Do you wear contact lenses and are you considering myopia surgery? One of the first instructions you will receive is about stopping contact lenses before myopia surgery, and even before the first measurements. This step often comes as a surprise: why go back to glasses, and for how long? This article explains what lenses change at the surface of the eye, the published indicative timeframes for each type of lens and how to organise yourself during this period.
Why do you need to stop wearing contact lenses before myopia surgery?
A contact lens rests directly on the cornea, the clear surface at the front of the eye that the laser will reshape. Worn regularly, it can temporarily alter the curvature and regularity of that surface. According to the U.S. FDA, contact lenses can change the shape of the cornea for up to several weeks after you stop wearing them, depending on their type.
Yet the laser treatment is calculated from the measurements taken at the pre-operative assessment: refraction, corneal topography, pachymetry. If the cornea has not returned to its natural shape, these measurements may be inaccurate, and the FDA points out that inaccurate measurements can lead to a poor surgical plan and poorer vision after surgery. Stopping contact lenses before myopia surgery is therefore not a formality: it is a condition for the assessment to reflect your eye faithfully.
How long should you stop wearing lenses before the assessment?
The timeframe depends on the type of lens. As a guide, the FDA recommends stopping them before the initial evaluation and wearing glasses full-time:
- Soft contact lenses: 2 weeks before the initial evaluation;
- Toric soft lenses (for astigmatism) or rigid gas permeable lenses: at least 3 weeks;
- Hard lenses: at least 4 weeks.
These benchmarks are general minimums, not a rule that applies to everyone. The ophthalmic surgeon tells you the timeframe suited to your situation, based on the type of lens, how long you have worn them and how often.
What studies show about corneal recovery
Several studies have measured how long the cornea takes to stabilise after contact lenses are stopped. In a series of 165 contact lens wearers evaluated before refractive surgery, significant lens-induced corneal warpage was found in 12% of cases; in the patients concerned, stabilisation took 7.8 weeks on average, ranging from 1 to 20 weeks (Wang et al., CLAO J, 2002).
A systematic review of fifteen studies reports stabilisation in a median of 2.1 weeks for soft lenses and 7.6 weeks for rigid lenses, with wide variation from one person to another (Abid et al., Br J Ophthalmol, 2025). Among rigid lens wearers, more years of lens wear are associated with a longer time to stability (Tsai et al., J Cataract Refract Surg, 2004).
These findings explain why there is no single timeframe: it is the stability of the measurements, not the calendar alone, that validates the assessment.
Why measurements are sometimes repeated
While the cornea is still returning to its shape, test results may change from one visit to the next. The FDA states that measurements may need to be repeated at least a week after the initial evaluation, and before surgery, to make sure they have not changed, especially for rigid lens wearers. Long-term rigid lens wearers may therefore need several visits before a stable refraction is obtained (Tsai et al., J Cataract Refract Surg, 2004).
This check is not a pointless delay: it gives the surgeon reliable measurements to determine, after the pre-operative assessment, the technique suited to your eye.
How to organise yourself during the lens-free period
Going back to glasses for a few weeks takes a little planning. A few practical tips:
- Check your glasses: if your glasses prescription is old, say so, as an unsuitable pair makes this period less comfortable;
- Plan your schedule: sport, travel or special events can be organised with this period in mind;
- Describe your lenses precisely: type (soft, toric, rigid, orthokeratology), how often you wear them and for how many years;
- Avoid putting them back in, even occasionally, without the surgeon's agreement: the timeframes assume continuous discontinuation;
- Bring your previous prescriptions for glasses and lenses: they help confirm that your myopia is stable.
Orthokeratology lenses, worn overnight to reshape the cornea, are also concerned: the review by Abid et al. reports a median stabilisation of 1.6 weeks after they are stopped (Abid et al., Br J Ophthalmol, 2025). They should be mentioned just like any other lens.
And after surgery?
Once the procedure has been performed, the aim is to reduce dependence on glasses and contact lenses, with no promised result: the outcome depends on each person's assessment. In the immediate aftermath, the FDA advises not to resume wearing a contact lens in the operated eye, even if vision is still blurry. The only exception: after PRK, a so-called bandage contact lens is placed by the surgeon to protect the cornea while it heals, then removed during follow-up.
Post-operative follow-up is organised by the ophthalmic surgeon.
The pre-operative assessment with Dr Gozlan
Myopia surgery can be considered from the age of 18, with stabilised myopia. The pre-operative assessment, carried out after lenses have been stopped, allows Dr Gozlan, ophthalmic surgeon, to check the indication and then determine, based on the tests, the technique suited to your eye, including LASIK or PRK. He explains the expected benefits and possible risks. Fees are listed on the Fees page and specified during the consultation.
FAQ: stopping contact lenses before myopia surgery
Should I stop wearing lenses before the assessment or only before surgery?
Before the assessment. The measurements used to calculate the treatment are taken during this examination, so the FDA recommends stopping lenses before the initial evaluation and wearing glasses full-time until surgery.
How long without soft lenses before LASIK?
The FDA indicates 2 weeks before the initial evaluation for soft lenses. The timeframe may be longer in some cases; the ophthalmic surgeon tells you the one that applies to you.
Do rigid lenses require a longer break?
Yes. The FDA recommends at least 3 weeks for rigid gas permeable lenses and at least 4 weeks for hard lenses. In long-term wearers, several examinations may be needed before stable measurements are obtained.
Can I wear daily disposable lenses during this period?
No: daily disposables are soft lenses and are covered by the same instruction. It is preferable to wear glasses full-time until the assessment and then until surgery.
What happens if I did not respect the timeframe?
Simply tell the surgeon. He may decide to repeat the measurements later, once the cornea has stabilised, so that the treatment is calculated on reliable values.
