UPDATE 15 In the journal Corneal remodeling after implantation of a shape-changing inlay concurrent with myopic or hyperopic laser in situ keratomileusis Roger Steinert, MD, Douglas Koch, MD, Beatrice Cochener, MD, Alan Lang, PhD, Enrique Barragán-Garza, MD, Arturo Chayet, MD, Luis Vargas, MD When a corneal shape-changing inlay is used in conjunction with either hyperopic or myopic LASIK, how does that affect the induced add power as well as epithelial remodeling? Investigators in this retrospective case series set out to determine this. In the study, the Raindrop Near Vision Inlay (ReVision Optics, Lake Forest, California) was implanted under the flap in the nondominant eye, immediately following either hyperopic or myopic LASIK. A mean uncorrected near visual acuity of 20/25 was found, with 85% of patients in both the hyperopic and myopic groups reaching this mark or better. Likewise, in both groups 62% of patients had uncorrected distance vi- sual acuity of 20/32 or better. For both groups, the add power profiles as well as the epithelial thinning profiles were similar. Investigators concluded that regardless of whether patients underwent hyperopic or myopic LASIK treat- ment in conjunction with inlay implantation their acuity postoperatively as well as epithelial remodeling and induced add profiles were the same. Determining total corneal power after small incision lenticule extraction in myopic eyes Pinghui Wei, MD, Yan Wang, MD, PhD, Tommy C.Y. Chan, FRCS, Alex L.K. Ng, MRCS, George P.M. Cheng, FRCS, Vishal Jhanji, MD In this retrospective case series, investigators examined how different meth- ods for determining corneal power compared after small incision lenticule extraction (SMILE). They also determined if based on postoperative values they could estimate preoperative corneal power. Investigators found that be- tween theoretical postoperative K readings, calculated by the clinical history method and mean K after surgery obtained with the Pentacam HR (Ocu- lus, Arlington, Washington), there was significant correlation. The average equivalent K readings, also obtained using the Pentacam HR, and theoretical postoperative ones were not significantly different. Investigators determined that both the measured mean K and the estimated preoperative mean K de- rived by using the anterior-posterior method were comparable. Investigators concluded that for eyes that have undergone SMILE, practitioners can get a good estimate of corneal power using equivalent K readings. In addition, to predict preoperative corneal power, the anterior-posterior method may work well in these patients. Prospective multicenter study on endophthalmitis after cataract surgery: Effect of behind-the-lens washout Tetsuro Oshika, MD, Yuichi Ohashi, MD Investigators set out to determine whether incidence of postoperative en- dophthalmitis was linked to cataract surgery-related factors. Included in this prospective case series were 9,720 eyes. Of the 9,100 eyes that completed a 2-month follow up, three endophthalmitis cases developed, and these were significantly associated with OVD removal following lens implantation. Investigators found that when the behind-the-lens technique was used to ensure OVD was removed, there were no cases of endophthalmitis versus 0.084% in instances where this wasn't used. No other factors were found to correlate here. Investigators concluded that for reducing infectious endoph- thalmitis, washing OVD from the capsular bag using the behind-the-lens technique was a significant factor. November 2017 Dr. and Mrs. Chang Source: David F. Chang, MD zation of his or her choice. Dr. and Mrs. Chang hope the $50,000 grant will not only support the awardees' continuing work, but will also allow the honoree to publicly highlight a deserving charitable organization before ASCRS' vast international audience. "As the world's population ages, cataract blindness in developing countries will continue to climb," Dr. Chang said. "There are proven, cost-effective solutions that need to be scaled and many dedicated indi- viduals and organizations that merit our collective support." The inaugural award will be made at the 2018 ASCRS Annual Meeting in Washington, D.C. The nomination period is now closed, but an astounding 62 ASCRS mem- bers and humanitarian eyecare pro- fessionals made the effort to nom- inate a worthy candidate. The first awardee is currently being selected by a diverse nominating committee and the ASCRS Foundation board. The winner will be announced in the January issue of EyeWorld.
