Treatments to Reduce or Eliminate Glasses at the time of Cataract Surgery

A cataract (a cloudy lens in the eye just behind the pupil/iris) interferes with vision by blocking and scattering light that enters the eye; glasses (or contacts) are of limited help because the light is scattered and blocked after it passes through the glasses on its way into the eye. With standard cataract surgery, the cataract is removed and replaced with a clear standard monofocal (single focal distance) lens implant so that glasses (or contacts) work again to help focus for many or all tasks (both near and distant vision) after surgery. Glasses are typically used in these cases to correct myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism to provide focus at a given range (usually distance vision), as well as presbyopia correction to allow for close vision for reading and computers.

Sometimes, a patient may be more dependent on glasses after surgery. An example would be a near-sighted patient who may be able to read without glasses but does need glasses for distance vision in order to drive. Most patients like this choose to see better at distance without glasses after surgery, but with a monofocal standard lens, this means that the near focus without glasses will be blurred, and both distance and near vision may still need astigmatism correction for the best vision.

At the time of cataract surgery, patients may choose optional treatments to reduce or eliminate glasses dependence:

Treatment of Astigmatism:

This treatment reduces or eliminates glasses dependence at a given range of vision (most patients choose distance vision). Glasses are then typically used for reading and intermediate vision, but with astigmatism treated, often only over-the-counter reading or computer glasses work well. Occasionally patients may choose better near vision without glasses instead of distance, for either one (monovision) or both eyes. This treatment includes advanced diagnostic screening tests and customized treatment planning, extended related post-operative care, and astigmatism treatment with Limbal Relaxing Incisions (LRI’s) and/or an Astigmatism-Reducing Lens Implant (Toric IOL) as determined by Dr. Seibel.

Treatment of Presbyopia:

This treatment potentially reduces or eliminates the need for glasses for both distance and near vision. This treatment includes advanced diagnostic screening tests and customized treatment planning, extended related post-operative care, and Presbyopia-Correcting Lens Implant (e.g. Technis Multifocal, ReSTOR, Symfony, Crystalens), with astigmatism treatment as indicated. . The Technis Multifocal and ReSTOR implants give the greatest independence from both distance and reading glasses but with a higher possibility of night glare compared to monofocal implants (standard or Toric); fortunately, the majority of these patients (95%) rate the glare as either mild or moderate, and many notice improvement as time passes following surgery. The Crystalens typically gives good distance and intermediate vision without glasses (about 3 to 8 feet away, good for sports and stepping on stairs/curbs and typically better than a standard monofocal lens implant), and less glare risk than a multifocal implant, but patients generally need reading glasses. The Symfony is a new class of lens called an Extended Depth Of Focus type, and is in between multifocals and Crystalens in terms of glare and dependence on reading glasses.

Femtosecond Laser Treatment:

An advanced technology laser utilizes Optical Coherence Tomography that provides enhanced imaging for Presbyopia and Astigmatism correcting lens implants as well as enhanced precision Limbal Relaxing Incisions (LRI’s).
