PARIS — In a series of 125 patients looking at the precision of capsulotomies created with the CAPSULaser compared with manual technique before routine cataract surgery, Erik L. Mertens, MD, FEBOphth, of Medipolis Eye Centre in Antwerp, Belgium, found the selective laser capsulotomy technique to be better in sizing accuracy, circularity and centration.

The difference in techniques was statistically significant in all three areas (all P < .05).

In the CAPSULaser (Excel-Lens) technique, the laser is selectively absorbed in a trypan blue-stained capsule that creates a strong, tear-resistant capsulotomy edge, according to Mertens’ presentation at the European Society of Cataract and Refractive Surgeons meeting.

Regarding the secondary endpoint of safety, there were no adverse events in any of the patients. Both the laser and the manual technique were the same, he said.

“We also observed that the CAPSULaser capsulotomies were 100% free-floating and covered the IOLs 360° after surgery,” Mertens said.

The laser technique protocol is important for consistent results, Mertens said. After the eye is prepared in a normal manner as for cataract surgery and then prepared with trypan blue for the capsulotomy, the laser treatment duration lasts approximately 0.34 seconds for a 5-mm capsulotomy.

“The workflow and clinical time are equivalent to manual rhexis,” Mertens said. – by Patricia Nale, ELS
