There has been tremendous evolution and revolution of technological advancements in Lasik lasers in the field of eye vision correction surgery and enabled the surgery to be safer, predictable procedural outcomes and efficacy. The usage of the excimer laser in the surgery of Lasik has got its unique ability in stromal bed or corneal layer surface reshaping, with higher degree of accuracy.

Several Lasik laser technologies that approved by FDA are available  today. But, one technology may not be better compared to the other. The best and suitable Lasik surgery for patient, who is planning for correction of vision has to be selected on the basis of requirements, like the budget, degree of vision error, type of vision error, cornea thickness, size of pupil of the patient and expertise of the surgeon. Here the critical factors are the experience and skills of the Lasik surgeon, which are imperative, to evaluate and find the suitability of the Lasik accurately for final positive outcomes, compared to the smaller or subtle variations among several technologies of the Lasik laser that exist in today’s market.

All the Lasik laser systems do meet the criteria of effectiveness and safety, once these are approved by the FDA. The variation among these technologies can be the laser tracking system and laser beam delivering patterns during the procedure of the surgery.

The following laser beam types are employed in the Lasik machines that are approved by FDA, .

  • Slit Scanning Lasers
  • Flying Spot Scanning Lasers

The Wavefront Guided Lasik, Customized Lasik or Wavefront Optimized Lasik maps the irregularity or aberration in the optical system of the eye with a device. The device guides the beam of the lasers to proceed either with slit or spot scanning for the surface reshape of the cornea, so that sharper and clearer vision can be delivered. The best part of the wavefront technology is that it offers suitable and uniquely required customized correction of vision, that vary for each individual patient. The vision correction with the Wavefront Guided vision correction surgery is possible to be performed on both the flying spot scanning and slit scanning Lasik laser systems.

Since the FDA approved Lasik technologies are several , the critical factors would be the expertise, skills of the Lasik surgeons, eligibility, suitability of the Lasik surgery procedure, for better and positive outcomes of the Lasik surgery.
