Depending on the implant, what will be sharp without glasses?

Three vision thumbnails (near, intermediate, distance) showing what each implant makes sharp. From left to right: a page of reading for near vision, a computer screen for intermediate vision, a road sign for distance vision. Depending on the implant chosen, each thumbnail is sharp or blurred. The monofocal implant makes only distance sharp, the EDOF distance and intermediate, the multifocal all three distances. Glasses may still be useful for the blurred thumbnails.

Monofocal: distance vision is sharp without glasses. For reading up close, and often for the screen, glasses are still useful.

EDOF: distance vision and intermediate vision (screen) are sharp. Fine reading up close may still require glasses.

Multifocal: all three distances can be sharp without glasses. Halos are possible at night in distance vision; reading up close is more comfortable in good light.

Illustrative diagram. The choice of implant depends on the eye and on lifestyle; it is decided with the surgeon. Outcomes vary from patient to patient.
