Can an intracameral mydriatic combination reduce need for pupil expanders?Intracameral administration of the fixed combination of phenylephrine and ketorolac injection 1%/0.3% (Omidria, Omeros) during cataract surgery is safe and effective for maintaining pupil dilation, and minimizes the need for a pupil expansion device, according to the findings of a retrospective study conducted by Frank A. Bucci, Jr., MD.
Clinical experience with a mechanical pupil dilatorCataract patients with small pupils present a particular challenge for surgeons. Using a pupil expansion device such as the Malyugin ring may help to reduce the complications associated with small pupil cataract surgery.
The proper procedure for testing pupilsBecause of its potential to reveal serious retinal, neurologic or other disease, pupil testing is a crucial part of the ophthalmic examination and requires astute observation. This procedure should be included as a component of every comprehensive examination or any time a patient needs to be dilated—in addition to any problem-focused visit involving eye health, such as a red eye visit, ocular emergency, or intraocular pressure (IOP) check.
Wearable device aids early detection of diabetic autonomic neuropathyResearchers at National Taiwan University Hospital have developed a wearable optical device that can detect sluggish pupil reaction, a symptom of diabetic autonomic neuropathy.
Effects of astigmatism greater on multifocals than monofocals IOLsThe effect of astigmatism varies with different factors and can affect patient satisfaction with multifocal or monofocal IOLs.
