An implantable contact lens that corrects vision in nearsighted patients is safe and does not have some of the side-effects of laser surgery. The researchers at the American Academy of Ophthalmology’s clinical journal Ophthalmology said that no patients opting for implantable contact lens have reported increased problems, such as glare halos, double vision, night vision or difficulty driving at night, all of which are the potential side-effects of Lasik surgery.
