Optimum Infinite is a hyper DK gas permeable material with a unique combination of oxygen permeability and resistance to flexure. Featuring 180 Dk with a flexural modulus of 1500 MPa, it defies the high Dk/low flexural modulus convention.

This breakthrough was motivated by the requirements raised for a dedicated scleral material at several laboratory panel and Key Opinion Leader meetings. Modalities such as sclerals and ortho-k have been propelled into the forefront of practitioners’ attention in recent years. As their popularity has grown, research has identified the need for a material providing a combination of hyper oxygen permeability [1] and a high resistance to flexure.

Optimum Infinite is FDA-cleared for a broad range of indications.

Purpose Made Hyper Dk Material That Breaks With Tradition

Optimum Infinite’s development was guided by the expertise of key industry leaders and speciality contact lens manufacturers requesting a contact lens material purpose-made for modern modalities. Offering hyper oxygen permeability (180 Dk) without impacting on flexure, it also provides excellent wettability and is durable during lens handling and wear.

Optimum Infinite is well suited to meet the oxygen transmissibility requirements for scleral lenses set out in peer reviewed research [1]

Pioneering research and industry support allowed Contamac’s R&D chemists to re-write the rules on Hyper Dk materials.

A Fisherman’s Tale – Melissa Barnett

A Fisherman’s Tale – New hyper Dk material eliminates episodes of microcystic edema

This 60-year-old fisherman’s livelihood was saved, affording him a new lease of life, when he was fit with upgraded scleral lenses made from our innovative 180Dk material.

”When at sea it was impossible to remove my old lenses and I was wearing them for up to 18 hours each day! This was fine at first, but after a few years I began to develop some problems.

I was told that I could no longer wear my lenses for extended periods, however, this would mean the unthinkable – taking early retirement. I wasn’t prepared for this at all, financially or mentally.

My optometrist suggested we try a different lens material, and thanks to my new lenses, I can now go all day without any issues.”

Introducing a new addition to the Optimum family of materials

Optimum Infinite brought life-altering benefits to this 64-year-old patient.

Struggling to change lenses due to his rheumatoid arthritis, the extended wear* that was afforded to him by switching to Optimum Infinite has proven to be life changing.

The corneal edema and endothelial blebs that were present with his previous traditional high Dk lenses are now a thing of the past.

An Innovative, Industry-Led Material

Optimum Infinite: responding to an industry desire for a hyper Dk GP lens material

“As an R&D chemist, working in the contact lens industry is something that I find hugely rewarding, as it gives me the opportunity to develop products which will have a positive impact on the lives of patients.” says Mark Eddleston – Project Leader for Optimum Infinite.

Changing lives is right at the heart of what Optimum Infinite is about. With huge growth in the scleral and ortho-k market, there has been an increasing demand for a premium, Hyper Dk material – one which ticks all the boxes when it comes to fulfilling the needs of ECPs, and patients, alike.

The eye health properties of Optimum Infinite combined with its inherent wettability and hyper Dk, have resulted in extremely positive interest in Optimum Infinite within the contact lens industry.

A PERFECT PAIRING

Optimum Infinite Ortho-k Lenses Now Approved For Overnight Wear

Optimum Infinite offers hyper oxygen permeability (180 Dk), supporting corneal physiology during closed-eye conditions, a critical factor in overnight lens modalities

Its optimised balance of mechanical strength, dimensional stability, and surface performance enables precision manufacturing and consistent lens performance in ortho-k designs.

Your Language, Your Way Read Press Release

Why have so many patients never heard of ortho-k?

Awareness

Participants reported rapid adaptation to the rigid gas-permeable lenses used for overnight reshaping

Initial Experience

Pre study awareness of orthokeratology was low among the adult, symptomatic soft contact lens wearers studied

Comfort & Satisfaction

Subjects experienced significant improvements in ocular comfort over the course of the 3 month study, finding the treatment more comfortable than their previous soft lenses

Recommendation

High levels of satisfaction led to participants being likely to recommend Ortho-k to friends or children for myopia control

Established soft contact lens wearers’ awareness of and initial experiences with orthokeratology. Kim Duong, Andrew D Pucker, Gerald McGwin Jr, Quentin X Franklin, Jared Cox, May 2021.
