What Are The Side Effects Of Laser Eye Surgery?
Laser eye surgery procedures have an excellent patient
safety record and a significant success rate and thankfully, reports of
sight-threatening complications resulting from laser eye surgery are very rare.
When side effects do occur, they can normally be resolved through advanced
surgical procedures or medical treatment.
Like any typical surgery, potential risks, unforeseen
side effects and limitations cannot be ruled out prior to undergoing the
surgery. By choosing an experienced and skilled laser eye surgeon, you’ll
minimize the risks and complications significantly, and this will enable you
achieve the best possible visual outcomes. The risks vary between the types of
surgery with the most common (LASIK, LASEK and PRK) which are all designed to
treat various defects including myopia, hyperopia and astigmatism having very
small risks.
Laser eye surgery risk factors and eligibility
Not everyone is a candidate for laser eye surgery. A
series of conditions and anatomical factors can aggravate the risk of
undesirable outcomes or limit optimal laser eye surgery outcomes. You may
be unsuitable for laser eye surgery due to the following factors:
- · Corneas which are too thin or irregularly shaped
- · Heightened refractive error
- · Existing unstable vision
- · Dry eyes
- · Age limitations (must be 18 or over)
- · Physiological factors such as pregnancy
- · Existing degenerative disorders
- · Laser eye surgery side effects and complications
Possible Side Effects & Complications After Laser
Eye Surgery
Millions of people n the UK have had laser eye
correction since its introduction over 20 years ago. The procedure has always
been done by experienced laser eye surgeons in private clinks across the UK and
luckily complications are rare.
However, here are some of the side effects and
complications that have been reported:
Temporary visual disturbances and discomfort: Occurs
during the first few days after surgery, and manifests in mild irritation and
light sensitivity. Patients have also reported halos and glares especially when
driving at night, episodes of dry eyes, hazy vision and reduced acuity of
vision. Since these problems are not permanent, they usually disappear within
three to six months

Flap complications: Laser eye surgery involves procedures such as LASIK whereby a flap is cut on the front surface of the cornea. The flap is lifted during surgery to allow for corneal reshaping and later replaced using natural bandage.
Dry Eyes: Often reported by patients who have
undergone LASIK laser surgery as a result of decreased tear production
culminating in eye irritation and vision blurring. Up to half of laser eye
surgery patients experience varying levels dry eye syndrome. Being a temporary
problem, dry eye syndrome can be corrected by application of eye drops to
lubricate the surface of the eyes. As healing continues, dry eye syndrome also
disappears.
Remarkable undercorrection, overcorrection or
regression: In many instances, side effects of laser eye surgery manifest
in the perception of objects in the long term. After laser eye surgery, not all
patients will achieve 20:20 vision, and it may still be necessary to use
glasses and contacts in some cases. In case the laser removes too much or too
little tissue from the cornea, or your eyes’ healing is disturbed, the eventual
visual outcome may not be optimal as expected. The less-than-perfect surgical
are often as a result of your eyes failing to respond appropriately to laser
eye surgery as predicted. Similarly, your eyes may work optimally a few weeks
after surgery, but over time you develop regression due to over-healing. Is
directly related to
Eye infection: Although rare, laser eye
surgeons attest that the likelihood of infections occurring is high in
surgeries that use surface ablations such as PRK. By using a natural bandage
after surgery, a more sterile environment is created that foster proper healing
after eye laser surgery.
