Our Lasers

Laser eye surgery is based on reshaping the cornea to correct short sight, long sight and/or astigmatism.

At Moorfields we have access to the latest laser technologies including the ZEISS VISUMAX femtosecond laser for SmILE only procedures, the Schwind Amaris 750s and also the VISX S4 Excimer Lasers and the INTRALASE™ 150 femtosecond laser.

The ZEISS SmILE procedure is the latest  development in laser vision correction. It combines the extensive experience and superior safety of vision correction treatments such as LASIK, with the additional benefits of using just one small minimally invasive “flap-less” incision. This enables maximum protection of healthy tissue, increased comfort immediately following treatment and short healing times. SmILE, which stands for Small Incision Lenticule Extraction, is an excellent option for younger patients with higher levels of shortsightedness that are contact lens intolerant or for those wishing to return quickly to contact sports after treatment.

How does it work?
The laser is used to cut a thin lens shaped pattern through the corneal tissue very close to the corneal surface. This lens shape (lenticule) is removed through a small incision also created by the laser. The lenticule dimensions are tailored to correspond to the sight correction required, and most combinations of short-sight and astigmatism can be corrected.

  • In SMILE a lens shaped piece of corneal tissue (the lenticule) is removed intact to achieve sight correction, whereas in LASIK the lenticule is vaporised by the excimer laser.
  • There is no corneal flap in SMILE, and therefore no risk of LASIK flap dislocation.
  • SMILE is good options for patients seeking an early return to contact sport, with dry eyes and it is believed to affect the overall strength of the cornea less than LASIK..
  • LASIK and surface laser treatments may be more accurate than SMILE for lower myopic corrections; SMILE may be more accurate for correcting higher levels of short-sight.

Moorfields Eye Hospital is a flagship location for manufacturers of laser equipment, and therefore we are able to select from all the leading excimer laser platforms and renew our equipment every 3 years. Mr Maurino uses currently the above lasers and especially the Schwind Amaris 750S excimer laser platform, which combines the best options for wavefront guided and aberration free laser treatments with improved eye tracking, iris recognition software and therefore ultimately the ability to create an ideal post-treatment corneal shape.

Information from the scans taken at Consultation can be programmed into the excimer laser with the aim of reshaping the cornea to try to eliminate your spectacles or contact lenses dependence.

Current wavefront optimised and guided laser treatments do not routinely produce better vision than spectacles and contact lenses, but they have two benefits over laser eye treatments based solely on spectacle prescriptions:

• Wavefront treatments are less likely to result in surgically induced increases in higher order aberrations (i.e. the corneal shape produced by a wavefront guided treatment is closer to the ideal natural shape of the eye).

• Wavefront  surgery is less likely to cause night vision problems or a reduction in other elements of visual performance. Night vision can improve in patients after wavefront-optimised treatment.

Current wavefront guided laser treatments do not routinely produce better vision than spectacles and contact lenses, but they can help to improve overall visual quality and treatment accuracy in the right patients. Your suitability for wavefront guided treatment will be discussed with you at your preliminary consultation.The wavefront scanning and wavefront optimised excimer laser refractive surgical systems used by Vincenzo Maurino at Moorfields Eye Hospital are the latest generation and are upgraded regularly to ensure our patients benefit from the best technology advancements.

Femtosecond Laser LASIK Flap creation

In modern LASIK, two lasers are used. First, a femtosecond laser is used to trace a 3D pattern of microscopic gas bubbles through the cornea to create a thin protective flap. The tissues beneath are then reshaped using a computer controlled excimer laser before the protective flap is replaced. In essence, the cornea is reshaped without surface damage. The femtosecond laser used at Moorfields Eye Hospital is the  the 5th-generation (latest) INTRALASE™ 150 femtosecond laser.  Mr Maurino uses this laser for LASIK flap creation and also corneal transplant surgery. Over 5 million LASIK Flap procedures have been performed to date with IntraLase® Technology making it the femtosecond technology of choice worldwide. The Intralase provides the ideal combination of advantages: minimal disruption of corneal architecture, stronger flaps, fewer possible complications plus faster visual recovery.
