Summary

This is a prospective, multi-center, randomized comparative study. The purpose of the study is to evaluate and compare the postoperative visual outcomes and quality of vision of two diffractive trifocal intraocular lenses (IOLs) in patients with high myopic cataracts.

Detailed description

Binocular implantation of two types of trifocal IOLs was performed in patients with high myopic cataracts. Postoperative uncorrected distance (UNVA), intermediate (UIVA), near (UNVA), and best-corrected distance visual acuity (BCVA) were measured. Defocus curve, high-order aberrations, modulation transfer function curve, Strehl ratio and reading ability were compared between the two groups. The functional vision and incidence of photic phenomena were surveyed using questionnaires.

Conditions
