AIM: To investigate the visual recovery and complications in patients with traumatic cataract treated by intraocular lens Ⅰ phase implantation and Ⅱ phase implantation.

METHODS: Totally 86 patients with traumatic cataract(86 eyes)treated in our hospital from January 2014 to December 2016 were enrolled in the retrospective study, and they were divided into the control group(treated by intraocular lens Ⅰ phase implantation, 46 eyes)and the observation group(treated by intraocular lens Ⅱ phase implantation, 40 eyes). The general situation of surgery, the visual recovery at 6mo after operation and the incidence rate of complications in two groups were observed.

RESULTS:There were no significant differences in surgical time, intraoperative blood loss and hospitalization time between the two groups(P>0.05). There was no significant difference in the excellent and good rate of visual acuity between the two groups before operation between the twogroups(P>0.05). At 6mo after operation, the excellent and good rates of visual acuity in two groups obviously increased(P<0.05), while there was no significant difference in the excellent and good rates of visual acuity at 6mo after operation between the two groups(P>0.05). There was no significant difference between the two groups in the incidence rates of posterior capsule rupture and vitreous body prolapse(P>0.05). The incidence rates of corneal edema, iridocyclitis and posterior capsular opacification in the observation group after operation were significantly lower than those in control group(P<0.05).

CONCLUSION:The effects of IOL Ⅰ phase implantation and Ⅱ phase implantation are similar in patients with traumatic cataract, in terms of the general situation and improvement of visual recovery. However, the incidence of complications after Ⅱ phase implantation is relatively lower.
