Core Tip

Core tip: The requirements for good refractive outcomes in cataract surgery are: (1) standardisation of biometry equipment used for axial length and keratometry measurement and the use of optical or immersion ultrasound biometry; (2) sutureless cataract surgery with “in the bag” intraocular lens placement; (3) an appropriate 3rd, 4th or 5th Generation intraocular lens (IOL) power formula should be used; (4) IOL formula constants must be optimized; (5) under certain conditions, the refractive outcome of the 2nd eye can be improved based on the prediction error of the cataract surgery for the first eye; and (6) results should be audited for refinement and to ensure that standards are met.
