After cataract surgery. creases where observed in capsule. was this from the surgery?

Yes: But this is unavoidable. Using a jelly filled donut as an example, the cataract would be the jelly and the capsule is the rest of the donut. During cataract surgery, the jelly of the donut is removed and a thin lens is placed in the donut. How thick the donut was originally will dictate how much wrinkling occurs, as the donut shrink-wraps around the new lens.

Capsular folds: The lens implant is usually placed in the natural capsule that your natural lens was contained. That capsular bag can sometimes demonstrate some wrinkles or folds. This can be due to many reasons and is not usually detrimental. If needed a painless and effective laser procedure in office can eliminate the folds if they are visually significant.

No: capsular crease: The lens: usually clear, behind iris; is like a "pillow in a pillowcase". When cloudy/white & affecting vision (halos, glare)surgery needed. Goal: remove top part of pillow case (anterior capsule), remove pillow (cataract), keep back pillow case intact (posterior capsule), place a new lens; Recovery usually less than 1wk; 10-20% risk need laser after 1st surgery.
