Abstract: :
Purpose: To explore the visual outcome and complications of secondary intraocular lens in young traumatic cataract induced by open-globe and blunt injury, and to access the predisposing factor for functional vision. Methods: A retrospective series was performed and consecutive patients were enrolled between 1998 and 2002. Patient's characters, causes of injury, categories of the wound, timing and procedure of the primary repair, interval of subsequent IOL implantation, follow-up, postoperative complications were recorded Results: A total of 23 patients participated and all were males. Mean age was 33 years old. Nineteen in 23 cases (82.6%)were open-globed injury which all accident happened in the workplace and 4 in 23(17.4%) were blunt injury. All patients received cataract extraction which 20/24 (83.3%) were performed trans pars plana vitrectomy with lectomy or clear aspiration and 12/20 (60%)was performed foreign body removal simultaneously. Seven in 20 (35%) had more than once vitreoretinal surgery due to retinal detachment or crystalline lens dislocation. Mean of visual improvement after secondary IOL implantation was 3 lines of snellen acuity. Eight in 23 (34.8%) cases achieved 20/25 or more after the complicated subsequently surgeries. Mean follow-up is 9 months. However, there was 5 in 23 (21.7%) had visual deterioration or nor improvement due to central corneal scar, secondary glaucoma, macular pucker, and recurrent retinal detachment. Conclusions: 50% cases of traumatic cataract achieve functional vision after prompt surgical intervention and subsequent IOL implantation for open-globed and blunt injury. 21.7% developed complications. Accuracy and visual improvement were not correlated to location of injury for open-globed injury (P<0.05).
