Once the surgeon has removed the cataract, a new lens is required to replace it, so that the patient can see. The intraocular lens, or IOL, replaces the natural lens that was removed during the cataract surgery.
A standard lens implant is called the mono-focal. A mono-focal lens allows the patient to only see one kind of distance. Usually, this is distance vision compared to near vision, requiring the patient to wear glasses after their surgery for closer distance activities.
Mr Gangwani can offer you premium implant options. These implant options allow patients to enjoy a more excellent range of vision. Patients are then able to leave our clinic being less dependent on glasses for day to day tasks.
Medical insurance only covers monofocal implants but patients may choose to upgrade to these premium implants and hence will require some out-of-pocket expense (top-up).
Multifocal IOLs allow you to have good vision at both near and far distances. Multifocal IOLs have different levels of power. Each power will diffract light differently. They will also reduce the need for reading glasses or even bifocals.
Toric IOLs are premium intraocular lenses. They’re required if astigmatism needs to be corrected. Astigmatism is when the light cannot be focused on one point on the retina due to eye being shaped like a rugby ball rather than a football. This is due to the asymmetric steepening of the cornea. If it is not corrected, astigmatism can cause blurred or shadowed vision.
Trifocal IOL’s are the most advanced intraocular lenses (IOLs) available today. Much like a multifocal lens, a trifocal lens has many sections set to alternating refractive powers. A trifocal allows for excellent far, intermediate distance vision and even close-up focus.
EDoF (Extra depth of focus) implant: This is an is an elongated focus lens, which means that it provides a continuous range of high-quality vision by extending the focus from distance through into the intermediate and sometimes near range.
Different Types of IOL Available
Visual outcomes are not guaranteed, you should always discuss the most appropriate solution with your eye surgeon.
