Instead of heading directly to the OR, however, laser patients first stop at a dedicated room for the laser portion of the procedure, which takes minutes to complete. Surgeons place a cataract-lens-like cone that's attached to the laser on top of the patient's cornea to start the critical incisions of cataract surgery. The incisions made with the laser are stable, meaning patients can sit upright and walk from the laser room to the OR (although most facilities transport them in a wheelchair). In the OR, surgeons use blunt instruments to fully open the laser incisions before inserting the phaco tip to fragment the lens, remove it and insert the new IOL. The second half of the laser procedure resembles conventional cataract surgery. Ming Wang, MD, PhD, has performed approximately 1,000 femtosecond laser cases since adding the technology about a year ago. The director of Wang Vision 3D Cataract and LASIK Center in Nashville, Tenn., sums up laser cataract surgery's main advantage in a single word: accuracy. Dr. Wang says that benefit is best realized during creation of the capsulorhexis — the large circular incision in the anterior lens capsule. To appreciate what surgeons face when operating manually, try freehand drawing a perfect circle on a piece of paper. Darn near impossible, right? Dr. Wang says studies have shown the capsulorhexis needs to offer predictable size and a precise diameter, and N O V E M B E R 2012 | O U T PAT I E N T S U R G E R Y M A G A Z I N E O N L I N E 4 3
