Since the lens is monofocal, the light can only be bent to one focus point at a time.With monofocal IOLs, the lens bends the light so that it will form a focus point on the retina of the eye.A surgeon can chose an IOL that focuses light best coming from distant objects, or a stronger powered IOL that focuses light better from near objects.However, light cannot be focused from both distant and near objects at the same time with a monofocal lens.The Crystalens accomplishes this by use of two small hinges, which allow the lens to move forward and backward slightly inside the eye.

These lenses reduce some of the distortions produced by older, spherical lenses.This guidance represents the view of NICE, arrived at after careful consideration of the evidence available.When exercising their judgement, healthcare professionals are expected to take this guidance fully into account, and specifically any special arrangements relating to the introduction of new interventional procedures.When light enters a monofocal lens, it is bent to a focus point.As the power of the lens becomes stronger, its ability to bend light more sharply is increased.

The guidance does not override the individual responsibility of healthcare professionals to make decisions appropriate to the circumstances of the individual patient, in consultation with the patient and/or guardian or carer.

  1. How can you get thicker skin about your height when society – and many men – are too intimidated to date a tall woman? For anyone who deals with sex or appearance issues, I always encourage them to be disciplined about getting some private naked time at home.
