AB  - PURPOSE: To compare surgical parameters among eyes undergoing laser-assisted 
      cataract surgery (LACS) using different lens fragmentation patterns (LFP). 
      METHODS: Prospective, randomized, unmasked clinical trial. One-hundred eyes 
      underwent LACS and were randomly assigned to 1 of 3 LFP treatment groups: (1) 
      laser capsulotomy only; no lens fragmentation (NLF) (n = 34); (2) three-plane 
      chop (TPC) (n = 33); and, (3) pie-cut pattern (PCP) fragmentation (n = 33). 
      Prechop phacoemulsification (PHACO) was performed on all eyes using the same 
      femtosecond (FS) laser and active-fluidics PHACO machine. MAIN OUTCOME MEASURES: 
      FS laser dock time (s), PHACO time (s), PHACO power (%), cumulative dissipated 
      energy (CDE) (%-s), irrigating fluid volume, and operative time. RESULTS: The 3 
      treatment groups were comparable in terms of patient age (P = 0.164) and nuclear 
      density (P = 0.669). FS dock time was higher in the PCP group (184.18 +/- 25.86) 
      compared to the TPC (145.09 +/- 14.15) group (P < 0.001). PHACO time was 
      significantly shorter in the PCP (23.19 +/- 17.20 s) compared to TPC 
      (35.27 +/- 17.70) and NLF (46.15 +/- 23.72) groups (P < 0.001). PHACO power was lower 
      in the PCP (11.81 +/- 3.71) compared to the NLF (14.41 +/- 1.88) and TPC 
      (14.04 +/- 2.46) groups (P < 0.001). CDE was lower in the PCP (2.85 +/- 2.32) 
      compared to NLF (6.55 +/- 3.32) and TPC (6.55 +/- 5.45) groups (P < 0.001). Fluid 
      volumes and operative times were similar. CONCLUSION: LFP can influence PHACO 
      surgical parameters. Extensive fragmentation patterns such as PCP appear to lower 
      PHACO time, power, and CDE and may potentially reduce the risk of PHACO related 
      complications.
