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, decentered or uneven laser ablation and cornea flap complications. Loss of best corrected vision occurs is usually limited to difficulty in seeing clearly the bottom few lines of the visual acuity chart.

Other attributes of vision may become affected. Foremost of these is a decrease in contrast sensitivity. This means that even though you may have normal 6/6 vision, you have decreased ability to discriminate between shades of grey, especially under dim lighting. This may cause objects to appear fuzzy or greyish. There may also be complaints of excessive light sensitivity, glare, haloes or ghosting. Haloes are “rings” around lights. Ghosting is the phenomenon of seeing a second false image next to the real one. Most of these vision complaints will alleviate with time but in some cases, they may persist indefinitely and affect the overall quality of vision.
