Activity Outline
In this article, Clinical Associate Professor Smita Agarwal discusses options for the correction of astigmatism and the technology now available to ensure optimal patient outcomes.
Ocular astigmatism is a refractive condition that occurs due to unequal curvatures of the cornea and the crystalline lens, decentration and/or tilting of the lens, unequal refractive indices across the crystalline lens, and in some cases, altered geometry of the posterior pole.1 In the modern world, with advancing technology and digitalisation, a patient’s aim is not just clearer vision with correction, but a more focussed vision with little or no correction. Astigmatism, even as low as 0.5D, can cause fuzzy vision that can impact uncorrected visual acuity (UCVA) outcomes. Astigmatism may be corrected postoperatively with the use of glasses and/or contact lenses. However, most patients undergoing cataract surgery aim for good uncorrected vision, at the least for distance, if not all distances.
Learning Objectives
- Be aware of the high prevalence of preoperative astigmatism in the adult population,
- Understand how residual astigmatism post-cataract surgery can affect vision,
- Understand how toric intraocular lenses treat astigmatism, and
- Realise the role of technology in enhancing workflows and patient outcomes.
