For those of you frustrated with cumbersome vision correction glasses and expensive contact lenses, correcting your vision with laser surgery is a popular option. A quick and relatively safe procedure, laser surgery is being increasingly preferred worldwide, for eliminating the hassle of external vision correction elements from their lives. In fact, this procedure also significantly improves your vision and enables you to enjoy activities that you cannot do while wearing glasses on contact lenses.
However, if you are planning to undergo laser surgery for vision correction, you need to be aware of certain risks that accompany this medical procedure.
Night vision may suffer
“In anything but extremely bright daylight, I am visually impaired by starbursts, halos, and multiple ghost images, because of LASIK done on my 8mm pupils” – LASIK patient Mitch Ferro, testifying before the FDA Ophthalmic Devices Panel. This is one of the serious downsides of laser eye surgery, which you need to consider seriously, before opting for this vision correction procedure.
Continuously bothering dry eyes
The most common complication after laser eye surgery, dry eyes may adversely affect the post-operative healing process. In extreme cases, they may lead to refractive regression and corneal erosions. The prime cause of this syndrome is damage to the corneal nerve during surgery. If you already have a dry eye problem, you should not opt for laser eye surgery.
High chances of corneal infection
While surgeons take every possible care to avoid the risk of corneal infection after surgery, 1 in about 5000 laser surgery patients are exposed to this risk. Extremely inconveniencing, and at times painful, this infection should be treated at the earliest. Any delay in treatment can result in partial vision loss.
Corneal Haze may set in
In extreme cases of post laser surgery complications, your vision may start becoming hazier with passing time. Haloes around lights or seeing double, are the key issues which arise shortly after the operation. Further laser treatment may be required to correct this condition. In extreme cases, this can also become untreatable and the person will have to live with it for a lifetime.
Loss of sharpness in vision
Following laser correction surgery, some patients are still unable to see everything with full clarity. For example, the bottom lines of the eye chart may not be readable, as would have been the case before the surgery. In some cases, this problem may remain permanently.
If you are put on topical steroid eye-drops for treating any post-surgery complications, there is a strong possibility of cataract formation.
If there is a serious corneal abscess post-surgery, or if blood vessels were already existing in the cornea, then there is a strong likelihood of corneal vascularisation, where blood vessels begin growing into the cornea.
