Evidence
The Experience Behind the Method
PDDA® was not invented as a presentation framework. It was distilled from work across the complete premium IOL value chain: business, clinics, patients and industry.
1996
Working inside ophthalmology since
Experience built across distribution, clinics, industry and patient education.
9,000+
Unique patient responses
A substantial body of direct patient research into visual priorities and trade-offs.
20M+

Patient education at scale, built by translating clinical complexity into usable language.
Four sources of insight
Built From More Than One Point of View
The method connects evidence that is normally held in separate rooms: the boardroom, the clinic, the consultation and the patient's life.
Business and market building
Oleksii founded and led an independent ophthalmic surgical distribution business. The advisory perspective comes from building markets, supporting premium technology adoption and being accountable for execution — not observing it from outside.
Work alongside private clinics
Decades of collaboration with private ophthalmic clinics revealed where strategy, patient communication, consultation and operational behaviour stop aligning — and why excellent technology can still underperform.
Direct patient intelligence
Years of patient conversations, approximately 9,000 unique research responses and a direct-to-patient education audience created a rare view of how people understand risk, value, visual freedom and compromise.
External scrutiny
The thinking has been developed in public: through invited industry work, scientific and business conferences, and editorial publication in international ophthalmology media.
Visible evidence
Work That Can Be Examined
Published ideas and invited appearances matter because they put the thinking in front of informed audiences — outside a private sales conversation.
Selected work includes publication in The Ophthalmologist and Cataract & Refractive Surgery Today, an invited Bausch + Lomb European keynote, work at the Johnson & Johnson Institute, and conference presentations on patient decisions and premium vision.
What this evidence means
Experience Is the Input. Better Decisions Are the Test.
Reach, tenure and publication do not prove that one universal formula will work in every market. They prove that the method is grounded in a substantial body of real decisions rather than borrowed theory.
Every engagement still begins with diagnosis. The evidence establishes the perspective; the clinic, market and patient reality determine the design.
Apply the perspective
Bring a Real Premium-Adoption Problem.
A focused first conversation can establish whether the issue is strategic, operational, patient-side — or not a PDDA Studio engagement at all.
