Background: We report a case of spontaneous lens dislocation into the anterior chamber in a patient.
Case Report: We present a-75 years- old woman with a lens that was spontaneously dislocated into anterior with corneal touch and secondary glaucoma. The patient’s complaints included decreased vision and severe pain in the right eye. On evaluation, the vision was observed to be limited to detecting hand motions, and the intraocular pressure was 70 mmHg. The intraocular pressure remained elevated after medical therapy, and the patient underwent intracapsular cataract extraction, anterior vitrectomy and peripheral iridectomy. After intracapsular cataract extraction, the final visual acuity was 20/50 and intraocular pressure 12 mmHg.
Conclusions: We present in this report a case who was treated succesfully with intracapsular extraction and anterior vitrectomy in the spontaneous anterior lens dislocation.
