MAY 16, 2020| EYEWORLD DAILY NEWS | 17 DAILY NEWS ASCRS VIRTUAL ANNUAL MEETING Poster preview I n addition to the live- streamed content at the ASCRS Virtual Annual Meet- ing, hundreds of electronic posters will also be available for viewing on demand. These posters cover a variety of topics across ophthalmic specialties. Below is a small selection of highlights of those that can be viewed more in depth through the meeting website. Patient Outcomes for Simultaneous Bilateral Intraocular Lens Surgery Jan Venter, MD, and Stephen Hannan, OD, sought to eval- uate the safety and efficacy of simultaneous approaches to pa- tients who underwent bilateral intraocular lens surgery with multifocal implants. A cohort of patients who underwent simultaneous bi- lateral (same day) intraocular lens surgery procedures with multifocal implants was com- pared to a matched cohort who underwent delayed sequential (non-simultaneous, separate day) implantations with multi- focal implants. The total number of si- multaneous procedures was 2,890 (1,445 patients), and these were compared with 6,238 (3,119 patients) non-si- multaneous procedures. Three months postoperatively, 88.0% of the simultaneous group had binocular UCDVA of 6/6 or better vs. 87.7% in the non-simultaneous group (p>0.05); 86.2% had binocu- lar UCNVA of N6 or better vs. 88.5% in the non-simultane- ous group (p<0.05). Change in BCDVA of >2 lines were measured at 3 months as 0.7% of the simultaneous group and 0.5% (p>0.05) of the non-simultaneous group. Com- plication rates between both groups were matched. Outcomes of iStent Implantation with Femtosecond Laser- Assisted Cataract Surgery Vs. Manual Cataract Surgery Beau Billings, Tyler Wickas, and Joshua Kim, MD, aimed to determine if there is a difference in IOP control and medication use in patients who have had an iStent (Glaukos) implanted following femtola- ser-assisted cataract surgery (FLACS) vs. iStent implanted following manual cataract surgery (non-FLACS). Their retrospective, comparative case series assessed IOP and glaucoma medications after successful iStent placement following femtolaser-assisted vs. manual cataract surgery. Outcome measures included IOP, medications, and standard safety evaluations. The study found that iStent implanted in combination with cataract surgery, regardless of the use of femtolaser-assisted surgery, re- sulted in statistically significant IOP and medication reductions at 12 months. There was no significant difference in IOP or medications following iStent implantation with FLACS vs. non-FLACS. Clinical Outcomes and Complications of DMEK Versus DSAEK Henry Liu, MD, and several col- leagues shared a retrospective study where the short-term and long-term visual outcomes and postoperative complications after Descemet stripping auto- mated endothelial keratoplasty (DSAEK) and Descemet mem- brane endothelial keratoplasty (DMEK) were compared. This retrospective chart re- view of consecutive patients included those who underwent DMEK (374 eyes) and DSAEK (468 eyes) at a Canadian ac- ademic hospital from January 2008 to June 2019. Ultimately, no long-term difference was observed between DMEK and DSAEK in visual acuity gained. Although both techniques had similar graft failure rates in the first 3 months, DSAEK showed higher rates of graft failure in the long-term compared to DMEK. A New Amniotic Membrane for Placement during Pterygium Surgery Hye Bin Yim, MD, introduced a new amniotic membrane (AM) for placement during pterygium surgery. The poster describes that after excision of the pterygium, the research- ers measured the size of the defect with reference to the side opposite the defective area and prepared an AM with margins 1.5–2.0 mm greater than the defect size. The AM was first sutured vertically, with reference to the opposite side of the defect. Then they sutured the upper and lower horizontal axes, and positioned the eye, from the front, slight- ly away from the direction of the opposite side of the defect. The AM was cut by reference to its boundary at the limbus, and three fixation sutures were placed. The poster stressed that appropriate AM sizing is important in terms of AM transplantation; the AM is non-elastic and easily torn. The technique transplants a cor- rectly sized AM and anchors it firmly, the researchers conclud- ed. Alzheimer's Disease: Ophthalmic Manifestations in Glaucoma and Retinal Disorders John LiVecchi, MD, and Matin Khoshnevis, MD, sought to identify and summarize key re- search that bridges Alzheimer's disease (AD) with glaucoma and retinal disorders. In doing so, the role of the ophthalmol- ogist was highlighted as a vital asset in early detection of AD as well as in the management of related visual disturbances. Additionally, relevant epide- miology was discussed. They analyzed relevant articles and found that studies have shown a significant link between AD, AMD, diabetic retinop- athy, and POAG. Advances in research have bolstered the ophthalmologist's role in diagnosing and managing AD. Ophthalmologists should have a lower threshold for a glau- coma evaluation in patients with suspected dementia. In addition, ophthalmologists should be more aware of the risk of developing dementia in patients with AMD and diabetic retinopathy.
