title: Corneal topography after cataract surgery using a clear corneal incision closed with one radial suture.
abstract: OBJECTIVE
  To determine whether corneal topography and visual recovery are affected by suturing a temporal, clear corneal incision for cataract surgery.
  
  
  METHODS
  Forty-one consecutive phacoemulsification patients (39 eyes) had a 3.2-mm incision sutured with one 10-0 nylon, radial suture removed after 1 postoperative week. Visual acuity (VA) and corneal topography, including best fit sphere (BFS), best fit cylinder (BFC), principle meridian, topographic irregularity (TI), and vector-corrected astigmatism (VCA), were measured preoperatively and 1 day, 1 week, and 1 month postoperatively. Two-tailed t tests and Pearson correlations were calculated.
  
  
  RESULTS
  From the preoperative measurement to 1 week postoperatively, VA improved, BFS (P = .005) and TI (P = .033) increased, and VCA shifted with-the-rule. From 1 week to 1 month postoperatively, BFS (P = .012) and TI (P = .002) decreased. BFC and its direction did not change. Almost all measures were significantly correlated.
  
  
  CONCLUSIONS
  The benefits of sutureless surgery on corneal topography and visual recovery are not degraded by using a suture to prevent wound leakage.
