The Technology

Customising uniquely to your eye

Blackrock Clinic continues to invest in the latest generation of technologies, uniquely blended to drive better outcomes and greater satisfaction for you. In this section we aim to showcase the technology which partners the expertise of three of Ireland's leading ophthalmic surgeons, resulting in the best refractive service available. We are aware that some patients prefer to leave the science in the hands of their medical team, so if that is you, look away now!  

Did you know?

NASA's newest space telescope is calibrated by the same technology now used in LASIK! 

System iDesign AWS (Advanced Wavescan Studio)

What is it?

The iDesign Advanced WaveScan Studio System acts as the "brain" of the LASIK procedure, generating a high-definition scan which measures and maps irregularities of the eye that may impact vision. From these measurements the iDesign System creates an accurate and personalised LASIK treatment plan based upon the unique "blueprint" of each person's eyes.  

What does it do?

The System captures more than 1,200 microreadings of the eye, as well as identifying the shape of the cornea, its curvature, how light passes through the eye and pupil diameter under different lighting conditions − all in one, three-second scan that can be used to precisely correct vision.

IFS Advanced Femtosecond Laser

What is it?

The latest fifth generation IFS laser device allows the surgeon to have greater ability to fully customize a laser eye surgery procedure for each patient. 

What does it do?

It allows the surgeon to perform the procedure at an increased speed, with lower energy output, which helps reduce tissue inflammation. The IFS laser is fully customisable to every patient’s needs, and allows the surgeon to create a custom corneal flap in less than 15 seconds.

How does it do it?

The Intralase is the first of two lasers that are used to perform the procedure. It replaces the traditional blade, helping to eliminate danger to the patient, and reducing the need to make a cut during the procedure. This first laser is used to create the flap in the cornea.

The second part of the laser procedure is when the vision is corrected. 

IFS advanced femtosecond allows surgeons to have a higher degree of precision and customization than any other device or technology in the past. It allows:

  • A safer procedure by eliminating complications which were caused by bladed microkeratome.
  • Guaranteed precision with an all-laser solution for Lasik (no more cutting with a blade).
  • Dryness to be reduced after surgery.
  • Reduced levels of pressure placed on the eye, increasing the patient's comfort level and increasing the safety levels of performing the procedure. 
  • Thinner flaps, freeing up more tissue, allowing the surgeon to operate on patients with thinner corneas.

The chances of 20/20 vision are also increased when using this laser for Lasik. Not only does using this device cut the amount of time it takes to perform the procedure, it also increases precision, reduces post-surgery pain and inflammation, and allows the surgeon to fully customize the procedure, based on the patient’s individual needs for vision correction.

Star S4 IR Excimer Laser System

What is it?

An Excimer Laser System and iDesign Advanced WaveScan Studio System. 

What does it do?

The iDesign System determines the precise excimer laser treatment that is needed. The Laser System exposes the cornea to a sequence of precisely positioned ultraviolet light pulses, each of which vaporises a tiny amount of tissue. The Laser System treats nearsightedness by removing tissue from the centre of the cornea to flatten it and treats astigmatism by flattening the central cornea by different amounts at different angles to correct uneven focus.

How does it do it?

In addition to the laser itself, the Laser System includes an eyetracker that keeps the laser pulses correctly positioned on the cornea when the eye moves.

The iDesign System includes:

  • an aberrometer that measures and records the power of the eye as well as the size and position of the pupil,
  • a corneal topographer that measures the shape of the cornea, and 
  • treatment planning software that converts the data from the aberrometer into detailed instructions for the excimer laser treatment.
When is it used?

The Systems are intended for waveforont-guided LASIK (laser-assisted in situ keratomileusis) treatment of up to -11 diopters of power (D) of nearsightedness and up to -5 D of astigmatism. This information determines the precise excimer laser treatment that is needed.

The standard clinical refraction and the iDesign refraction must agree to within 0.625 D for myopia and 0.5D for astigmatism.

Oculus Pentacam HR

What is it?

The Gold Standard in Anterior Segment Tomography. This machine performs the second scan in laser assessment. It measures the corneal thickness, and will detect any cataract or persence of keratoconus.

What does it do?

Equipped with an automatically rotating Scheimpflug camera the Pentacam performs a complete measurement of the anterior eye segment in less than 2 seconds. A precise analysis of the central cornea is carried out in the process. During measurement extraneous eye movements are detected with a second pupil camera and automatically corrected during the calculation process. The software analyses and evaluates all the data acquired. These data then provide the basis for a three-dimensional model of the complete anterior eye segment.

How does it do it?

The Pentacam analyses the entire cornea, anterior chamber and crystalline lens. This includes an objective determination of the central radii, corneal asphericity, various coloured maps of curvature and elevation, chamber angle, chamber volume and chamber elevation as well as lens transparency. Tomography shows the individual levels of the anterior eye segment in a freely rotating model. Measurement is non-contact and entirely agreeable to the patient.

IOL Master 700

What is it?

Next generation optical biometer, which measures the eye if found to be not suitable for laser eye surgery, but could be suitabile for ICL.  

What does it do?

The IOLMaster 700 with SWEPT Source Biometry enables physicians to identify irregular geometries of their patients eyes at an early stage. In addition to optical biometry, it also offers OCT imaging across the entire length of the eye. 

How does it do it?

Imaging of the fovea in the macula lutea allows physicians to check for correct fixation. Compared with previous procedures, in which the measurement result was derived from an A scan curve, the image-based measurement with the IOLMaster 700 brings both physician and patient added safety, as the expected refractive outcome can be more reliably predicted.

This new device also simplifies the workflows prior to surgery. The Reference Image option eliminates the need for manual pre-operative and intraoperative marking of the astigmatism axis on the patient's eye before implantation of a toric IOL, as well as the necessity of manual data transfer. Both were previously necessary for alignment of the toric lenses.
