Yes. This complication is also known as loss of best corrected visual acuity. It means that you are not able to see as well after surgery as you did before surgery, even with the best spectacles or contact lens correction given. It most commonly arises from cornea related problems such as corneal haze or scarring, decentred or uneven laser ablation and cornea flap complications. Fortunately, the likelihood of this happening is less than two per cent and there is a fair chance of further vision improvement with time. Loss of best corrected vision occurs is usually limited to difficulty in seeing clearly the bottom few lines of the visual acuity chart.
