EW NEWS & OPINION 9 R egistration opened Oct. 12 for the 2012 ASCRS•ASOA Symposium & Congress in Chicago, April 20-24, 2012. The Opening General Session will feature Randall J. Olson, M.D., delivering the Binkhorst Lecture, the premier lecture of the ASCRS Annual Meeting, "Where are we on the road to optical perfection?" Dr. Olson's lecture examines those aspects of visual quality that most affect patient satisfaction after by John Ciccone ASCRS Director of Communications Registration open for ASCRS•ASOA Symposium & Congress Cataract surgery in rural central India Vinay Nangia, F.R.C.S., M.D., Jost B. Jonas, M.D., Rajesh Gupta, M.D., Anshu Khare, M.D., Ajit Sinha, M.D. The aim of investigators was to consider how widespread cataract sur- gery is in villages in central India and how these patients fare after cataract surgery. Investigators found that of 4,711 individuals with avail- able information concerning their lenses, just 3.4% had undergone cataract surgery. Age seemed to play a significant role in who opted for the procedure. Women were more likely to undergo the surgery, as well as those with diabetes. Investigators found that 63% of patients pre- sented after surgery with visual impairment generally as a result of in- correct IOL power. In 36% of these cases the complaint involved corrected distance visual acuity. This occurred as a result of posterior capsule opacification in 24% of cases, surgical complications in 21%, and age-related macular degeneration in 10.3%. Other factors leading to distance vision complaints included additional macular disorders in 4.3%, corneal opacities in 3.4%, and glaucoma in 2% of cases. Those who remained aphakic following surgery experienced 46.4% of the sur- gical complications compared with just 2% of those in the pseudopha- kic group. Investigators concluded that post-op outcomes may be markedly improved by better IOL power calculations and enhanced technique. Phacotrabeculectomy in pseudoexfoliation eyes Bradford J. Shingleton, M.D., Kristy B. Wooler, O.D., Carla I. Bourne, M.D., Mark W. O'Donoghue, O.D. In this comparative case series, investigators considered how eyes with pseudoexfoliation fared after undergoing combined uneventful phacoemulsification with implantation of a posterior chamber IOL and trabeculectomy compared with those who underwent the phacoemulsi- fication alone also without incident. Investigators found that mean IOP and glaucoma medication requirements were significantly reduced in those that underwent the combined procedure compared with pha- coemulsification alone. Statistical significance was maintained for 7 years after surgery. Those that had a higher mean pre-op IOP experi- enced a greater reduction after surgery. Ultimately, just 13.8% of eyes in the combined group required subsequent glaucoma procedures. Investi- gators concluded that greater, more longstanding reductions in IOP with fewer pressure spikes could be attained with combined procedures than with phacoemulsification alone. Visual performance of hybrid monovision Yoshihiko Iida, M.D., Ph.D., Kimiya Shimizu, M.D., Ph.D., Misae Ito, C.O., Ph.D. Investigators in this 32 patient case series assessed how bilateral cataract patients fared with use of a new technique dubbed hybrid monovision, involving use of a diffractive multifocal IOL in conjunction with a monofocal IOL. They found that in 62.5% of cases, near stereopsis fol- lowing lens implantation was in the normal range. In 18.8% of these cases however, patients were spectacle dependent. Patients attained mean binocular acuity of better than 0.1 logMAR at all distances. No waxy vision, akin to looking through water, was reported by any of the patients.
