LASIK Technology

Blade-Free LASIK. No blade. No sutures. IntraLase – the latest laser surgery for vision improvement.

Thanks to the latest in laser technology, blade-less laser treatments are a reality. IntraLase is a path-breaking technology that has made this happen. Consider joining other patients who have already undergone laser vision correction surgeries with IntraLase.

How does it work?

A small flap is made in the cornea. Instead of a blade, laser light is used for this purpose. The IntraLase technology measures the position and depth of flap to be created. Scientifically positioned and streamed, the laser light creates minuscule bubbles with a diameter of one ten-thousandth inch. Subsequently, a corneal layer develops.

Introducing IntraLase – a revolutionary  LASIK solution.

In the iLASIK procedure, LASIK surgery is performed without the use of a blade. A corneal flap is created in a unique inside-out manner with the Intralase laser. The dimensions of the flap are customized to uniquely benefit the patient. During surgery, the eyes are fixated so as to stabilize their position. A low-pressure suction ring is used for the purpose of stabilizing the eyes and a laser beam is directed through it. Within moments, carbon dioxide and water bubbles are formed on the cornea which creates a smooth corneal surface. Next, the surgeon gently separates the tissue and laser vision correction procedure is performed. The corneal flap is folded back and the procedure concludes.

IntraLase is an accurate device with a 3-micron laser spot size capability. Even many LASIK-disqualified patients can be treated with IntraLase. Use of this device minimizes risks such as corneal abrasion and flap malfunctions such as thick, thin, partial and buttonhole flaps. An IntraLase created flap is “manhole” shaped. The vertical edges ensure that there is no flap slippage and wrinkling. It ensures that the flap is tightly wrapped and accidental rubbing of the eye during the healing phase will not dislodge the flap.

True Custom LASIK

Get the LASIK treatments with the best LASIK technologies

Studies submitted to the FDA have revealed that almost every patient that underwent laser eye treatment with this technology experienced tremendous vision improvement. This technology utilizes several inherent technologies used by NASA. One of them is the WaveScan. This guided technology which is utilized by powerful telescopes such as the Hubble is now used for LASIK eye treatment.

Advanced Customvue Technology – a step in the right direction

A WaveScan captures the unique eye details of the patient, every minute imperfection. The laser technology uses this information and completes a patient-specific treatment to correct the imperfections. The allows the patient to achieve their personal best vision, usually 20/20 or better!

  • Advance Customvue Technology treatment takes individualized wave scans and therefore is s truly customized treatment for your unique visual system. This is called a wavefront-guided treatment, true individual customization compared with the wave scan optimized treatment of other lasers which do not consider your wavefront.
  • Your night vision is significantly improved. As per reports submitted to the FDA, most patients were very satisfied with the treatment. More patients reported they were very satisfied with their night vision after Advance Customvue treatment compared to before with glasses or contact lenses when treated for mixed astigmatism (CustomVue™ Patient Information Booklet  0030-4671A).

The WaveScan Wavefront System

Given that each person’s vision is unique, the WaveScan Wavefront System is one such technology that detects such attributes in a patient’s eye. The data derived is used to make a wavefront – which is akin to a fingerprint. The WaveScan Wavefront System complements the Advanced CustomVue LASIK treatment. You have an accurate wave scan report that captures your eye details comprehensively.

Iris Registration Technology

There are significant changes to the measurement of the eyes when the patient is sitting up and lying down. When sitting up, the patient’s eye may rotate as opposed to a more stable eye position when lying down. The Iris Registration technology calculates this difference. It determines the measurement taken when the patient is sitting up and lying down and bridges the gap with an accurate analysis. It helps doctors obtain the correct measurement of the eye.

Patient movement on the table while a procedure occurs is a major concern at the Houston LASIK & Eye. Always catering to patient needs and making sure patient safety with comfort comes first, the doctors invest in the latest technology. Iris registration, part of iLASIK, comes as part of that process.


A patient’s eyes rotate in the socket when moving from a sitting to a lying down position. Iris registration technology compares the scan of an iris when the patient lies down to the scan of an iris when the patient sits up. When the patient lies down in front of the laser, the computer adjusts the treatment to account for any eye rotation that has occurred. This ensures the laser’s accuracy to deliver the specific treatment prescribed. Viewing the short video shows the issues.

The Process

The WaveScan computer of the iLASIK system acquires unique landmarks from your iris. These landmark features are again acquired when the patient lies down for LASIK just prior to commencing treatment. The computer compares these two data sets to accurately determine any degree of rotation. Iris registration is one way Houston LASIK & Eye makes each treatment unique and individualized for the patient. Because of this diligence to detail, the best outcome for the patient is possible.

3D ActiveTrak™ – A precision technology for precision LASIK eye treatments

An inherent technology and exclusive to the VISX STAR S4 IR excimer laser, the 3D ActivTrak™ is used by eye doctors to track 3-dimensional movements of the eyes during surgery. During surgery, patients may move their eyes. These eye movements can significantly impact the quality of surgery. Eye surgery precision is controlled and maintained with 3D ActivTrak™ that tracks the movement of the eye in all three directions. The laser beam utilizes this technology to accurately focus on the right spot on the eyes throughout the surgery.

The fact that the human eye is always moving has proven that this technology is instrumental in any laser eye surgery. Failure to apply the laser beam on the correct position on the eyes leads to surgery failure and even eye damage. Therefore the 3D ActivTrak™ Technology-enabled VISX STAR S4 IR is a blessing for thousands of patients. So if you are visiting a LASIK eye center for an eye treatment, you know what to ask for…3D ActivTrak™ – part of the iLASIK procedure.
