Summary: The patient presented with poor tolerance to RGPs. He was initially evaluated with a soft toric which, although comfortable, gave unsatisfactory vision of just 20/100. A specialist keratoconic soft lens design with increased centre thickness improved vision to 20/80. Finally, a design from Lab Keratos which incorporates a much thicker central zone gave improved comfort along with a much-improved visual acuity of 20/25. Currently he uses the lenses for all working hours, and also for football. Despite the much increased centre thickness, after 3 years of wear no signs of injection or neovascularisation have been observed.
