Sutured posterior chamber intraocular lenses for traumatic cataract in Africa

摘要

The management of unilateral traumatic cataract with inadequate zonular integrity or capsule support poses unique challenges to surgeons. Contact lenses and anterior chamber intraocular lenses (AC IOLs) for aphakic rehabilitation, despite being respectively less invasive and technically easier to implant, are not appropriate in all patients. A sutured posterior chamber IOL (PCIOL) may be safer because it does not further compromise traumatized angle structures.Suturing PC IOLs is time consuming and intricate. In low-income countries, such as South Africa, indigent patients with unilateral posterior segment ocular trauma and guarded prognoses are often denied intervention. Similarly, one may argue that such unilateral anterior segment interventions are inappropriate. This study was performed to determine whether the visual results of sutured PC IOLs for traumatic cataract justify this intervention in middle-income and low-income settings.
