Implantation of a small-aperture intraocular lens and a partial aniridia implant in eyes with traumatic iris defects
Purpose: To report the clinical outcomes after implantation of a small-aperture intraocular lens (IOL) and a partial aniridia ring in three patients with traumatic iris defects. Observations: The corrected distance visual acuity (CDVA), irregular astigmatism, and glare improved in all patients. In o...

| description | Purpose: To report the clinical outcomes after implantation of a small-aperture intraocular lens (IOL) and a partial aniridia ring in three patients with traumatic iris defects. Observations: The corrected distance visual acuity (CDVA), irregular astigmatism, and glare improved in all patients. In one patient, the monocular defocus curve showed a visual acuity (VA) of 0.30 logMAR or better from 1.0 to −1.5 D, and the halo size and intensity were 5 and 10 (on a scale from 0 to 100), respectively, and the glare size and intensity were 23 and 16 (on a scale from 0 to 100), respectively. Conclusions and importance: The pinhole effect of the small-aperture IOL helped considerably decrease irregular astigmatism and improve visual acuity. The partial aniridia implant also contributed to the reduction of the glare symptoms, while allowing a sufficient fundus assessment. The combined implantation of the small-aperture IOL and the partial aniridia device, therefore, presents an effective option for improvement of the visual symptoms in patients with traumatic iris defects. |
