Refractive lens exchange is the technique where the natural lens in the eye is supplanted with an artificial lens. This is also called an intraocular lens and is used for cataract removal or cataract prevention. The fact that it is an artificial lens eliminates the risk of cataract developing in the eye and this makes it a widely accepted technique in cataract prevention.
The presence of presbyopia and the beginning stages of cataract development are symptoms that usually surgery will be necessary to the replace the natural lens of the eye. Many patients at this point would rather chose to receive refractive lens exchange over the troubles of deteriorating vision.
The benefits of preemptive refractive lens exchange are:
- Reducing the need for bifocals and reading glasses
- Decreasing the chance of regular vision problems, such as nearsightedness and farsightedness
- Positive alternative to LASIK eye surgery for patients with thin corneas
- Interchangeable intraocular lenses, this allows for vision corrections in the future
- No threat of developing presbyopia or a cataract
Monofocal intraocular lenses (IOLs)
Monofocal IOLs can be implemented to replace the eye's natural lens. This allows for the individual to see clearly at a single point, which is generally at a distance. You would still need glasses for reading or working on a computer, but the advantage is that monofocal IOLs are covered by insurance because it is an necessary component of cataract removal surgery.
The TECNIS® Multifocal Lens allows the patient to see clearly at any distance and under any light condition. This differs from a monofocal lens that only delivers clear vision at a fixed distance. The TECNIS® Multifocal Lens can successfully eliminate the need for glasses following a cataract surgery.
Crystalens HD allows a patient to change focus from close distances to far ones, with every distance in between, making it an accommodating IOL. When this concerns presbyopia, the natural lens is not able to flex and bend and that makes an accommodating lens a useful option.
By adapting to the eye muscles the Crystalens HD bends in the same way the natural lens once did. This will allow for an increased depth of focus and improve a person's vision at a close distance, without compromising a medium or far distance.
There have been fundamental problems with other IOLs. These can include glare, halos and trouble with night vision. Crystalens HD patients have reported a significant lessoning of these issues. Multifocal lenses project multiple images to the brain, while the Crystalens HD only relays a single image. This allows the brain to not have to “adjust” to the different images.
Crystalens HD allows patients to again experience a more natural vision, whether near and far.
An eye's cornea is supposed to be perfectly round. Astigmatism is the result of having an irregular curvature of the cornea. This causes a person's vision to blur due to the inability of the optics of the eye to focus on an object. Toric IOLs are created to offset this imbalance.
Toric IOLs can be a solution to reduce or eliminate corneal astigmatism when a patient is affected by both a cataract and astigmatism. This can provide a considerable improvement of your vision for distances, without the need for contacts or glasses.
95% of all patients with astigmatism report clear vision after refractive lens exchange using a Toric IOL. Patients who have received a standard IOL only have a 25% chance of seeing clearly without glasses or contacts./p>
A Toric IOL lens will stay in place once it is implanted and thus eradicates any pre-existing astigmatism./p>
TRULIGN® Toric Lens
The TRULIGN® Toric lens is the very latest in eye care technology and now is available at our Laguna Hills office. This new lens was just approved by the FDA in 2013 and we are some of the first surgeons to use this leading edge lens.
What is TRULIGN® Toric IOL?
The TRULIGN Toric IOL has been specifically designed for patients with an acute astigmatism that would like to improve their nearsightedness. This intraocular lens has some of the most advanced technology in existence and is capable of correcting up to three diopters (this is a unit of vision strength). This is a substantial improvement for those patients with astigmatism. TRULIGN can provide near vision that no IOL is capable of producing.
TRULIGN's greatest aspect is that it allows the eye to focus on a full range of distances. This is not possible in monofocal lenses that can only help with a single distance.
