GONZALEZ DUQUE, Yamile et al. Behaviour of the phacorefractive surgery in high myopia. Rev Cubana Oftalmol [online]. 2010, vol.23, n.2, pp. 229-240. ISSN 1561-3070.

OBJECTIVE: To determine the effectiveness of phacorefractive surgery in high myopic patients based on the refractive results and the incidence of complications at "Ramón Pando Ferrer" Cuban Institute of Ophthalmology in a five-year period. METHODS: A retrospective and descriptive study of a universe of 137 eyes from 73 patients diagnosed with high myopia and subjected to transparent crystalline extraction surgery using phacoemulsification technique was carried out at the Center of Microsurgery in "Ramón Pando Ferrer" Cuban Institute of Ophthalmology from January 2003 to January 2008. Eighty eyes of patients who met the inclusion criteria were studied. The following variables were evaluated: age, sex, better visual acuity without preoperative and postoperative correction, best corrected visual acuity before and after surgery, spheral component, induced astigmatism and transoperative and postoperative complications. RESULTS: The predominant age range was 46-55 years accounting for 75 % of the total number. The visual acuity without correction and best corrected acuity improved significantly in over 90 % of the patients after the surgery. Induced astigmatism was not observed in 77.5 % of cases. The incidence of complications was low in 10 %. Retinal detachment was present in 2,5 % of patients. CONCLUSIONS: Despite the controversial nature of this topic, the phacorefractive surgery of the crystalline is an effective alternative for the treatment of high myopias with very good visual results, excellent predictability and stability and low incidence of complications.
