Please clarify the citation in the first paragraph, page 667, of the editorial by Dr Packer,1 which was published in the May issue of the Archives. The study that cites that 5% of patients who underwent photorefractive keratotomy could not drive at night could not be reference 6 (publication date, 1984) as it predates the clinical use of photorefractive keratotomy. Which reference is the correct one?
