Factors affecting visual outcome in children following uniocular traumatic cataract.

The correction of paediatric traumatic aphakia remains a controversial topic. This study examines retrospectively the visual outcome in 32 children with uniocular traumatic cataracts. Fifteen received intraocular lens implants following lensectomy, and 17 received aphakic contact lenses. Age range was 2-14 1/2 years at the time of injury. The maximum follow-up time was 13 years. Twenty-four children obtained a good visual result (6/5 to 6/18). These were equally divided between those receiving intraocular lens implants and those with contact lenses. Factors adversely affecting visual outcome are discussed. These include complex trauma, delay in referral for lensectomy, inadequate postoperative correction of aphakia, contact lens difficulties and problems with occlusion therapy. Although aphakic correction with intraocular lens implants may require several subsequent surgical procedures such as capsulotomy, we advise early lensectomy and intraocular lens implantation where possible, particularly in young children with traumatic cataracts. This eliminates contact-lens-associated problems and maximises the chance of good visual outcome and retention of stereoscopic vision.
