All patients were operated in the same fashion by the same surgeon. All patients received topical anesthesia by lidocaine 2% gel before surgery. A 2.75 mm self-sealing clear cornea incision was made on the temporal side. Viscoelastic solution of sodium hyaluronate 3% and chondroitin sulfate 4% (Viscoat®) was used to reform and stabilize the surgical planes and protect the endothelium. A 5.00 to 5.25 mm continuous curvilinear capsulorhexis was initially performed with a 26-gauge needle and completed with forceps. The nucleous was removed without intraoperative complications such as posterior capsule rupture. Phacoemulsification was performed using the Infinite (Alcon Surgical) or Sovereign machine (Allergan Surgical). All IOLs were inserted in the capsular bag with the injector system. The viscoelastic material was completely removed at the end of the procedure. No sutures were used in any case. After 1 week the patient had the fellow eye operated. Postoperative medication included moxifloxacin (Vigamox®) or gatifloxacin (Zymar®) 4 times a day for 2 weeks, 0.1% diclofenaco sodium (Voltaren) 3 times a day for 4 weeks and steroid (Predfort) eyedrops 4 times a day for 6 weeks. Postoperative follow-up was 1 day, 1 and 3 months.
