10 EW NEWS & OPINION April 2012 Accessing the value of ASCRS information by John Ciccone ASCRS Director of Communications In the journal … April 2012 Middle prechop: Fracturing the middle portion of the nucleus André Berger, M.D., Inara Nogueira Contin, M.D., Graziela Nicoletti, M.D., Paula Fernanda Baltar Pazos, Henrique Santiago Baltar Pazos, M.D., José Álvaro Pereira Gomes, Ph.D., M.D. Investigators here described a technique that helps to reduce the amount of ultrasound power needed for phacoemulsification. The tech- nique, done prior to chopping, fractures the nucleus through the center of the lens. With this technique practitioners first create a continuous curvilinear capsulorhexis. They then inject an ophthalmic viscosurgical device into the anterior chamber. Next, using a back-and-forth move- ment, two modified cystotomes are inserted into the lens. To fracture the nucleus, a small amount of pressure from opposite sides is applied. The practitioner is then free to perform hydrodissection followed by phacoemulsification. Long-term architecture of clear corneal incisions using OCT Li Wang, M.D., Ph.D., Lena Dixit, M.D., Mitchell P. Weikert, M.D., Richard B. Jenkins, M.D., Douglas D. Koch, M.D. In this case series, investigators used Fourier-domain optical coherence tomography (OCT) on clear corneal cataract incisions to determine long-term wound-healing changes. On post-op day 1 in 37.1% of eyes Descemet's membrane detachment was seen. At the 1-3-month mark, this was still the case in 4.5% of eyes. After 3 months this was not seen. Also, on day 1, 85.7% of eyes showed post-op wound gape. For 31.% of eyes this was still evident at 1-3 months, but was no longer seen after that. At the 2-3 week post-op mark, posterior wound retraction appeared in 33.3%. By 1-3 years this was evident in 75% of cases, and after 3 years in 90.5% of cases. Investigators concluded that in the early post-op period practitioners could expect Descemet's membrane detachment and posterior wound gape, but wound retraction tended to be a later phenomenon likely resulting from long-term wound remodeling.

Depend- ing upon their refractive cylinder correction, patients were divided into three subgroups. Those in the low subgroup had cylinder correction of 0-1.25 D. Patients in the moderate group were between 1.50-2.75 D. Those with corrected astigmatism 3 D or greater were relegated to the high correction group. Investigators determined that for those with moderate cylinder more eyes that underwent LASIK were corrected with 0.5 D of the post-op refractive cylinder. However, for those who under- went LASIK who were in the high correction group, the refractive cylin- der error was significantly higher than in the toric pIOL group. Investigators did not see a change in post-op manifest refraction in either group. They concluded that following toric pIOL implantation, the stability of the refractive cylinder was as high as after LASIK. How- ever, for those in the moderate group, predictability of cylinder correc- tion was higher for those who underwent LASIK. On the other hand, for those with high refractive cylinder the toric pIOL had a higher predictability. he primary role of ASCRS is education. Every year, thousands of presentations on clinical topics such as cornea, glaucoma, intraocu- lar surgery, keratorefractive, pedi- atric, and retina are made at the ASCRS•ASOA Symposium & Con- gress, ASCRS Glaucoma Day and Cornea Day, and Winter Update. With all of this information, how can members access it? The ASCRS Media Center serves as the Society's online educational library. It is the vehicle by which ASCRS makes much of the educa- tional content it collects over the course of the year available to its members and the ophthalmic com- munity. As the leading organization for cataract and refractive surgery infor- mation, ASCRS is a conduit for an enormous volume of educational content in the form of papers, symposia, podcasts, films, webinars, posters, etc. The Media Center is ASCRS' way of providing ongoing access to that valuable material. As the ASCRS meeting has grown larger with many concurrent sessions, it's become more difficult for an oph- thalmologist to attend everything he or she would like to. The Media Center provides the opportunity to revisit those sessions that might have been missed. The same goes for the Winter Update meeting and for
