New-generation presbyopia-correcting IOLThe U.S. IDE clinical trial of the investigational extended range of vision IOL (Model ZXR00; Tecnis Symfony Extended Range of Vision IOL, Abbott Medical Optics) found that the implant delivered a full range of uncorrected vision and minimized or eliminated the need for spectacle wear in most patients.
Treating presbyopia with an eye drop?A topical treatment that breaks apart disulfide bonds between crystalline lens proteins was shown to increase accommodative amplitude and improve near visual acuity in a randomized, placebo-controlled clinical trial.
Technique targets source of rainbow glare symptoms
Technique targets source of rainbow glare symptomsRainbow glare rarely occurs after femto-LASIK surgery and is usually transient. Phototherapeutic keratectomy of the flap undersurface targets the cause of the glare and has been used to immediately resolve symptoms in patients with persistent disabling rainbow glare.
What a novel scleral implant may mean for presbyopia
What a novel scleral implant may mean for presbyopiaA scleral implant surgery system for presbyopia is being evaluated in a phase III study. One investigator talks about his experience.
Keratoconus as refractive surgery: Thinking outside the ‘cone’
Keratoconus as refractive surgery: Thinking outside the ‘cone’In this first of a two-part series, Arun C. Gulani, MD, MS, explains how approaching keratoconus as a refractive surgery will change the way both ophthalmologists and patients will approach this condition to bring in a new era of not only relieving but also enhancing the lifestyle of this patient population. In Part 2, Dr. Gulani will share strategies and cases of patients with keratoconus with different case scenarios in action.
How endothelial cell loss in DSEK compares to PKAt the 10-year time point after Descemet stripping endothelial keratoplasty, the endothelial cell density is comparable to that after penetrating keratoplasty at the same time.
Selective two-photon collagen crosslinking: Why more is better
Selective two-photon collagen crosslinking: Why more is betterSelective two-photon collagen crosslinking has been shown to stiffen any three-dimensional region inside corneal tissue without damaging surrounding tissues.
Which is superior: LASIK or contact lenses?Steven Dell, MD, and Steve Schallhorn, MD, compared the visual and subjective outcomes in patients who wear contact lenses with those who underwent wavefront-guided LASIK for the correction of myopia and astigmatism.
Determining best cases for IOL implantation in childrenWhen the topic of IOL implantation is on the table, the age of the patient does make a difference, according to pediatric expert Courtney Kraus, MD, who spoke at the Wilmer Eye Institute’s 27th annual Current Concepts in Ophthalmology conference.
Finding the ideal mix-and-match IOL strategyTwo clinicians explore why an optimal visual solution for patients may be using both a low-add multifocal and an extended-range-of-vision lens.
