Side Effects / Possible Complications


Temporary Side Effects

The following side effects are possible but usually disappear over the weeks immediately following surgery. In rare situations they may persist.

  • Dry eyes - Some people experience mild to moderate dry eye symptoms after Lasik for 1-3 months. Use of lubricating eye drops are recommended for all patients.
  • Hazy or blurry vision - Some eyes develop a faint haze in the healing stage, this may be noticed up to 3 months and fades away by 6 months.
  • Light sensitivity - Increased photo sensitivity occurs on the first few days and sunglasses are recommended.
  • Halos / night vision problems - In the first few weeks following surgery some people can experience halos around lights.
  • Gritty feeling
  • Red eye(s)
  • Transient over-correction - A small over-correction is expected particularly for high corrections and Hyperopia. It usually regresses in the first 3 months, if it persists an enhancement may be appropriate.


Risks and Possible Complications

Every precaution will be taken to avoid complications. However, every surgical procedure carries an element of risk and a 100% successful outcome cannot be guaranteed.

Complications vary in severity but as a general rule significant complications with Laser refractive surgery are very rare. The list below is not intended to be extensive, but rather it is a list of the complications we think you should know in order to make an informed decision about undergoing laser refractive surgery.


May occur, or astigmatism requiring further treatment. This is known as an Enhancement and may be required in 3-5% of patients. Cost is covered by Laservision up to the first 2 years.

Light-sensitivity: Some patients who undergo laser refractive surgery may find that they are more sensitive to light than they were before the operation. They may also develop increased glare and may experience halos around lights. This may affect their ability to drive, particularly at night. These changes are rarely permanent or debilitating.

Reduced vision: In a few patients despite apparently successful surgery the vision is not as good as expected and patients may find their best corrected vision, i.e. with glasses or contact lenses, is not as good as it was before the surgery. There may not be any simple explanation for this.

Infection: Extremely rare with Laser surgery with prophylaxis carried out at the time of surgery and antibiotic drops used post operatively.

Raised IOP (Intra-Ocular Pressure): Prolonged steroid use can cause raised IOP in some patients, usually only if steroid drops are used for more than one month. This is monitored by your eye care practitioner at your post-operative visits.


Ectasia: Thinning and distortion of the cornea. Every care is taken to exclude 'at risk' patients and corneas.


Flap Related Complications

Inability to create a flap suitable for Laser surgery very rarely happens. In such a situation, once the cornea settles, surgery is rescheduled. The corneal flap is not 'glued down' but slowly heals into place over time. Particularly in the first 24 hours, it may be prone to wrinkling, puckering or dislodgement - it can be easily repositioned by the surgeon. Shields are put in place to avoid rubbing of the eyes during the first 12 hours.


Laservision’s aim is to provide safe, proven and effective procedures using advanced technology and the highest standard of care for all those treated at the clinic.
