Effect of MI60 intraocular lens on anterior chamber septh and visual acuity of cataract patients with high myopia after intraocular lens implantation

Abstract

Objective To investigate the effects of MI 60 intraocular lens on anterior chamber depth and visual acuity of patients with high myopia cataract after intraocular lens implantation. Methods Using prospective study method, 60 patients with high myopia cataract were divided into and observation group (30 cases, 46 eyes) and a control group (30 cases, 42 eyes). Both groups performed cataract phacoemulsification and intraocular lens implantation. The observation group used MI 60 intraocular lens, and the control group MA60MA intraocular lens. The postoperative complications as well as the anterior chamber depth, intraocular pressure, and BCVA before and 6 months operation were compare between the two groups. Results 6 months after operation, the anterior chamber depth was (4.82 ± 0.45) mm in the observation group(4.31±0.39)mm (P 0.05). 6 months after surgery, the incidences of BCVA 4.7 were 10.87%, 54.35%, and 34.78% in the observation group, and were 7.14%, 61.90%, and 30.95% in the control group (P>0.05). The incidence of postoperative complications was significantly lower in the observation group than in the control group (4.35% vs. 23.81%, P<0.05). Conclusions MI60 IOL and MA60MA IOL are consistent in the improvement of vision in patients with high myopia taking cataract implantation, but MI 60 IOL maintains a deeper anterior chamber depth and reduces postoperative complications.
