Changes of anterior chamber angle after posterior chamber intraocular lens implantation

Abstract

AIM: To observe the changes of anterior chamber angle after posterior chamber intraocular lens(ICL)V4c implantation for high myopia.METHODS: Prospective study. ICL V4c implantation was performed on 150 cases(300 eyes)with high myopia, and the changes of visual acuity, intraocular pressure,vault and anterior chamber angle were recorded before and 1d, 1mo, 3mo, 6mo and 1a after operation. Repeated measurement analysis of variance and LSD-t test were used to analyze the data.RESULTS: After 1d, 1mo, 3mo, 6mo, 1a operation, the recovery of UCVA was significantly higher than that before operation(F=98.2, PF=108.256, 112.342, 164.856, 316.549, 115.338, PF=102.68, 548.47, 93.37, 316.549, 117.698, all PPP>0.05).CONCLUSION: After ICL V4c implantation, the anterior chamber angle parameters in the horizontal direction of 1d, 1mo, 3mo, 6mo and 1a were smaller than those before operation, and tended to be stable after 3mo.
