About this study

  • Heparin surface treatment lens can reduce inflammatory reaction.
  • Modified aspheric lens are more in line with human optical properties than the traditional aspheric lens.
  • To obverse the effect of this type lens in the same as traditional aspheric intraocular lens at the same time, whether can further improve the effects of operation.
  • After one day, one week, one month, three month follow-up，Key observation on the flare, the optical quality, contrast sensitivity and other parameters.Study the postoperative inflammatory reaction with test group lens，and the impact on the visual quality.
