Article Synopsis
  • The study evaluated the long-term outcomes of scleral fixation of aniridic black diaphragm intraocular lenses (BDIOL) in 38 eyes affected by aniridia and aphakia due to trauma or congenital conditions.
  • After an average follow-up of 28 months, there was a significant improvement in visual acuity, and patients reported reduced glare and photophobia, though some experienced complications like elevated intraocular pressure and corneal decompensation.
  • The findings suggest that scleral fixation of BDIOL is an effective solution for patients lacking capsular support, providing good vision quality with a low rate of complications, regardless of prior surgical history.

Intraocular lens (IOL) dislocation is not an uncommon complication and often requires surgical intervention, depending on the status of capsular bag support. Conventionally, posterior dislocation of a foldable IOL or the IOL-bag complex warrants their removal as foldable IOLs are not ideal for sulcus placement. The technique presented here describes using quadrilateral sutures to refix looped haptic IOLs at the ciliary sulcus with or without a bag complex.

Peptide-enabled ribonucleoprotein delivery for CRISPR engineering (PERC) is a new approach for ex vivo genome editing of primary human cells. PERC uses a single amphiphilic peptide reagent to mediate intracellular delivery of the same pre-formed CRISPR ribonucleoprotein enzymes that are broadly used in research and therapeutics, resulting in high-efficiency editing of stimulated immune cells and cultured hematopoietic stem and progenitor cells (HSPCs). PERC facilitates nuclease-mediated gene knockout, precise transgene knock-in, and base editing.

This report describes a case of a patient with active multiple myeloma who was started on bortezomib, cyclophosphamide and dexamethasone and subsequently presented to the emergency department with acute intestinal obstruction one week later. The patient underwent exploratory laparotomy, but no mechanical cause of the obstruction was found. The patient later developed sepsis and eventually died.

Purpose: To analyze the outcomes following conventional internal limiting membrane (ILM) peeling versus perfluoro octane-assisted inverted flap technique for large macular holes (MH).

Methods: A consecutive 99 eyes of 99 patients were enrolled {45 - conventional group and 54 - inverted flap (InFlap) group}. The primary outcome was a difference in closure rate.
