    Dr. Jeff Machat, President and LASIK surgeon of Crystal Clear Vision, provides an overview of how LASIK works.

    Dr. Jeffery J. Machat: Hello! I am Dr. Jeff Machat, Medical Director of Crystal Clear Vision. Today I am going to discuss the most recent LASIK development. Over the past two decades there has been such an array of incredible advances with LASIK procedures, from eye tracking technologies that ensure that each pulse of laser light is precisely placed, to wavefront technology that has almost completely eliminated severe night glare and also allows surgeons to target prescription to 1/100th of a diopter to accuracy. In the near future we are looking forward to even more innovation and development in laser vision technology. Femtosecond corneal flap creation has largely supplanted bladed microkeratome traditional methods. And femtosecond technology is now being utilized to improve the safety and accuracy of cataract surgery.

    There has also been new development in the area of reading vision correction surgery. Everyone around the age of 45, some years earlier, some later, will need reading glasses, even if they never have required glassed in their lives. Laser procedures to create multifocal corneal patterns is not new, but the concern has been with the limited reversibility should the patient not be pleased with their visual result. Over the past two year an FDA trial has been underway on a new approach, one involving the laser insertion of a corneal implant known as the Kamra Inlay by AcuFocus. While not approved in the United States at this time, this procedure is approved in Canada, Europe, Asia, Australia, and South America.

    Kamra Inlay is based upon the pinhole effect and increases the depth of focus in one eye, improving reading vision, while preserving distance vision. Most importantly, the Kamra Inlay can be removed if the patient is unhappy. With tens of millions of people depending upon reading glasses, this reading implant could very well become more common than LASIK.
