Progressive hyperopic refractive changes after posterior capsule tear following blunt ocular trauma.

PURPOSE: To describe the mechanism of progressive hyperopia and its management in the long-term course of traumatic cataract with a posterior capsule tear (PCT) following blunt ocular trauma.

OBSERVATION: A 37-year-old woman presented with blurry vision and photophobia after being hit in the right eye by a slipper. She was found to have PCT with the formation of a traumatic cataract with emmetropia (0 diopters [D]). Three years after the injury, a broader hyperopic change of +8.0 D was found in the patient at her first visit to our clinic. Optical coherence tomography (OCT) analysis of the anterior segment of the eye revealed damage to the posterior capsule and cataracts due to disorganization of the lens fibers and liquefaction of the lens. Femtosecond laser-associated cataract surgery was performed for anterior capsulotomy and segmentation of the nucleus without further enlargement of the PCT, facilitating the placement of a capsular tension ring segment and a multifocal intra ocular lens (IOL) in the capsular bag. At 1-month post-operation, her uncorrected visual acuity was 20/20 in the right eye, with a well-centered IOL.

CONCLUSIONS AND IMPORTANCE: Isolated PCT due to blunt trauma is rare, and there have been no reports of progressive hyperopia after three years of follow-up. In such cases, the lens may liquefy, resulting in decreased refraction and significant hyperopia.
