does Lasik reduce the risk of retinal detachment?

NO.
People who are near-sighted are at an increased risk of retinal detachment. It is true that Lasik (or "laser vision correction") can allow a person to no longer need glasses for distance...however...the risk of retinal detachment is not reduced.
The reason for the above is because people who are near-sighted have "longer" eyes than people who are not near-sighted. As a result...the retina in near-sighted people is more stretched and thinned...and is more likely to develop tears...which can lead to retinal detachment.
Lasik essentially carves the eyeglass prescription onto the surface of the cornea (thus eliminating the need for glasses) but it does not change the shape of the eye...and thus does not reduce the chances of developing retinal tears and retinal detachment.
