White light is comprised of different wavelengths of visible light, ranging from red (700 nm) to violet (400 nm). As white light passes through an optical system, each of its component wavelengths bends independently.
My interest in refractive surgery started in 1976 when my good friend and fellow University of Southern California (USC) ophthalmology resident Rick Villaseñor returned from his course in keratomileusis surgery with Jose Barraquer in Bogota, Columbia.
Fluorescence of lens proteins could help understand, diagnose, and treat cataracts, researchers say.
“Rather than waiting for the condition to appear, it could be possible to diagnose and monitor cataract before it forms, allowing preventative measures to be taken where possible,” said Rory Duncan of Heriot-Watt University in Edinburh, United Kingdom in a press release.
America may face a public health crisis in coming years unless drastic changes are not made to the public perception of eye health, according to a report from the National Academies of Sciences, Engineering, and Medicine (NASEM). Taking steps to create a public conversation about the matter, Allergan has launched a public awareness campaign, See America, to improve this awareness of and access to comprehensive eye exams.
Phenylephrine 1%/ketorolac injection 0.3% added to ophthalmic irrigation solution and administered intracamerally during cataract surgery was associated with a statistically significant reduction in surgical time, intraoperative complications, and use of pupil dilating devices and with a statistically significant improvement in best-corrected visual acuity.
An intraoperative injection of a compounded formulation of triamcinolone acetonide, moxifloxacin, and vancomycin eliminated the need for supplemental postoperative medications in the vast majority of patients who underwent phacoemulsification and IOL implantation.
