Scleral lens fitting for high levels of regular astigmatism

In my February 2016 column, I described how mild to moderate levels of regular astigmatism can now be corrected with orthokeratology. However, for some patients the lifestyle consideration of using ortho-K lenses may not suit, or they may just have too much astigmatism to realistically be a good ortho-K candidate. Hopefully most optometrists will know a rigid lens is the best option for these >3.00DC patients to achieve high quality vision. For the majority of patients an RGP corneal lens will work fine, however for patients desiring comfortable all-day wear and stable vision a larger scleral lens can be a preferable option in many instances.
