OBJECTIVE: To observe the long-term outcomes after congenital cataract surgery performed prior to 36 months of age. METHODS: A retrospective case study was conducted. Thirty-two cases (57 eyes) of congenital cataract were included from January 2004 to January 2012. All patients received intraocular lens (IOL) implantation with posterior continuous curvilinear capsulorhexies and anterior vitrectomy after cataract extraction and were followed up. At the last visit, the best corrected visual acuity (BCVA) was determined and postoperative complications were evaluated during follow-up with a longest time of 13 years. Non-normal distribution showed in median M (minimum and maximum). Data were analyzed by Kruskal Wallis single factor variance analysis and multiple comparison. The independent Mann-Witney U test was used to analyze non-normal distribution data. RESULTS: There were thirty-two cases (57 eyes) of congenital cataract including 7 unilateral cases and 25 bilateral cases. The median age at cataract extraction was 6.0months; the median IOL implantation age was 28.0 months and the median duration of follow-up after cataract extraction was 67.0 months. The median postoperative BCVA was (LogMAR) 0.52. Unilateral and bilateral cataract postoperative BCVA difference had no statistical significance (U=107, P>0.05). Patients received cataract surgery in 2 to 4 months, the postoperative BCVA was better than in 5 to 8 months. The difference was statistical significance (H=-15.33, P<0.05). BCVA after IOL implantation before 24 months were significantly better than after 30 months. The difference had statistical significance(H=-20.61,-20.78, P<0.05). Postoperative complications were posterior capsular opacity (5 eyes; 8.77%), glaucoma (2 eyes; 3.51%), strabismus (17 eyes; 29.82%) and nystagmus (30 eyes; 52.63%). CONCLUSIONS: Most infantile cataract surgeries performed prior to 36 mouths of life together with the implantation of IOL can achieve good visual acuity. No serious complications occurred.
