A small percentage of patients may still need thin glasses for specific tasks after LASIK, particularly for night driving or fine detail work. This is more common with high prescriptions and does not mean LASIK failed.
Key Facts
- 95% of patients achieve glasses-free vision after LASIK
- Residual prescription of plus or minus 0.5D or less is common and usually unnoticeable
- Night driving may require thin glasses in 5–10% of patients
- High myopia (above -8D) has slightly higher chance of residual prescription
- Enhancement (second LASIK touch-up) is available if residual prescription bothers you
Guidelines & Tips
- Have realistic expectations — LASIK aims for 6/6 vision, not always exactly 0.00D
- Residual prescription often improves further over the 3-month stabilisation period
- Get a refraction check at 3 months before considering enhancement
- Thin glasses for night driving only are a perfectly acceptable outcome
- Centre For Lasik offers free enhancement consultations if results don’t meet targets
- Ask about Contoura Vision for the most precise correction of higher prescriptions
