Long-term outcome of primary versus secondary intraocular lens implantation after simultaneous removal of bilateral congenital cataract.
Summary of "Long-term outcome of primary versus secondary intraocular lens implantation after simultaneous removal of bilateral congenital cataract."
Long-term outcomes of intraocular lens (IOL) implantation for congenital cataract in children under 2 years old are still undetermined.
We retrospectively reviewed all cases of bilateral congenital cataract who had undergone simultaneous bilateral cataract removal with posterior capsulotomy and central anterior vitrectomy between 1990 and 2010. Patients randomly underwent primary IOL implantation or secondary IOL implantation after a period of contact lens wear. The two groups were compared for visual outcome and complications during follow-up.
Cataract removal and primary IOL implantation was performed in 30 eyes (15 patients; nine males, six females) at a mean age of 6.8 ± 4.2 months. After 79.31 ± 63.4 months, best-corrected visual acuity (BCVA) was 0.53 ± 0.36 EDTRS LogMAR. In 36 eyes (18 patients, 11 males, seven females) the lens was removed at a mean age of 5.42 ± 2.80 months, and after 32.0 ± 6.1 months of contact lens utilization, secondary IOL implantation was performed. After 109.0 ± 33.8 months, BCVA was 0.54 ± 0.4 ETDRS LogMAR. The association between age at surgery and final visual acuity and the difference between the two groups concerning type of cataract at baseline, BCVA and refractive error at last visit, incidence of posterior capsular opacification, glaucoma, strabismus, and nystagmus during follow-up were not significant (p > 0.05). Myopic shift was more frequent in eyes undergone primary IOL implantation (p < 0.001).
Similar visual outcome and complications were observed during long-term follow-up after both primary and secondary IOL implantation following simultaneous bilateral congenital cataract removal with posterior capsulotomy and central anterior vitrectomy.

Medical and Biotech [MESH] Definitions
Lens Implantation, Intraocular
Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place.
Phakic Intraocular Lenses
Lenses, generally made of plastic or silicone, that are implanted into the eye in front of the natural EYE LENS, by the IRIS, to improve VISION, OCULAR. These intraocular lenses are used to supplement the natural lens instead of replacing it.
Insurance, Long-term Care
Health insurance to provide full or partial coverage for long-term home care services or for long-term nursing care provided in a residential facility such as a nursing home.
Presence of an intraocular lens after cataract extraction.
Hiv Long-term Survivors
Persons who have experienced prolonged survival of HIV infection. This includes the full spectrum of untreated, HIV-infected long-term asymptomatics to those with AIDS who have survived due to successful treatment.
