We present two cases for which intraocular pinhole implants were used to treat irregular corneal astigmatism after planned and unplanned posterior capsule opening during cataract surgery. The first case had a fibrotic posterior capsule that was eliminated with a posterior capsulorhexis. After that, the intraocular lens (IOL) and pinhole were implanted in the capsular bag. In the second case, a posterior capsule tear after phacoemulsification was converted to a posterior capsulorhexis, allowing implantation of an IOL in the capsular bag and the intraocular pinhole in the ciliary sulcus. With this method, irregular astigmatism in both cases could be managed with the intraocular pinhole very effectively. The implants remained stable and well centered in both cases and no complications were noticed.

Purpose: The IC-8® Apthera™ (AcuFocus Inc.™, Irvine, California, USA) is the first small aperture intraocular lens (IOL) to receive FDA approval for presbyopia correction in the summer of 2022. It is a single-piece hydrophobic acrylic monofocal lens, which is placed in the capsular bag.

Introduction: Pinhole intraocular lenses (IOLs) were developed to improve reading by compensating for loss of accommodative function. The IC-8 Apthera™ is a small-aperture presbyopia-correcting IOL that combines the proven principle of small-aperture optics with an aspheric monofocal lens to deliver a continuous range of vision for patients with cataracts from distance to near vision. Posterior capsule opacification is the most common sequela after cataract surgery.

Background: Congenital microcoria has been extensively reported and usually leads to visual dysfunction or blindness. However, micropupil development secondary to cataract surgery has never been reported. Here, we describe a rare case of micropupil development in infancy that occurred secondary to combined cataract extraction and intraocular lens implantation for treatment of congenital cataract.
