The primary difference between a conventional monofocal IOL and an accommodating IOL is the design of these haptics.
In a conventional IOL, the haptics are designed to keep the optical portion of the implant stationary, with no rotation or anterior/posterior movement that could affect vision.
The ciliary muscle, ciliary zonules and lens capsule keep the lens suspended in its proper position inside the eye for clear vision.
In a normal eye (without presbyopia or cataracts), this dynamic process of accommodation adjusts the focusing power of the eye by changing the thickness of the eye's natural lens.
Crystalens and Trulign Toric are premium intraocular lenses (IOLs) that correct presbyopia as well as common refractive errors, enabling an expanded range of clear vision and a decreased need for eyeglasses after cataract surgery, compared with surgery performed with conventional monofocal IOLs.
Currently, Crystalens and Trulign Toric IOLs are the only FDA-approved presbyopia-correcting IOLs for cataract surgery that improve near vision by a focusing process called accommodation.
This is why they are classified as "accommodating IOLs." Both lenses are manufactured and distributed by Bausch Lomb.
Accommodation is a process that enables the eye to adjust its focusing power to provide clear vision at all distances.
The primary difference between these two FDA-approved accommodating IOLs is that the Trulign Toric IOL can correct astigmatism as well as nearsightedness or farsightedness.
When the ciliary muscle is relaxed, the lens flattens to enable clear distance vision.
When the ciliary muscle contracts, the lens thickens, becoming more curved for added magnification for clear near vision.
Like should, the verb ought to does not have a past form.
It is only used with reference to the present and the future.
