Performance of Extended Depth of Focus (EDOF) multifocal SCL for intraocular lens implanted eyes
- Conditions
- IOL implanted eyes after cataract surgery
- Registration Number
- JPRN-jRCTs032200118
- Lead Sponsor
- Takahiro Hiraoka
- Brief Summary
The EDOF contact lens demonstrated better binocular visual acuity at intermediate and near distances but the far visual acuity was slightly affected. Regarding contrast sensitivity, the EDOF contact lens was generally worse than the single vision contact lens from middle to high spatial frequencies, but there was no difference at low spatial frequency (1.5cpd). Near stereopsis was significantly better in EDOF than single vision contact lens.
