  • Abstract
  • Look Inside

A 76-year-old female presented with left ocular pain and headache since one week before. She had been diagnosed with cataract 10 years before. Her visual acuity was 0.9 right and counting fingers left. The intraocular pres-sure was 17mmHg right and 25mmHg left. The left eye showed corneal edema and inflammation in the anterior cham-ber. Remnants of disrupted lens capsule were seen in the pupillary area. The lens nucleus was present posterior to the pupil. The anterior vitreous was turbid. We diagnosed her with spontaneous dislocation of lens nucleus following ma-ture cataract. We extracted the lens nucleus through a corneoscleral wound after bringing the nucleus into the anterior chamber. The disrupted lens capsule and vitreous opacity were removed by vitrectomy. The dislocation of lens nu-cleus seemed to be due to fragile lens capsule and zonules in long-standing mature cataract.
