Interesting first week following treatment. Initially very sensitive to light and eyes were a little dry and sore. Following 3 weeks vision improved markedly although at different rates in each eye. After 4 weeks vision was great although needed to keep up with eye drops. Now 3 months following procedure only a little dryness in first thing in the morning and eye drops deal with this quickly and effectively for rest of day. Can get a bit dry when am very tired or have been at computer for long periods over course of working day. Now have 20/20 vision and am more than delighted!!
