UPDATE 13 In the journal Influence of the beam profile crosslinking setting on changes in corneal topography and tomography in progressive keratoconus: Preliminary results Robert Herber, MSc, Kathleen Kunert, MD, Vera Veliká, MD, Eberhard Spoerl, PhD, Lutz Pillunat, MD, Frederik Raiskup, MD In this retrospective case series of 45 eyes, investigators examined how eyes with progressive keratoconus fared with a higher peripheral intensity corneal cross- linking technique versus a standard one using a top hat profile. The 25 eyes in group 1 received a higher peripheral accelerated crosslinking based on a modified Dresden protocol of 9 mW/cm 2 for a 10-minute time period. Meanwhile, a stan- dard top hat profile was used for the 20 eyes in group 2. Investigators found that for those in group 1 after receiving the higher peripheral crosslinking treatment, maximum keratometry decreased from 54.95 D to 53.21 D. For those in group 2, using the standard top hat profile maximum K likewise dropped from 57.29 D to 56.48 D. Following this higher peripheral intensity treatment, there was a significant decrease in both flat K and steep K for those in group 1. In this group, there was a significant decrease of –17.5 micrometers for the thinnest corneal thickness. Meanwhile, neither the flat K or the steep K was significantly flattened using the top hat approach. There was also a slight thinning of the thinnest cor- neal thickness, but this was not significant. Investigators concluded that after the accelerated crosslinking with the higher peripheral intensity profile, there was a significant improvement in both the topographic and tomographic parameters. They determined that corneal flattening appeared more pronounced with the higher peripheral intensity approach than with the standard top hat profile. Safety and efficacy of black iris diaphragm intraocular lens implantation in eyes with large iris defects: Report 4 Kevin Miller, MD, Alan Kuo, MD, Michael Olson, PhD, Samuel Masket, MD When it comes to managing aphakia and large iris defects, how safe and effective is the Morcher 67B black iris diaphragm IOL (Morcher, Stuttgart, Germany)? That's what investigators in this prospective case series involving 31 eyes of 31 patients set out to determine. At the 1-year postoperative mark, investigators found that there was a seven-line median gain in Snellen corrected distance visual acuity. They also determined that there was more than a one-line decrease in acuity in four eyes and a minor intraoperative complication in one case. In addition, there were postoperative complications seen in 21 eyes, stemming from preexisting ocular comorbidities in many of the cases. There were 12 second- ary surgical interventions needed. With this black iris diaphragm IOL patients enjoyed a mean improvement in corrected distance visual acuity with glare of six Snellen lines. Likewise, on a scale from 0 to 10, there was a 4.94-point improvement in mean subjective glare symptoms and a 3.61-point betterment in night vision. Cosmesis improved by 2.23 points. The conclusion reached was that when it comes to reducing light and glare sensitivity in aphakic eyes with large iris defects, it is relatively safe and highly effective to implant the black iris diaphragm IOL. Visual results after implantation of a trifocal intraocular lens in high myopes Gernot Steinwender, MD, Luisa Schwarz, MD, Myriam Böhm, MD, Anna Slavik- Lencova, MD, Eva Hemkeppler, MSc, Mehdi Shajari, MD, Thomas Kohnen, MD The aim in this retrospective case series, involving 36 eyes of 19 patients, was to examine how highly myopic patients fared after implantation of a trifocal intraocular lens after phacoemulsification. Included in the highly myopic group were 18 eyes of 10 patients who received an AT LISA TRI 839MP or 939MP trifo- cal IOL (Carl Zeiss Meditec, Jena, Germany), with a power of 0 to 10 D. Serving as controls were 18 eyes of nine patients who received the same trifocal IOL but with a power of greater than 10 D. At the 3-month postoperative mark those in the highly myopic group had a mean uncorrected distance visual acuity of 0.06 logMAR, mean uncorrected intermediate visual acuity of 0.13 logMAR, and mean uncorrected near visual acuity of 0.12 logMAR. In the control group the mean acuity was 0.04 logMAR. Investigators concluded that while there were satisfac- tory visual and refractive outcomes in the short term with implantation of a low power trifocal IOL in highly myopic eyes, those with the higher dioptric IOL power were better.
