Article originally published on Healio, Nov. 16, 2021. Figure 1a. Precut and prestained CAIRS immediately after preparation in an eye bank setting. Figure 1b. The donor material is shipped in storage solution, rinsed with saline and then implanted. Corneal allogenic intrastromal ring segments have been described by Jacob and colleagues for the treatment of […]
Article originally published on Healio, July 9, 2021. Pinhole pupilloplasty has helped change many lives. The idea of small-aperture optics is not only simple but advantageous in cases of high astigmatism. Jack S. Parker, MD, PhD, of Parker Cornea and the Netherlands Institute for Innovative Ocular Surgery (NIIOS), is my guest columnist this month, and […]
From Healios June 18, 2021 AMELIA ISLAND, Fla. — In this video from Cataract Surgery: Telling It Like It Is, Jack S. Parker, MD, PhD, discusses the importance and difficulty of knowing what to say to patients following cataract surgery that does not go as planned. Watch the video
From Healios June 18, 2021 Recently, Descemet’s membrane endothelial keratoplasty has emerged as the preferred treatment for corneal endothelial dysfunction because it affords the best visual acuity with the lowest risk for various complications. As the operation has grown more popular, various innovations to the technique have been introduced, including so-called “patient ready” DMEK, featuring […]
Article originally published on Healio, Nov. 16, 2021. Office-based surgery exploded into the popular consciousness with the publication of the 2015 Kaiser study, reporting more than 21,000 cataract operations performed safely and effectively in clinic minor procedure rooms. Since then, office-based surgery (OBS) suites have trickled into existence throughout the United States. These have primarily […]
S- or F-stamping donor tissue for Descemet’s membrane endothelial keratoplasty is widely practiced to guard against DMEK’s most embarrassing potential complication: accidental upside-down graft implantation. These orientation marks are so common, in fact, that many DMEK surgeons have never even attempted the operation without them. However, the originally described DMEK technique was stamp-free, and that […]
When starting with Descemet’s membrane endothelial keratoplasty, it is common to manually mark a ring of purple dots on the corneal surface to serve as a centering guide for the graft’s final position. Although technically easy to apply, this array of purple dots may entail two notable drawbacks. First, inking the corneal surface is a […]
Ultrasert is the name of Alcon’s delivery system for its preloaded AcrySof IQ IOLs. These lenses arrive already packaged inside their injector and need only priming with viscoelastic before delivery. Still, the process is not entirely foolproof, and some amount of technical skill is nevertheless required. One common problem is failure of the leading haptic […]
