AIM: To elevate the stability of Bigbag intraocular lens(IOL)implanted for high myopia.

METHODS: In this prospective control trail, axial length ≥28mm of high myopia with or without cataract patients in our hospiotal from May 2012 to February 2014 were selected. They were divided into two groups and were implanted with Bigbag IOL or Sensar IOL after phacoemulsification surgery. After 6mo, complications and the status of IOL posterior capsule were observed, the differences of distance between posterior capsule and retina before and after operation(Δd)were compared.

RESULTS:Sixty-three eyes of 52 cases were included. There were 30 eyes of 24 cases(female: 19 eyes of 15 cases; male: 11 eyes of 9 cases)in the Bigbag group and 33 eyes of 28 cases(female: 19 eyes of 16 cases; male: 14 eyes of 12 cases)in the Sensar group. The Δd was 1.49±0.06mm in the Bigbag group and 1.67±0.09mm in the Sensar group, with statistically significant difference(P<0.01). At 6mo postoperatively, posterior capsule striae(PCS)were found in 2 eyes(6.7%)of Bigbag group and 9 eyes(27.3%)of Sensar group, with statistically significant difference(P=0.031).

CONCLUSION:The stability of Bigbag IOL is better than Sensar wiht low incidence of PCS. The Bigbag IOL is more suitable for high myopia.
