Refractive 101: Basics
Top Ten Pearls in Challenging Cataract Cases
Highlights & Evaluation feedback
Refractive 101: Basics was an Introduction to Refractive Surgery organised by the YOP Committee. This exciting and informative session for all Ophthalmologists included lectures on:
Intra-LASIK, LASEK, Corneal Topography, Pentacam analysis, Wavefront treatments, Iris recognition, Refractive outcomes/Algorithm adjustments, Internet based Refractive Analysis & Patient selection.
The afternoon session Phacoemulsification and Beyond covered:
Recent Advances in Phacodynamics, Technological Advances to Reduce Energy Dissipation in Phacoemulsification, Biaxial & Coxial Micro-incision Cataract Surgery and the Keynote Lecture 'Femtosecond Laser Refractive Cataract Surgery' by Professor Michael Knorz from Mannheim, Germany.
Professor Knorz's lecture was a highlight of the day's programme with 100% delegates scoring the topic effective or very effective.
Abstract: Femtosecond lasers have already proven to be a powerful surgical tool to assist ophthalmic surgeons in creating precision thickness flaps in LASIK refractive surgery. The use of femtosecond laser technology for corneal cutting improved the ability of the surgeon to customize the precise dimensions and orientation using computer-controlled registration and treatment software. New, advanced femtosecond laser technology is improving the precision of critical steps in traditional cataract surgery as well as the correction of pre-existing astigmatism. Extremely short laser pulses of one quadrillionth of a second (10^-15s) create bubbles that separate tissue through plasma expansion, shock wave pressure and ultimately cavitation bubbles. Decreased pulse duration reduces the photodisruption threshold and secondary effects allowing closer placement of pulses to create a more precise cutting tool than is possible with ultrasound. When this precision cutting capability is combined with image guided control, such as can be provided with ocular coherence tomography (OCT), the expected result is safer and more precise cataract surgery. Most importantly, the most critical and difficult steps of cataract removal are all performed before the eye is opened to remove the nucleus cortex and implant the IOL. One precise, image-guided laser procedure can effectively fragment the nucleus, create a perfectly centered and sized capsulotomy, complex multi-planar incisions, and accurate incisions to address pre-existing astigmatism.
Femtosecond laser refractive surgery is therefore a new tool which enables us to improve outcomes and safety in premium refractive lens or cataract surgery.
