Montreal-In the clinical setting, night vision disturbances after LASIK cannot be predicted by pupil size, but rather are correlated with preoperative sphere and the photoablation optical zone size, said Mihai Pop, MD.

Columbus, OH-Age-adjusted approaches are needed for the evaluation and management of suspected orbital fracture in pediatric patients because children are different from adults, according to JDespite the introduction of more accurate IOL formulas and biometry instrumentation, cataract and refractive lens surgery have yet to achieve the ophthalmologist's ideal of perfect emmetropia in all cases.1-5 This limitation stems from occasional inaccuracies in keratometry and axial length measurements, an inability to assess the final position of the pseudophakic implant accurately in a fibrosing capsular bag, and the difficulty of completely eliminating pre-existing astigmatism despite the use of limbal relaxing incisions and toric IOLs.6,7 A new lens technology offers the hope of taking ophthalmologists one step closer to achieving emmetropia in all cases and also perhaps further improving the final result by addressing higher-order optical aberrations.

Columbus, OH-Age-adjusted approaches are needed for the evaluation and management of suspected orbital fracture in pediatric patients because children are different from adults, according to Jill A. Foster, MD.

CA-The FDA approval of gatifloxacin ophthalmic solution 0.3% (Zymar, Allergan) marks a milestone as the first fourth-generation fluoroquinolone to enter the ophthalmic market. The therapy for the treatment of bacterial conjunctivitis caused by susceptible strains of bacteria also has a unique mechanism to prevent development of antibiotic resistance, according to Allergan.

Taking outdoor activities to an extreme is a way of life for William L. Benedict, MD. Whether it's kayaking, mountain biking, or snow skiing, he is constantly pushing his skills to the limit.

S?o Paulo-A comparative study has demonstrated that the M2 130 Single-Use microkeratome (Moria, Antony, France) performs identically to its reusable counterpart, the conventional M2 110. In addition, the Single-Use microkeratome is significantly easier to use and allows greater visibility, according to Renato A. Neves, MD, director of Eye Care Oftalmologia LASER Vision Centers here.

In the past decade, porous orbital implants have become the implant of choice for many surgeons managing the anophthalmic socket after enucleation or evisceration. By permitting fibrovascular ingrowth, these porous implants are better able to resist infection, migration, and extrusion when compared with acrylic or silicone implants.

A craniocervical arterial dissection usually results from a tear in the intimal arterial layer. This tear allows the formation of a false lumen containing a clot, which can lead to thromboembolic complications (stroke). If the dissection is subintimal, stenosis of the artery is the likely end result. If it is subadventitial, the result is a "pseudo-aneurysm" (Figure 1).

Niagara Falls, Ontario-Switching to once-daily instillation of nedocromil sodium 2% ophthalmic solution (Alocril, Allergan) is an effective alternative for maintaining control of ocular symptoms of seasonal allergic conjunctivitis after acute relief is obtained with twice-daily administration, according to an environmental study conducted by Michael Alexander, MD.

This year's fierce winter is now about to bring a big dose of misery to the 60 million Americans who suffer from seasonal allergies. Experts predict a fast-peaking, intense spring allergy season. Moisture accumulated from heavy snow and excessive rain has nurtured mold, and will fuel tree-pollen production-all of which will trigger an early and severe allergy season.
