EW NEWS & OPINION June 2016 23 performed to get through the thick and dense posterior plate. During sculpting, care was taken not to torque the phaco needle against the roof or sides of the incision, which would increase risk of a wound burn. Pieces were then torn off each lens Figure 1: Slit lamp view of the cataract Figure 2: Slit lamp image of patient's eye 1 month after cataract surgery Source: Steven Safran, MD half for phacoemulsification using a hybrid horizontal/vertical chopping/ shearing technique using a Sinskey hook as a second instrument and relatively high suction power to gain purchase on this extremely leathery nucleus. I found that lens pieces did not readily separate with chopping and that I had to tear the pieces off like I was dealing with rawhide. Fre- quent refills of the anterior chamber with dispersive viscoelastic were performed throughout the case to protect the cornea endothelium. At the conclusion of phaco the incision showed no evidence of heat-related contraction and thus no suture was required. Although the cornea had 2–3+ edema on day 1, by 1 week there were only trace Descemet's folds and vision had improved to 20/40 uncorrected. By 1 month the cornea was clear, and the patient was very satisfied with uncorrected 20/25 vision. Based on the responses from other surgeons it seems clear that ECCE in such a case is a reasonable option and one that even some of the most accomplished phaco surgeons would consider as their first-line approach. It does, however, carry an increased risk of choroidal hemorrhage, induced astigmatism, and ocular surface problems. It seems clear that there is little role for femtosecond laser-assisted nu- cleus disassembly in such a case as the laser cannot cut what it can- not visualize. In addition, a recent article has suggested that there may be increased risk of "suboptimal capsulotomy outcomes" when the femtosecond laser is used to create a capsulotomy in mature cataracts. 1 Manual phacoemulsification can also be successfully performed but with risk to the cornea endothelium and other ocular structures; that needs to be carefully avoided and with appropriate measures usually can be. Important considerations are the use of copious dispersive viscoelastic throughout the case to protect the cornea and a fresh sharp phaco needle to avoid wound burns and zonular damage.
