title: Transient macular edema after laser in-situ keratomileusis.
abstract: OBJECTIVE
  To investigate the macular changes induced by laser in situ keratomileusisc (LASIK) procedure.
  
  
  METHODS
  Optical Coherence Tomography (OCT) was used to examine 27 eyes of 15 LASIK patients before surgery, and 1 day, 1 week, 1 month after surgery.
  
  
  RESULTS
  The mean thickiness of neuroepithelial layer of macula was (195 +/- 24) microns, (178 +/- 16) microns 1 day and 1 month after surgery, respectively, while the baseline was (174 +/- 12) microns. The increase in macular neuroepithelial thickness was correlated with the degree of myopia, but not with the duration of suction or the postoperative BCVA.
  
  
  CONCLUSIONS
  Mild macular edema is common in the first month following LASIK, especially in high myopia. However, no association with loss of BCVA has been established.
