Risks & Complications of Lasik Surgeries

The advancements in technology have introduced many techniques like Lasik, PRK, and Lasek that help achieve better success in eye operations. Designed to treat various optical issues such as astigmatism, myopia, and hyperopia, these procedures can even help you live without your glasses or contacts.

Although rare there are complications and risks associated with Lasik surgeries. The good news however is that most of these complications can be resolved through timely medical treatments or corrective surgeries. Nevertheless, it is always better to understand the risks, side effects, and limitations associated with Lasik before you undergo the procedure.

Not everyone may be a good candidate for Lasik surgery. Your eye doctor should ideally perform a thorough diagnostic eye exam to evaluate the thickness and shape of your cornea, your pupil size, refractive errors if any, and the moistness of your eyes, before doing your surgery. He may even ask about your medical history and overall health, and any medications that you may be taking. If this is not done, it may increase your chances of experiencing undesirable outcomes such as:

  • Large pupils
  • Irregular or very thin corneas
  • Unstable vision
  • High refractive error
  • Dry eyes

Since the introduction of Lasik about 20 years ago, many Americans have got their vision corrected through the surgery. As per reports expert Lasik surgeons have held the serious complication rates to below 1 percent. However, in very rare cases there have been certain complications, some of which are given below:

Vision disturbances and temporary discomfort

It is quite normal to expect mild irritation and light sensitivity during the first few days after a LASIK surgery. Patients have even complained of experiencing halos, hazy vision, glare, dry eye symptoms, reduced sharpness of vision, and even starbursts in low-light environments. However, most of these are temporary and fade away within a few months.

Irregular astigmatism

If the laser correction is not centered properly it can lead to irregular astigmatism where in the corneal surface would be unequally curved. As a result you may experience double vision or ghost images. Such conditions may need re-treatments or enhancement surgeries.

Epithelial ingrowth

There are cases where epithelial cells (cells from the outer layer of cornea) start growing under the flap after a LASIK surgery. If such condition is associated with any symptoms of discomfort or blurred vision, it might require an additional surgery to lift up the flap and extract those epithelial cells.

Diffuse lamellar keratitis (DLK)

An inflammation under the Lasik flap might cause DLK or what is known as ?Sands of the Sahara? condition. If left untreated, it might interfere with the healing process, leading to loss of vision. However, most patients with DLK respond well to antibiotics and topical steroids. In rare cases the flap might have to be lifted and cleaned to remove inflammatory cells that can cause damage.

Dry Eye Syndrome

50% of LASIK patients experience dry eye syndrome on a temporary basis. It can be treated effectively through some lubricating eye drops. These problems disappear once the eye is healed completely.

Achieving a 20/20 vision is quite rare after a LASIK surgery. However if the eyes do not respond to the surgery in a predictable way, it may necessitate an additional laser vision correction.
