San Francisco-Higher-order aberration interactions can occurwith customized ablations, regardless of the laser platform. Withthe development of a new nomogram, University of Rochesterresearchers have been able to neutralize these interactions,providing more predictable visual outcomes, explained Scott M.MacRae, MD, during the American Society of Cataract and RefractiveSurgery annual meeting.

San Francisco-Inferior placement of a single intrastromalcorneal ring segment (Intacs, Addition Technology) appears toafford better outcomes than double-segment placement when treatingkeratoconus and ectasia in eyes with peripheral (paracentral)cones, said Colin C.K.

San Francisco-Topography detects the early curvature changeson the anterior corneal surface. And these are precisely thechanges that need to be heeded in patients undergoing refractivesurgery.

Oklahoma City, OK-Ferreting out the causes of diplopia can betricky. To make the task easier, R. Michael Siatkowski, MD,outlined his four steps to finding the causes of diplopia and sevenrules that all cases should follow.

Lund, Sweden-The effect of cataract surgery for improvingvisual function decreases over time, but a high proportion ofpatients continue to enjoy the benefits of surgery up to 8 yearsafter the procedure, according to a study undertaken by Swedishophthalmologists.

San Francisco-Advanced surface treatment (AST) with the Epi-Kkeratome (Moria) is a significant advance in laser visioncorrection but necessitates special attention to pain relief andvisual recovery, said Henry "Rick" Milne III, MD, a refractivesurgeon in Columbia, SC, who has performed more than 300 cases withthis technique.

Analyses of flap thickness showed favorable predictability.

An impressive track record with the Dohlman-Doane Bostonkeratoprosthesis in adults at high risk for corneal transplantationhas motivated corneal surgeons to use the device in pediatric eyeswith corneal opacities, and the outcomes in those young patientshave been very encouraging.

What is your contact lens image?

Invite patients to try contact lenses at no obligation.

The primary disadvantage of frequent-replacement contacts isoverwear.

San Francisco-Thin-flap LASIK with the K-4000 microkeratome(Becton Dickinson) is safe and delivers flaps that aresignificantly thinner than with other available heads. Thin-flapLASIK is the preferred choice with the K-4000 microkeratome,according to Rupal S. Shah, MD.

Mild haze (graded as 1.5 on a scale of 0 to 4 with higher scoresindicating more haze) was present the first day after surgery,which decreased by the fourth postoperative day to 0.5.

Studies evaluating the new Zyoptix XP microkeratome (Bausch &Lomb) indicate that it performs safely and reliably to cut LASIKflaps of a reproducible thickness with a standard deviation thatmatches or exceeds results reported for the femtosecond laser(IntraLase).

Barranquilla, Colombia-Mechanical microkeratomes have anumber of advantages compared with the femtosecond laser"macrokeratome" and should continue to be regarded as safe andefficient instruments for LASIK flap creation, according to CesarA. Carriazo, MD.
