Lasik Surgery Risks


In general, LASIK surgery tends to have an excellent safety profile as well as some high success rates. Experts from the Singapore eye centre proclaimed that it was designed to treat various eye problems and sight related eye diseases such as astigmatism, myopia and hyperopia. As such, people with eye problems who wear glasses as a result of these eye diseases can be rest assured that if they undergo LASIK surgery, it will eliminate the need for contacts or glasses. As is the case with any other type of surgery, this type of surgery does come with potential risks and several side effects that you need to be aware of, before you choose to undergo the procedure. For instance, sight-threatening complications like significant loss of vision is extremely rare. Fortunately many complications and side effects can be resolved with additional medical treatment and surgery.

In this overview, we’re going to take a more detailed look at the complications and side effects that are associated with LASIK eye surgery as per information that was provided by the Singapore eye centre.


1) Dry Eye Syndrome 
Some individuals who undergo the procedure, experience a decrease in their body’s ability to produce tears. This in itself, can lead to blurred vision as well as a certain degree of discomfort. This ailment is referred to as dry eye syndrome. However, this ailment is typically temporary and can be easily alleviated with the utilization of eye drops.


2) Under-correction, Over correction Or Regression
Not every single case leads to 20/20 vision. In some instances, patients may still be required to utilize eyeglasses or contact lenses for certain activities. This is due to the fact that in some rare instances, the laser may remove too little or too much corneal tissue, which can lead to a visual outcome that is less than optimal.


3) Temporary Vision Disturbances And Discomfort 
In some instances patients say experience mild irritation as well as a certain degree of sensitivity towards light. However, this is normal and many medical experts proclaim that this should be expected. In fact, it is not uncommon for patients to experience glare, starbursts, halos, reduction in the sharpness of their vision and/or hazy vision as well.


4) Epithelial Ingrowth 
This is a term that is used to describe the scenario where cells from the outer portions of the cornea flow under the flap once the procedure has transpired. In most cases when this occurs, it does not lead to serious problems. However, in some cases – approximately 1 to 2% – patients may experience blurred vision as an end result.


5) Diffuse Lamellar Keratitis (DLK) 
This is a term that is used to describe inflammation that occurs under the LASIK flap. While it may be true that some inflammation is expected to transpire once the surgery has been completed. If it is not controlled, it can lead to vision loss. However, if DLK does occur, it can usually be treated with antibiotics or topical steroids.


6) Keratectasia Or Keratoconus 
This is a term that is used to describe the building of the eye’s surface. It can occur if too much of the tissue has been removed from the cornea during the procedure or if the cornea was weak, prior to LASIK.


7) Eye Infections 
Due to the fact that the corneal flap operates as a natural bandage, eye infections rarely do occur. However, it is worth noting that there is still a slim chance that some patients may experience an eye infection nonetheless.
