AIM: To compare visual function of patients with cataract and high myopia after implantations of aspherical and spherical intraocular lens(IOL).

METHODS: Forty-two eyes of cataract patients with high myopia were retrospectively analyzed. 22 eyes were implanted aspherical IOL and 20 eyes were implanted spherical IOL. All the patients uncorrected distance visual acuity(UCDVA)were >0.2. Vision, accommodative amplitude, contrast sensitivity(CS)were examined at 6 months after operation.

RESULTS: There were no significant differences in best-corrected distance visual acuity(BCDVA), best-corrected near visual acuity(BCNVA), accommodative amplitude between aspherical and spherical IOL(P>0.05). After 6 months, CS and glare contrast sensitivity(GCS)of the low and medium space frequency in implanted aspherical IOL were better than implanted spherical IOL(P<0.05), but there were no significant differences in CS and GCS of the high space frequency(P>0.05).

CONCLUSION: Cataract patients with high myopia, CS and GCS in implanted aspherical IOL are better than that of implanted spherical IOL.
