Your Vision After Cataract Surgery

Choosing the intraocular lens implant for your cataract surgery that best suits your needs is an important component of your visual result, and one Dr. Katz takes very seriously. Using careful measurements and advanced calculations, Dr. Katz will review the results and discuss the various options with you prior to your cataract surgery.

Cataracts and Presbyopia

Presbyopia is the loss of the eye’s ability to zoom in and focuses on objects up close. It typically begins in a person’s 40’s and increases gradually over the years. The condition is alleviated by the use of reading glasses, bifocals or progressive lenses

Monofocal Intraocular Lenses (Monofocal IOL’s)

Traditional intraocular lens implants are called monofocal IOL’s, and they are used to minimize the need for eyeglasses at one distance. A monofocal IOL is most often chosen to correct distance vision, however, this type of lens is unable to correct presbyopia. Even if eyeglasses are needed much less or even not at all for the distance, reading and computer glasses will still be needed to see well up close following the placement of a traditional monofocal IOL that targets the distance.

Multifocal Intraocular Lenses (Multifocal IOL’s)

Another option to correct presbyopia at the time of cataract surgery is the insertion of a multifocal intraocular lens. These lenses allow patients to see both in the distance and close up with increased freedom from glasses. Most patients find they can drive a car, play sports, work at the computer and do some reading without reaching for their eyeglasses. Certain activities such as reading the fine print or working in dim light may still require patients to wear glasses.

If you have cataracts and are interested in more freedom from your reading glasses, ask Dr. Katz if you are a candidate for a multifocal IOL.

Cataracts and Astigmatism

The ideal surface of the cornea has a spherical curve similar to a basketball that allows light rays passing through to bend toward its center and focus on one spot. Corneal astigmatism is when the corneal surface is shaped more like a football, with flatter and steeper curves. This common condition causes the light rays entering the eye to focus on more than one spot, resulting in a blur. This blur can most often be corrected with spectacles or contact lenses. Corrective glasses or contact lenses can still be used to correct corneal astigmatism following cataract surgery.

Toric Intraocular Lenses (Toric IOL’s)

Another option to correct corneal astigmatism at the time of cataract surgery is the insertion of an astigmatism-correcting intraocular lens or a toric IOL. These lens implants can minimize or even eliminate the need for astigmatism correction in glasses or contact lenses after cataract surgery. Dr. K

Prior to your surgery, Dr. Katz will determine if you have corneal astigmatism and are a candidate for a toric IOL.
