OPD: Implant Center
The aberrometrique review to quantify the optical effect of a surgical complication of the cataract surgery as the occurrence of a dislocation of the artificial lens implant (implant pseudophake). A patient, cataract surgery, complains of severe discomfort in night vision, glare, halos, bright streaks, impossibility of driving at night. Visual acuity is measured at 10/10 with a slight correction astigmatism, but without this correction reduces the Visual symptoms, which are mitigated the day; the patient however noted a split on the side vision. This variation is consistent with the possibility that a high rate of optical aberration of high degree can be the cause of these symptoms.
(Biomicroscope) slit lamp inspection reveals the presence of a shift of the implant.
The measure by the topographer aberrrometre OPD SCAN 3 reveals the increase in the rate of the high degree of internal origin aberrations (implant).
The statement of the Wavefront accredits the internal origin of the aberrations of high degree, caused by the shift of the intra ocular implant. The maps that explore the optical quality of the eye allow to appreciate the effect of these aberrations on the quality of the retinal image:
Aberrometrique review, faced with clinical data, allows to incriminate the decentering of the implant with Visual symptoms. A reconstructive surgery to refocus the implant to the pupil is then performed:
This procedure, performed under local anesthesia, results in the disappearance of the Visual symptoms (duplication, halos, etc.). Review by OPD confirms the improvement of the optical quality of the eye:
This case illustrates the value of the OPD in the "complicated" cataract surgery case (in this case, the implant was not been positioned properly because of the occurrence of a breach of the cristallinienne capsule during the initial response). The parallelism between subjective symptoms and objective elements (the shift management and direction of the double vision, optical aberrations of high degree of coma guy) helped confirm the responsibility of the shift in the genesis of Visual annoyance.
