Diffractive optic IOL provides good near, distance vision in all lighting conditions
April 1st 2003New Orleans-The AcrySof ReSTOR IOL (Alcon), with apodized diffractive optic technology, is providing good near vision and good distance vision under all lighting conditions, based on early results in U.S. clinical trials. In addition, the lens is producing few unwanted visual phenomena, according to Stephen Brint, MD.
Should a prostaglandin agent be used as initial monotherapy?
April 1st 2003Not long after topical timolol was introduced in 1978, it became one of the most widely prescribed glaucoma medications in the world. Although timolol is considered to be the most significant therapeutic advance in the medical treatment of glaucoma in the 20th century, the 1994 introduction of prostaglandin analogs for glaucoma treatment in Japan marked the end of timolol's domination.
Eyelid lesion management requires careful history, exam
April 1st 2003Baltimore-Ophthalmologists can be comfortable identifying and managing certain eyelid lesions in their offices if they pay attention to a few basic principles. A working knowledge of common benign and malignant lesions is the key to managing these lesions, according to Shannath L. Merbs, MD, PhD, who spoke at the Current Concepts in Ophthalmology meeting here.
OHTS identifies thinner corneas as risk for visual changes
April 1st 2003Omaha, NE-The Ocular Hypertension Treatment Study (OHTS) clearly demonstrat-ed that topical IOP-lowering medications can delay the onset of primary open-angle glaucoma. In addition, the OHTS study also revealed two very important secondary messages, which may be as important as the primary finding, according to M. Roy Wilson, MD.
Wavefront-guided refractive surgery: promise and pitfalls
April 1st 2003Refractive surgery in the next few years will be dominated by the intellectually and, we hope, clinically exciting introduction of wavefront-guided surgery. Both from the viewpoint of improving our current results and for the treatment of the patient suffering adverse optical sequelae after LASIK, wavefront technology offers a novel and promising diagnostic and surgical approach. Indeed, refractive surgery today-borrowing from optics, astronomy, physics, engineering, and biology-represents the ultimate fusion of science, technology, and medicine.
Lamellar corneal procedure useful for reparative surgery
April 1st 2003Jacksonville, FL-Mastering the lamellar corneal surgery technique may extend the benefits to both physician and patient well beyond LASIK, according to Arun C. Gulani, MD. In the technically demanding surgery, a partial-thickness cornea is replaced with donor tissue of the same size and thickness.
Technology mitigates distance when doctors travel
April 1st 2003Do you remember not long ago that a trip overseas meant virtually losing contact with home? Even a simple task such as making a phone call became an adventure- looking for the correct change with foreign coins, placing them in the appropriate slots, and then, of course, figuring out the time back home.
Birdshot chorioretinopathy presents diagnostic challenge
April 1st 2003Editors Note: Birdshot chorioretinopathy (BSCR) is an uncommon, but potentially serious, inflammatory disorder that involves both the choroid and retina. No systemic associations have been observed consistently to date. While a strong association with the HLA-A29 class I antigen suggests a genetic predisposition, the vast majority of HLA-A29-positive patients never develop BSCR, and the trigger in that small proportion of HLA-A29-positive patients that does develop the disease is unknown.
Advances in myectomy surgery give better cosmetic results
April 1st 2003Editor's Note: I developed myectomy surgery more than 25 years ago, and this procedure has been confirmed to be the best surgical treatment for blepharospasm. I have performed more than 1,000 myectomy procedures, and while functional results (reduction in spasm) have not changed greatly in the past few years, cosmetic results have improved greatly and negative side effects and healing time have been reduced.
Technology in trials: Early results promising for presbyopia reversal
April 1st 2003Orlando-Early results from a clinical trial for the reversal and treatment of presbyopia, using SurgiLight Inc.'s OptiVision technology, appear "promising," according to researchers at New York-Presbyterian Hospital Weill Cornell Medical Center.
Therapy for retinal arterial macroaneurysms still an open question after 30 years
March 15th 2003This report provides a brief review of macroaneurysms, reviews two recently described applications of investigational tools that may assist in diagnosing a macroaneurysm when it is obscured by hemorrhage, reviews two approaches for the management of subhyaloid hemorrhage arising from a macroaneurysm, and discusses a rationale for the application of photocoagulation when treating selected macroaneurysms.
Bimanual technique easily learned for micro-phaco
March 15th 2003Kansas City, MO-Making the transition from a standard phacoemulsification technique to a bimanual technique requires cataract surgeons learn to perform phaco through two micro-incisions and to develop their skills using an irrigating chopper.
Computerized integrated system must meet practice needs
March 15th 2003Orlando-When considering computer office integration, physicians must consider what is essential versus what may be little more than a luxury to a smooth-running office. It may or may not be economically feasible to tie all aspects of a practice into a readily accessible communication network at this point.
Accommodative response measures vary with different tests
March 15th 2003Orlando-The accommodative response in pseudophakic patients with an accommodative posterior chamber IOL (Human Optics, Erlangen, Germany) implanted is difficult to interpret when measured by various clinical tests, and the pseudophakic accommodation should be differentiated from pseudoaccommodation, according to Achim Langenbucher, PhD.
Bimanual microphacoemulsification: the next phase?
March 15th 2003Cataract removal by means of phacoemulsification has improved over the last 35 years in small, incremental steps. The sequential introductions of capsulorhexis, foldable IOLs, clear corneal incisions, and topical anesthesia have made small improvements in the safety andefficacy of cataract surgery and as a whole have taken us one giant leap forward.Bimanual phacoemulsification is just another one of these small steps that may ultimately enhance our ability to offer the best surgical procedure to our patients.
Research aims to boost preservation of retinal cells
March 15th 2003Baltimore-Researchers are working to improve their understanding of the cascade of events that lead to retinal degeneration and vision loss. This active research could lead eventually to clinical treatments, according to Jennifer Sung, MD, who spoke at the Current Concepts in Ophthalmology Meeting here.
Lessons from ONTT help in management of optic neuritis
March 15th 2003Baltimore-Ophthalmologists can now use new guidelines on how best to treat optic neuritis based on the results from the Optic Neuritis Treatment Trial (ONTT), which followed long-term outcomes for 10 years, according to Neil R. Miller, MD, who spoke at the Current Concepts in Ophthalmology Meeting.
