GARCES FERNANDEZ, Ailén et al. Anatomical and functional results in cataract's surgery by extracapsular extraction of crystalline lens versus phacoemulsification. Rev Cubana Oftalmol [online]. 2011, vol.24, n.1, pp. 64-72. ISSN 0864-2176.

OBJECTIVES: To assess the anatomical and functional results using the techniques of the crystalline extracapsular lens extraction (tunneled with viscoelasticity) and phacoemulsification (phacochop) and also to identify the more frequent complications trans- and postoperative. METHODS: A longitudinal, descriptive and observational research was conducted in 386 eyes with cataract operated on the "Ramón Pando Ferrer" Cuban Institute of Ophthalmology from January to December, 2009 and studied in two groups according the surgical technique used. In 140 eyes a crystalline lens extraction was carried out (tunneled with viscoelasticity) and in 246 eyes with phacoemulsification (phacochop). Authors analyzed the type of cataract, the visual acuity without correction and better corrected, as well as the preoperative and postoperative keratometry cylinder, the transoperative and postoperative complications. There was a postoperative follow-up for three months. RESULTS: There was predominance of women aged 60-80; the mean of visual acuity without correction and better postoperative corrected was similar in both groups (0.6 and 0.8). The frequency of trans-surgical and postoperative complications between both groups not differed significantly (10.7 versus 8.5 %; 13,5 versus 6.5 %). CONCLUSIONS: Both techniques turned out to be effective to achieve visual quality in operated patients of cataract.
