What Not to Do Before LASIK Surgery

Preparing for LASIK surgery involves more than simply showing up at the clinic on the scheduled day. A successful visual outcome depends upon strict adherence to a preparatory timeline involving specific avoidances. These pre-operative instructions optimize the delicate environment of the eye and ensure the most accurate diagnostic measurements possible. Following this structured plan minimizes risks and maximizes the chance for a smooth procedure and predictable healing process.

Stop Wearing Contact Lenses

One of the most significant preparatory steps is the complete cessation of contact lens wear, which must begin well before the surgery date. Contact lenses rest directly on the cornea, temporarily altering its natural shape due to mechanical pressure and oxygen deprivation. This artificial reshaping can lead to inaccurate measurements when the surgeon maps the eye for the laser treatment. If the cornea is not in its natural, stable state, the custom ablation profile will be incorrect, potentially leading to a suboptimal visual result.

The required duration of abstinence varies depending on the lens type worn. Standard soft contact lenses require stopping wear for one to two weeks prior to the initial consultation and procedure. Toric soft lenses, which correct astigmatism, often necessitate a slightly longer break due to their specific interaction with the corneal surface.

Patients who wear rigid gas permeable (RGP) or hard contact lenses require the longest period away from their corrective device. These stiffer lenses exert greater and more sustained pressure on the cornea, requiring four weeks or more for the tissue to fully return to its baseline curvature. Failure to comply with the mandated timeline often results in corneal topography scans that show an unstable or distorted shape, forcing the procedure to be postponed until the measurements stabilize.

Avoid Eye Area Cosmetics and Lotions

Maintaining a sterile environment is paramount in the days leading up to the procedure, necessitating the complete discontinuation of eye-area cosmetics. Products like mascara, eyeliner, and eyeshadow can leave microscopic debris and oily residues that are difficult to remove entirely. These particles increase the risk of introducing bacteria or irritating the eye surface, which could lead to post-operative infection or inflammation.

Patients should also avoid using heavy facial lotions, creams, or strong perfumes and colognes in the 24 to 48 hours immediately preceding the surgery. Ingredients can migrate into the tear film or onto surgical instruments. Vapors from strong fragrances can also irritate the eyes during the procedure and contaminate the sterile air environment.

Thorough, yet gentle, cleansing of the face and eyelids is the only required preparation in the final day before the procedure. Using a mild, non-oily soap helps remove any residual makeup or oils without introducing new foreign substances. This proactive hygiene measure significantly reduces the bioburden near the operative field, contributing to a safer and cleaner surgical experience.

Restrictions on Medications and Substances

A comprehensive discussion with the surgeon about all current medications, both prescription and over-the-counter, is mandatory before the LASIK date is finalized. Certain systemic medications can affect the body’s ability to heal or increase the risk of complications during the procedure. This complex interaction requires careful planning and potential temporary discontinuation of some substances.

Specific prohibitions often include non-steroidal anti-inflammatory drugs (NSAIDs) like high-dose aspirin or ibuprofen, which possess blood-thinning properties. These substances can increase the risk of minor bleeding and should only be stopped under the direct guidance of the prescribing physician and the surgical team. All lubricating or medicated eye drops must also cease, as they can temporarily alter the corneal surface or introduce chemicals that interfere with the laser.

Patients are instructed to strictly avoid the consumption of alcohol in the 48 hours leading up to the surgery. Alcohol can cause systemic dehydration, which subsequently affects the quality of the tear film and the overall healing capacity of the ocular surface. Dehydration can exacerbate the temporary dry eye symptoms that commonly follow the LASIK procedure.

Stopping the use of tobacco products, including smoking and vaping, is highly recommended for several days before and after the procedure. Nicotine acts as a vasoconstrictor, narrowing blood vessels and reducing the flow of oxygen and nutrients to the healing tissues. This impaired circulation can significantly delay the rate of recovery and increase the risk of post-operative complications.

Day-of Procedure Logistical Errors

The most common logistical error made on the day of the procedure is failing to secure reliable return transportation. Patients are legally prohibited from driving themselves home immediately following LASIK because of the temporary visual impairment and light sensitivity caused by the procedure and the necessary use of sedating medication. A responsible adult must be arranged to drive the patient home and potentially assist with initial post-operative care.

Patients should choose their clothing carefully, selecting items that do not need to be pulled over the head. Garments like button-up shirts or zip-up jackets are preferred over sweaters or hoodies. Avoiding contact near the eyes minimizes the risk of accidentally bumping the delicate corneal flap or introducing lint immediately after the surgery.

Bringing small children or dependents who require constant supervision is a mistake to avoid on the day of surgery. The patient needs to remain calm and relaxed before and after the procedure, which is difficult when managing complex childcare arrangements. Securing reliable outside care ensures the patient can fully dedicate their attention to the recovery process.

Finally, the consumption of stimulating beverages like coffee, strong tea, or energy drinks should be avoided in the hours immediately before the procedure. High levels of caffeine can induce anxiety, jitters, and involuntary movements, making it challenging for the patient to maintain steady fixation during the laser treatment. A calm demeanor is important for both the patient’s comfort and the surgical team’s ability to perform the laser ablation precisely.
