Abstract Details


To present the results of 22 eyes with irregular astigmatism treated with a new pinhole intraocular implant, designed for supplementary sulcus fixation. Mean follow-up of 18 months.


University of Sao Paulo


This study was designed as a prospective interventional non-randomized self-paired case series to determine the safety and efficacy of a new pinhole intraocular implant, for the treatment of irregular corneal astigmatism. 22 eyes of 21 patients with irregular corneal astigmatism and disphotopic complaints (keratoconus, post-radial keratotomy and post-penetrating keratoplasty) were enrolled. The pre and post-operative examination included uncorrected visual acuity (distance, intermediate and near) under standardized luminance level of 85 candelas (cd)/m2; manifest refraction; anterior chamber depth and central keratometry (Pentacam, Oculus, Germany); endothelial cell count (CEM-530, Nidek, Japan); pupil diameter evaluation (Colvart pupilometer, Oasis, USA), and slit lamp evaluation.


All eyes had statistically significant improvement of UCVA as well as reduction of glare and disphotopias. The device was well tolerated and achieved proper centration in the ciliary sulcus.


This new pinhole intraocular implant was able to safely minimize the impact of corneal aberration in cases of irregular corneal astigmatism.
