Phakic IOL maintains benefits of PMMA version
March 1st 2006Chicago—The foldable version of the iris claw fixated myopic phakic IOL (Artiflex II/Veriflex, Ophtec/AMO) affords faster recovery of excellent uncorrected visual acuity (UCVA) compared with the polymethylmethacrylate (PMMA) model (Artisan/Verisyse, Ophtec, AMO), but otherwise has the same favorable efficacy and safety profile associated with its widely used predecessor, according to results of a prospective, intrapatient comparison study reported by Jose L. Guell, MD, PhD, at the subspecialty day meeting sponsored by the International Society of Refractive Surgery of the American Academy of Ophthalmology.
Phakic IOL good for corrrecting high myopia

Surgical approaches to presbyopia undergoing evolution
March 1st 2006Lisbon, Portugal—If presbyopia is the "final frontier" in refractive surgery, which surgical approach will stand out as the winner in treating patients with the condition? Will it be corneal surgery, intraocular surgery, or phakic-versus-pseudophakic approaches? Samuel Masket, MD, asked at the European Society of Cataract and Refractive Surgeons (ESCRS).
Current strategies effectively reduce PCO occurance
March 1st 2006Baltimore—Extensive research has already led to the identification of a number of surgery- and IOL-related factors that can be targeted to reduce the occurrence of posterior capsule opacification (PCO). Investigators are continuing to evaluate new strategies to reduce its risk further in the future, said Albert S. Jun, MD, PhD, at Current Concepts in Ophthalmology, Baltimore.
Foldable lens receives NTIOL status for significant reduction in spherical aberration
March 1st 2006Advanced Medical Optics (AMO) Inc.'s Tecnis foldable IOL has earned the title of New Technology IOL (NTIOL) from the Centers for Medicare and Medicaid Services (CMS). The designation follows labeling claims approved by the FDA in April 2004 that the lens reduced postoperative spherical aberrations compared with lenses with spherical optics and improved night driving simulator performance. The designation was effective Feb. 27.
New understanding of AMD leads to earlier interventions
March 1st 2006The recently reported success with vascular endothelial growth factor (VEGF) inhibitors in patients with age-related macular degeneration (AMD) provides an important new therapeutic modality for wet AMD and an exciting victory for biotechnology. Yet, the best results will eventually come from interventions that target earlier steps in AMD pathogenesis.
New instrumentation offers advance for IOP measurement
March 1st 2006Lisbon, Portugal—Newer tonometry technology seems to offer an improvement over Goldmann tonometry for more accurate IOP measurement in post-LASIK eyes, explained Jay Pepose, MD, PhD, at the XXIII Congress of the European Society of Cataract and Refractive Surgeons.
Gifts to create major genetics test lab at UI
March 1st 2006Iowa City, IA—The University of Iowa's (UI) Center for Macular Degeneration (CMD) will be able to advance its mission with the creation of a large-scale nonprofit genetics testing laboratory, made possible by two gifts totaling $6.2 million.
FDA expands indication for bromfenac use
March 1st 2006Irvine, CA—ISTA Pharmaceuticals Inc. announced that the FDA has approved its supplemental new drug application (sNDA) for bromfenac ophthalmic solution 0.09% (Xibrom). The indication expands bromfenac's indication to include the treatment of pain following cataract surgery.
Endophthalmitis incidence holds steady in United Kingdom
March 1st 2006Chicago?Results of a study evaluating post-cataract surgery endophthalmitis at a regional tertiary referral center in England show no evidence for an increase in incidence over a recent period of almost 8 years, reported Omar M. Durrani, FRCS, at the annual meeting of the American Academy of Ophthalmology.
Pay for performance likely to become physicians' reality
March 1st 2006Chicago?Pay for performance (P4P) is going to be a reality in the very near future, according to William L. Rich III, MD, who explained the whys and wherefores of this complex topic during the retina subspecialty day at the American Academy of Ophthalmology annual meeting.
Debate continues over presbyopic lens exchange
March 1st 2006Chicago-The future of presbyopic lens exchange for high myopia looks bright with the development of various IOL options, according to one proponent. Yet, surgeons and patients should be aware of possible complications, such as retinal detachment, and seek alternatives, cautions another refractive surgeon.
SPR study shows value of scleral buckling surgery
February 23rd 2006Retinal surgeons need to retain skill in performing scleral buckling because that procedure has a benefit compared with primary vitrectomy for the management of complex retinal detachment in phakic patients, said Michael H. Foerster, MD, at the World Ophthalmology Congress.

February 23rd 2006Proper management of cataract cases involving intraoperative floppy iris syndrome (IFIS) should keep surgeons from experiencing complications associated with the problem, reported Alan Crandall, MD, at the World Ophthalmology Congress on Thursday.
Meticulous intravitreal injection technique essential for minimizing endophthalmitis risk

Intravitreal triamcinolone widely used, but evidence base is lacking
February 23rd 2006Use of intravitreal triamcinolone acetonide has quickly gained favor among retinal specialists as a first-line treatment for treatment of macular edema associated with retinal vein occlusion (RVO). However, findings from an evidence-based literature review indicate published data to support what has become a widespread clinical phenomenon are broad but not deep, said Robert Bhisitkul, MD, PhD, at the World Ophthalmology Congress."The purpose of this analysis was to look beyond the clinical impression that this therapy results in improved vision and reduced macular thickness by considering its long- versus short-term clinical effects. Its results show our best available evidence is inconclusive at best, but results of ongoing studies should give us a greater level of confidence in using intravitreal triamcinolone to treat patients with RVO," said Dr. Bhisitkul, professor of clinical ophthalmology, University of California San Francisco, in the United States.
