The treatment effect of intraocular lens ciliary sulcus implantation combined with posterior capsular incarceration of intraocular lens on children with traumatic cataract

Objective

To compare the treatment effect of intraocular lens ciliary sulcus implantation combined with posterior capsular incarceration of intraocular lens and simple intraocular lens ciliary sulcus implantation.

Methods

We retrospectively analyzed 60 eyes of 60 children with traumatic cataract from June 2012 to June 2015 in the Second People’s Hospital of Yunnan Province, including 44 males and 16 females and the average age ranged from 1 to 14 years.The patients were divided into two groups according to the situation of posterior capsular, 30 eyes of 30 children for each group.The patients in combined surgery group were performed intraocular lens ciliary sulcus implantation combined with posterior capsular incarceration of intraocular lens, and the patients in simple surgery group were performed simple intraocular lens ciliary sulcus implantation.The follow-up time ranged from 1 month to 6 months.The best corrected visual acuity(BCVA), grade of optic axis turbid, dislocation of intraocular lens, postoperative complications and surgical duration were compared between the two groups.

Results

The BCVA after surgery was significantly different from that before surgery in both groups (combined surgery group: χ²=7.548, P<0.05; simple surgery group: χ²=5.579, P<0.05). The postoperative turbidity of central axis area and BCVA were not significantly different between the 2 groups (χ²=0.362, P>0.05). The dislocation degree of intraocular lens and proportion of postoperative complications were lower in the combined surgery group than those in the simple surgery group(χ²=9.858, P<0.05; χ²=7.200, P<0.05). The duration of surgery was not significantly different between the 2 groups (χ²=0.658, P>0.05).

Conclusions

Posterior capsular incarceration of intraocular lens has fewer complications, lower dislocation degree of intraocular lens and more effective for children with traumatic cataract than intraocular lens ciliary sulcus implantation.
