CARDENAS DIAZ, Taimi et al. Principles for performance of phototherapeutic keratectomy. Rev Cubana Oftalmol [online]. 2016, vol.29, n.4, pp.652-662. ISSN 0864-2176.

Phototerapeutic keratectomy is used as a treatment tool to manage corneal alterations lasting over ten years. Its development has included the withdrawal of the altered corneal tissue and has set out more complex objectives such as obtaining a more regular surface from the optical viewpoint and increasing health of the outer ocular surface by using the most adequate technique for phototerapeutic keratectomy in order to make good use of the precision of the Excimer laser ablation. At the end of the procedure, it is possible to attain a regular corneal surface that does not generate great scar reaction and acts as adequate substrate to encourage the correct epithelium adherence. In this way, the cornea increases it quality as an optical surface, its transparency; it has less reactive cicatrix and more adherent epithelium. All the above-mentioned prompted the authors to make a search of several published articles in order to describe the principles of phototherapeutic keratectomy, the technique and the indications to perform it. The Infomed platform, particularly the Virtual Library of Health with all the search engines, was used.
