That's absolutely not true. My husband and I had both eyes done at the same time. Excellent doctor and excellent results. Also...her sister, Dra. Paulina, is great, too.
ETA: I had my eyes done about 3 years ago, so the policy on one or two eyes may have changed. Also, my eyes were $94,000 pesos but that was because I had trifocals (love 'em!) and one special lens because of bad astigmatism. Frankly, it was worth every penny and I'd do it all again in a NY second.
