Abstract

Background: The way we make a cut in the cornea can affect how well the wound heals, how the cornea works and what kind of vision people have after cataract surgery. Our goal was to compare how stiff the cornea is after we use a laser to make a cut and when we make a cut by hand. We did a study with 72 adults who were having cataract surgery. We divided them into two groups: one group got a cut made with a femtosecond laser and the other group got a cut made by hand. We looked at how stiff the cornea was before surgery. Then one week, one month and three months after surgery. We also looked at how well people could see, how thick the cornea was, the pressure in the eye and if the cornea was the shape. Sixty-nine people finished the study. After three months the people who got the cut made with a femtosecond laser had a cornea than the people who got a cut made by hand. The people who got the cut made with a femtosecond laser also had astigmatism, which means their cornea was closer to the right shape.. Their vision, corneal thickness and eye pressure were about the same as the people who got a cut made by hand. So making a cut with a femtosecond laser seems to be better for keeping the cornea stiff. The right shape after cataract surgery.. It does not seem to make a difference, in how well people can see
