Complications

The list of complications below does not include complications that are related to the cataract removal. Only OriLens potential complications are discussed below. Eye doctor determines eyes diopter using instruments

Potential complications:

  1. Positioning of the mirrors, avoiding decentered mirrors: at the end of the surgery it is vital that the central mirror shall be positioned in the center of the pupil and the annular (posterior) mirror surface shall point outside towards the cornea with no tilt. In order to verify this, the pupil should be constricted and the posterior surface of the central mirror should clearly be seen centrally through the pupil.
  2. Late decentartion: if it is found that the central mirror is not centered during the first post-op examination or during any later examination, it should be repositioned into the proper location. Use appropriate means including surgery, if needed.
  3. Relation between the central mirror and the pupil: if the entire posterior mirror is not seen through the pupil, there is a possibility of a decentered pupil. Confirm that both loops are well positioned in the sulcus. If this is confirmed, then the lens is properly positioned and the problem may be related to the position of the pupil. In such a case, the pupil should be kept mildly dilated (one drop of diluted Atropine every 3-10 days) or pupiloplasty (laser or sphinctorotomy) should be considered.
  4. Post-op inflammation: any inflammation, even if not related to the surgical procedure itself, should be treated vigorously and immediately, including dilatation of the pupil in order to avoid synechia.
  5. Synechia: since the implant is mildly thicker than regular secondary lenses, posterior or anterior synechia should be avoided by dilating the pupil during the first few days after surgery and by follow up later.
  6. Wound closure: test for leakage and verify that the chamber is kept deep at all time.
  7. Lens inserted upside down (inverted): when properly positioned, the implant is implanted inside the eye so that the black (back) part of the central anterior mirror should face the cornea (the mirror faces the retina) and the posterior surface annular mirror should face outside towards you.
  8. Epithelial edema: this may be caused only by the surgical technique while inserting the lens into the posterior chamber.
