Does LASIK and implanted contact lenses cause cataracts?

Absolutely! The beauty of modern cataract surgery is that with new lens technology, and advanced IOL-calculation formulae, we are more precise and accurate in arriving at our desired refractive end-point, especially for patients with previous refractive surgery. This means that post-cataract correction of myopia, astigmatism and presbyopia is more precise than it has ever been in the history of medicine.

Any laser refractive surgery, whether LASIK, PRK, or SMILE changes the corneal shape. Sometimes more, and sometimes less, depending on the amount of spectacle power that is to be corrected. There are a number of different types of contact lenses, but basically, you can differentiate them into soft versus hard/rigid, and corneal versus miniscleral/scleral. Any of these lenses can be safe to wear after laser refractive surgery, provided that they are properly fitted by a qualified optometrist/ophthalmologist.
