Who Should Not Get LASIK?

This question matters because LASIK advertising often focuses on who can have surgery, not who should avoid it. The patients most protected by a good LASIK surgeon are sometimes the ones the surgeon turns away.

LASIK removes corneal tissue and creates a flap. If the cornea is weak, thin, irregular, inflamed, or dry, the procedure can cause poor quality vision or structural problems. If blurry vision is from lens, retina, optic nerve, or systemic disease, LASIK does not solve it.

Poor LASIK candidates include patients with recent prescription changes, very young patients whose eyes are still changing, pregnancy or breastfeeding-related changes, unstable diabetes, autoimmune disease affecting healing, immunodeficiency, medications such as chronic steroids or retinoids that may affect healing, severe dry eye, blepharitis, active inflammation, glaucoma concerns, uveitis, herpes eye disease, prior eye injuries, prior surgeries, cataracts, keratoconus, or thin corneas.

Occupational and lifestyle issues also matter. Boxing, wrestling, martial arts, military restrictions, aviation standards, police/fire requirements, and visually demanding night work should be discussed before LASIK.

Some patients are poor candidates because of expectations. LASIK should not be chosen by someone who cannot accept any risk, expects guaranteed perfect vision, refuses reading glasses after 40, or is unable to follow postoperative instructions.

Red flags include sudden vision loss, pain, active infection, severe dry eye symptoms, progressive astigmatism, corneal thinning, abnormal corneal topography, uncontrolled eye pressure, or signs of cataract/retina disease. These require medical evaluation, not LASIK scheduling.

The evaluation looks for disqualifying findings through refraction history, corneal mapping, pachymetry, tear testing, pupil assessment, slit-lamp exam, eye pressure, lens evaluation, retinal exam when appropriate, and review of health history and medications.

Alternatives may include PRK, SMILE, ICL, glasses, contacts, scleral lenses, dry eye treatment, corneal cross-linking for keratoconus, refractive lens exchange, or cataract surgery. Sometimes the best plan is to delay and recheck stability.

Do not conceal medical history. Do not keep wearing contacts if told to stop before measurements. Do not choose a center that dismisses risks without explaining them. Do not pressure a surgeon into operating on an unsafe eye.

Patients in Hanover, York, Adams County, South Central Pennsylvania, northern Maryland, and nearby Virginia should call May Eye Care Center when glasses or contact lenses are interfering with work, driving, sports, photography, surgery, outdoor activities, or quality of life. LASIK is elective, so the decision should be careful, measured, and based on a complete medical eye examination—not an advertisement or a discount offer. May Eye Care Center aims to be the MECCA of Eye Care: a trusted regional destination patients return to regularly for eye exams, surgical guidance, and straight answers about whether LASIK or another option truly fits their eyes.

The most important LASIK decision is sometimes not to do LASIK. A careful no protects vision and points the patient toward a safer option.
