PIOL corrects refractive errors without removing natural lens. Three types: angle-supported, iris-fixated, and sulcus-supported. Corrects myopia from -5 to -20 D with 3mm ACD. LASIK can correct up to -12 to -14 D
Er:YAG laser uses erbium-doped yttrium aluminium garnet as active medium. Emits infrared light at 2940 nm wavelength. Strongly absorbs water and hydroxyapatite
Veterinary surgery falls into orthopaedics, soft tissue, and neurosurgery categories. Specialists require one-year internship followed by three-year residency. Board certification requires passing rigorous examination
Pulsed lasers produce optical power in pulses of varying durations and repetition rates. Some lasers operate in pulsed mode due to limitations of continuous wave operation. Pulse energy can be increased by lowering repetition rate for better energy buildup
