As we age, our vision naturally changes. Maybe you have a newfound need for reading glasses or are experiencing cloudy lenses. The freedom of renewed sight drives many cataract patients to have the procedure. The ability to see correctly impacts our lives every day. Are you considering the PanOptix Trifocal lens for your cataract surgery? The PanOptix Trifocal lens is an innovative multifocal lens based on the AcrySof IQ IOL used in over 120 million eyes around the world. PanOptix was approved by the US FDA in .

As your top choice for cataract surgery in Dallas, we offer the PanOptix Trifocal intraocular lens (IOL) to replace the clouded natural lens removed during surgery. With three focal distances, the PanOptix Trifocal lens provides clear vision over a greater range than standard monofocal cataract replacement lenses. It provides patients with distance vision, intermediate vision, and near vision.
These acrylic lenses replace your clouded natural lens during cataract surgery, using 26 diffractive rings to provide better near, intermediate, and distance vision rather than the single-distance correction that monofocal lenses provide. This brings you closer to the natural range of vision that most people are used to over their lives, reducing or eliminating the need for glasses as well. PanOptix Trifocal IOLs can correct astigmatism, an important vision concern for many people.
Multifocal IOLs provide a great range of vision, but not quite everything natural sight can provide. There may be a few visual artifacts such as halos, glare, and night vision in a small percentage of patients. On the plus side, they provide a range of clear vision that’s great for active lifestyles. Patients have less reliance on glasses except for special cases such as seeing small details up close (such as needing to thread a needle), and long-lasting vision correction that doesn’t require the cost and upkeep of glasses and contacts.
Cost and personal preference make the choice an individual one. All lens choices can provide improved vision, but the choice depends on whether the patient wants to be free of glasses or contacts. Working with your eye doctor, you can choose monofocal lenses for near vision if your lifestyle suggests it and use glasses for distance vision. Conversely, you can choose to have your distance vision corrected and then only use glasses for reading. If patients have worn monovision contacts in the past and adapted well to them (one eye corrected for distance and one eye corrected for near), monovision vision correction can be achieved with monofocal lenses as well. With multifocal lenses such as the PanOptix, the multiple focal zones provide the maximum range of vision without the help of additional glasses or contacts.
Most cataract surgery patients can see well soon after their operation. Most of the healing occurs during the first week and takes up until about a month for the vision to stabilize. With multifocal lenses, the process for the vision to become clear can take longer as the patient’s brain also must get used to dealing with the new characteristics of vision, like bifocal and trifocal lenses in glasses. Over the next nine to twelve months, the visual cortex will adapt, learning to use the new way that the eye focuses. However, most patients adapt within the first few months after surgery.
Monofocal lenses are suited for a more fixed lifestyle such as desk work and reading or outdoor activities, while multifocal lenses provide more versatility for cataract surgery patients. Accommodating IOLs have been introduced to the market, but multifocal lenses offer the best vision for many patients.
For monofocal lenses, eyeglasses will generally be required after surgery for either near or far vision, depending on the lens prescription. With multifocal IOLs, there may still be a few situations such as reading under dim lighting or driving at night where the clearest vision is obtained by wearing glasses.
PanOptix Trifocal Toric IOLs include correction for astigmatism. Ask your eye doctor if that’s the best astigmatism correction for you after cataract surgery, as there are other possible solutions.
The durable PanOptix Trifocal lens is designed to last a lifetime in most patients. Replacement of the lens is only performed in rare situations.
An outcome of 20/20 vision is quite possible if accurate measurements are taken and there are no other eye health issues present in the eyes. Using multifocal lenses, you may have 20/20 vision without glasses over an extended range, or with monofocal lenses 20/20 over a limited range without glasses.
Have you ever thought about using optical lenses for your product and thought, “There are so many different types and prices to choose from. Which one should I choose?” Just as there are ready-made and order-made suits, there are catalog and custom lenses. In this column, we will introduce the characteristics of these two types of lenses and explain the key points to consider when choosing the lens that best suits your needs.
Refers to ready-made lenses sold on websites or in catalogs.

An order-made lens that is made based on the buyer’s specific optical performance and
specification requirements.
【Pros】
・It can be order-made
・Can meet the required specifications you want
・Specifications can be changed during the production process
(Though, it might cost additional fee during development phase)
・It is easy to generate cost benefits per unit when the purchase volume is high
・Even if you don’t have specific specifications, suppliers can work with you from
the product concept building stage
【Cons】
・It takes time
・There are initial costs for molds, jigs, evaluation machines, etc
・You have to provide a requirements specification
・Without optical knowledge, it is hard to know what to pay attention to and
what are the key points to manufacture a lens
Knowing “what kind of lens you want, when do you want it, and how many do you want” is essential in selecting lenses. Therefore, one of the key points in avoiding problems in lens selection is to follow the above explanation.
【Background】
This is a case in which TOYOTEC made a proposal to a customer who had purchased a catalog lens.The customer wanted to lower the unit purchase price, and asked TOYOTEC if the unit price could be lowered with a custom lens.
【Inquiry Details】
・Quantity：50 pcs / Month
・Product Life：10 Years（120 Months）
・Requirements：A lens unit using glass lenses, design / spec must be same as the current catalog lens
Figure 1: Comparison of Catalog and Custom Proposals
【Results】
The unit price of custom lenses was higher than the unit price of catalog lenses, and there was no benefit to the customer.
【Explanation】
As described in “1. Types of Lenses,” custom lens production requires initial costs for molds, lens jigs and tools, etc. In addition, if the quantity is small, it is difficult to reduce the unit cost of parts from that of a catalog lens. Under the customer’s requirements, there is no benefit in making custom lenses.
Figure 2: Cost Comparison of Catalog / Custom Lenses
However, as shown in Figure 2, the part cost decreases as the quantity of custom lenses increases, so when requesting custom lenses with a focus on cost, it is recommended that multiple quantity requirements be presented.
【Background】
This is a case in which TOYOTEC made a proposal to a customer who had purchased a catalog lens as well as Case 1. This customer had requests to reduce product size while maintaining unit price and optical performance, and asked TOYOTEC if this was possible.
【Inquiry Details】
・Quantity：1,000 pcs / Month
・Product Life：5 Years（60 Months）
・Requirements：Production of a full lens unit. If optical performance can be maintained,
the design can be freely chosen by the supplier.

【Results】
TOYOTEC analyzed the current product and redesigned the lens. As a result, we were able todownsize the lens while maintaining the same unit price and optical performance, thus achieving the customer’s needs.
