What does LASIK Surgery do?

Functions of LASIK Surgery

The full form of LASIK is "laser-assisted in situ keratomileusis." The term "in situ" denotes "in position" or "in place." The word "keratomileusis" indicates a well-known medical term for reshaping the cornea. LASIK surgery is a common and safe eye treatment for people who want to see without glasses or contact lenses. 

A less powerful laser shapes the cornea, the clear front part of the eye. With a proper cornea shape, light focuses better on the retina and enables clear vision. LASIK is a quicker process, often painless, and helps cure most common vision problems like nearsightedness, farsightedness, and astigmatism.

What is LASIK Eye Surgery?

LASIK eye surgery is one of the refractive eye surgeries where surgeons use lasers to fix problems with your vision. This surgery follows an outpatient procedure, which means patients can go home on the same day. With LASIK, refractive errors are corrected. The presence of this error prevents the eye from refracting (bending) light as it should. Refractive errors cause blurred vision. Thus, LASIK enables you to have a clear vision and experience a better quality of life. 

LASIK is a reliable treatment option for individuals who do not rely on glasses or contact lenses to improve their vision. After LASIK surgery, there is no longer a need to wear glasses or contact lenses. You might need them only when you are driving or reading at night. 

What does LASIK Eye Surgery do?

LASIK surgery modifies the shape of your eye cornea, allowing light to reach your retina correctly. Thus, you get a clearer vision. The outermost layer of your eye is the cornea. "It is made of transparent tissue and has a dome shape. 

It works together with another part of your eye, called the lens, to bend light before it reaches the retina. The retina is the back lining of your eye. When light reaches your retina, it sends electrical signals to the brain, which tells you what you are seeing. 

To get a clear vision, all parts of your eye need to function together. Consider an assembly line and represent the cornea responsible for making a product. If the cornea makes any mistake, the entire process gets disrupted, and the outcome fails. 

Similarly, when light enters through your eye, it passes the cornea first. If there is any error with the shape of your cornea, the light fails to enter and ends up taking the wrong path to reach your retina. 

Thus, by reshaping your cornea, LASIK lets light reach your cornea as it should and follow the right pathway to your retina. 

What are the Conditions LASIK Treat?

Here are the following conditions that LASIK treats:

• Nearsightedness (myopia): You can see objects if they are up close, but far objects appear fuzzy and blurred. 
• Farsightedness (hyperopia): With this, far objects are quite visible, but you face a struggle with close-up objects. 
• Presbyopia (age-related hyperopia): With age, the lens of your eye becomes less flexible. This makes it complicated to view things close to your face. Following a procedure known as monovision (blended vision), LASIK can make corrections in one eye for distance and another eye for seeing clearer objects nearby. This thereby enables you to improve your close-up vision and makes reading easier. 
• Astigmatism: This denotes a blurred vision while viewing any objects located at a distance. This happens because of an irregularly shaped cornea and takes place along with hyperopia and myopia. 

Does LASIK Fix Your Eyesight Permanently?

LASIK is a surgical procedure that will permanently reshape the cornea to help cure problems in vision, specifically nearsightedness, farsightedness, and astigmatism. The results are long-lasting in many people, and they no longer require glasses or contacts. Nevertheless, although corneal changes are permanent, LASIK does not impede the development of age-related vision change. 

In some cases, such as presbyopia and cataracts, these conditions can arise over time and require glasses for treatment. In some cases, vision may change gradually, and enhancement may be required. 

However, LASIK will permanently correct your initial refractive error, but it does not end the natural ageing process of your eyes. The surgery does not remove the potential for developing other eye problems. Therefore, regular eye check-ups are still important.
LASIK surgery is a helpful and effective way to improve eyesight for quite a few people. This program delivers fast results, inconveniences you very little with no painful stings and requires no dependence on glasses or contacts. Not everyone could have been happy with that, but it is what it is. Before choosing LASIK, make sure to have a consultation with your eye doctor to find out whether LASIK will be a reliable option.
