Advanced Technology IOLs: Recommending the right IOL
Ocular Surgery News Europe Edition assembled a
panel of experts to review leading trends in advanced technology IOLs, and to provide perspectives on
recommending the right IOL for patients undergoing cataract surgery. The November OSN supplement is based on a
roundtable discussion held during the 2011 American Society of Cataract and Refractive Surgery Symposium
and Congress. Among the panelists are Richard L. Lindstrom, MD, and Michael Knorz, MD.

FreeVis specialists honored - Again.
November 2011 - As in the previous year, FOCUS magazine lists Michael Knorz, MD, and Armin Scharrer, MD, among the
TOP 39 German refractive and cataract surgeons.

Michael C. Knorz, M.D. presented Keynote Lecture at AAO's Refractive Surgery Subspecialty Day October 2011 - Michael Knorz presented results that highlight advantages of using the femtosecond laser during refractive cataract surgery. "Laser fragmentation requires less phaco power and doesn't disturb endothelial cells. The laser capsulotomy provides IOL centration and refractive predictability," Dr. Knorz said in his keynote address during the Refractive Surgerys Subspecialty Day at the 2011 Annual AAO Meeting in Orlando, FL. The laser is beneficial in capsulotomy, lens fragmentation, corneal incisions, and astigmatism correction.
Dr. Knorz said a recently published study has proven that IOL centration is better with the laser versus a manual capsulorhexis. Also, he said, there is a safety advantage with the laser platform.
"When we compare manual and laser phacoemulsification, we see about a 50% reduction in phacoemulsification power, as well as a 28% decrease in endothelial cell loss in the femto laser versus the manual technique," he said.
ESCRS 2011: Refractive adjustments after ocular surgery: To lift or not to lift?
September 2011 - Flap lift remains the standard enhancement after LASIK, as long as the flap is normal and the stromal bed is thick enough, according to a speaker at Monday's main ESCRS symposium, "Refractive Adjustments After Ocular Surgery." "Looking at the literature and talking to my colleagues, I would say that, today, under-the-flap is the preferred technique for enhancements, both for femtosecond LASIK and microkeratome LASIK," said Michael Knorz, M.D. , Germany. "The reasons are patient comfort and it is easily repeatable. Always lift the flap rather than recut. The rate of complications is much higher if you recut." Surface ablation is preferred if the stromal bed is too thin, if the flap is abnormal, or there has been a previous RK or corneal graft, Dr. Knorz said. Aspheric or custom ablation can be used to treat refractive errors, while custom ablation should also be used to treat higher order aberrations.
Femtosecond laser assisted capsulotomy - First results
August 2011 - More precise capsulotomy sizing and
centering can be achieved when using the femtosecond laser during cataract surgery / refractive lens exchange. Properly and regularly sized, shaped, and centered femtosecond laser capsulotomies resulted in better overlap parameters that help maintain proper positioning of the IOL.

Angle-supported phakic intraocular lens for correction of moderate to high myopia
Knorz et al conclude that the AcrySof Cachet phakic IOL, an angle-supported phakic lens, offers favorable refractive correction and predictability as well as acceptable safety in patients with moderate to high myopia. Knorz MC, Lane SS, Holland SP:

FreeVis introduces the Laser-assisted Refractive Lens Exchange
July 2011. The use of the femtosecond laser during the refractive lens exchange further increases its precision and safety. FreeVis uses the precision laser for the first four steps of the procedure: First, the laser liquifies the natural lens. Next, the laser is used to cut a circular opening into the lens capsule and a small incision in the periphery of the cornea. Finally, the femtosecond laser can also be used to correct an accompanying astigmatism.

Press Conference with Live Surgery in Mannheim
On February 3rd, 2011, Prof. Michael Knorz held a press conference to launch the KAMRA™ inlay at his practice in Mannheim, Germany. The event consisted of an educational presentation by Prof. Knorz,
a question and answer session, live surgery, a patient interview and fact sheet handout. Seven journalist and one radio station attended.
KAMRATM Inlay CE-certified in Europe (previously AcuFocus Corneal Inlay)
The inlay, a micro-thin piece of black polymer with a small opening its center, is designed to improve depth of focus to allow the eye to see near and intermediate objects more clearly, therefore decreasing dependence on reading glasses.

AcrySof phakic lens receives European Approval
The Acrysof phakic or "contact" lens (new name: Acrysof Cachet Phakic Lens) is used to treat nearsightedness from -6 to up to -16 dpt. It may also be indicated when corneal laser surgery cannot be performed or is at its limit, for example because the cornea is too thin. More...
