One of the most common questions about LASIK is how long the results actually last and whether vision can deteriorate again. Here is the complete picture on LASIK results and longevity.
Does LASIK Give 6/6 Vision?
Yes — approximately 95–98% of patients at Centre For Lasik achieve 6/6 (20/20) or better unaided vision after surgery. A small percentage achieve even better than 6/6 (referred to as 6/4 or 6/5 acuity).
Is LASIK Permanent?
The corneal reshaping performed by LASIK is permanent. The laser permanently removes corneal tissue — it cannot grow back. For the vast majority of patients, the vision correction they achieve is maintained for life.
Can Vision Change After LASIK?
- Presbyopia (age-related near vision loss after 40): LASIK does not prevent this as it is caused by the lens losing flexibility
- Prescription drift: A small minority (5–10%) experience slight regression, particularly those with very high original prescriptions. Enhancement is available.
- Cataracts: LASIK does not cause or prevent cataracts
Long-term Studies
10-year and 20-year follow-up studies consistently show that over 90% maintain 6/6 or better vision decades after surgery. The procedure’s track record is one of the strongest in all of elective surgery.
