Cataract surgery has evolved from a procedure where the objective was solely to remove an obstruction to the visual axis. The surgical procedure has gone through a number of advances from extracapsular extraction of the whole lens nucleus through a large incision requiring sutures, to the use of an ultrasound probe to break up, emulsify and remove lens fragments through small sutureless incisions. More recently, femtosecond laser technology has been applied to cataract surgery. Such advances, combined with developments in intraocular lenses and intraoperative tools to optimise their placement, have led to a high degree of safety and predictability for patients undergoing cataract surgery (Jaycock et al. 2009; Lundstrom et al. 2013).
