Results so far in a phase II clinical trial indicate that a technique to implant sheets of immature neural retinal cells and retinal pigment epithelium together can improve vision of patients with retinitis pigmentosa or age-related macular degeneration.

All too often, practices look to alternative revenue centers that involve additional risk before looking at the no-risk option of improving current operations to put increased dollars on the bottom line. Read how one retina practice, with assistance from experienced consultants, devised a strategic plan that improved current operations and contributed to a very significant increase in revenue.

A filtering device (Cruise Control, STAAR Surgical Co.) placed between the phacoemulsification handpiece and aspiration tubing increases the stability of the anterior chamber during phaco because it decreases the post-occlusion aspiration flow rate in two venturi systems (Legacy 20000, Alcon Laboratories; Millennium venturi, Bausch & Lomb).

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.

Advanced Medical Optics Inc. (AMO) launched three refractive technologies to the European market at the annual meeting of the European Society of Cataract and Refractive Surgeons in Stockholm, Sweden.

Alcon Inc. says it has no immediate plans to conduct the additional clinical study of anecortave acetate depot suspension 15 mg (Retaane) required by the FDA in an approval letter the agency recently sent to the company.

Respondents to a survey of U.S. ophthalmology residency program directors showed only 58% had one or more residents certified in laser refractive surgery in their most recent graduating class. The number of faculty members performing laser refractive surgery, the number of lecture hours on this subject, and the presence of a cornea fellow appeared to influence certification.

Limbal relaxing incisions are making a comeback in an era of high expectations for cataract surgery outcomes and increasingly sophisticated IOLs. The procedure for performing this type of incision is relatively simple and can be performed by experienced surgeons at the slit lamp in the office.

Reaping golden rewards

The low country of South Carolina, which was once built on a thriving economy based on rice crops, is now mostly resorts. Local residents Drs. Richard Schulze and his son Richard Schulze Jr. aim to maintain the legacy of rice farming which is a nearly lost tradition. The satisfaction is not one of monetary value but of seeing the historical significance of the crop where it once flourished.

On one hand, the pay-for-performance issue has large employers, insurers, and Congress contending that the delivery of substandard medical care by physicians is hurting patient care and costing the health-care system huge sums of money. On the other hand, Congress and insurers are determined to reward physicians for providing high-quality health care and at the same time penalize them for delivering lower-quality health care. Ophthalmologists must participate in the development of standards to ensure good results. Toward that end, physician groups have devised eight ophthalmology-related quality measures, which are detailed here.

Terminating the employment of a worker may be one of the most stressful parts of your job. Here's how to lessen the chances of having to perform this task-and how to minimize the discomfort for you and your employees if you do.

Temporary legislative bandages expired at the end of 2006, so the stage is set for a dramatic increase in the number of individuals who are affected by the alternative minimum tax. Here's how to determine whether you will be one of them.

Take-home message: New discoveries about the signaling pathways regulating cross-linked actin network (CLAN) formation could in the future lead to new therapeutic approaches for steroid-induced glaucoma. CLANs are found in glaucomatous trabecular meshwork cells as well as steroid-treated cell and eye organ cultures, thus the discovery of two distinct signaling pathways is a preliminary step toward targeting of specific proteins associated with steroid-inducedglaucoma.

Researchers have completed a genome scan of 128 families with primary open-angle glaucoma (POAG) and replicated loci on chromosomes 15 and 2. Nearly one-third of the families are of African-American or Ghanaian descent, a group disproportionately affected by POAG.

Transforming growth factor beta (TGF-β2) increases outflow resistance in human anterior segments. Recent analysis has identified several candidate molecules and pathways by which elevated levels of TGF-b2 may trigger changes in outflow resistance.

Achieving high patient satisfaction rates with newer multifocal IOLs requires attention to a variety of details preoperatively, intraoperatively, and postoperatively. R. Bruce Wallace, MD, and Samuel Masket, MD, review important considerations for maximizing outcomes.

Rigorous preoperative evaluation and counseling, meticulous surgery, and thorough postoperative counseling are all critical elements for optimizing outcomes with presbyopia-correcting lenticular surgery. One surgeon shares his four-step approach to excellent functional results and high patient satisfaction.

Patients with uveitis who require cataract surgery present challenges to the surgeon at every stage of care. The uveitis must be controlled carefully preoperatively, small pupils are especially problematic during surgery, and inflammation must be controlled postoperatively.

Supranuclear gaze palsy should be suspected in patients with bilateral and symmetric vertical or horizontal gaze difficulty. Use of specific maneuvers to bypass the supranuclear input to the ocular motor nuclei can help to establish a supranuclear localization to the problem and direct neuroimaging to the supranuclear pathways in the brain and brainstem.

An analysis of results achieved from performing LASIK with a 213-nm solid-state refractive laser (Pulzar Z1, CustomVis) in 10 eyes with high and mixed astigmatism (mean astigmatism, –5.2 D) demonstrate its safety, predictability, and efficacy. Uncorrected visual acuity after a minimum of 8 weeks' follow-up was 20/30 or better in 100% of eyes.

An iris-fixed phakic IOL (Verisyse/Artisan, Advanced Medical Optics) is effective in correcting high myopia, hyperopia, and astigmatism, according to 5-year follow-up data from a prospective study conducted in France.

Customized IOL implantation has become a topic of great interest over the past year. The combined implantation of two different multifocal lenses, an apodized diffractive lens (AcrySof ReSTOR, Alcon Laboratories) and a refractive lens (ReZoom, Advanced Medical Optics), has provided patients with good results in near, intermediate, and distance vision because the two IOLs complement one another. In a survey of patients in whom the diffractive lens had been implanted bilaterally and patients in whom one of each IOL had been implanted, the combination approach received higher marks compared with bilateral diffractive lens implantation.

Several situations are associated with a high risk of failure after donor corneal transplantation. Encouraging results have been seen with a particular keratoprosthesis (Boston KPro, Massachusetts Eye and Ear Infirmary) as an alternative in carefully selected eyes.
