This is where the focus of one eye is set for distance and the other for intermediate and some near vision such as computer use. Glasses for are still likely needed for comfortable near work or prolonged intermediate vision tasks.
Monovision works well if you are already used to this with previous monovision contact lens use. Monovision doesn’t suit everyone and may require some months of adaption after the surgery. Mr Alex Day’s premium monofocal lens of choice provides excellent distance vision and significantly better intermediate vision (measured at 66 cm) when compared to a basic monofocal lens.
Multifocal lens are those with multiple focal points, so providing distance and middle vision, and some near. Multifocal lens work well in people who want to minimise the need for reading glasses and are prepared to accept some compromise as even with the latest advanced multifocal lens there may still be a mild glow or halo around lights or glare in some lighting situations. Multifocal lens work best with femtosecond laser assisted surgery as the laser can be used to reduce any pre-existing astigmatism. Multifocal lens are not suitable for people with eye conditions such as retinal problems macular degeneration, or diabetic retinopathy, or those with glaucoma.
Extended depth of focus (EDoF) lens are the next generation in multifocal lens design. These provide greater spectacle independence than monofocal lens, but with less optical side effects such as glare and halos that traditional multifocal lens have. Mr Alex Day’s EDoF lens of choice provides excellent vision for everyday activities such as driving and also computer work, using a mobile or reading price tags. Glasses may still be needed for night driving and for reading small print or other near tasks.
Mr Alex Day will specifically advise you about your situation and the lens choices available.
