Excimer laser correction of astigmatism: Consistent terminology for better outcomes

摘要

The performance of laser vision correction with the refractive laser has become a routine practice for the refractive surgeon and an established procedure in mainstream ophthalmology. The safety and effectiveness of the technology have promoted the approval of the procedure by regulatory agencies and acceptance by most of the general public. However, patients' opinion of this discretionary surgical intervention is not always positive. The impact on the overall demand for the surgery may be disproportionately reduced because dissatisfied patients (4.6% in a study by Solomon et al.) may discourage many eligible candidates.The elements that cause persistent postoperative visual difficulties are multifactorial and difficult to predict prior to surgery.
