2000 witnessed the birth of Intralase technology. It was during this year that Intralase was first introduce and used as part of the laser eye treatment process. The innovation of Intralase was invented as there was a need to create a more accurate flap in terms of size, depth, and edge shape because this was the most important of the process and patients are often concerned most about this stage in the operation.

With Intralase engineering, a laser is used to create the flap instead of the more traditional mechanical microkeratome. A computer is used to guide the fematosecond layer which creates a layer of bubbles underneath the cornea, which is located on the front of the eye. These bubbles will then reveal the underlying stromal layer as a flap is peeled from the eye.

As preparation for the laser eye treatment, initial screening tests are performed to determine the limits used in the calibration of the fematosecond laser. The pre-op stage involves refraction and cornea mapping for the thickness and topography of the front of the eye, which is very similar to regular lasik procedures, up until the stage where the flap is created. Nursing the eye does not require stitches as the flap is replaced.

As for the post-operative complications, the same goes for Intralase laser eye treatment. Lubricants and eye drops are used to speed up the healing process. Clarity of the visual acuity also varies from the day of the surgery up until a few months though immediate results can be observed the following day. Chronic dry eyes can also affect a number of patients who underwent Intralase which would require them to use lubricants and overnight gels for an indefinite period of time. Reports of these complications are said to decrease over a period of six months.

Night time glares and haloes are also to be expected following Intralase. These are a bit more complicated as they prevent danger especially when a patient drives during night time as well as others who like watching sports live.

Despite all these laser eye treatment risks, studies have revealed the importance of undergoing Intralase techniques to acquire better visual acuity. Additionally, inconclusive evidence has not discouraged patients from choosing Intralase as a method to acquire clearer vision, making it one of the most popular options in lasik treatments. The 10 years of Intralase usage has established its value especially when it comes to the increased precision and safety in flap creation. The use of laser instead of a blade, which a microkeratome basically is, is considered a ground-breaking engineering in regular lasik eye surgery.
