Purpose: To evaluate subjective and objective outcomes after combined implantation of an extended depth-of-focus (EDOF) intraocular lens (IOL) and a combined technology multifocal lens (CT-IOL).
Setting: 2 clinical practices (Carolina Eyecare Physicians, Center For Sight) in the United States.
Design: Prospective, unmasked, multicenter, nonrandomized bilateral eye study.
Purpose: ChatGPT is a commonly used source of information by patients and clinicians. However, it can be prone to error and requires validation. We sought to assess the quality and accuracy of information regarding corneal transplantation and Fuchs dystrophy from 2 iterations of ChatGPT, and whether its answers improve over time.

Setting: Two clinical practices in the USA.
Design: Ambispective unmasked non-randomized clinical trial.
Article Synopsis
- The study aimed to assess a new risk stratification system for reducing surgical complications among residents and to determine if it could enable earlier cataract surgery training.
- A retrospective analysis involving 530 cataract cases was conducted, examining factors like preoperative visual acuity and complications, using statistical models to analyze relationships between risk scores and outcomes.
- Findings revealed that while higher risk scores predicted prolonged corneal edema and postoperative complications, they did not correlate with intraoperative complications, allowing for safe introduction of cataract surgery at earlier training levels.
Purpose: To describe 2 insertion techniques, outcomes, and complications of preloaded, trifolded Descemet membrane endothelial keratoplasty (DMEK) cases using the DMEK EndoGlide inserter.
Methods: This retrospective, consecutive case series analyzed the first 35 cases using the DMEK EndoGlide performed between October 2018 and October 2019 at a single center. Preloaded, trifolded DMEK tissues were delivered through a fluid-injected or pull-through technique.
Purpose: To determine the prevalence and risk factors of exposure keratopathy (EK) across different intensive care units (ICU) at Columbia University Medical Center, including the Pediatric ICU (PICU), Medical ICU (MICU), and Neurologic ICU (NICU).
Methods: In this prospective cohort study, 65 patients were examined daily during their admission in the PICU (27 patients), MICU (15 patients), and NICU (23 patients). Data on eyelid position, conjunctival and corneal changes, Bell's and blink reflexes, medications, Glasgow Coma Scale rating, and ventilation type were collected.
Association of Risk of Obstructive Sleep Apnea With Thyroid Eye Disease: Compressive Optic Neuropathy.
Ophthalmic Plast Reconstr Surg
January 2020
Purpose: To evaluate the association of risk of obstructive sleep apnea (OSA) and thyroid eye disease-compressive optic neuropathy (TED-CON).
Methods: The authors performed a retrospective observational study. All TED patients evaluated by the principal investigator over the past 5 years were screened with the snoring tired observed pressure (STOP)-Bang questionnaire to assess their risk for OSA.
Purpose: To characterize changes in densitometry after corneal crosslinking (CXL) and correlate it with visual outcomes.
Setting: Tertiary referral academic medical center, New York, New York, USA.
Design: Retrospective case series.
We report two cases of peripheral ulcerative keratitis (PUK) imaged with anterior segment optical coherence tomography (AS-OCT). The first patient had prolonged nonsteroidal anti-inflammatory drug use, while the second had inflammatory arthritis by laboratory findings without any systemic findings as well as possible concurrent tuberculosis. In both patients, AS-OCT demonstrated corneal thinning at the onset of the disease with improvement six months after initiation of intensive medical therapy.

Design: Retrospective cohort study.
Methods: Seventy eyes of 40 patients with RP were categorized as having had phacoemulsification with intraocular lens implantation vs no cataract surgery at a single tertiary-level institution.
Lumbar spine surgery can be performed using different anesthetic techniques such as general endotracheal anesthesia (GA) or spinal-based regional anesthesia (RA). Several studies have been performed comparing these two anesthetic techniques and have revealed disparate results. As such, we set out to review the relevant literature.

Therefore, there is a need for new animal models of neuromodulation.
Objective: To introduce and validate a direct current DBS (DC-DBS) model that will use the anatomic precision of intracranial electrodes, as used in DBS, to apply direct current, as used in tDCS, over primary auditory cortex (A1) and induce electroencephalographic (EEG) changes.
