    Nov 7 2025 by SHRADDHA RAJ SHRIVASTAVA

    Right eye anterior segment slit-lamp image of a 30 year old male, who was operated for spontaneous bilateral inferior subluxation of crystalline lens. Primary surgery was performed almost 20 years ago in which lens extraction was done followed by IOL placement in bag after stabilising it with Cionni ring. The patient presented to us recently with right eye diminution of vision and was noted to have inferiorly subluxated IOL-capsular bag complex, with vitreous in AC coming from the superior aphakic area. Interestingly, we have also captured in this image - the capsular tension ring (Cionni ring) with its central fixation eyelet.
