The man who invented LASIK looks back — and forward

At the European Society of Cataract and Refractive Surgeons (ESCRS) annual meeting in London, Ioannis Pallikaris, MD, PhD — the ophthalmologist credited with developing and naming LASIK — delivered this year's Heritage Lecture, offering a rare, personal account of how one of the most performed elective surgeries in the world came to be.

Pallikaris traced his path from early corneal research in Zurich and Moscow to a pivotal 1989 ESCRS Congress presentation in Zurich, where he first introduced the concept of laser correction under a stromal flap. His first human LASIK procedures followed, with a landmark 1994 publication in the Journal of Cataract and Refractive Surgery cementing his place in ophthalmic history. He went on to pioneer epi-LASIK and develop the fixOflex ring (EyePCR) for IOL stability and posterior capsular opacity prevention.

Key Takeaways:

• LASIK was born from a desire to overcome PRK's limitations — pain, haze, regression, and inaccurate results — by reshaping corneal tissue beneath a protective flap
• Pallikaris's 1989 ESCRS debut came alongside legends like Fyodorov, Seiler, and McDonald, marking a turning point in refractive surgery history
• He cautioned that emmetropia — the gold standard target — is itself "the perfect imperfection," urging continued innovation beyond current benchmarks

Why it matters: Pallikaris's lecture is more than a history lesson — it's a call to keep pushing boundaries. Understanding the origins of LASIK helps clinicians appreciate both how far refractive surgery has come and where it can still go.
