In addition, CRS broke out 754 eyes that were not treated for astigmatism. One hundred six of these patients reported having lost between one and two lines of vision at some point during the 3 months between the operation and the post-operative visit. Many of the remaining 36 regained BCVA after enhancements. Other risks reported in studies prior to 1995 include corneal damage leading to permanent corneal scarring or swelling, droopy eyelid, contact lens intolerance and persistent discomfort. The majority of complications recorded in the early studies were intra-operative.
Researchers expect further reductions as instrumentation becomes more sophisticated.
