Femtolaser assisted cataract surgery (FLACS): Has it proved to be the new revolution in Cataract Surgery?
Delhi Journal of Ophthalmology
The introduction of femtolaser in ophthalmology in 2001 promised to revolutionarize the field with its high precision and safety level, and its multifaceted utility. Used initially in the field of refractive surgery, its high-tech precision promised to bring a paradigm shift in the field of cataract surgery as well, ushering in the era of Refractive Cataract Surgery. Let us introspect how much of that has translated into reality. The femtosecond laser is a focussed infrared laser having a
... aser having a wavelength of 1053 nm with ultrafast pulses of duration 100 fs (100 × 10-15 sec). The laser cuts the tissue through a phenomenon called photodisruption, in which light is absorbed by a nonopaque structure through which infrared light can penetrate, allowing for the generation of a plasma of free electrons and ionized molecules that rapidly expand, collapse, and create microcavitation bubbles. An acoustic shock wave is produced which separates and incises the target tissue. This is in contrast with the other commonly used laser in ophthalmology, the Nd:YAG laser technology, which uses longer pulse durations. The microcavitation bubbles produced with the femtosecond are much smaller, allowing for reduced collateral damage. The precision, minimal collateral damage and versatility make these lasers unique.
