Conventional vs Wavefront-Optimized LASIK | Modern Ablation Profiles Explained

In this lecture, we begin our masterclass series on modern customized ablation profiles in refractive surgery. This video focuses on the evolution from conventional ablation to Wavefront-Optimized (WFO) ablation and explains WHY modern refractive surgery moved beyond simple refractive correction toward optical quality optimization. Topics covered: Conventional laser ablation Why patients had glare and halos despite 20/20 vision Corneal asphericity and Q-value Prolate vs oblate cornea Positive spherical aberration Cosine effect and peripheral energy loss Mechanism of Wavefront-Optimized (WFO) ablation Peripheral pulse compensation Transition zones and optical zones Difference between Conventional, WFO, and WFG Measuring vs predicting higher-order aberrations Why WFO became the workhorse of refractive surgery Clinical indications and limitations of WFO SMILE and WFO concepts This lecture is designed for: Ophthalmology residents FRCS / FICO aspirants Cataract and refractive surgery fellows Cornea specialists Anyone trying to deeply understand modern excimer laser profiles.
