New LASIK technologies

The LaserSoft solid-state laser (Katana Technologies GmbH) was presented as an innovation in corneal refractive surgery, which has been dominated by excimer lasers for many years.

“This laser has a very gentle impact on the cornea. It has reduced thermal effect and can be used on humid corneal surfaces. Refractive results are very good, and recovery is fast,” said Lucio Buratto, MD, who performed LASIK with the laser.

The eye tracker, he added, is fast and precise. The only drawback is a slightly longer surgical time, due to the small spot size.

“This system is already competitive on the market and is starting a completely new generation of lasers,” Dr. Buratto said.

The IntraLase FS laser and the Hansatome microkeratome (Bausch & Lomb) were described as the two most popular options for LASIK flap creation.

Dr. Buratto, who has used both systems, said he likes using the Hansatome but that he is going to use the IntraLase for refractive lamellar surgery.

Edward E. Manche, MD, said that the IntraLase has potential. It has the precision of computer-controlled technology and the advantage of creating the flap under low vacuum, he said.

He added that initial doubts about the safety of the device were unfounded.

“The only thing I do is use steroids for a slightly longer time, 7 days instead of 4,” he noted.

Speaking of new lasers. Does anyone have any information on the Isobeam laser? This is the double spot laser that Emory is/supposed to be using. It claims it can do a 10mm optical zone.

Nobody has enough corneal tissue for a true 10mm optical zone. It might do a 10mm "blend zone", which is not the same as a 10mm optical zone.
