Three combinations of IOLs for the correction of presbyopia were evaluated in a retrospective analysis. The results favored a mix-and-match approach using the (AcrySof ReSTOR, Alcon Laboratories) and the crystalens (crystalens, eyeonics) for better range and quality of vision, according to one surgeon.

In patients who have suffered multiple immunologic graft rejections, the chance of providing good-quality vision is dramatically increased with a keratoprosthesis than another transplant. Patients who receive a keratoprosthesis have rapid visual return, a good quality of vision, and a high rate of graft survival.

Bilaterial implantation of a refractive multifocal IOL (ReZoom, Advanced Medical Optics) can result in high satisfaction rates among patients undergoing cataract surgery or refractive lens exchange when proper patient selection, aggressive correction of residual refractive error, and early intervention for posterior capsule opacification are part of the strategy, according to a retrospective study of 71 patients.

An Ectasia Risk Factor Score System developed by researchers at Emory University appears to be a valid method for identifying patients at risk for ectasia after LASIK, according to a retrospective review of 171 cases of post-LASIK ectasia and 186 controls with normal postoperative courses.

A technique for obtaining digital photographs under standardized conditions was developed as the foundation for scientific assessment of IOL glistening size and severity, which ultimately will be used to investigate visual impact.

A novel prosthetic device (Boston Scleral Lens) is custom-designed to vault the cornea over an oxygenated reservoir of artificial tears. It is designed to correct corneal first surface aberrations and address symptoms of dry eye disease.

Evaluation of low contrast sensitivity outcomes after wavefront-guided refractive surgery in U.S. Air Force aviators shows quality of vision returns much faster after LASIK compared with PRK.

An aberrometer is being developed to provide cataract and refractive surgeons with a tool for intraoperative assessment of refraction to improve results of astigmatic correction techniques and IOL power selection. Outcomes in an ongoing clinical trial are encouraging.

Intracameral injection of cefuroxime significantly reduced the risk of endophthalmitis following cataract surgery when compared with subconjunctival injection in a single-center study.

Multiplex ligation probe amplification (MLPA), a relatively new technique for detecting copy number variations in genomic sequences, has been used to study the pathomechanism of autosomal dominant optic neuropathy.

Research using a conditional knockout mouse model of the mitofusin 2 gene are providing insights into the optic nerve damage sometimes associated with Charcot-Marie-Tooth disease. Results to date show degenerative changes in the retrobulbar optic nerve suggesting a response to a neurodegenerative injury.

Twenty-five-gauge sutureless vitrectomy is has gained a respectable niche among retinal surgeons, with a dramatic increase in use over the previous 4 years.

Twenty-three gauge transconjunctival sutureless vitrectomy performed in pseudophakic eyes offers faster recovery times and increased patient comfort regarding suture-related and sclerotomy-related complications, according to one surgeon.

Cryotherapy applied to treat retinal holes may be associated with the development of sympathetic ophthalmia.

Improvements in visual outcomes remained stable in a group of patients with age-related macular degeneration who were switched from therapy with intravitreal bevacizumab (Avastin, Genentech) to intravitreal ranibizumab (Lucentis, Genentech).

Up to 90% of children with fetal alcohol syndrome have eye abnormalities such as optic nerve hypoplasia and tortuosity of the retinal blood vessels. Because ocular findings are so common, an eye examination can be useful in helping diagnose fetal alcohol syndrome.

Occluding the sound eye in amblyopic patients provides rapid and lasting visual acuity improvement.

Once thought to be a disease characterized solely by elevated IOP, the definition of glaucoma has been evolving to more accurately portray the disease's true nature.

Current IOP measurement techniques have limited accuracy and do not allow for 24-hour monitoring. A system based on a small, implantable passive transducer and external probe is being developed to address these limitations.

Implantation of a miniature glaucoma device (Ex-PRESS R-50, Optonol) under a scleral flap is a modification of trabeculectomy that appears to provide similar IOP-lowering efficacy but with fewer complications.

A trabecular bypass micro stent (iStent, Glaukos) was developed to restore fully natural physiologic outflow in glaucomatous eyes by allowing flow of aqueous from the anterior chamber into Schlemm's canal.

Biosyntrx Corp. is partnering with Wellosophy Corp. to include a professional-strength version of a proprietary hydrogel gastric bulking technology (Swell) into Biosyntrx's new mealtime portion-control product (Avantrx).

Bausch & Lomb introduced the fourth generation of the only FDA-approved accommodating IOL (Crystalens HD) in Europe at the annual meeting of the European Society of Cataract and Refractive Surgeons.

Alcon Inc. announced the commercial launch outside the United States of its new +3 add power aspheric lens (AcrySof ReSTOR) during the annual meeting of the European Society of Cataract and Refractive Surgeons.

Novartis Pharmaceuticals Corp. has launched the Patient Assistance Now Web site and telephone service to integrate company programs and other resources to help uninsured Americans pay for their Novartis medicines and find health-care information.

iScience Interventional has received expanded 510(k) clearance from the FDA to allow ophthalmic surgeons to use its microcatheters to enlarge outflow passages to reduce IOP in the treatment of primary open-angle glaucoma.

A moderate correlation has been found between optical coherence tomography and fundus photo measurements as well as between those measures and visual acuity in the assessment of diabetic macular edema.

Currently, surgeons are employing combination techniques of bone and fat decompression to treat thyroid eye disorders, depending on the clinical situation. Prospective studies are needed to establish the ideal operative approach to minimize postoperative complications with the best cosmetic outcome in mind. Despite the multiple options available, it is most important to tailor the surgical approach to meet the individual needs of the patient.

Allergan Inc. has launched a new national dry eye campaign with the Red Hot Mamas, a menopause education provider.

Othera Pharmaceuticals Inc. has begun dosing in a phase I/II multicenter, investigator-masked clinical trial of the safety and efficacy of a topical drug (OT-730) in reducing IOP in subjects with ocular hypertension or open-angle glaucoma
