You don't need blepharoplasty but rather eyelid ptosis repair as one eyelid is droopy (ptosis). See an oculoplastic surgeon. The procedure can be done under local anesthesia in scarless fashion with quick recovery.
In your case you have a high crease and eye aperture is not as open suggesting eyelid ptosis on that side. That can be corrected with ptosis surgery through a blepharoplasty incision but an in person examination would be necessary to confirm.
