Toric lenses provide good vision for one focal distance only, meaning the patient must choose whether to be more dependent on glasses for either reading or driving.Toric lenses use conventional spherical optics technology, meaning when the pupil is large as would occur with night-driving, dim lighting or in fog, some visual distortion and reduced contrast sensitivity will occur.
The ideal standard lens patient wants improved vision but does not want to pay for a premium lens, and accepts that night vision and vision in low-contrast lighting will be slightly reduced.
Patients selecting a standard lens must also accept that glasses will be needed for some or all activities.
Multifocal/Accommodating lenses are excellent foldable lenses that are implanted through small self-sealing incisions.
Multifocal/Accommodating lenses offer the possibility of seeing well at more than one distance, greatly reducing the need for glasses or contacts.
The only treatment for a severe cataract is to remove the eye’s natural lens and replace it with an artificial intraocular lens (IOL).
An IOL is a tiny, lightweight, clear plastic or silicone disc placed in the eye during cataract surgery. Unlike contact lenses, which must be removed, cleaned, and reinserted, the IOL remains in the eye after surgery.
Patients with significant astigmatism before surgery will probably require glasses for most activities.
Standard lenses make use of conventional spherical optics technology, meaning when the pupil is large as would occur with night-driving, dim lighting or in fog, some visual distortion and reduced contrast sensitivity will occur.
Accommodating lenses are not suitable for patients with previous eye trauma, or who have unstable support structures for the intraocular lens.
Multifocal/Accommodating lenses are not suitable for patients with significant astigmatism unless additional surgery is performed.
Patients with significant astigmatism before surgery who select a Wavefront Lens will probably require glasses for most activities.Tags: Adult Dating, affair dating, sex dating
