Frequently Asked Questions Print E-mail
  • How do I know if  I am eligible to have the NewIris procedure?
    Ocular pathologies must first be ruled out.  Specific parameters like eye pressure, anterior chamber depth, gonioscopy and corneal health need to be examined by a comprehensive ophthalmologist.  Results are sent to Kahn Medical to determine eligibility. 
  • Will myopia, astigmatism and other refractive errors exclude me from having the procedure?
    No, but NewIris is not refractive and pre-op and post-op vision may remain the same.  Patients may continue to wear prescription glasses or contact lenses as before.  Lasik may be feasible in selected patients.
  • How long is the recovery period?
    Patients are asked to stay for one week for surgery and post-op follow-up.  Vision is expected to remain blurry between two to four days after the procedure.  Antibiotics and anti-inflammatory eye drops are prescribed during this period.  Results are natural and patients are able to return to their normal activities after this time. 
  • Is the procedure painful?
    The procedure is not painful.  It is ambulatory and performed under topical anesthesia. 
  • Can anyone tell I have a faked color like by contact lenses?
    Results are so natural that only your ophthalmologist under slit lamp examination can detect the implants.
