Cataract Surgery · Patient Q&A

Should you treat Dry Eye before Cataract surgery?

Medically reviewed by Carl J. May Jr., MD · American Board of OphthalmologyReviewed July 9, 2026
Direct answer

Yes, treating dry eye first genuinely matters. The tear film is the eye's first focusing surface, so if it is unstable, the measurements used to choose your lens implant become less reliable, and you may be disappointed even after a technically perfect surgery. Treating dryness, blepharitis, or meibomian gland problems beforehand, often with drops, supplements, or lid care, improves comfort and gives us more accurate numbers. A healthy ocular surface gives your surgery the best chance of delivering the vision you expect.

Before undergoing cataract or refractive surgery, it’s important for the surface of your eye, or the ocular surface, to be as healthy as possible. This may help reduce symptoms caused by other eye conditions after your surgery. One condition which often affects the ocular surface is dry eye. This is especially common in older adults and occurs when the tear film cannot properly moisten the ocular surface. Even if you don’t feel any symptoms, it’s possible for dry eye to affect the health of your eyes. Your doctor will evaluate your ocular surface and may suggest treatment before you undergo surgery. Treatments can include eye drops , nutritional supplements, or other recommendations. You may be prescribed one or several of these treatments to reduce the possibility of dry eye after surgery. Because dry eye is a chronic disease, you will need to manage it with long-term treatments. A healthy ocular surface is important for the best cataracts or refractive surgical outcome. Talk to your doctor today about improving the health of your ocular surface.
