Manufacturing Process
Our IOLs are manufactured using Diamond Lathing Process that provides unique advantage over other manufacturing methods. Diamond Lathing refers to the process of cutting a desired shape onto a hydrophobic acrylic lens at controlled low temperatures using precisely shaped diamond tools.
Throughout the lathe cutting process, the temperature of the material is controlled and maintained at a level that allows for a very high level of precision when the optical design of the lens is applied to the surface. Accurate temperature control is a critical step of the lens manufacturing process. Maintaining the temperature at sufficiently low temperatures keeps the polymer in the rigid state necessary to apply the optical design on the lens. The lathing process is designed to ensure precision and uniformity in the optical surfaces which contributes to the consistent, high-quality performance of our IOLs, especially our Multifocal IOLs.

"Regen" is a diffractive-refractive combined multifocal lens, ensuring good vision from all distances. To top it all, the Advanced Preloaded System makes the IOL implantation simpler & safer
Clear Vision at All Distances
• With the years of experience in multifocal IOL design, we have come up with the addition of +3.5D power to separate the near & distant images and to make them distinctive
• The light is evenly distributed between all focal points (near, intermediate & distant) resulting in a crystal clear vision from all distances
• The central zone is of 4.2mm diameter has 20 diffractive zones. The remaining 1.8mm portion of the lens has the refractive zone
The IOL is designed in such a way that the step height gradually declines towards the periphery This guarantees excellent satisfaction for the patients allowing them to enjoy the Crystal Clear Vision under all light conditions
Quality & Accuracy
• All lenses are tested for Resolution with Air Force Target immediately after Lathing
• Each "Regen" is individually tested with Optical Bench Sytem called IOLA-MFD for power, quality and MTF for testing near and far focal points
• Each “Regen" is assured of higher MTF values. Higher the MTF value, higher the contrast from all distances and under all light conditions
PCO
• Each "Regen" has 360° Square Edge, Posteriorly offering excellent barrier to PCO
Special Features
• The overall Haptic and Optic design offers excellent centration of IOL irrespective of the capsular bag’s size

Hydrophilic (HEMA) Material
Why opt for Foldable Intraocular Lenses?
The traditional material used in the manufacture of Intraocular Lenses for over 50 years now, has been a clinical grade of PMMA, which has been found to be suitable for implants in the human body
The disadvantage of PMMA is that it is hard and it cannot be folded. Hence, the size of the incision in the eye for the insertion of the actual lens has to be at least as large as the diameter of the IOL
The clear advantage of a foldable lens is the size of the incision. It can be made very much smaller so the trauma caused to the eye during the surgery is considerably reduced and the quality of vision is greatly improved by reducing the Surgically Induced Astigmatism. Hence, the surgery becomes simpler and the patient’s recovery is faster

OTHER IOL
Thanks to latest Nano technology, MULTI DIFF IOLs always yield accurate refraction. Aspheric Optics & innovative Diffractive-Refractive design gives high contrast under all light conditions.
Since 1949 Intraocular lenses have been made of PMMA, due to its lightness, clarity and stability Even today, PMMA is the material of choice. PMMA offers outstanding stability and optical quality for a predictable outcome and maximum performance. Millions of odd eyes have been implanted with our basic and premium range of PMMA lenses with excellent outcome. Thanks to the inherent quality of the material.
SINGLE PIECE - IRIS CLAW
Iris-Claw Lenses are the most reliable option for secondary IOL implantation in both Phakic and Aphakic eyes when no capsular support is present. This precision engineered product of ours is most popular among leading surgeons in India, and is being consistently supplied to leading surgeons/hospitals worldwide. Centration related issues are averted in these lenses and when compared to other Phakic lenses, they have the advantage of preserving the anterior chamber anatomy in Aphakic eyes. After a well performed Vitrectomy, the Iris Diaphragm slightly displaces itself backward, and the implanted IOL maintains a greater safety distance.

A capsular tension ring may not hold the bag in place during Phaco if the Zonules are very weak. Surgeons, sometimes, use the Iris Retractors on the rim of the Capsulorhexis in order to manage this problem. But Iris Retractors aren’t designed for this purpose. Since the Iris Retractor comes in at an angle, the hook is not in the same plane as that of the rim to be supported by it.
In contrast, Capsule Care is designed such that the hook is angled to be in the same plane of the anterior capsule. As a result, it is easy to get a firm and reliable grip on the rim. Further, the tip of the hook is rounded to prevent any accidental damage to the peripheral capsule while placing the hooks in the bag. The round tip also provides a larger support area per hook thereby reducing the number of hooks required in each surgery Once the hooks are placed in position to support the capsule, an Endocapsular Ring can be inserted
Advantages
• Maintains the position of the capsule during Phaco
• Supports the Firnix as well as the Capsulorhexis rim, so that the peripheral capsule isn’t attracted towards the Phaco tip
• Avoids the problem of the Capsular Tension Ring Trapping Cortex
• Prevents Zonular Stress during Nuclear Rotation
• Set of 2 sterile Capsule Care from the Endothelium for better preservation
