Distance vision- The best vision without glasses is typically beyond 10 feet. You may need prescription glasses for your sharpest vision. You will need glasses (readers/bifocal/progressives) for near vision.
Mild near-sighted-intermediate distance- Best vision without glasses is at arm’s reach (desktop computer, countertop), You may need prescription glasses for your sharpest vision. One typically has moderate distance vision and moderate reading vision. Glasses are needed for distance vision and reading.
Near-sighted - The best vision without glasses is at a reading distance. You may need prescription glasses for your sharpest vision. Glasses are needed for distance vision.
Monovision – One eye is targeted for distance and the other for intermediate or near vision. This provides a greater spectrum of vision without glasses. Many patients can be free of glasses most of the time. The tradeoff is the loss of some level of stereo (3-D) perception. Prescription glasses can restore stereo vision as well as provide the sharpest vision at a distance and near.
Not everyone adapts to monovision, and some find it very frustrating. This is typically reserved for patients who naturally have monovision or have used contacts or refractive surgery (LASIK/PRK) to create monovision before the onset of cataracts.
Some patients may be able to trial monovision with contact lenses to determine the likelihood of adaptability.

Catayls Laser is a Femtosecond laser. It is used to perform several steps of the surgery. It does so in a manner that is more precise and gentle than can be done manually. This makes the recovery from surgery faster and reduces the risk of some complications.
The Catayls laser is also able to make small cuts in the cornea in order to reduce astigmatism in patients with mild to moderate astigmatism. This reduces the need for glasses at the targeted vision.
Toric Lens- This is an implanted lens that also corrects astigmatism. This is a beneficial lens for patients with a little more than mild to a large amount of astigmatism. This reduces the need of glasses at the targeted vision.
Panoptic Multifocal lens – This is an implanted lens that acts like a tri-focal, providing either distance, intermediate and near vision. This typically allows patients to be free of glasses most of the time. Good lighting is needed to get the near vision to work. You may need prescription glasses for your sharpest vision and/or reading glasses for dim light (restaurants) or prolonged reading. This lens is not for everyone. It is common for patients to notice halo-like rings, these are more notable during the first 6-12 months after surgery and may persist. The presence of other ocular diseases including common conditions like diabetes, macular degeneration, glaucoma, etc, can limit the success of this lens.
Vivity multifocal (extended depth of focus lens) – This is the newest variant of a multifocal lens. It does a good job of providing distance and intermediate vision. It does so without the halos and glare of the multifocal lens. It does not do a good job with reading distance so reading glasses are still needed. This lens can be successful in patients with other ocular diseases.
