Predicting emulsification in Silicone Oil
Researchers studied straylight in explanted silicone oil samples to predict emulsification, finding increased straylight in samples from patients with visible oil droplets and specific indications, suggesting it as an early indicator for timely silicone oil removal.

New IOL material - xPIB
Researchers have developed a novel intraocular lens (IOL) made of crosslinked polyisobutylene (xPIB), which showed promising results in terms of material quality and optical performance. The Eyedeal lens demonstrated lower glistening density and a higher contact angle compared to the AcrySof lens, a widely used control. The study suggests that xPIB could be a suitable material for IOLs, with clinical trials already underway in China and planned for Europe.

Oil and Lenses don't mix
Researchers studied how silicone oil adhesion to intraocular lenses (IOLs) affects straylight, finding significant increases in straylight. The study also showed that the cleaning solution F4H5 can reverse straylight values, but surface changes remain.

The safety of Reversible Trifocality.
The paper "Rotational Stability of Toric Capsular Bag–Fixated Intraocular Lenses in Duet Procedure for Reversible Trifocality" evaluates the long-term rotational stability of toric intraocular lenses in polypseudophakic eyes. The study found that the presence of a second lens in the sulcus did not affect the rotational stability of the first lens in the capsular bag.

Overcoming implantation challenges with SING IMT
The SING IMT is a second-generation implantable miniature telescope designed to improve visual acuity and quality of life in patients with late-stage age-related macular degeneration (AMD). It features a smaller incision and improved surgical techniques compared to its predecessor. The device has shown significant improvements in distance and near visual acuity and is considered safe and effective in short-term studies.

Enlarged incisions – but why?
Researchers analyzed 409 incisions from 13 IOL injector models to identify factors affecting final incision size in cataract surgery, finding that injector tip diameter, preoperative incision size, insertion depth, and incision length significantly impact final incision size.

Two Apple cores
Dr. David J. Apple, a renowned ophthalmologist and pathologist, founded the David J. Apple Laboratory for Ophthalmic Devices Research. He trained over 200 students and doctors, known as the "Apple Korps," and made significant contributions to cataract surgery and intraocular lens (IOL) implantation. After his death in 2011, his laboratory was transferred to the University of Heidelberg, Germany, where Dr. Gerd U. Auffarth continues his work, now known as the Auffarth-Apple Korps.

Team VitreoSub is a winner!
The provided sources discuss various topics related to the vitreous body and retinal care. The vitreous body is a gel-like substance that fills the posterior chamber of the eye, maintaining the eyeball's shape. Vitreous Retina Macula Consultants of New York (VRMNY) is involved in clinical trials for wet age-related macular degeneration and diabetic macular edema, and their doctors have spoken at conferences on multimodal imaging and ophthalmic ultrasonography. Healio provides news articles, videos, and podcasts on retinal conditions, including the use of multimodal imaging, novel VEGF inhibitors, and mitochondrial stabilizers. Vitreoretinal Consultants of NY shares updates on their practice and announces the win of the Science4Life Venture Cup 2024 by their team, VitreoSub, for developing vitreous body replacement strategies.
