A different kind of IOL expertise
Oleksii Sologub is not an ophthalmologist or surgeon, and he is explicit about that. His expertise is different: understanding how intraocular lens technologies create different visual experiences, where their limitations are, and how those trade-offs should be explained before a lifelong decision is made.
From engineer to IOL technology expert
Trained as an engineer, with a master's degree in computer science, Oleksii began working with ophthalmic surgical equipment in Kyiv in 1996, when modern phacoemulsification was only beginning to spread in Ukraine. He worked in technical service, supported the introduction of new technologies directly in operating rooms, and took part in some of the country's earliest cataract procedures using phacoemulsification.
The company connected with most of his professional journey began with Ukrainian production of intraocular lenses and microsurgical instruments. Technomedex Group later developed into a distributor and clinical-integration center for ophthalmic technologies — from diagnostics, laser treatment and glaucoma surgery to phacoemulsification systems and modern IOLs.
Over the years, the company worked with technologies from STORZ Ophthalmics, Chiron Vision, Bausch + Lomb, AMO/Abbott, Johnson & Johnson Vision, 1stQ and Lenstec. This involved more than supplying equipment or lenses: it included technical support, surgeon education and helping clinics integrate new technologies correctly into daily practice.
Within this system, Oleksii progressed from technical service and operating-room support to clinical integration, surgeon education, IOL technology, professional team development and patient communication. He remains a co-owner of Technomedex Group today.
This experience allows him to see lens selection from several sides: optical and clinical evidence, the real capabilities of doctors and clinics, the characteristics of different technologies and the experiences people report after surgery. He knows that a technically successful operation does not always produce the best possible vision for a particular person. Sometimes the problem is not the surgery itself, but that the patient's visual needs, available solutions and the trade-offs of each lens were not explored deeply enough before the procedure.
The patient at the center of the decision
Oleksii works with doctors, helping them explain complex technologies more clearly and connect IOL selection with a person's real needs. He also works directly with patients, helping them understand available options, articulate their visual priorities and prepare the right questions for their surgeon.
A clinic may routinely work with only part of the available market, and a doctor may not always have enough time for an extended discussion about lifestyle, working distances, night driving, glasses dependence and tolerance for optical trade-offs. That does not mean the doctor's recommendation is wrong. It means the patient can benefit from understanding the wider picture and knowing which questions to ask before making a lifelong decision.
Oleksii does not perform surgery, diagnose disease or choose a clinic or surgeon for the patient. He advises people in different countries, and his consultation fee does not depend on the manufacturer, IOL model, clinic or the patient's final choice. His role is to explain technological possibilities and limitations, identify a possible mismatch between expectations and the proposed lens, and help the patient prepare for a meaningful conversation with their doctor.
The final medical decision always remains with the patient and the qualified ophthalmologist or surgeon who has examined their eyes.
Oleksii's professional credo has remained unchanged for thirty years: the patient must be at the center of the decision. This means not settling for a formally successful operation or the first standard answer, but striving for the highest quality of vision that can reasonably be achieved with modern methods for that individual — considering the condition of their eyes, their lifestyle, visual needs and the unavoidable trade-offs of every technology.
Why IOL Adviser exists
Oleksii founded IOL Adviser in 2019 to make complex lens technology understandable without turning education into a sales pitch. It began as patient-education videos and grew into this multilingual platform. He also created the Ukrainian- and Russian-language YouTube channel “NOT an Ophthalmologist” and the English-language channel IOL-adviser.
Across these projects, his patient-education content has received more than 20 million YouTube views. More importantly, the recurring questions revealed where patients most often become confused: distance versus near vision, night-driving compromises, glasses dependence, adaptation, and the difference between an IOL category and a specific model.
Evidence, listening and patient decisions
Over more than a decade, Oleksii has analyzed over 9,000 IOL questionnaire responses and thousands of real patient conversations. This work led to Patient Decision Design™ (PDDA®), his framework for presenting complex surgical options through clarity, realistic expectations and informed consent rather than persuasion.
His writing on patient communication has appeared in The Ophthalmologist and Cataract & Refractive Surgery Today, including articles on patient rapport, fear before surgery and the final stage of the patient journey. He has also spoken about patient engagement in elective eye surgery at industry events, including Ophthalpreneurs 2024.
