Description

  • Patients with cataracts have cloudiness of the lens that impairs vision.
  • It must be replaced with a prosthetic lens however the lens’ refractive power has to be calculated using formulas to predict the kind of lens that will be implanted for best visual outcomes.
  • Patients that have had prior refractive surgery of the cornea do not have as good refractive outcomes after cataract surgery.1
  • The concern is that there is not a goldstandard formula that can be used for this population to predict the refractive power of the lens that should be implanted.
  • Optiwave refractive analysis (ORA) is a new technology that is supposed to better predict refractive power of the implanted lens for patients with a history of refractive surgery.
  • Newer formulas have also been developed to try to address this.
  • We plan to determine whether ORA or newer generation formulas are more accurate in predicting refraction for cataract surgery patients with a history of refractive surgery.
