title: Outcomes of coaxial microincision cataract surgery versus conventional coaxial cataract surgery.
abstract: OBJECTIVE
  To compare the outcomes of coaxial microincision cataract surgery (MICS) with those of conventional coaxial cataract surgery.
  
  
  METHODS
  University Eye Clinic, Geneva, Switzerland.
  
  
  METHODS
  In a prospective study, 50 eyes of 50 patients with nuclear or corticonuclear cataract (grades 2 to 4 on the Lens Opacities Classification System III) were randomly selected to have cataract extraction through a temporal clear corneal incision using 1 of 2 techniques: coaxial MICS (25 eyes) or conventional coaxial cataract surgery (25 eyes). Coaxial MICS was performed through a 1.6 mm incision and conventional coaxial cataract surgery, through a 2.8 mm incision. In all cases, a flexible hydrophobic acrylic intraocular lens (Lentis L-303, WaveLight GmbH) was implanted. Intraoperative parameters were ultrasound time, surgical time, and total volume of balanced salt solution used. The best corrected visual acuity, corneal thickness, and endothelial cell count were evaluated preoperatively and postoperatively.
  
  
  RESULTS
  There were no relevant clinical differences between groups or perioperative complications in either group. The only statistically significant differences between the 2 groups were ultrasound time (P = .0002) and surgical time (P = .005).
  
  
  CONCLUSIONS
  Coaxial microincision cataract surgery was a safe and effective technique. Although ultrasound and surgical time were significantly higher with coaxial MICS than with conventional coaxial cataract surgery, the postoperative results in the 2 techniques were comparable.
