In the advanced DSEK procedure, only one or two stitches is needed in the eye. After laying still in the recovery room for an hour, patients are sent home with a patch on their eye and instructions to take it easy for the first day. More than 95% of the time, the new donor cells are in place the next day and normal vision typically returns in 4 to 12 weeks, as opposed to the year-plus following full thickness corneal replacement. The smaller incision also helps alleviate the potential for a weak spot susceptible to future trauma.
