LASIK Eye Correction Surgery & Treatment

  • LASIK laser eye surgery is available at our London, Birmingham and Leeds clinics
  • The LASIK procedure at Accuvision takes just a few minutes per eye
  • Accuvision offer fully customised LASIK treatment plans due to their advanced technology platform and unrivalled expertise
  • No pain is expected from a LASIK laser eye surgery procedure
  • The patient is kept informed throughout the LASIK eye surgery procedure

The LASIK procedure (laser in situ keratomileusis) has become the most popular eye treatment for laser vision correction. It is performed using anaesthetic eye drops on an outpatient basis. A typical LASIK eye treatment takes about 3-4 minutes to perform and no pain is expected. Generally both eyes, if indicated can be treated at the same visit.

All LASIK eye treatments performed at Accuvision incorporate sub 100 micron thin flap technology and the revolutionary WaveLight Allegretto Eye-Q laser platform. This ensures the highest levels of safety and optimal visual outcomes for our patients. We routinely treat patients with high prescriptions or other complex cases with this technique.

 

LASIK procedure

LASIK eye treatment is comprised of two stages: firstly, a thin, hinged flap of corneal tissue is created at the surface of the cornea using a highly sophisticated, precision engineered, fully automated device for creating predictable sub 100 micron flaps. This specialised instrument is called a microkeratome. This stage takes a few seconds and the patient will notice a pressure type sensation and a temporary moment of dimming of vision.

The flap is gently lifted and placed to the side, exposing the stroma of the cornea ready for the application of the laser (the second stage of the treatment), to re-shape the cornea. The laser vision correction takes only a few seconds and is completely computer controlled for speed and accuracy. The patient simply needs to observe a flashing light above. The flap is then re-positioned onto the cornea and a protective contact lens is placed over it to help the flap settle after treatment. The protective lens is usually removed at the first post-operative visit the following day.

The excimer laser is programmed using the diagnostic data taken during your consultation to reshape the cornea and thereby alter its refractive state to improve your vision after LASIK laser eye surgery.

Some patients may experience slight irritation after LASIK eye treatment and your eyes may be more sensitive to light and watery, but these effects usually only last a few hours. Many patients notice an improvement in their vision immediately after surgery, although it may take a few days for the maximum benefit to be experienced. It is common to experience mild fluctuation in vision, dryness of the eyes and mild halo effects around lights as the cornea heals and the refraction stabilises, but generally these effects are only temporary.

Most patients are able to return to work and drive 48 hours after LASIK eye treatment.

Although the flap seals and adheres within hours of the procedure, it is important that patients are gentle with their eyes and avoid rubbing or pressing on their eyes for a week or two to avoid the small possibility of displacing the flap. It is also important to use the antibiotic / steroid eye drops provided and any artificial tear lubricants as instructed to minimize the chance of any infection and to control inflammation and dryness.

 

Advantages of LASIK laser eye treatments:

  • Highly predictable/accurate optical outcomes after LASIK laser eye surgery
  • Minimal post-operative discomfort
  • Rapid visual rehabilitation following LASIK eye treatment
  • Wide range of treatable prescriptions (depends on factors such as corneal thickness, corneal shape)
  • Minimal risk of scarring

Possible disadvantages of LASIK laser eye treatment:

  • Small risk of complications involving the corneal flap
  • Not appropriate to perform LASIK eye surgery on eyes that may be bio-mechanically compromised

LASIK eye treatment can be used with the full range of customised laser eye treatment options offered by the WaveLight Allegretto laser including wavefront optimised/guided or topography guided, depending on each case presentation.

We will guide you through the most appropriate eye surgery solution for your particular case at your consultation. For more information about these procedures please give our consultants a call on 0330 300 2020 or book yourself a free consultation.
