| | Severity determines intraoperative floppy iris syndrome management approach
| Options include use of OVD, intracameral drugs, iris retractors, pupil expansion device
| | Ophthalmology Times | A cataract surgeon who first identified intraoperative floppy iris syndrome (IFIS) and its association with tamsulosin describes several approaches to managing the surgical complication. The approach a surgeon uses will depend on the severity of IFIS, he says. |
| | Newer one-piece IOL offers excellent visual acuity, says surgeon
| Lens also provides accurate refractive predictability, according to outcomes of study
| | Ophthalmology Times | | The state-of-the-art material and design of a novel one-piece IOL can offer refractive stability and predictability, according to Daniel A. Black, MBBS, FRACO, FRACS. This newer IOL rivals other more established IOLs and may soon become the gold-standard treatment in cataract procedures, he said. |
| | Advances in cataract surgery bring new complications along with benefits
| Awareness of potential plusses and minuses enables surgeons to maximize good outcomes
| | Ophthalmology Times | | Cataract surgical techniques and IOLs have both been evolving for many years. The advances have been—and continue to be—tremendous, but each new advance also has the potential to give birth to new complications. The need to suture clear corneal incisions to prevent potentially blinding complications during subsequent surgery, and the dislocation of one-piece IOLs and capsular tension rings, are examples of complications of which practitioners need to be aware. |
| | Phaco machine settings may not match delivery
| Comparative study finds flow, vacuum, surge may vary from intended values
| | Ophthalmology Times | | In a fluidics test of three phacoemulsification machines, differences were found in vacuum, flow, and postocclusion surge—and these differences were found not only between the three machines but also between the machines' own settings and what they were actually delivering. Other important findings: there is a significant amount of unoccluded vacuum at the tip, and the parameters for what constitutes a safe postocclusion surge can be dramatically different among eyes. |

| UV rays don't just damage skin
| | Ophthalmology Times | | Prevent Blindness has dedicated May as UV Awareness Month in an effort to educate the public on the best way to protect their eyes. |
| | IOL technology focuses on implant orientation, rotation
| | Ophthalmology Times | | A retrospective study of eyes with a spherical IOL implanted found the lens haptics maintained a stable position in most eyes, but significant rotation was observed in a small proportion. This information is important to consider when implanting toric IOLs where orientation and rotation can affect vision outcomes. |
| | Important eye health issues examined in Ophthalmology journal
| | Ophthalmology Times | Three studies on eye health examine the role of antioxidant supplements, the relationship of visual acuity and mortality, and the causes of glaucoma in the May 2008 issue of Ophthalmology, the journal of the American Academy of Ophthalmology.

| | How to conquer your first solo phaco
| | Ophthalmology Times | | In every phacoemulsification procedure, the critical factors remain the common goals: the care and respect bestowed on the patient and the commitment to obtaining the best possible outcome. There is no place for cynical, business-as-usual attitudes (which are found in some operating rooms) in today's environment of refractive cataract surgery and presbyopia-correcting IOL implants. An expert offers 10 steps to help post-residency ophthalmologists conquer their first solo phacoemulsification procedures. |
| | Protein adhesion studies aim to explain PCO rates
| | Ophthalmology Times | Oulu, Finland-Adhesion of soluble fibronectin differs significantly between IOLs of different materials, and that variability may explain differences between IOLs in rates of posterior capsule opacification (PCO), according to Reijo Linnola, MD. |
