assisted Subepithelial Keratectomy (LASEK): LASEK is no different from LASIK surgery, but the flap is made by using a special cutting device (microkeratome) and exposing the cornea to ethanol. The procedure lets the surgeon remove less of the cornea, making it a good option for those who have thin corneas. LASEK does not have any considerable advantages over LASIK for individuals at greater risk of eye injuries.
4. Epithelial Laser-Assisted in Situ Keratomileusis (epi-LASIK): In an epi-LASIK procedure, your laser eye surgeon separates the epithelium from the middle part of the cornea called the stroma) using a mechanized blunt blade device known as an epikeratome and reshapes the cornea with a laser. This procedure is similar to LASEK.
5. Small-Incision Lenticule Extraction (SMILE): This is a more contemporary type of refractive surgery that allows the eye surgeon to reshape the cornea. To do this, the surgeon uses a laser to make a lens-shaped bit of tissue known as the lenticule which is located below the cornea surface. When the lenticule has been used to reshape the cornea, it is then removed through a very small incision.
6. Intraocular Lenses: A laser eye surgeon can use surgically inserted corrective lenses in the eye, which are also known as intraocular lenses) to enhance vision. It’s normally carried out as part of cataract surgery, which involves removing the old, cloudy natural lens. Additionally, it may be an alternative to LASIK for older adults who may require cataract surgery in the future.
Younger people with high levels of nearsightedness that cannot be properly treated with corrective lenses may be offered intraocular lenses. However, these are not a typical options for most people.
7. Bioptics: Bioptics uses one or more techniques, such as intraocular lenses and LASIK, to treat nearsightedness or farsightedness.
