title: Comparison of contrast sensitivity after implantation of diffractive lens SA60D3 and monofocal lens MA60BM.
abstract: OBJECTIVE
  Comparison of CSF in groups with diffractive lens SA60D3 and with monofocal lens MA60BM, and applying results to healthy population.
  
  
  METHODS
  The study included 3 groups of patients. First group consisted of 10 patients, who have undergone implant surgeries with diffractive lenses SA60D3 in both eyes; second group included 9 patients after implant surgeries with monofocal lenses MA60BM in both eyes. Third group included 10 patients with clear own lens. Groups were homogenous to number of patients, age and gender structure, as well as BCVA. CSF was determined for each eye. In the case of operated patients studies were performed 6 months after surgery. Homogeneity of groups was determined with Kruskal-Wallis test, but results of the studies were tested with variance. Results were shown in normalized CSF version.
  
  
  RESULTS
  In conducted studies there was no statistical difference in specific evaluated cpd (3, 6, 12, 18) between SA60D3 group and MA60BM group after 6 months from surgery (p = 0.892, p = 0.926, p = 0.564, p = 0.9953). The above results were obtained by testing variance at confidence level p < or = 0.01. At the higher confidence level p < or = 0.05 there was significant difference between SA60D3 group, MA60BM group and healthy control.
  
  
  CONCLUSIONS
  Diffractive lenses SA60D3 decrease CSF in comparable range as monofocal MA60BM lenses, which does not change acceptable standard for quality vision for monofocal lenses, that is currently accepted.
