No opthalmologist worth their salt will think it's a good idea to sleep in any CL, Even Daily wear ones.You can use 30 day contact lenses that you can sleep in and only need to remove once a month. But only some people can tolerate them due to dry eyes. Some brands can even roughly correct astigmatism.
Lasik is usually successful. Usually. There are rare irreversible complications, and it's not so good if you have super bad vision.
In UK the corrective procedure being promoted as the best results/risk wise is the Lens Implant procedure.
