The other physicians had no financial inter- ests to report. The European Society of Cataract and Refractive Surgeons (ESCRS) Congress opened Monday with the well-attended Combined Sympo- sium of Cataract and Refractive Societies. Surgeons from Europe, Asia-Pacific, Latin America, and North America discussed vision and optical quality after anterior segment surgery, refractive corneal surgery, monofocal and multifocal IOLs, and keratoplasty. New monofocal IOL Graham D. Barrett, F.R.A.C.O., president of APACRS, Perth, Aus- tralia, gave attendees the latest infor- mation about a new monofocal IOL designed to extend depth of focus and enhance modest monovision. A new clinical study on the ex- tended depth of focus (EDF) IOL began in February, with results showing that a patient gains 1-2 lines of focus with the lens, Prof. Barrett said. The lens, which was previously Editors' note: This Meeting Reporter contains original reporting by the EyeWorld news team from ESCRS 2012, Milan, Italy tested in an eye model and com- pared to spherical, aberration-free, and multifocal IOLs, preserves stereoacuity and enhances func- AC-supported phakic IOL High myopes experience improved quality of vision and increased point-spread function (PSF) under mesopic conditions after being im- planted with an angle-supported phakic IOL, according to an ESCRS speaker. Implantation of the lens also in- duced negative spherical aberration, said Simonetta Morselli, M.D., Verona, Italy. Dr. Morselli and colleagues measured quality of vision and vi- sual outcomes after implantation of the lens by using aberrometry data in a nonrandomized cohort study in Editors' note: Dr. Morselli has no re- lated financial interests. Femto incisions in PK Though a femtosecond laser has an "almost infinite number" of pro- grammable cut patterns in corneal transplants, the zigzag appears to be best because its wound becomes her- metically sealed, and the angled edge offers a smooth transition be- tween the donor and host tissue, ac- cording to one speaker. "This results in better visual acu- ity and faster recovery of vision," said Roger F. Steinert, M.D., Irvine, tional near vision when combined with modest monovision, Prof. Bar- rett said. The new IOL provides an addi- tional 1 D depth of focus compared to a standard negative aspheric monofocal IOL, but still meets the ANSI and ISO standards for optical quality required for a monofocal IOL, he said. A 1-month test with the Salzburg Reading Desk showed func- tional near and intermediate reading vision, Prof. Barrett added.

The mean total spherical aberra- tion Z(4,0) was −0.001±0.076 m pre- op and −0.13±0.11 m post-op (P≤.05). The mean PSF was 0.28±0.15 pre-op and 0.34±0.16 post-op (P<.05), according to the study abstract. The data is in press for the Journal of Cataract & Refrac- tive Surgery. "This phakic IOL induces nega- tive spherical aberration, thereby re- ducing positive ocular spherical aberration," Dr. Morselli said.
