Laser blended vision provides a range of benefits, particularly in comparison to traditional monivision solutions, such as bifocal glasses or contact lenses. The key advantage of Laser blended vision is the freedom from reading glasses.
The eye will be checked to ensure the IOL remains in place, and once it has fully stabilised, after about six weeks, vision tests will be used to check whether prescription lenses are needed. [ 35 ] [ 8 ] Where the focal length of the IOL is optimised for distance vision, reading glasses will generally be needed for near focus.
The small improvement in depth of focus with the conventional IOLs enhances uncorrected near vision and contribute to reading ability. [15] Wavefront customized lenses can be used in eyeglasses. Based on Wavefront map of the eye and with the use of laser a lens is shaped to compensate for the aberrations of the eye and then put in the eyeglasses.
An Intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as short sightedness and long sightedness; a form of refractive surgery.
Orthokeratology lens. Orthokeratology, also referred to as Night lenses, Ortho-K, OK, Overnight Vision Correction, Corneal Refractive Therapy (CRT), Accelerated Orthokeretology, Cornea Corrective Contacts, Eccentricity Zero Molding, and Gentle Vision Shaping System (GVSS), is the use of gas-permeable contact lenses that temporarily reshape the cornea to reduce refractive errors such as myopia ...
The add segment of the lens for near vision is the D-shaped area. A bifocal is a lens with two sections, separated by a line (see image to the right). Generally, the upper part of the lens is used for distance vision, while the lower segment is used for near vision. The area of the lens that caters to near vision is called the add segment.
