New accommodating lens takes advantage of ciliary muscle power for presbyopic patients
September 15th 2006San Francisco-The quest for relief of visual dysfunction for presbyopic patients continues with the design of a new accommodating lens-the OPAL posterior chamber accommodating IOL (Bausch & Lomb).
Initial experience good with accommodating IOL
September 15th 2006San Francisco-In an initial analysis, the Synchrony dual-optic single-piece IOL (Visiogen) performed well. The visual results were good, there were no major complications and no glare or halos after implantation, and patient satisfaction was high, according to George Beiko, BM, BCh, FRCS.
Accommodative lens results considered 'disappointing'
September 15th 2006San Francisco-In a study that quantified the anterior movement of an accommodative IOL (HumanOptics 1CU lens), the investigators reported an anterior shift of less than 0.5 D of accommodation, which was disappointing in that patients were not spectacle-independent, according to Eduardo Marques, MD, who spoke here at the American Society of Cataract and Refractive Surgery annual meeting.
AART focus is on prevention of sight-threatening CNV
September 15th 2006The Anecortave Acetate Risk Reduction Trial (AART) recently completed enrollment of 2,596 patients worldwide. The study is being conducted in the United States, Europe, Australia, and South America. Sites have also been added in India and Singapore under a different protocol number. AART is investigating the ability of anecortave acetate 15 mg or 30 mg to prevent sight-threatening choroidal neovascularization (CNV) in high-risk eyes when compared with a sham procedure.
Remote imaging system increases doctor's reach to premature infants
September 15th 2006Palo Alto, CA-Darius Moshfeghi, MD, pediatric retina specialist at Lucile Packard Children's Hospital, Palo Alto, CA, and one of just a few physicians in California's Bay Area trained to diagnose retinopathy of prematurity (ROP), is using technology to bring his expertise to premature babies without having to travel to see them.
Aspheric IOL helps reduce higher-order aberrations
September 15th 2006San Francisco-Both the SA60AT (AcrySof, Alcon Laboratories) and the SN60WF (AcrySof IQ, Alcon) IOLs are associated with excellent visual acuity outcomes after cataract surgery. However, with its aspheric optic, the SN60WF significantly reduces higher-order aberrations (HOAs) and results in greater improvement in contrast sensitivity as well as patient satisfaction with visual function, said Helga P. Sandoval, MD, at the annual meeting of the American Society of Cataract and Refractive Surgery.
Phakic lenses provide safe, precise refractive correction
September 15th 2006San Francisco-In the ongoing debate over the superiority of refractive procedures, phakic lenses are receiving increasing attention because they preserve and improve the quality of vision, according to Jos? L. Guell, MD, PhD.
Corneal shape guides astigmatism treatment after transplant surgery
September 15th 2006San Francisco-"The choice of corneal procedure that the surgeon will perform to correct astigmatism after corneal transplantation depends on the corneal shape," said Sheraz Daya, MD, FACS, at the American Society of Cataract and Refractive Surgery annual meeting.
Data show ROP benefits from early therapy
September 15th 2006San Francisco-Early treatment at high-risk threshold reduces the rate of unfavorable acuity and structural outcomes in infants with retinopathy of prematurity (ROP), according to William V. Good, MD. Reporting new findings from the Early Treatment for Retinopathy of Prematurity Study (ETROP), Dr. Good added that systemic side effects are more common with earlier treatment but can be managed in the nursery.
Mandatory vision screening of kids should become reality
September 15th 2006Baltimore-The political realities of implementing mandatory vision-screening programs offer hard lessons for the dedicated individuals involved in the process. Small victories have been scored, but enormous efforts still need to be made to meet the goal of vision screening for all pre-kindergarten children with follow-up care for those identified as needing it, according to Mary Louise Collins, MD.
Children's reading problems can be complicated to decipher
September 15th 2006La Jolla, CA-Screening for problems that affect school performance can be a challenge, according to David B. Granet, MD, who posed the question: "Who evaluates whether patients understand what they see?" Dr. Granet explained the task of pediatric ophthalmologists.
Alcon, AMO settle pending patent litigation
September 15th 2006Wilmington, DE-Alcon Laboratories paid Advanced Medical Optics Inc. (AMO) $121 million as part of a global settlement agreement that resolves four patent lawsuits between the companies. The companies also agreed to work together in the future to resolve patent issues relating to new technology before heading to court.
Options for surgical management of IFIS are multiple
September 15th 2006Several options are available to cataract surgeons to manage anticipated IFIS. In the multicenter prospective trial, surgeons could use a mechanical restraining device (iris expansion ring or iris retractors) to enlarge the pupil and keep the iris from prolapsing, viscodilation with Healon 5 (Advanced Medical Optics), or pharmacologic intervention with atropine administered three times daily beginning 2 days before surgery.
Ophthalmology, urology societies unite to raise IFIS awareness
September 15th 2006The American Society of Cataract and Refractive Surgery (ASCRS), the American Academy of Ophthalmology (AAO), and the American Urological Association (AUA) have joined forces to launch a patient and prescriber education campaign about the risk of intraoperative floppy iris syndrome (IFIS) associated with the current or previous use of an alpha-1 blocker and the likelihood of successful surgery if the ophthalmologist is aware of that medication history and is able to employ appropriate surgical strategies.
Should IOP be adjusted for corneal thickness alone?
September 15th 2006While the Goldmann applanation tonometer is a very accurate instrument for measuring IOP compared with previous instruments, ophthalmologists now know that central corneal thickness (CCT) is much more variable than was believed when the instrument was developed.
CDC study confirms Fusarium link to contact lens solution
September 15th 2006A new study confirms preliminary findings that a unique outbreak of Fusarium keratitis this past spring was associated with use of ReNu with MoistureLoc (Bausch & Lomb) contact lens cleaning solution and common suboptimal hygiene practices (JAMA 2006;296:953-963).
MICS has made very little impact on US and EU surgeon practice
September 12th 2006Microincision cataract surgery (MICS), hailed to be the next big development in cataract surgery, has not had the expected impact on surgeon's practice, David Leaming revealed, whilst detailing the results of his most recent survey on cataract surgery practice in Europe and the US.

ECOS proving to be a useful tool for cataract surgeons in Europe
September 12th 2006The use of foldable intraocular lenses (IOLs) in cataract surgery is a trend that is continuing to rise across Europe, according to Mats Lundstrom speaking at the Outcomes of Cataract and Refractive Surgery symposium.
