    We encountered a case of deformation 1 year after cataract surgery in which the supports were lifted toward the anterior capsule due to excessive contraction of the anterior capsule. We investigated the mechanism of onset of this condition. It was possible to observe the deformed ends of the haptics from the pupillary margin when the pupil was dilated. The intraocular lens (IOL) used in this case was an SA60AT (Alcon) and supportive fixation was performed at the 3 and 9 o'clock positions. The patient's medical history included uveitis caused by sarcoidosis. We measured the circumference of the transverse section of the crystalline lens using preoperative ultrasound biomicroscopy images from 3 to 9 o'clock. Subsequently, we created a simulation image of the IOL insertion into a space whose size was this circumference minus the diameter of the resection port in the anterior capsule in the same direction. The supports did not move along the horizontal axis as a result of contraction of the resection port in the anterior capsule. Rather, they deformed in such a way that they were lifted toward the anterior capsule and eventually assumed a position in which their ends could be observed from the pupillary margin when the pupil was dilated.

    Even if the newt removes lens surgically, the lens is regeneration at the dedifferentiation of iris pigment epithelium cell. Authors introduced the episomal vector into human iris tissue stem / progenitor cells and created induced pluripotent stem cells (iPS cells). The iPS cells derived from the iris were with positive at Alkaline phosphatase (ALP), Sox2 and SSEA-4. The iPS cells differentiated to lens epithelial cells using the rotary floating culture method. This result increased the αA-crystalline gene which was one of the markers of lens epithelial cells than the derivative previous method using the embryonic stem cells, and the cell aggregation which expressed the αA-crystalline protein was formed.
