Dr. Xis

I’m Dr. Alexandre Xavier da Costa (Dr. Xis), an ophthalmologist specializing in the cornea and ocular surface. I believe seeing is biology, but truly noticing is humanity. My work includes reconstructive therapeutic keratopigmentation, especially for people with monocular vision and eyes with visible changes—always prioritizing safety, ethics, and results that help restore confidence. Here you’ll find clear, practical content on keratopigmentation, dry eye, blepharitis, inflammation, post-operative care, and ocular health, as well as reflections on aesthetics, identity, and quality of life. This channel is for educational purposes and does not replace a medical appointment. Welcome—let’s expand our view.
