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.
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:
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.
