San Francisco-LASIK surgeons seeking to create thin flaps in order to maximize ablation depth while maintaining a 250-?m stromal bed would be prudent to set 120 to 130 ?m as their lower limit for intended flap thickness, said Lee T. Nordan, MD, at the American Society for Cataract and Refractive Surgery annual meeting.

Monrovia, CA-STAAR Surgical has introduced an environmentally controlled cartridge for its injector systems that appears to maintain high lubricity and improve performance during IOL implantation, accord-ing to several physiciansfamiliar with the new system.

The Kawai Capsulorrhexis Forceps (model AE-4388, ASICO) are designed for use in difficult cases of continuous curvilinear capsulorhexis (CCC), according to their creator, Kenji Kawai, MD.

The pupil that dilates poorly is frequently associated with both glaucoma and complications during combined surgery. With newer endolenticular techniques, especially with nucleofractis procedures and chop techniques, pupils do not need to be as large as previously required.1-4 However, there still are numerous instances in which the pupil is inadequate to allow the surgeon to proceed, and some form of manipulation or surgery is required.

Atlanta-When performing aphakic IOL calculations in eyes that have undergone corneal refractive surgery, contact lens over-refraction is the single best method for determining the value of corneal power (K). When preoperative K is known, averaging values obtained from both contact lens over-refraction and the keratometric history technique yields even better results. Nevertheless, both techniques remain suboptimal, yielding highly variable results, according to George O. Waring III, MD.

When Bruce Koffler, MD, brought optical dispensing into his practice, he was not convinced completely that it was a good idea. That was 3 years ago. Now, he wishes he had done it sooner.

San Francisco-Corneal topography and wavefront data are key to assessing the internal aberrations of the eye accurately and are essential for surgeons to perform customized ablations accurately, said Stephen D. Klyce, PhD, who spoke during the Innovator's Session at the American Society of Cataract and Refractive Surgery annual meeting.

San Francisco-Refractive surgery continues to evolve as researchers strive to achieve better quality of vision for patients, said Ioannis G. Pallikaris, MD, PhD, the first ophthalmologist to deliver the Charles D. Kelman Innovator's Lecture at the American Society of Cataract and Refractive Surgery annual meeting.

Editor's Note: What has 100 years of history done for ophthalmic knowledge? In many areas-cataract surgery for example-a revolution has occurred and great strides have been made. In others, surprisingly, very little has advanced.

Rochester, NY-Bausch & Lomb will delay the regulatory filing for the intravitreal fluocinolone acetonide implant (Retisert), a treatment for diabetic macular edema (DME), for up to 3 years while the FDA reviews 12-month safety data of additional eyes treated with implants.

San Francisco-The BD K-4000 microkeratome (Becton, Dickinson & Co.) can be used reliably to create high-quality flaps of predictable dimensions, said Robert M. Kersh-ner, MD, at the American Society of Cataract and Refractive Surgery annual meeting.

Fort Lauderdale, FL-Novartis Ophthalmics and QLT Inc. have received the 2003 Helen Keller Prize for Innovation in Eye Care for their development of verteporfin for injection (Visudyne) therapy.

Somerset, NJ-MedPointe Inc. has acquired all U.S. and Canadian rights to azelastine HCl (Optivar), a treatment for itching of the eye associated with allergic conjunctivitis in adults and children ages 3 and older.

STAAR Surgical has submitted the final module of its FDA pre-market approval papers for its implantable contact lens (ICL).

Dublin, CA-Carl Zeiss Meditec Inc. has purchased worldwide distribution rights to a new perimetry device for the detection and management of age-related macular degeneration (AMD).

A loading forceps (American Surgical Instruments Corp. [ASICO]) is designed to set an IOL in the cartridge easilyand rapidly and without damaging the lens surface. The device, the Akahoshi Acrylic Loading Forceps AE-4253, was designed by Takayuki Akahoshi, MD, director of the Mitsui Memorial Hospital in Tokyo, Japan.

Heidelberg, Germany-The accommodative power of a new accommodative IOL is about 1 D compared with that of a monofocal IOL that provided pseudoaccommodation of about 0.5 D, according to Gangolf Sauder, MD, and Jost Jonas, MD.

Dayton, OH-Move over a few disc diameters from the optic nerve head to assess the retinal thickness in the para-macular region for early diagnosis and close monitoring of the glaucomatous process. That's the message of Talia Technology Inc., Tampa.

Durham, NC-Corneal thickness should be taken into account when assessing a patient's risk profile for progression from ocular hypertension to glaucoma, according to a Duke University glaucoma specialist.

Milwaukee-The approach to repairing a bleb leak in the office needs to be in the context of what will provide the greatest benefit for the patient with the least amount of risk, according to glaucoma specialist Dale K. Heuer, MD.

When prescribing ophthalmic drugs, the decision of whether to opt for a generic substitute involves greater consideration than may be required for a systemic agent.

San Francisco-Mounting evidence supports a relationship between the immune system and glaucoma, according to Martin B. Wax, MD, a cell biologist and ophthalmologist.

Saratoga, CA-A pivotal trial has begun with the implantable miniature telescope (IMT) (VisionCare Ophthalmic Technologies Inc., Saratoga, CA), a low vision IOL for patients with age-related macular degeneration (AMD), following a successful phase I trial. In that trial, most patients gained three or more lines of near or distance visual acuity and improved their ability to perform daily activities.

Fort Lauderdale, FL-Central corneal thickness (CCT) influences IOP measurement and almost certainly plays an important role in pharmacokinetics. However, a recent study found that CCT did not significantly affect mean IOP despite differences in CCT between black and non-black patients who had been treated for open-angle glaucoma (OAG) or ocular hypertension (OHT).

San Francisco-Due to the rapid aging of the U.S. population, public health officials are predicting a dramatic increase in the prevalence of open-angle glaucoma (OAG) over the next 2 decades.

The FDA has approved the expansion of the clinical trial of Anamed Inc.'s Perma-Vision intracorneal lens for the correction of hyperopia up to +6 D.

The FDA will allow an increase in the number of clinical trial patients eligible to be treated for presbyopia with SurgiLight's OptiVision system.
