Premium Lens Implants
During cataract surgery, artificial lenses are implanted in the eye to replace the cloudy natural lenses. These artificial lenses, known as intraocular lenses (IOLs), were once only able to correct distance vision, leaving patients dependent on eyeglasses or contact lenses for near vision.
New advances in technology have allowed for the development of multifocal IOLs which let patients see clearly both at near and far. Multifocal lens implants are ideal for cataract patients who are opposed to wearing eyeglasses. Another major advance is the development of Toric IOL’s for the correction of Astigmatism.
Toric IOLs are used in cataract surgery for patients with significant amounts of astigmatism. Astigmatism is the scientific term used to denote an oval curvature to the surface of the eye. This causes images to be out of focus. In addition to replacing the cloudy lens affected by cataracts, Toric IOLs correct astigmatism as well as nearsightedness or farsightedness. This lens also features an advanced aspheric platform that improves image quality and increases contrast sensitivity.
Although Toric IOLs are not accommodating and may still require eyeglasses or contacts to be worn, they offer many advantages to patients with astigmatism. Most patients report a high level of satisfaction with the Toric IOL, as it is the only lens to effectively treat astigmatism in cataract patients.
These IOLs contain concentric rings that allow for both distance and near vision. Many of them are associated with glare/haloes that can be bothersome, especially at night. This type of IOL is reserved for patients who absolutely do not want to wear eye glasses and are willing to accept these side effects.
Extended Depth-of-focus IOL
This type of IOL is also “multifocal”. It works by extending your range of focus, however, many people still need reading glasses. There are issues with haloes, but not as bad as with multifocal IOLs.
These are the different types of premium lens implants available for cataract patients. Your doctor will work with you to decide which lens is best for your individual eyes to help you enjoy long-lasting, clear vision at near, intermediate and far distances.
