Abstract

Objective: To evaluate the ratio and performance of anterior capsular fibrosis after phacoemulsification surgery with intraocular lens (IOL) implantation and some related factors. Subject and method: Pseudophakic eyes had been operated by phacoemulsification technique at Vietnam National Institute of Ophthalmology in the period from 1 January 2012 to 31 December 2012 were included in our study. Method: Analytical cross sectional description. Patients were examined and diagnosed performance of anterior capsular fibrosis after pupil dilatation.  Result: 206 eyes of 168 patients with an average age of 69.2 ± 5.8 were included in the study. Anterior capsular fibrosis accounted for 95.1%, but 96.6% of cases were mild (55.3% mild, 23.8% moderate and 12.6% advance), only 3.4% at severe level. The rate of anterior capsular fibrosis was lower than in the group implanted by IOL, whose material is hydrophobic covered by heparin. IOL’s location or IOL’s haptic increased the severity of postoperative anterior capsular fibrosis. Conclusion: After the phaco surgery with IOL implantation, the ratio of anterior capsular fibrosis was high but most of cases did not affect eyesight. Heparin hydrophobic material group has the lowest rate of anterior capsular fibrosis.
